Today is our last day at sea. We are scheduled to arrive at Dutch Harbor tomorrow morning at 09:00, and I am a bit sad. After 27 days I feel a part of a new family and do not think I can ever thank the scientists or the crew of the HEALY enough for the amazing experience they have provided.

I have learned science about the Eastern Bering Sea Shelf, I have learned dynamics about the U.S. Coast Guard. The science leaves me wanting more, to delve a bit deeper into this amazing ecosystem that I know so little. The Coast Guard makes me want to talk to students, to let them know about the remarkable career options they could have, and the benefits of such an exciting job.

Everyone works hard to get the research of science accomplished on a cruise like this, but it is important to also have time for play, and to laugh. I have laughed a lot this month, laughed at three in the morning when I grabbed a stinging jelly fish, laughed at eleven at night when I lost in a game of cribbage, I especially laughed when we played a five person round of running ping pong, that also involved spinning. I almost threw up with that one, but the laughter was the most prevalent action.

was told yesterday that if you want too much, or have expectations too high you will be disappointed.  Well I disagree.  I believe in going full tilt into everything I do, and well, I want to do pretty much everything.

We have two more full days at sea and still I am learning.  Yesterday was busy for me, a 22 hour busy day.  The funny thing is, I slept in until 8:30 am, but didn’t go to bed until 6:30 this morning.

It all started with the Webinar and ended with three successive MOCNESS as Alexei tried unsuccessfully to catch pregnant Krill.  But I digress.  Yes the science is winding down, but there is still so much to do.  After the webinar I went to the engine room to watch the successful removal of a piston cylinder liner in one of the four main engines.  Salt water is used to cool fresh water to cool, I think, jacket water that cools the engine.  This is not a typical repair while at sea, but the engineering team in charge knew exactly what they were doing and proceeded with care and skill.

That is actually MKC John Brogan in the Engine.

After the engine room, and dinner I joined FN Angela Ford as she did her TOW rounds.  The TOW (technician of the Watch) is responsible for walking the ship from stern to bow, covering all engineering spaces.  The TOWs are looking for water leaks, electrical concerns, fire, pretty much everything and anything out of place or potentially hazardous.  Even though I had already taken a tour of the vessel this trip was predominantly focused on safety and I was able to see new spaces I had not previously ventured into.

There is a right and wrong way to open, enter and leave all hatches aboard an ocean going vessel.

We even managed to find a crew member I had not previously met, Oscar.  This poor headless fellow is used in man overboard drills as well as other casualty drills during the voyage.  Oscar is also no light weight, weighing in at over 50 lbs he is a great way to practice and for crew members to realize what it would be like to actually work on an injured individual.

Oscar is also the designation of the flag flown when there is a man overboard.

But the day is not over yet, we still had THREE MOCNESS drills to complete.  Alexei wants to find pregnant krill so that he can develop a baseline for aging.  Unfortunately after over four and a half hours of work all we had to show for our labors were some shrimp and krill that were not pregnant, bummer.

This could be a scientist, or a crew member, all we know is that the past 29 days have worked them to exhaustion!

Today will be the last installment of my meet the crew Monday.  There are so many people that I would love to interview and share in this forum, but there is just not enough time in the day.

To start today we have MK1 Allan Whiting, and an amazing list of responsibilities he and his department have on board.  MK stands for machinery technician, and is within the engineering division. Allan’s “A gang” is responsible for EVERYTHING that doesn’t move the ship, thus auxiliary equipment, refrigeration, cranes, hydraulics, water (can make up to 8000 gallons of drinking water a day), winches, therefor a lot of responsibility.

Working on refrigeration is only one part of his job!
Working on refrigeration is only one part of his job!

I think I have previously talked about the scientists as being a web of different fields that drive a bigger picture of how this entire Bering Sea Shelf Ecosystem is changing and adapting with global climate differences.  Well the vessel is not too dissimilar.  Each person, each division is a vital link to the effective and smooth running of the ship, and if the vessel didn’t work, neither would the scientists.

Another responsibility for the “A gang” is the transfer of the starting 1.3 million gallons of fuel from storage tanks while we are underway.  These “A Gang” members are the “FOWK’s” of the vessel; Fuel, Oil, Water, Kings,” and out technical gurus should any fuel casualty occur.  So as you can tell a lot of responsibility with this department.

Where Allan is a lead with the “A Gang,” EM1 Hans Shaffer works with all things wires.  Yes, he is one of our electrical specialists and if it generates, or uses power Hans is part of the team that is responsible for making sure it works.  From all monitoring systems, to the propulsion and even lighting systems, without the electricians the ship wouldn’t move.

While working on the cyclo-converter I stood way back!
While working on the cyclo-converter I stood way back!

Hans also works with the cyclo-converters, and I must be honest, I know that they take 1444 volts at 60 hrtz and convert it to usable power, but that is about all.  This technology is one that I have never studied.  It is a shocking shame I am not more wired in on the intricacies of electricity.  All I know is this electricity is directly proportional to the speed of the propellers and for a vessel, propeller speed is very important.

I usually do only two people on my meet the Crew Mondays, but today I would like to add two more individuals into the mix.  There is camaraderie on this vessel that is amazing, it really is a family.  And a family that exponentially doubles every thirty days or so with the advent of the scientists, yet still all are welcome.  Smiles abound and I have not once felt unwelcome.

FN Angela Ford is one of those people who always has a smile, and who appears to always be learning new skills.  Angela started out in the deck department, and then transferred to engineering (which I have heard is a bit difficult to do).  Angela is also studying to get rated as an YN3, Yeoman third class.  If you see Angela she is either studying, doing rounds with engineering or learning new components of the vessel.  Yesterday while in Aft-Con Angela was supported by the MST crew and took a hand at running the winch to deploy and retrieve the CTD, it was great to watch.  Under the guidance of MST1 Chuck Bartlett, Angela jumped right in, ready to learn something new.  As an educator I was not only impressed with her desire to learn, but Chuck’s patience in teaching.  The whole experience was an educational gift!

Unfortunately I could not stay too long, because I had my own educational experience waiting for me.  The XO, Commander Dale Bateman was preparing to give me a lesson in making a Chocolate French Silk Pie.  Ok, get that smile off your face, because, well, let me tell you, it was one of the tastiest lessons I have had in a while.

For those interested here is the recipe:

(multiply all ingredients times 3 for a standard pie crust)

½ cup butter

½ cup sugar

1 oz chocolate

1 egg

A smidgen of brown sugar

A splash of vanilla

To make this recipe, you first construct a pie crust, then in a mixer blend the butter and sugar.  According to the XO, you can never blend too much.  Add the chocolate and blend, add the eggs and blend some more.  To be precise once all the ingredients are in the bowl blend for at least 15 more minutes, you want this no bake wonder to be frothy and smooth.  Place in a refrigerator over night, and in two hours I will be able to get a piece of our masterpiece, and let you know how the finished product tastes.

I would like to add a special thanks to all those who participated in the webinar today.  It was wonderful to hear your voices, and even better to share with you this amazing adventure of discovery I have been fortunate enough to experience, thank you!

Today is Sunday, and there is change in the air. For one, we have left the sun and re-entered fog. We have also started the 70 meter line back to Dutch Harbor. A large portion of the scientists have completed their work, and each station is now predominantly the CTD, calvet, and optics. With three days left, the tenor of the vessel is mellow, the frenzy of departure just a warm memory. Three full days and then on the morning of the 31st we arrive in Dutch Harbor. I am not ready to leave; there is still much to learn, and this goodbye will be bittersweet. Needless to say I need to get busy; there are words to be written.

I recently received a blog asking questions about the vessel and yes, I have been lax about sharing information about the HEALY and what it is like to live on a four hundred and twenty foot cruising scientific ice breaking mobile command center that floats!

Here are the facts: –Four decks are dedicated to berthing –The Main deck is predominantly the Galley forward, the Engine space a mid ship and the science labs aft. –There are three more decks below the main deck and the bridge above the 04 deck. It is approximately 70 feet from the bridge to the water line. –There is a helicopter hanger and flight deck.

