The data has been downloaded. The instruments have been cleaned and removed from the buoy. The lines and winches and capstans have been removed from the Hi’ialakai‘s deck. It’s all been packed away into a a shipping container, headed back to the East Coast. Next summer, it will all be shipped to Hawaii again, to head out to Station ALOHA for another year at sea, as part of the WHOTS-15 buoy deployment.

As I sit in the gate area at the Honolulu International Airport, waiting for my flight back to New York City, I’m thinking about everything I learned in my time aboard the Hi’ialakai. I’m thinking about the best way to convey it all to my students — because I love using data in my classroom. One of my favorite things to do, when I am introducing a topic, is to give them a data set — either raw numbers, graphs, or other visualizations — and have them draw some preliminary conclusions. What is the data doing? Are there trends that you notice? Does anything stand out to you? Look weird? Because I teach Earth Science, there is a wealth of publicly available data, from the USGS, from NASA, from NOAA. For just about anything I choose to teach, from the atmospheres of exoplanets to mass extinction events, a quick Google search almost always yields useful, peer-reviewed, scientific data. However, until I had the opportunity to sail aboard the Hi’ialakai and observe the deployment of the WHOTS-14 buoy and the retrieval of the WHOTS-13 buoy, I never quite appreciated just how difficult obtaining all the data I use could be.

Despite my best efforts, I think my students still believe that science is a solitary pursuit — something done by people in white coats in a lab somewhere. I hope that my experiences aboard the Hi’ialakai will help me paint a more realistic picture of what science is all about for my students. It’s a highly collaborative profession that needs people with all sorts of skills; not only science, but computer programming, mathematics, technology, logistics, resourcefulness and patience. I also hope be able to impress upon my students just how difficult doing good science can be. I know that I will certainly never look at the data sets I download with just a few clicks of my mouse the same way again.

Personal Log:

I would like to take this opportunity to say mahalo nui loa (thank you very much) to everyone aboard the Hi’ialakai for the WHOTS-14 cruise — for answering all my questions, even the ones I didn’t think to ask; for sharing data, seasickness medication, hardhats, and the occasional power tool; for the fabulous meals (and the best chocolate chip cookies ever!); for the impromptu education about monk seals and the philosophical discussion on fidget spinners.

It’s been a truly unforgettable experience, and I can’t wait to dig into the hard-won data from the WHOTS buoys and share it all with my students.

Did You Know?

Dry land can feel like it’s moving, too! After spending an extended amount of time at sea, your body seems to expect the ground to be rolling underneath your feet, just like the deck of the ship… but nope! Just you! One slang term for this is “dock rock” — and it’s more than a little strange.

The WHOTS-13 buoy after a year at sea. These three red-footed boobies will lose their perch soon!

It’s deja vu all over again! The WHOTS-14 buoy is stable and transmitting data, and all the in situ measurements necessary to verify the accuracy of that data have been taken. Now it’s time to go get the WHOTS-13 buoy, and bring it home.

WHOTS-13 Buoy Diagram

The process of retrieving the WHOTS-13 buoy is essentially the same as deploying the WHOTS-14 buoy — except in reverse, and a lot more slimy. Take a look at the diagram of the WHOTS-13 buoy (to the left), and you’ll notice that it looks almost identical to the WHOTS-14 buoy. Aside from a few minor changes from year to year, the configuration of the buoys remains essentially the same… so the three and a half miles of stuff that went into the ocean on Thursday? The same amount has all got to come back up.

At 6:38AM HAST, a signal was sent from the ship to the acoustic releases on the WHOTS-13 buoy’s anchor. After a year under three miles of water, the mooring line is on its way back to the surface!

From the time the signal was sent to the acoustic releases on the anchor to last instrument coming back on board, recovering the WHOTS-13 buoy took 9 hours and 53 minutes.