Saturday’s on board the U.S. Coast Guard Cutter HEALY are morale dinner nights. This is when different divisions within the crew prepare, cook and then clean up the evening meal. Well today was the scientists turn, and under the direction of Scott Hiller game on!Right after lunch was served and cleaned, it was our turn to invade the galley. Let’s see, hamburgers, dogs, salmon patties…to start. Potato salad, pasta salad, green salad, and baked beans, were just a few of the accessories. For dessert apple crisp (my contribution) with vanilla ice cream.

It was a lot of fun working with happy people in making other people happy!

When I say we invaded the galley, we really did. Kristen Blattner and I took charge of the crisp, we recruited Chris Moser and the pealing began. There are two types of crisp, the home version when the cook is too lazy to peel apples, and then the social version, naked apples. Once we had our large supply of pealed, cut apples I started the crisp, and having never made such a large quantity before was blown away by the volume of ingredients used.

Once all the fixings were completed it was up to the flight deck. Now was the time for Pat and John to work on grilling the burgers. I managed to get a quick “calvet” in and then helped with the set up.

The clock struck five, crew and scientists arrived, dinner was served. It was a beautiful sunny day, calm seas, perfect picnic weather. No fog in sight.

With all sorts of tasty morsels, no one should have left hungry.

As you might be able to tell, I am about a day behind in my journaling so I thought this would be a perfect time to really explain my “typical” day. One of the hardest parts of explaining a classic day is knowing when to start, because I go to bed when most people are getting up, soooo I will start at six o’clock in the morning and give you a glimpse into a typical twenty four hours.

I have always hated making the bed, now I can just close the curtains.
I have always hated making the bed, now I can just close the curtains.

06:00 Between six and seven in the morning we will have completed our scientific sampling station so I go to bed. There is no fanfare, I collapse!

11:00 The alarm usually rings by eleven, I head down for my breakfast/lunch (today I had chicken nuggets and fries, I know I have a lot of running to catch up on)

Washing down the nets with salt water for any additional copepods.

12:00 Alexei finally trusts me so I take the day shift of deploying, retrieving and collecting the samples from the calvet. Yesterday I did approximately five stations, each 1.5 hours apart. Today I had the calvet stations and managed to squeeze in observing a casualty drill in the “bow thruster void.” This was a training drill, flooding in the compartment with an injury. After watching the drill I returned to the back deck for another calvet.

Notice the size of the hatch, not an easy rescue for an injured person.
Notice the size of the hatch, not an easy rescue for an injured person.

17:00 Dinner, even if I am not hungry no way will I miss this social experience. After dinner Alexei returns and I get work on my journals, talking with scientists interviewing the crew, learning more about how this amazing vessel works. (might squeeze a trip to aloft con to visit with Gary)

20:00 A trip to the mess deck reveals a heated game of trivial pursuit, though my journal is incomplete I sit in for an hour.

22:00 My head is falling over, I need a nap, off to my room for a two hour refresher.

23:00 If interested, Mid-Rats are being offered, our fourth meal of the day.

00:00 Is that my alarm, yes, time to check when the MOCNESS will deploy, night time fishing. As most of Alexei’s team left a week ago I am actually needed, it feels great. While waiting to deploy I again try to work on my journal, and squeeze in a game of cribbage.

After the sampling tow and the work of processing samples begins.
After the sampling tow and the work of processing samples begins.

03:30 We get the deploy signal, and start to fish with the MOCNESS. Remember we are fishing for micro-zooplankton, so no big fish at all. Some evenings the tow is late and we do not begin the station until after four.

06:00 If I am lucky back to bed. There is something to be said for not missing anything and it has been very important to me that I see everything. This is a once in a life time experience, to miss even a single moment would be a moment lost. Oh and I pretty much always skip breakfast at seven, I am unconscious by then. And showering, I will hold off on that story.

Just another wonderful sight from the HEALY.

One of the pleasures while at sea is the concept of time; which is in a word, timeless. Last night the sun set around three in the morning, and if you had asked me what day it was when I went to bed, I could not have answered. I know the date because I made files prior to this cruise so that I could keep track, in some infinitesimal way, of my journals. Right now I know for sure that I am a day behind in writing, that the cruise will be over in less than a week, I still have a lot more science to learn and this afternoon I am making Apple Crisp for the Morale dinner. These things I know, what I am still learning is the science of a sediment trap.Pat Kelly is from the University of Rhode Island Graduate School of Oceanography, and he is here, in part, to collect sediment samples that float in the ocean.

There are many components to the research Pat is working on; one is in collecting particles sinking vertically in the ocean. By using an established brine (denser NaCl) solution in an array of floating tubes Pat is able to catch these falling sediments. The process is to deploy his trap, a series of tubes for the falling sediments held aloft by floats that drift in the ocean, for no more than 24 hours.

After the brine from the sediment trap is filtered and dried the collected sediments will be analyzed.
After the brine from the sediment trap is filtered and dried the collected sediments will be analyzed.

When collected, Pat will remove the sediments from the brine, looking at the thorium and organic carbon, there is a relationship between these two elements and Pat wants to focus particularly on the carbon. Now this is where it gets sticky for me as I am not a chemical oceanographer. Pat is looking at the carbon flux. The team wants to look at the carbon transfer as it changes from atmospheric carbon, to organic carbon in the oceans, thus taking it out of the carbon cycle.

The scientists making sure the trap is ready before being deployed off the back deck of the vessel.
The scientists making sure the trap is ready before being deployed off the back deck of the vessel.

One of the underlying questions in this component of the HEALY research is how the oceans will respond to all the increased carbon due to global climate change. Pat’s group is actually looking at carbon cycling in many different oceans, with their hypothesis: The arctic will respond faster to increases in carbon (changes more apparent, faster), due to decreased ice, and the fact that it is dark for ½ the year. Think of it this way, after a long dark winter with good nutrient build up, a higher yield is to be expected with 24 hours of sunlight. The sinking particles Pat studies are also very important to the benthos species providing nutrients and food as they sink.

The scientists are carefully retrieving the tubes of brine that for the past 24 hours have collected ocean sediments.
The scientists are carefully retrieving the tubes of brine that for the past 24 hours have collected ocean sediments.

Like many of the scientists on board, Pat is doing multiple investigations. The ocean as I talked about before is layered and Pat’s team is looking at productivity in the mixed layer using 02 isotopes. This data will give the scientists the rate that phytoplankton is growing.

The team also uses radium isotopes to estimate advection of deep water to the surface along the shelf break. The information will tie in with the scientists studying iron. There is belief that the iron is up welled from the sediments in the deep water to the surface layers.

I am still learning about the chemistry of ocean science, and do not fully understand all of Pat’s research. I do though see that everything is intimately linked, that all components of this ecosystem are dependent upon each other and if one component is changed then ALL will change as well.

I hope to never be so jaded as to not appreciate the beauty in nature.

Last night I went to bed at four, my wake up call was for seven forty five this morning, needless to say if I have a little difficulty explaining micro-zooplankton there is an excuse.Today I am spending time with Diane Stoeker and Kristen Blattner, both from The University of Maryland Center for Environmental Science.

If she is not at the computer Diane is either at the microscope, the incubators or working on her phytoplankton experiments.
If she is not at the computer Diane is either at the microscope, the incubators or working on her phytoplankton experiments.

Diane and Kristen are studying phytoplankton and micro-zooplankton, and it is amazing how these small components of an oceanic ecosystem are vital for the survival of pretty much the entire environment. Diatoms are small single-celled organisms, called phytoplankton. Diane is studying how fast phytoplankton are eaten by micro zooplankton, and how this “grazing” effects phytoplankton populations.

It is a long process to measure water and extract chlorophyll, Kristen is up for the challenge.
It is a long process to measure water and extract chlorophyll, Kristen is up for the challenge.

Let’s try a visual

Phytoplankton = the microscopic “plants” of the ocean. These organisms photosynthesize and drift with the current. Although some phytoplankton do have locomotive capabilities they cannot swim again the current.

Diatoms are a type of phytoplankton. Zooplankton = small animals who also move with currents and eat phytoplankton as well as micro-zooplankton.

Now enter Diane and Kristen, they look at phytoplankton to find out what is eating them, predominantly micro-zooplankton, and are even looking at their relationship with zooplankton pee and how it might work as a fertilizer for phytoplankton. What these ladies do is collect samples of sea water once a day. They use a mixture of 20% whole sea water and 80% filtered sea water (which removes most of the algae, copepods and protozoa), and a 100% whole sea water sample.

This is part of the larval stage, nauplius of a copepod.
This is part of the larval stage, nauplius of a copepod.

Kristin then strains both types of water pre and post incubation, and will compare the chlorophyll samples. What Kristin is hoping for is that after 24 hours there will be more chlorophyll in the 20/80 sample indicating greater phytoplankton growth, due in part, to the fact that there are fewer predators (micro-zooplankton) in this water. Micro-zooplankton eat nearly 50-60% of the phytoplankton, which they are fertilizing at the same time. This relationship is fundamental to a healthy oceanic ecosystem; you could even say these micro-zooplankton help sustain the growth if phytoplankton in the ocean.

After the 24 hour incubation, samples are taken for further study back at the lab. One specimen they often see is a heterotrophic dinoflagellate. This guy has no chlorophyll and wants to eat phytoplankton; it is in other words a micro-zooplankton.

This little gem does not photosynthesize and locomotors by the little hair like tenacles.

As I look at the pictures Diane has taken, I am transported to a word that is so small that to tell the difference between plant is animal is very difficult.

I have spent the past twenty days discussing science and life aboard a U.S. Coast Guard Ice Breaker, and do not think I have done justice to the “WHY” I am here, and the “WHAT” this will tell us.A grant was written for an extensive five year study of the Eastern Bering Sea shelf, (BEST)The Bering Ecosystem Study. This program involves the collaboration of many scientists, and multiple agencies that research marine ecosystems.

Can you believe it is only ten o'clock at night?
Can you believe it is only ten o’clock at night?

One component of this cruise which I find extremely fascinating is the link between all the sciences of the scientists. It is as if the HEALY is its own food web. Water samples that the krill grazers use are also vital for people studying oxygen, in turn used by people studying phytoplankton, and again by those studying the benthic region, and again by scientists looking at nutrients. Where each team of scientists has their own particular niche of study, or specialty, all together they are making a collaborative map or picture representing the Bering Ecosystem. This data will be used as a benchmark for future research while adding significantly to the knowledge base provided by decades of previous Bering Sea research. The Earth is changing. For scientists it is important to see how these changes will affect the health and productivity of different ecosystems.

From aloft-con the viewing is endless, especially on such a marvelous day
From aloft-con the viewing is endless, especially on such a marvelous day

Today I spent some time with two scientists on board the HEALY that we have not yet met, one of the ornithologists and the mammalogist. First there is Gary Friedrechsen, he spends his day in “aloft-con,” approximately 25 feet above the ship’s bridge, in a little room with a glorious view of the sea. Gary is looking for right whales and works for the National Marine Fisheries Service, a branch of NOAA, and “right” now is looking for the “rights!” Historically considered the “right” whale to hunt due to the fact that they did not sink when harpooned, these majestic beauties were hunted to the brink of extinction. Gary is on the HEALY hoping to get a glimpse of the remnant northwest population who are believed to number less than one hundred. These whales have not been seen in quite some time with surveys dating from 2005 with no whale sightings.

This fall the northwest marine mammal lab will even hire a crab boat out of Dutch Harbor and dedicate two months to finding this illusive pod. The BEST cruise is very diverse because we will now go down the stairs from “aloft-con” to the bridge and there is Tom van Pelt, marine scientist for BSIERP ( Bering Sea Integrated Ecosystem Research Program). Tom spends his day recording bird species found in a 300 meter sampling area port side of the center line of the ship. He uses specialized computer software to log all observations; so that once he enters his user input the computer will attach the longitude, latitude, weather data, and seas to each of his sightings. One of the goals in his part of this project is to try and understand where birds and mammals are feeding. Zooplankton, phytoplankton, even ocean currents all directly drive sea bird distribution, so correlating the observed species with all the other scientific data collected during the day really does allow for the development of an excellent ecosystem model.

When the fog rolls in it is hard to spot bird species, when it rolls out, the landscape is glorious.

One of the great components of the BEST/BSIERP study is that time was written into the grant to take the data collected by the various scientific teams and compile the results. Often grants do not have a lot of analysis time, and in this case there will be a synthesis between all the different teams to make a comprehensive document on the current state of the Eastern Bering Sea Shelf.

Today is “Meet the crew Monday,” and the two sections you will meet today are both fundamental to the smooth running of the HEALY. One, you never want to visit, the other you visit three to four times a day, so with that introduction meet the “Galley, with Tysin Alley” Due to the great quality of the food I usually make it to the galley at least two and in some instances for three meals a day. I am also up most nights and I do not think a day has gone by when I have NOT seen Tysin cooking. He is always there, baking pies, cleaning, boiling crab legs the man never stops.

When living aboard a floating ice breaker, kilometers from land out for 30 days you need to think of priorities, yes maps and scientific operations are important, but full bellies vital. No one wants to work when they are hungry. And to be honest I think many individuals are gaining weight, especially with four meals a day.

There is no shortage of protein on this vessel. And even after 21 days we still have fresh greens for salads.

There is not a time, 24 seven when food is not accessible. Bread and the fixings for sandwiches between meals, always cereal, and in the rare instance when zoning out after midnight a possible taste of something new Tysin has created. And yes, I am one of the few who have gained weight.

The food is hot, fast and readily available, no one goes away hungry.

Since we are now satisfied gastronomically, let’s talk about the Medical division, a place where no one really wants to end up, yet, the proficiency I saw today makes me feel very safe should an injury occur.

From fillings to feet and everything in between the training and skills these men have is beyond excellent.

Jason and Corey are always on, 24 – seven and constantly available should a medical emergency occur. They work with training teams practicing scenarios involving injuries and offer classes to the crew in topics such as CPR. These responsibilities are not only their duty, but a chosen profession to care for the welfare of everyone on board the HEALY.

Spotlessly clean with numerous testing equipment these men appear to be ready to handle any emergency.
Spotlessly clean with numerous testing equipment these men appear to be ready to handle any emergency.

Both men entered the U.S. Coast Guard when they were young, and in Corey’s case 17. Both men also entered as enlisted personnel and choose to go through “A School” as Health Services Technicians. Corey and Jason are also within the five year mark for retiring, with over 15 years of amazing service to the United States Coast Guard…

While talking with Jason I was amazed to follow his Coast Guard career. Here is a sample: Oregon→Alaska→Hawaii→Texas→Nebraska→New Jersey→Virginia→Bering Sea…

…and all this with the total support, financially, and physically, from the U.S. Coast Guard. Jason was also able to not only become a Physicians assistant, but also received a fellowship to do post graduate work at the Navy hospital in Portsmith, Virginia in orthopedics.

I find the career paths of both men fascinating and an excellent recruiting example for the Coast Guard. Two men with high school degrees and now look at them, pretty darn impressive! I am hoping my students take the hint!

Well they can't work all the time!

It is Sunday, I am relaxing. Alexei and I finished our MOCNESS last night around 4:30 am, I looked at copepods for about 30 minutes then went to bed. Got up this morning ( at 9:30am ) for a tour of the medical center and the two men who run it, they will be the focus of tomorrow’s meet the crew Monday, but for now…I am relaxing. There is not another scientific sampling station for about four hours, so it is time to kick my feet back and relax. Yes, all work and no play will make ANYONE dull!

Numerous times over the past two and half weeks I have mentioned the CTD, small ones attached to moorings, there is one on the MOCNESS, there are even CTD sensors aboard the HEALY, but what does this CTD really tell the scientists?

For every sampling station the CTD needs to be prepared ahead of time so that all the equipment is functioning fully.
For every sampling station the CTD needs to be prepared ahead of time so that all the equipment is functioning fully.

As a review, let’s remember that a CTD records the Conductivity of the water that when adjusted for Temperature gives us salinity. The Depth of each sample is recorded because the ocean is not static; it is constantly moving both vertically and horizontally, and changing as it moves. When you sample with the CTD you can add a variety of accessory sensors to measure other ocean parameters: O2 salinity, temperature, pressure, fluorescence, turbidity and on our specific cruise we are also collecting data in regards to micro-zooplankton, nitrates, iron, and radon.

Each line represents a different element that the CTD is measuring.
Each line represents a different element that the CTD is measuring.