Personal Log:

Now that I have witnessed (and participated in, however briefly) both a buoy deployment and retrieval, one of the things that impressed me the most was how well coordinated everything was, and how smoothly everything went. Both deployment and retrieval were reviewed multiple times, from short overviews at daily briefings (an afternoon meeting involving the ship’s officers, crew and the science team) to extensive hour long “walk throughs” the day before the main event. Consequently, everyone knew exactly what they were supposed to be doing, and where and when they were supposed to be doing it — which lead to minimal discussion, confusion and (I assume) stress. Each operation ran like a well choreographed dance; even when something unexpected happened (like the glass ball exploding on deck during deployment of the WHOTS-14 buoy), since everybody knew what the next step was supposed to be, there was always space to pause and work through the problem. Communication is most definitely key!

The other thing that really made an impression was how much emphasis was placed on taking breaks and drinking enough water. It was hot, humid and sunny during both deployment and recovery, and since Hi’ialakai had to be pointed directly into the wind during the operations, there was virtually no wind on the working deck at all. I’ve always thought as the ocean as a place you go to cool off, but, at least for these few days, it’s been anything but! With apologies to Coleridge: “Water, water, everywhere, nor any place to swim!”

A tangled mess of anything can be called a wuzzle. For example: “I don’t know how my headphones got into such a wuzzle.” The mess of glass balls on the deck is most definitely a wuzzle.

Science and Technology Log:

It’s deployment day! After months of preparation and days of practice, this buoy is finally going in the water!

The sheer volume of stuff that’s involved is mind boggling. There’s the buoy itself, which is nearly 3 meters (approximately 9 feet) tall; one meter of that sits below the surface. There’s 16 MicroCats (which are instruments measuring temperature, salinity and depth of the water) attached to over 350 meters of chain and wire. Then there’s another 1,800 meters of wire and 3,600 meters of two different types of line (rope) — heavy nylon and polypropylene. Then there’s 68 glass balls, for flotation. After that, there’s another 35 meters of chain and nylon line. Attached to that is an acoustic release, which does exactly what it sounds like it does — if it “hears” a special signal, it detaches from whatever is holding it down. In this case, that’s a 9,300 pound anchor. (The acoustic release and the glass balls make sure that all the instruments on the mooring line can be recovered.) All in all, nearly 6,000 meters — three and a half miles — of equipment and instrumentation is going over the stern of the Hi’ialakai. The length of the mooring line is actually longer (approximately one and a quarter times longer) than the ocean is deep where the buoy is being deployed. This is done so that if (or when) the buoy is pulled by strong winds or currents, there is extra “space” available to keep the buoy from getting pulled under water.

WHOTS-14 mooring diagram.

Take a look at the diagram of the WHOTS-14 buoy. It’s easy to assume that the everything goes into the water in the exact same order as is shown on the diagram — but the reality of deployment is actually very different.

First, the MicroCats that are attached to the first 30 meters of chain (6 of them) go over the side. Approximately the first five meters of chain stay on board, which is then is attached to the buoy. After that, the buoy is hooked up to the crane, and gently lifted off the deck, over the side, and into the water. Then, the remaining ten MicroCats are attached, one by one, to the 325 meters of wire and, one by one, lowered into the water. Then the additional 3,400 meters of wire and nylon line are slowly eased off the ship and into the ocean. After that, the glass balls (two-foot diameter spheres made of heavy glass and covered by bright yellow plastic “hats”) are attached and join the rest of the mooring line in the ocean. Finally, after hours of hard work, the end of the mooring line is attached to the anchor. Then, with a little help from the ship’s crane, the anchor slides off the stern of the ship, thunks into the water, and slowly starts making its way to the bottom.

4:18PM HAST: Splashdown! The anchor is dropped. 

From the morning-of preparations to the anchor sliding off the Hi’ialakai’s stern, deploying the WHOTS buoy took 9 hours and 41 minutes.

My laptop, secured for sea!