Let’s stop for a moment and talk about ocean currents. There are three ocean currents that affect the ecosystems of the Bering Sea: The Alaska Coastal Current, heavily freshwater, colder runoff that shoots through Unimak Pass; The North Pacific Gyre, warmer(relatively) water that seeps through the entire Aleutian chain, like water through a sieve. And the deep ocean conveyor belt, this one actually comes from the Mediterranean…water that has not seen the surface for a thousand years or more! This dense and cold fluid flows through Kamchatka pass, and has traveled from the north Atlantic through the Pacific to get to the Bering Sea, and is really rich in nutrients. No wonder it takes a thousand years. Anyway here we have all this water filtering into the Bering Sea, and here on the HEALY we have the CTD to give us precise data on the composition of this water.

The scientists all getting their water samples out of the 30 liter bottles.
The scientists all getting their water samples out of the 30 liter bottles.

During the actual cast of the CTD at each recorded station 24 data points are collects each second, giving an excellent representation of each specific water column. It is Scott’s job to run the CTD and let me tell you this is no easy task. The electronic equipment has to be constantly calibrated, the physical instrument array maintained, and all the collected data cataloged and stored for transmission to all the scientists both during and at the end of this cruise. None of this is an easy task. I also find Scott’s role on the vessel fascinating. Scott is an engineer who works for Scripts out of California and is hired on as outside technical support. He is not technically one of the scientific team, not technically part of the U.S. Coast Guard, and the HEALY could not technically collect most of their data with out him!

Hamming it up, Scott shows us the real science behind the CTD.

So there I was feeling really confident on my introductory journal on krill only to realize I really knew nothing at all. Tonight I sat down with Alexei Pinchuk and Rachel Pleuthner, wow, I am so impressed with the depth of their knowledge and expertise. But now I am tasked with trying to open a small window into this vital part of an oceanic food web.You have met Kirby the krill, but we should have called him Sam the spud, for the krill is the potato of this ecosystem. These little guys fuel this bionetwork like there is no tomorrow. But I am getting away from myself. Let’s get back to the krill science going on aboard the HEALY.

Part of Tracy's day is spent in front of a microscope keying out different krill species.
Part of Tracy’s day is spent in front of a microscope keying out different krill species.

The krill team is currently involved with at least three different experiments, and I will try to describe each, but please cut me some slack, this is a field of discovery I am just beginning to learn and as Rachel was explaining I would find myself not writing notes and becoming totally engrossed with the discussion.

This machine is one of five different incubators aboard, fresh sea water is constantly run through so that the temperature stays constant for a krill environment.
This machine is one of five different incubators aboard, fresh sea water is constantly run through so that the temperature stays constant for a krill environment.

Experiment # 1: Krill grazing /aging

We already touched on this aspect of the krill work, looking at the diet of krill over a 24 hour period. But what we didn’t hit on was what is then done with the krill after they have grazed. Tracy will measure and key out the specific species of each animal and then pass the krill off to Rachel…Rachel in turn will remove the eyes. Yes, this delicate operation will give a general idea on the age of the krill. Basically our team will extract from the eyes a substance called lipofusion which can then be used to age the krill.

This machine is able to quantify the lipofusion extracted from the krill.
This machine is able to quantify the lipofusion extracted from the krill.

Did that make sense? Because now Alexei comes into the picture, he is trying to actually raise krill in a controlled setting, providing valuable baseline data on how old a krill is to the day. When lipofusion is removed from wild krill it gives a general idea on aging, but is not completely quantitative, thus the two experiments work together to finding the exact age of a krill.

Experiment #2: Starvation is another component to the work the krill grazers are completing. At the start of the voyage, 14 days ago, approximately 20 krill were placed in filtered sea water. What that means is that the krill salad bar was empty. Then, once a week a sample has been removed to look at the lipids. The type of lipids in a krill will tell the scientists what they had been eating, and how the components are breaking down in their systems.

This is actually a female Krill, how can you tell?
This is actually a female Krill, how can you tell?

A krill can live up to three years, with their specific ecosystem and species as two variables that can affect longevity, but what about the source and timing of food. If the juvenile (nauplii – first stage in krill development) hatch when there is no food and they need food well, you can guess what will happen. There are though some krill who store their lipids all winter so that they pass this nutrient source to their young, really fat babies, who are in turn not as dependant on the first zooplankton bloom.

Ughhhhhhh I really do have a beginning understanding to this krill research, but explaining it has been a challenge. I still have more to share, but need to do a bit more of my own fact finding and research.

There can be up to twelve stages in the life cycles of some krill.

To fully understand the today I need to go back two nights. I had been up for over 20 hours and was ready for bed. The educational team and I had been working fiendishly ( love that word) on a power point presentation with fun activities for the students. I was also working on putting together the slides for next Monday’s webinar. Anyway, after dinner, I went to bed. The next I knew my clock said eight thirty, and I had slept 13 hours! Frantically I got up got, dressed, and went to “Aft Con” to check on the retrieval of a floating sediment trap. MST Rich Layman told me that the pick-up would be the next day. I of course disputed his time analysis; it had been 24 hours why weren’t we picking up the trap? Rich of course replied, “We just set the trap this morning, we have to wait 24 hours.” My rebuttal was fun and sassy. There was discussion about a quarter and well to make a long story short. Here it is, I had slept for, you got it, an hour. It was still Tuesday night, I was really confused and a great laugh for many people, including myself. The moral of this story; there really is a purpose for military time!But now it is Thursday, and time to take our traveling science show to St. George. The day did not turn out as we had planned, and with the advent of really thick fog well our adventure was different than what we had planned.

Thus today’s journal will be a photo montage, a sequence of eleven shots highlighting (for me) the pleasure in the day!

(From left) Tracy Shaw, Karen Taylor, Rachel Pleuthner, Megan Bernhardt and Gigi (Virginia) Engel

These five women work nights, waiting until dark to collect their samples.  They only need one sampling station an evening where they send down the “bongo net” and retrieve their live critters.  What the “Krill Grazers” are interested in is: What krill eat, and if their food choice changes seasonally.  They also want to know: if the krill are given a choice, what would they choose to eat.  This is similar to a salad bar mentality, give the krill everything, and see what food they prefer, thus the need for a live experiment.

This krill has a parasite attached, can you find the parasite?
This krill has a parasite attached, can you find the parasite?

For the first part of our experiment, enter Tracy. She is after the live samples and will choose 4 – 8 krill, depending on size.  She will then place the krill in a four liter plastic container with fresh sea water and observe them for 24 hours.  Prior to placing the krill in the container, Megan and Gigi will take a sample of the sea water, and at the end of the 24 hours will take another sample of the same water from the krill containers.  They put the water through a filtering process and preserve the flora and fauna. Megan’s job then continues back at the lab in Washington.  That is when she will count and identify both pre and post samples to determine what the krill are eating.  In the mean time, while still on the ship, at the end of the experiment, Tracy will remove the krill from their incubator, measure them, and figure out what species they are.  This information will be important later when looking at the results of the experiments in order to understand whether larger krill are eating more or different types of food than smaller krill.

When you work all night it is important to have a sense of humor.
When you work all night it is important to have a sense of humor.

The sea water is collected with a CTD so the scientists can exactly match the depth from their live tow on the bongo and the CTD.  So why are five women from three different states (Oregon, Washington and Maryland) working collaboratively on krill?  Krill are a food source for many other species: fish, birds, baleen whales, and many other animals eat krill to live.  Even the seals that eat fish need krill, for the fish have eaten krill.  An oceanic food web is not complete without our little zooplankton buddies.

This BONGO is set up so that the samples are not crushed, thus live krill.

For the past thirteen days I have predominantly been working with the MOCNESS team. These scientists have opened their nets to me, and I have entered a world of plankton, juvenile fish, copepods, jelly fish, crab larva, and even juvenile squid.  There is though one member of our team who I have been remiss in mentioning, meet Ron! Ron Heinz is the head of the nutritional ecology lab for AFSC (Alaska Fisheries Science Center) in Juneau, Alaska. And well Ron collects samples of species and literally blows them up!  Yes you heard me, he combusts his samples.

Ron has a quest, he wants to know how much energy is stored in a fish and how it is partitioned, specifically in either fat or protein.  Basically juvenile fish want protein to help them grow muscle to avoid predators, they also want to store fat for the winter when there is nothing to eat.

The underlying question in Ron’s research is:  what happens to juvenile fish as the climate warms and there is a “mis-hatch” between when the food is available and the fish, hatch.   Ron’s current project is collecting fish, identifying the species, and saving samples for the lab in Juneau.  He will freeze his samples for transport, and then the fun begins again.

The MOCNESS is deployed ready to catch juvenile fish, and other micro critters.
The MOCNESS is deployed ready to catch juvenile fish, and other micro critters.

To extract fat from juvenile fish the process is simple: -Grind up the sample. -Add solvents to the sample to dissolve the fat. (the fat is trapped in suspension with the solvent) -Filter the sample to remove all other “stuff.” -Evaporate the solvent and weigh the left over and voila, you have fat.

Ron and Elizabeth are working together in identifying these juvenile fish; it is not an east task.
Ron and Elizabeth are working together in identifying these juvenile fish; it is not an east task.

To extract protein we now need the other “stuff.”    Nitrogen is found in protein, so simply put, burn the fish sample, remove the CO2 and you have Nitrogen.  Multiply by 6.25 and voila, you have the amount of protein.  To do this he… drum roll please, combusts the sample,  torches it, and poof.  Since there is not a lot of existing data on larval fish Ron is a forerunner in his field.

Ron is ready to collect a sample from this cod-end from on of the MOCNESS nets.
Ron is ready to collect a sample from this cod-end from on of the MOCNESS nets.

Basically Ron is developing nutritional labels for marine species.  He finds out what the different species are made of and in turn can then figure out what would be considered a healthy ecosystem for that specific species.  Right now the target species in his research are pollock, pacific cod, and arrow tooth flounder.  Ron has also made nutritional  labels for other species including a five foot sleeper shark.    In a nutshell his “nutritional labels” tell of metabolic demand, and how who eats whom when and why is so important.

I think I have been up for a day, really bad hair but over 120 fish at this sampling station.
I think I have been up for a day, really bad hair but over 120 fish at this sampling station.

Right now the pollock we are collecting have approximately less than 1% body fat, in the fall it is hoped that they will have 3- 4% body fat so as to survive the winter.  The diet of pollock is predominantly micro-zooplankton.  And for those of you who do not know pollock, every time you eat a fish stick, you are eating pollock! So there you have it “Ron’s World.”  It might be a small and microscopic world but in marine ecology it is very important!

Can you find the pollock, the lumpsucker, and the copepods?

Prior to sailing on the U.S. Coast Guard Cutter HEALY I had no idea what it took to run such a huge floating, moving, science sampling community. Everyone that works aboard appears to be constantly busy not only with their formally assigned duties, but also with collateral duties, so that each one of the 15 separate divisions is constantly hopping. This was the case yesterday for the deck division, the largest aboard the HEALY with 17 crew members.

The deck department working with the scientists to retrieve an optical array.

The ship was working with scientists to retrieve an optical array, thus the need for small boats and the deck crew. It was through the guidance of Chief Boatswain’s Mate Kidd that not only were two boats launched with appropriate crew, but that they had the equipment necessary to try and accomplish their task.

Always prepared Chief Kidd always keeps a sharp lookout while operations are underway.
Always prepared Chief Kidd always keeps a sharp lookout while operations are underway.

Chief Kidd is a career military man who started as a combat photo journalist. It was while I was listening to his account of the past that I learned even more about the history of the Coast Guard and how technology has really changed their world. Chief Kidd used to be a quartermaster, a traditional navigator aboard a sailing vessel. For twelve years he worked on the bridge of ships using tools such as a compass and sextant to plot and record courses. Then came the GPS. Thus the Chief’s “Legacy skills” became obsolete. Now he runs the deck division, responsible for: Having his crew stand bridge watches. Providing bridge lookouts. All small boat operations. Crane operations (not related to science). Armed bear watch when working in the ice. Rescue swimmer when scientists are on the ice. Line tending/deck work…the list is endless.

Working for Chief Kidd is enlisted crew Chelsey Rheyann Kaleoalohalanimalamalama Fernandez. Chelsey works on the Bridge for four hours a day, her primary duty is to record all ship operations while the HEALY is underway. The rest of her time is spent in, of course, collateral duties: maintaining and checking all float coats, checking the weapons locker, checking immersion suits, regular PMS (Preventative Maintenance Systems) checks of small boats and again the list is endless.

Chelsey is new to the U.S. Coast Guard and will have her three year anniversary this winter when she hopes to get accepted into “A School,” to start her training to become a Health Services Technician/Corpsman. There are many opportunities for enlisted personnel within the Coast Guard, and this one will be Chelsey’s path.

I was very lucky when DCC (Damage Control Chief) George Marsden said that I could observe today’s training.   Three teams were involved in this specific drill: Medical, Damage Control and Engineering with approximately 10 people per team observing the actions of the crew as they responded to the reported emergency scenario.

It is very important to prepare for any drill scenario, and make sure it doesn't turn into an actual casualty.
It is very important to prepare for any drill scenario, and make sure it doesn’t turn into an actual casualty.

Our situation is a fire in the number two boiler room with a collateral injury, a crew member with a broken arm.  Prior to the drill all training personnel met to discuss the risk assessment and make sure all safeties were in place so that an actual casualty would not occur.    The crew knows that a drill is impending, they just don’t know the specific details of this drill.  The DCC and I first traveled to the CO2 room to discuss the situation with Chief Kidd who was responsible for simulating the release of the CO2 into the Boiler room compartment.

Making sure that the release of the CO2 system is only a simulation.
Making sure that the release of the CO2 system is only a simulation.

The set up prior to the drill was that a hot work chit (notice) was placed in the engineering control center that hot work was being done in Boiler Room two.  This notice set the stage for DCC Marsden who then began to set up his props for the drill, a smoke machine, identifying flags and a strobe light.  All vital components in alerting the crew as to exactly what casualty they were responding to.

Finally the black smoke flag was placed in front of a shipboard closed circuit camera system and we were off.  Bells and whistles, crew doing exactly as they were trained and I an active observer with a  camera!

Simultaneously on the vessel, boundary compartments are checked, water tight doors closed and ALL personnel are accounted for. Once the CO2 has been activated the fire suppression team waited fifteen minutes before entering the space, and checked the door for heat.  AFFF (Aqueous Film Forming Foam) was also discharged .

Once the all clear was issued for entering the space in went the fire suppression team, with DCC Marsden and me right on their heals.  I was amazed at how effective the smoke machine was, there was literally no visibility.  DC2 Petty Officer Redd had a thermal imaging camera which was used as soon as they entered the space.

Using the thermal imaging camera helps the crew members know more about the intensity of the fire.

Had this been an actual fire it would have taken the crew up to a day and a half to clear the space as safe.  And I was fascinated to learn that in an enclosed space at around 1800° degrees a fire can actually do structural damage, which  to me is terrifying.  And so I say again, thank goodness the crew is trained and maintains these types of training drills so that if a casualty similar to this did occur, we would no doubt be in good hands!

I would say that the smoke machine was pretty effective.

Science Log

Yesterday I watched the deployment of the “Spider C40” a bottom mounted instrument mooring.  Today I will spend some time with Jimmy Johnson as he builds a new mooring, from scratch, right here on the HEALY.

The parts

Jimmy is building a subsurface mooring, but this one is barely subsurface, designed to float about 10 meters below the surface.  But wait a minute, I think I need to back up a bit.  Check out this drawing, the potion of the mooring Jimmy is building is at the tippy top.
BEST N55-08

This is the BEST (Bering Ecosystem STudy) mooring to be deployed on the northwest side of Nunivak Island.

The entire length of this mooring is over 55 meters.  But for our build a mooring experience we are only focusing on the top component of the mooring, which lies at the 10 meter mark.

Jimmy’s mooring has an ISCat, Inductive Sacrificial microCat, phew… This piece of equipment is designed for shallower depths, and works like a CTD, collecting information on the Conductivity of the water, Temperature, and Depth.  This microCat is an inductive device, it uses sea water to complete a circuit (similar to a potato clock) to send the data it collects to the ISCAT logger found 11 meters lower.  So what does all this mean?  If seas get rough, the mooring caught in fishermen’s nets, or the ice gets too thick, Jimmy’s sacrificial mooring has a 600 lb weak link that will snap and sacrifice his creation.  But there is no need to worry, all the data the device already collected has been sent to the logger at the end of the cable, safe from the unpredictable conditions close to surface.  Thanks to this great design scientists are able to sample areas previously un-sampleable do to the conditions I already mentioned.