Another item to file under Things You Never Think About: Velcro is awesome. Ships — all ships, even one the size of the Hi’ialakai — frequently move in unexpected, jarring ways. (If you’ve never been on a ship at sea, it’s a bit like walking through the “Fun House” at a carnival — one of the ones with the moving floors. You try to put your foot down, the floor drops a few inches underneath you, and you’re suddenly trying to walk on air.) For this reason, it’s important to keep everything as secured as possible. Rope and straps are good for tying down things that can stay in one place, but something like a laptop, which needs to be mobile? Velcro!

Getting ready to attach the glass balls to the mooring line. The light blue Colmega is in the upper right hand corner of the picture, trailing out behind the ship. The buoy, at the end of over three miles of mooring line, is no longer visible.

Not all line is created equal. Aside from obvious differences in the size and color, different lines have different purposes. The heavy nylon line (which is white; see the picture in slideshow of the line being deployed) is actually able to stretch, which is another safety precaution, ensuring that the buoy will not be pulled under water. The light blue polypropylene line, called Colmega, floats. In the picture to the left, you can see a light blue line floating in the water, stretching off into the distance. It’s not floating because it’s attached to the ship — it’s floating all by itself!

Approaching Weather

When an anchor is dropped, forces in the ocean will cause this massive object to drift as it falls.  Last year, after the anchor of mooring 12 was dropped, an acoustic message was sent to the release mechanism on the anchor to locate it.  This was repeated in three locations so that the location of the anchor could be triangulated much like how an earthquake epicenter is found.  This was repeated this year for mooring 13 so next year, they will know where it is.  From where we dropped the anchor to where it fell, was a horizontal distance of 3oo meters.  The ocean moved the 9300 pound anchor 300 meters.  What a force!

The next morning as the ship was in position, another acoustic message was sent that triggered the release of the glass floats from the anchor. Not surprisingly, the floats took nearly an hour to travel up the nearly 3 miles to the surface.

Float recovery

A small boat went to retrieve the mooring attached to the floats

Once the floats were located at the surface, a small boat was deployed to secure the end of the mooring to the Hi’ialakai. The glass floats were loaded onto the ship.  17 floats that had imploded when they were deployed last year.  Listen to imploding floats recorded by the hydrophone.  Implosion.

Next, came the lengthy retrieval of the line (3000+ meters). A capstan to apply force to the line was used as the research associates and team arranged the line in the shipping boxes. The colmega and nylon retrieval lasted about 3 hours.

Bringing up the colmega line.

Bringing up the colmega line and packing it for shipping.

Once the wire portion of the mooring was reached, sensors were removed as they rose and stored. Finally the mooring was released, leaving the buoy with about 40 meters of line with sensors attached and hanging below.

The NOAA officer on the bridge maneuvered the ship close enough to the buoy so that it could be secured to the ship and eventually lifted by the crane and placed on deck. This was followed by the retrieval of the last sensors.

Mooring removal was accomplished in seas with 5-6 feet swells at times. From my vantage point, everything seemed to go well in the recovery process. This is not always the case. Imagine what would happen, if the buoy separated from the rest of the mooring before releasing the floats and the mooring is laying on the sea floor? What would happen if the float release was not triggered and you have a mooring attached to the 8000+ pound anchor?  There are plans for when these events occur.  In both cases, a cable with a hook (or many hooks) is snaked down to try and grab the mooring line and bring it to the surface.

Now that the mooring has been recovered, the science team continues to collect data from the CTD (conductivity/temperature/depth) casts.  By the end of tomorrow, the CTDs would have collected data for approximately 25 hours.  The data from the CTDs will enable the alignment of the two moorings.

The WHOTS (Woods Hole Oceanographic Institution Hawaii Ocean Time Series Site) mooring project is led by is led by two scientists from Woods Hole Oceanographic Institution;  Al Plueddeman and Robert Weller.  Both scientists have been involved with the project since 2004.  Plueddeman led this year’s operations and next year it will be Weller.  Plueddeman recorded detailed notes of the operation that helped me fill in some blanks in my notes.  He answered my questions.  I am thankful to have been included in this project and am grateful for this experience and excited to share with my students back in Eugene, Oregon.