Voila!

The final product, you can’t see the microcat, it is on the other side.

If you look carefully at the design for this mooring you will see that it includes a:    -Flurometer:  which measures chlorophyll (primary productivity organism) concentrations. -MicroCats (3):  This measures conductivity, temperature and depth. -HOBO sensors:  Temperature sensor to look at the water column and temperature changes. -ADCP:  An Acoustic Doppler Current Profiler sends out a frequency, gets a return signal that has bounced off small animals and or particles that FLOAT/MOVE with the current (not swim) which can give them the speed and direction of the current.

Can you find the microCat?

A scientific work station is a sacred place, there is even a HOBO in here.

Wow, I think my brain is tired, it took a while to understand the concept of the mooring, and then to transcribe was a challenge.  Needless to say these amazing oceanic devices collect valuable data. These records are then used in scientific research papers to better explain and understand the Bering Sea Ecosystem Study, thus BEST!

The nuts and bolts of any operation!

If you need it, Jimmy has it, all the hardware to make a mooring.

**Photo of the Day:*

Waiting to retrieve!

It was a little chilly yesterday as Chief Rieg and MST3 Kruger patiently waited in the cold for the signal to retrieve.

Saying of the Day:  “Rummage Sale” From the original French, Arrimage, a rummage sale historically was when damaged cargo that could not be delivered was sold at cost, or discounted.  As a source of great discounts, the present day rummage sale was originally nautical.  I wonder if Jimmy ever needed a rummage sale while making a mooring aboard a sea going vessel?

FOR MY STUDENTS:  Can you make up a list of the equipment we will need to make our mooring?   I need to add a post script…The deployment of a mooring is not the most thrilling science I have seen on board.  A lot of work, and then, well it is gone.  There is though one part that is a hoot, which I really love.  When the quick release is activated and the 800 lb train wheel plummets to the sea floor, the floats shoot across the surface before they are pulled under.  It is great and reminds me of the movie Jaws!

Science Log

They are the men of the back deck, working diligently to prepare and then release their moorings in depth determined locations, where they will settle (literally) for a year.  These unsung heroes are the mooring men!

For the past week I have been observing a lot of scientific research and much has been based on living critters, but there is so much more occurring on the HEALY this summer.  Under the guidance of Tom Weingartner, the mooring men have been working diligently to not only construct, but then release their moorings which will stay here in the Bering, collect data and then be retrieved, next year!

With various forms of sampling equipment the Spider C40
With various forms of sampling equipment the Spider C40

So what then is a mooring, well this specific example is a bottom mounted instrument, or “Spider C40.” You will notice that the “Spider” is chock full of sampling equipment, there is an: acoustic Doppler current profiler, flurometer, Sea Cat, and transmissometer.  Each one of these instruments is designed to collect specific data, which will be saved then interpreted next year.

The “spider” commonly referred to as Helen, is the second of three instruments being placed on what is known as the central ray to the south of Nunivak Island.  There are three ” mooring rays,” central, southern and northern,  and placed on each will be a series of three mooring. At this time Tom is working on a three year NSF grant. What exactly is Tom learning from this data, well check in tomorrow for a more in-depth look at what scientists learn from moorings? I would though like to go into a bit of detail on the deployment of a “spider” to the bottom of the Bering.

This Spider was deployed in 25 meters of water.  Its objective to sit firmly on the bottom.

AS the winch raises the instrument array, the scientists and MST team work in tandem to make sure everyone is safe and the deployment successful.
AS the winch raises the instrument array, the scientists and MST team work in tandem to make sure everyone is safe and the deployment successful.

Not only is this mooring going to the bottom, but it has two acoustic release mechanisms, one to be used in a year to bring the entire mooring back to the surface, and the other to be used, right now.  For a controlled fall, the spider is securely placed on the sea floor by the MST team using a 3/8inch winch wire. Kevin will then send a 12 kilohertz signal telling the second release mechanism to let go.

Kevin is setting up the electronics equipment necessary to release the mooring after placement on the sea floor.

Once the signal is sent to the acoustic release, the line to the ship is let loose, and then a GPS bearing taken so that in a year the scientists will be able to retrieve the mooring and all the wonderful data it has collected.

Check in tomorrow for a continuation with the mooring men and the science behind why they are setting these moorings, and what they will do with the data.  We will also look at the actual construction of a mooring onboard.

Using the GPS to get an accurate location so that the team can come back for a pinpoint retrieval.

02becce
A pre-drill brief, to discuss props, expectations and safety issues that the trainers might see. If a real casualty happens during a drill, the ETT would let the individuals who are training take control unless there were difficulties in responding to the casualty. Remember a casualty in this respect does not infer human.

At dinner last night I was invited to meet BECCE, and after a moments confusion I realized I had not been invited to meet a person, but to observe a readiness drill.  BECCE stands for Basic Engineering Casualty Control Exercise and I was on my way to watch as the experienced crew aboard the U.S. Coast Guard Cutter HEALY maintains their skills, and passes that knowledge on to new cadets (students from the CG Academy in New London, CT who are here for a month during their summer break) and enlisted personnel. There is an expression in the engineering department, “Slow it down or shut it down,” and that is what BECCE is all about.  Once a crew member on watch finds a problem it is their responsibility to report it to engineering and then take appropriate action, thus BECCE a drill.

The steps to take when there is a problem or alarm in Engineering are simple: investigate the alarm, take initial action to control the casualty, stabilize the plant and report status to the bridge.
Jet fuel has ruptured, pipe spraying leak...the circle indicates people have started to work on the leak. This Brian Liebrecht part of the ETT
Jet fuel has ruptured, pipe spraying leak…the circle indicates people have started to work on the leak. This Brian Liebrecht part of the ETT

This procedure might sound simple, but if 250 gallons of lube oil is rushing from a punctured pipe individuals can easily get flustered.  That is why BECCEs are such a great idea!  Drill, practice and make sure all personnel are prepared for the advent of anything, and you then have a smoother running vessel.

On a side note, as I learn more about the roles and responsibilities aboard a U.S. Coast Guard Vessel I am constantly stumped by acronyms.  The EOW is in charge of the “plant” during this drill and is being evaluated on his responses to the various “casualties”.

LCDR Petrusa (The officer in charge of all engineering on the ship) is observing and watching protocol, with the results of this drill falling on his shoulders.  Simultaneously MKC Brogan evaluates the EOWs during their drill sets.  How about CWO3 Lyons who is in charge of all machinery technicians, both main propulsion and auxiliary divisions? Do you see what I mean, lots of acronyms, and it gets confusing.   Everyone has collateral duties, and don’t even think you can figure out what an OSG is????  I also learned that there are nicknames as well, you could be a twidget (electronics technicians), or a snipe (who are mechanics), sparky (electricians), all of which are vital positions on the boat.  There is a lot of humor as well with the use of slang, for instance I wonder if anyone knows the difference between a Clean EM and a Dirty EM?
This is a fuel oil leak that has not been engaged...the team is discussing the situation.
This is a fuel oil leak that has not been engaged…the team is discussing the situation.

Expression of the Day: “A Clean Slate” Before we had the technology of the 21st century, and there were no onboard computers, or GPS, vital information such as course and distance were written on slates.  At the end of each watch this information was copied into the ship’s log.  The slate was then…”wiped clean.”

Chief Machinery technician Doug Lambert is addressing the casualty during his BECCE drill, while Chief Machinery Technician John O'Brogan observes and evaluates, as a member of EET team.

Nicola studies the early life stages of fish and how they are effected by environmental changes, and how these changes affect their ecology.  Nicola works out of the University of Alaska Fairbanks in Juneau. Alexei studies zooplankton ecology with an emphasis on krill (euphausiids).  Alexei also works for the University of Alaska Fairbanks in Seward. Ron is a biochemist who works for NOAA, Auke Bay Lab in Juneau.  Ron studies fish lipid and fatty acid signatures, and looks at the energy stored in a fish’s body.  Ron also blows up fish, but that I will save for a later journal. Elizabeth is a PhD Graduate student for the University of Alaska Fairbanks, where she works with Nicola studying ichthyoplankton, and also looking at drift patterns with data on abundance and distribution of sample populations.

Nicola is blowing air into the flow meter making sure it is working correctly.

Before I forget, I guess you should know what “MOCNESS” stands for: Multiple Opening Closing Net Environmental Sampling System.  Quite simply a name for a wonderfully complicated piece of machinery.  The MOCNESS actually can take multiple samples of ichthyoplankton (small fish and different types of plankton) at multiple depths while on the same tow, or station.  There is a nine net capacity so theoretically the team can collect nine different samples at one station.

The scientists stand by as the Healy MST crew uses a wench to raise the MOCNESS prior to releasing it to fish behind the ship.

On a last personal note, I have been handling salt water today, so my hands have the most interesting consistency, dry like finely tanned leather.  I have a feeling that this will be the norm for the next month, and though it is not uncomfortable, it is interesting.

Our plane from Anchorage arrived at 12:30 in the afternoon and it has been a whirlwind ever since.  Robert, one of the scientists, and John, the Armada teacher were on my flight so we rented a car and decided to explore Dutch Harbor and the surrounding countryside.

While checking out hundreds of crab pots we found these amazing net structures and still haven't figures out what they catch.

Our first objective was to look for the vessels from the Discovery Channel show Deadliest Catch, and well we found no boats, but lots of crab pots.  It was then on to this amazing coastal road, wow!  What scenery! We spent over four hours driving around the island and even though it was after eight o’clock at night upon our return, the sun was high in the sky when we spotted what appears to be an arctic fox on the bluff on the side of the road.

While driving around the coast of Unalaska, this is the type of scenery we were fortunate enough to see.

“Tough the earth, love the earth, honor the earth: her plains, her valleys, her hills, and her seas: rest your spirit in her solitary places.”     Henry Beston

This could be an arctic fox, and as we watched, it continued to howl in a voice I have never heard before. I still have goosebumps from the sound!

Hello All, This will be my final visit from Alaska, The voyage on the ship is over, but I am far from done with this journey. It is amazing how much life can be packed into a month, and I feel ever so fortunate to have had this opportunity. My heart is full, my mind has been challenged. I am a bit sad as I miss the camaraderie and new friendships, thank goodness for e-mail. Thank you all for your support this past month, my goodness has it ONLY been a month!….hope you enjoy this last entry. Jillian I have attached a photo, hope it works….Also one of my last poems! As the humpback breaches I see a splash, a tail and then nothing. In the blink of an eye this mighty creature has defied gravity. I am in awe! Again and again the aerobatics continue for what reason I do not know, only that as witness I have been given a gift. A tufted puffin paddles by and I am inspired, so glad to have this moment, and so aware of the fragility of life. Seals lay upon floating pieces of ice, their guards down as they relax in pure abandon. I too am relaxed, enjoying the breeze as it plays against my skin. Loving the boats motion, as swell upon swell try to breach our hull. My heart beats to a new rhythm and I am humbled by the grandeur of this place!

Never in my life has a month passed so quickly, literally in the blink of an eye I have had the experience of a lifetime. So much has happened and I am a different woman. Thirty days ago I was prepared to walk in the shoes of another, to taste a different career and learn. Now that time has passed, and the shoes fit so well that I am tempted, so tempted to change the patterns of a life time. NOAA provides an amazing opportunity for teachers and I urge all educators to take advantage of their generosity, for they have enhanced my world beyond merewords.

One week ago I caught my first Halibut, over 50 pounds, and it was quite a challenge to land. I was then taught how to bleed the fish to improve the quality of the meat prior to my lesson on how to fillet. The tender pieces of flesh have been vacuumed packed and will be sent to me for shared consumption. Two weeks ago I hung from the gantry, thirty feet above the deck removing the cotter pin from the block holding the third wire (scientific equipment that sent data back to the ship while we were fishing).My safety was in the hands of men whom I had not previously known, and I had no fear. The pin was tricky, the pliers slippery in my hand, failure was not an option. I was trusted with a job, so there was no hesitation, I would succeed.

Three weeks ago I gutted my first fish, checked its gender, and measured it for scientific purposes. The stomach contents were preserved for further study and the otoliths removed so that the age could be determined. I saw thousands of pollock, and many other species, and have learned to truly appreciate a new ecosystem.

Four weeks ago I stood in Dutch Harbor, Alaska about to board a 215 foot NOAA research vessel with no idea of what was about to unfold. Here I was a teacher from Arizona, about to spend thirty days on the Bering Sea, to study walleye pollock, a fish I had never previously heard of.

Today I am a new person, I have an enhanced understanding of life, of career and the dedication these men and women have to both. I was the student, eager to learn and wanted to be a part of everything.

I was denied nothing for 30 days.  You want to paint Jillian, here are the brushes. What, you really want to clean the heads, go for it.  Ok, I will explain it to you one more time, the line needs to be taught, then you bring the left over the right, through the hole and there is the lover’s knot. (I never did master any knots, but that doesn’t mean I wasn’t an eager study) Once the data is recorded and analyzed, fishing quotas can be established and the Bering Sea can continue to be a viable and healthy ecosystem.

This was my life, and with some melancholy I am sorry to leave. I have made friends expanded my mind, and had an amazing adventure. For many, their days hold no passion, no daily happiness. I have been reminded that life is tenuous, and not to be taken for granted. I want to get up every morning and be pleased with all that I have, and all that I can gain. I want to work with my peers and realize that the little things are not important, the big picture, the smile on my face, the spirit I hold, these are what count.

NOAA, the seventh branch, and least recognized of our military system, has given me a present beyond words, and it is with my every breath that I hope to share this gift with others. Little do my students know what is in store for them this year…as for me the adventure will surely continue!

Science and Technology Log:

The CTD is a device that is hard to explain. Scientific in nature similar to an inverted cone that has a six inch diameter at the top. Today we will look at the condition of the water, the liquid habitat for this ecosystem. Conductivity will give the scientists, with some calculations, the percent of salt in solution. This is important information as the salinity affects the density of the water which in turn affects the speed of sound. Knowing the speed of sound is vital in acoustic fisheries surveys as the scientists use back scatter data in determining fish location and density. The density of water is also affected by the salinity and temperature of the water.

Today’s temperature at 90 meters was 2°C, at the surface it was a balmy 10°C. Ocean water like our atmosphere is in layers, each a distinct unit. The thermo cline was at 35 meters, with a graphic representation showing a distinct differentiation between the two water masses.

The CTD data is used in looking at correlations between where fish populations are found and if their placement is not only affected by the condition of the water, but if there are conditions that they prefer.

Understanding the CTD has been difficult for me. This ecosystem is literally poles apart from a ponderosa pine type forest. I am learning an amazing amount of information and at the same time realizing how much I do not know. Oceanography is an amazing science, and phenomenally diverse.

Once again I spent an hour on the bridge, 2400-0100, standing watch. I did not realize that this nautical term is in fact correct as there are no seats on the bridge except the CO’s chair which is off limits. I was told that there is a common yarn that the captain’s chair is directly above his stateroom, and attached to a bell. If someone sits in the chair the bell will ring indicating that sacred territory has been breached. When a person stands watch for four hours, they stand watch. There are some counters with cushions to brace against, but that is it. While standing watch last night I got my first glimpse of a dall’s porpoise. The pictures that are commonly seen of porpoises show the entire animal usually gliding gracefully with a wave. Our view last night was a glimpse, a peak into the life of a marine mammal. It was Mark, the field operations officer who first spotted the sign, a brief splash within the bow wave of the boat. The porpoises travel the wave of a boat, literally catching rides. At one time there was the splash of three heads effortlessly coming up for air, a brief splash and again they were lost in the wave only to be seen moments later literally in the same place even though we were all moving forward.

There is a calmness here when the fog moves in, a sense of peace. We are out of touch with time, yes there are news briefs, but one does not need to read what is going on in other places. I am ok with the solitude, the sound of the engine the gentle rocking of the boat. This is a serene place to be, in summer!

Haul Data – Methot
Depth of haul: 20 meters
Temperature at depth: 7° C approximate
Species breakdown: walleye pollock year 0, Amphipod- type of crustacean, Chrysora jellyfish

Science and Technology Log:

The Methot haul is when the nets are set out, but at the end there is a cylindrical tube of PVC. It is this tube in which the sample will be taken. Holes are drilled in the side to let the water run through, but there is a mesh screen which prevents the specimens from escape. The purpose of the Methot trawl is to collect younger samples of fish, and as the younger pollock tend to stay higher in the water, and this device is perfect for sampling. Most of the pollock were year zero meaning that they spawned this past April. There is also a relationship between the juvenile pollock and the jellyfish as the Jellies (common term) provide shelter for the young fish. Walleye pollock are cannibalistic and will eat younger smaller fish that could well be their own children.