Al Plueddeman

Al Plueddeman, Senior Scientist

The long term observations (air-sea fluxes) collected by the moorings at Station Aloha will be used to better understand climate variability.  WHOTS is funded by NOAA and NSF and is a joint venture with University of Hawaii.  I will definitely be including real time and archived data from WHOTS in Environmental Science.

Personal Log

I have really enjoyed having the opportunity to talk with the crew of the Hi’ialakai.  There were many pathways taken to get to this point of being aboard this ship.  I learned about schools and programs that I had never even heard about.  My students will learn from this adventure of mine, that there are programs that can lead them to successful oceanic careers.

Brian Kibler

Brian Kibler

I sailed with Brian Kibler in 2013 aboard the Oscar Dyson up in the Gulf of Alaska.  He completed a two year program at Seattle Maritime Academy where he became credentialed to be an Able Bodied Seaman.  After a year as an intern aboard the Oscar Dyson, he was hired.  A few years ago he transferred to the Hi’ialakai and has now been with NOAA for 5 years.  On board, he is responsible for rigging, watch and other tasks that arise.  Brian was one of the stars of the video I made called Sharks on Deck. Watch it here.

Tyler Matta

Tyler Matta, 3rd Engineer

Tyler Matta has been sailing with NOAA for nearly a year.  He sought a hands-on engineering program and enrolled at Cal Maritime (Forbes ranked the school high due to the 95% job placement) and earned a degree in maritime engineering and was licensed as an engineer.  After sailing to the South Pacific on a 500 ft ship, he was hooked.  He was hired by NOAA at a job fair as a 3rd engineer and soon will have enough sea days to move to 2nd engineer.

 

 

There are 6 NOAA Corps members on  the Hi’ialakai.  They all went through an approximately 5 month training program at the Coast Guard Academy in New London, CT.  To apply, a candidate should have a 4 year degree in a NOAA related field such as science, math or engineering.  Our commanding officer, Liz Kretovic, attended Massachusetts Maritime Academy and majored in marine safety and environmental protection.  Other officers graduated with degrees in marine science, marine biology, and environmental studies.

ENS Chappelle

NOAA Ensign Nicki Chappelle

Ensign (ENS) Nikki Chappelle is new to the NOAA Corps.  In fact, this is her first cruise aboard the Hi’ialakai and second with NOAA.  She is shadowing ENS Bryan Stephan for on the job training.  She spent most of her schooling just south of where I teach.  I am hoping that when she visits her family in Cottage Grove, Oregon that she might make a stop at my school to talk to my students.  She graduated from Oregon State University with degrees in zoology and communication.  In the past she was a wildfire fighter, a circus worker (caring for the elephants) and a diver at Sea World.

All of the officers have 2 four hour shifts a day on the bridge.  For example ENS Chappelle’s shifts are 8am to 12pm and 8pm to 12am.  The responsibilities of the officers include navigating the ship, recording meteorological information, overseeing safety.  Officers have other tasks to complete when not on the bridge such as correcting navigational maps or safety and damage control. ENS Stephan manages the store on board as a collateral assignment.  After officers finish training they are sent to sea for 2-3 years (usually 2) and then rotate to land for 3 years and then back to sea.  NOAA Officers see the world while at sea as they support ocean and atmospheric science research.

Frank Russo

ET Frank Russo

Electronics technician (ET) seem to be in short supply with NOAA.  There are lots of job opportunities.  According to Larry Wooten (from Newport’s Marine Operation Center of the Pacific), NOAA has hired 7 ETs since November.  Frank Russo III is sailing with NOAA for the first time as an ET.  But this is definitely not his first time at sea.  He spent 24 years in the navy, 10 at Military Sealift Command supporting naval assets and marines around the world.  His responsibilities on the Hi’ialakai include maintaining navigational equipment on the bridge, making sure the radio, radar and NAVTEX (for weather alerts) are functioning properly and maintaining the server so that the scientists have computer access.