One of the scientists on board Taina Honkalehton has just returned from Tasmania where she was contracted by the Australian government to study orange roughy, a species that has been over harvested that they are now trying to save as a viable harvest species. Pollock on the other had is a well managed species, where at this time approximately 20% of the population is being utilized for commercial ventures. Pollock are the fish of fish sticks, a very important economic product on a global scale, with pollock as the largest single species fishery in the world making oceanic ecosystem management very important. Approximately 1.8 million tons of Pollock are harvested annually. Part of the management plan for pollock is based in part to their relationship to the stellar sea lion. As an endangered species management needs to look at fish harvesting and see if there is a relationship between the decline of the sea lion and changes in fish numbers.

Personal Log:

Running late tonight, having too much fun gutting fish, measuring jelly fish and cleaning. I have often wondered the purpose of jelly fish. As an Easterner by birth my only experience has been the Portuguese Man of War, the stinging variety that invariably closed our local beach. The jellyfish we have been seeing not only provide habitat for many other aquatic species, but that are also a nutritious food source. Monterey Bay Aquarium has a wonderful display of jelly fish. An amazing species, so beautiful in their basic simplicity.

I promised I would talk about the spinner, which no one has been able to give me a scientific designation for. This amazing piece of technology is a circular window approximately two feet in diameter, the ships windshield. During winter months the entire window of the bridge often freezes up, and this device, through the use of centrifugal motion, manages to keep an area clear for viewing. The glass of the spinner, you guessed it, spins at a very fast rate thus keeping the viewing surface clear.  It is a funky tool, and so far my favorite on the bridge.

Haul Data
Depth of haul: 89 meters
Temperature at depth: 4.1° C
Species breakdown: walleye pollock, chum salmon, smooth lumpsucker, unidentified jellyfish

Science and Technology Log:

First haul of the evening and to our surprise pulled up a smooth lumpsucker (Aptocyclus ventricosus). What an amazing fish quite large in girth, but relatively short( approximately 10 inches). A large globe shaped body with the ventral sucking disk. We placed the fish in water and released it back into the Bering.

As for the rest of the catch, quite a few chum salmon this time, so I anticipate some smoked snacks tomorrow. I am becoming more and more comfortable with the process of slicing the fish to determine gender. Tomorrow will attempt the removal of the otoliths. Amazing the data that can be removed for the preservation of an ecosystem. We are off to complete another haul right now, so I am off to don my rain gear: thick rubber pants, rubber boots, and rubber jacket. I must also wear a hard hat and life jacket when on deck while the cranes are in motion and the ramp is down. With the ramp down it is easy access to the ever cold Bering Sea.

Personal Log:

Well I did it, finally tackled the treadmill, what a treat. My body had wanted to jog for days so in thirty minutes this morning I completed three miles, and for the first time ever I was jogging below sea level as the workout room is toward the bottom of the boat. Amazing the difference between 7000 feet and sea level. The way the treadmill is situated it rocks back and forth not side to side, it is similar to walking rises, with an uphill climb every now and then.

I also spent some more time in the bridge today. I would like to learn all the equipment so tonight I was taught about the EOT (Engine Order Telegraph) The one instrument on the bridge that actually looks familiar as it has probably been in every old war sea movie ever made. You know the big round brass machine with a level and an arrow, and the person on deck moves the arrow to face the command they would like sent to the engine room. The commands vary from full ahead to slow, half even stand by. Now with modern technology this apparatus is obsolete, but still on board in case of emergency and the electronics fail.

I was also introduced to an amazing centrifugal force windshield washer, but those details will have to wait until tomorrow.

Visibility: closing 5-8 nm fog Sea Water Temperature: 7.9C
Wind Direction: 214 Barometric Pressure: 1028 strong high pressure
Wind Speed: 5 kts Cloud Cover: complete

Science and Technology Log:

The plan for tonight is to run a MOCC trawl to test the equipment prior to live sampling, but lets back up a moment and look at the device used for this fish collecting experiment. Originally known as the KMOCC (Karp Multiple Opening and Closing Codend), the MOCC as it is commonly known is a scientific piece of equipment designed to allow scientists to selectively sample specific layers in the ocean. MOCC has the ability to collect fish samplings from a maximum of three different stratum, allowing the scientists choice. Pollock of different sizes tend to congregate at different oceanic layers and through the use of equipment like the MOCC scientists can look at sonar and choose from which population they would like to sample, without contaminating the haul with fish from different size groups. This form of selective sampling will aid the researchers in observing specific fish (pollock) populations.

Today there have been no fish trawls as according to the sonar data the ships transects have not passed any significant fish populations.

Personal Log:

I am on a 215 foot research vessel, touring the Bering Sea looking for walleye pollock, and can sit at this computer for an hour, watching the sonar all alone. With over thirty individuals living on this floating community it never ceases to amaze me that the schedules can be so well devised as to allow people their individual space. With a spare moment one might even be seen sitting in their stateroom relaxing. This amazing personal space is a person’s home away from home and usually has two residents. Each individual will work mirror hours so that while one person is sleeping, the other is working. Why is this fact so important? Well let me explain to you how many staterooms on the Miller Freeman are designed.

As you enter a stateroom there is on one side a set of berths, similar to a bunk bed, but Spartan by necessity. Each berth is approximately three feet wide and two feet high. Not a lot of room for movement, but functional in the processing of sleep. After the berth there is a spartan sink, a small desk, and two built in closets, all in a space that is eleven feet long and approximately five and a half feet wide. (Please realize that the 5.5’ included the beds, closets everything, so walking space is at its best at 2.5’ in the very middle.) The closets are not standard sized actually they are miniature and already contain your personalized life jacket and survival suit. Once inside the survival suit though you might have more room than in your berth. Space aside the rooms are functional, and a little cozy. I have slept in my berth for a few nights, and with the rocking of the boat and the lull of the engine it is as comfortable as an old porch hammock, on a warm summer evening as the breeze lulls you to sleep.

Haul Data
Depth of haul: 78m
Temperature at depth: 4°C
Species breakdown: Walleye Pollock / Chum Salmon / Jellyfish

Science and Technology Log:

Our first haul for this second leg of the Bering Sea MACE (mid-water assessment and conservation engineering) survey (July 5 – August 1, 2004) was completed at 20:00 with the predominantly walleye catch having been measured for length and the otolith ( ear bone) removed. At this point a data base was established to facilitate in the maintenance and establishment of quotas for fisheries management.

Fisheries Biologist Kresimir Williams recorded the data from the haul; fish length, weight, and maturity status. This is very critical information as the Bering Sea pollock fishery is one of the most successful and healthy fisheries in the world. It is this data that is used to determine how large a catch a commercial vessel can remove for each fishing season. Kresimir has been a fisheries biologist for almost six years researching pollock and developing data streams to assist the North Pacific Fisheries Management Council in determining catch limits.

Personal Log:

I am working the four to four shift; four in the afternoon to four in the morning, heck of a schedule for a summer vacation. The best part of this phase is that with the northern summer daylight, you never feel tired; it is light all the time.

This is an amazing experience, an opportunity to see how others live. I have managed to meet everyone on the boat from the Captain CO, to the Chief Scientist, and find it amazing the lives they have chosen to lead. Thrust into this diverse world I am able, ever so briefly; to see how others live, how they earn a living, make daily contributions to society, find happiness.

The Miller Freeman, as I have been told has one of the most rigorous schedules within the NOAA task force, with approximately 260 days a year at sea. Many of the crew considers this vessel the workhorse of the fleet, managing to collect data that is vital in fisheries management. It is also amazing to observe the crew and officers on board as they have super attitudes, considering they spend approximately nine months away from their families. I have though been told that as the days get longer (actually shorter) and we get closer to our thirty day mark that the moral officer has to work a bit harder to keep spirits elevated. All I know is that I have been welcomed into all aspects of this vessel, from the engine room to the galley, the scientific labs to the weight room. Today I learned how to sex a fish, ever so basically; I mean can anyone think of a better way to spend a vacation?