I have met so many interesting people on the Hi’ialakai.  I appreciate everyone who took the time to chat with me about their careers or anything else.  I wish I had more time so that I could get to know more of the Hi’ialakai crew.  Thanks.  Special thanks to our XO Amanda Goeller and Senior Scientist Al Plueddeman for reviewing my blog posts.  And for letting me tag along.

 

Did You Know?

The buoy at the top of the mooring becomes a popular hang out for organisms in the area. As we approached mooring 12, there were several red-footed boobies standing their ground. There were also plenty of barnacles and other organisms that are planktonic in some stage of their lives. Fishing line is strung across the center of the buoy to discourage visitors but some still use the buoy as a rest stop. The accumulation of organism that can lead to corrosion and malfunction of the equipment is biofoul.

Science and Technology Log

The Aloha Station is about 100 miles north of Oahu, Hawaii and was selected because of its closeness to port but distance from land influences (temperature, precipitation etc).  The goal is to select a site that represents the north Pacific, where data can be collected on the interactions between the ocean and the atmosphere. Woods Hole Oceanographic Institution Hawaii Ocean Time Series (WHOTS) has used this site for research since 2004.  You can find real time surface and meteorological data and archived data at the WHOTS website.

We are stationed in the vicinity of mooring 12 and 13 in the Aloha Station to begin intercomparison testing.  CTD (conductivity/temperature/depth) casts are conducted on a regular schedule. This data will help align the data from mooring 12 to mooring 13. If CTDs don’t match up between the two moorings then efforts will be made to determine why.

Mooring 13 is being inspected to make sure sensors are working. Photographs have been taken to determine measurement height of the instruments and where the water line is.

When I was aboard the Oscar Dyson, there were multiple studies going on besides the Walleye Pollock survey. The same is true on the Hi’ialakai. The focus is on the mooring deployment and recovery but there are a professor and graduate student from North Carolina State University who are investigating aerosol fluxes.

Professor Nicholas Meskhidze earned his first Physics degree from Tbilisi State University (Georgia).  He completed his PhD at Georgia Institute of Technology (USA).  He is now an Associate Professor at NC State University Department of Marine Earth and Atmospheric Sciences.

Meskhidze’s study on this cruise is looking at sea spray aerosol abundance in marine boundary layer and quantifying their flux values. Sea spray is formed from breaking waves. Sea spray analysis begins by collecting the aerosol. Using electrical current, particles of a given size (for example 100 nanometer (nm)) are selected for. This size represents the typical size of environmental climatically important particles (70-124 nm). The next step is to remove all other particles typically found in the marine boundary layer, such as ammonium sulfate, black carbon, mineral dust and any organics. The remaining particles are sea salt.

Sea spray analysis

Dr. Nicholas Meskhidze with the sea spray analysis equipment

Meskhidze is looking at the fluxes of the salt aerosols.  Sea salt aerosols are interesting.  If a salt aerosol is placed in 80% humidity, it doubles in size.  But then placed in 90% humidity, it quadruples in size. Due to their unique properties, sea salt aerosols can have considerable effect on atmospheric turbidity and cloud properties.

Aerosols are key components of our climate but little is known about them. Climate models are used to predict future climatic change, but how can one do this without understanding a key component (aerosols)?

Personal Log

The galley (ship’s kitchen) is a happening place three times a day.  The stewards are responsible for feeding 30-40 people.

Chief Steward Gary Allen is permanently assigned to the Hi’ialakai. He has worked for NOAA for 42 years and he has stories to tell. He grew up in Tallahassee, Florida and his early work was at his father’s BBQ stand. He attended Southern University on a football scholarship and majored in food nutrition. After an injury, he finished school at Florida A & M. He worked for a few years in the hotel food industry, working his way up to executive chef. Eventually he was offered the sous chef job at Brennan’s in New Orleans. He turned it down to go to sea.

Chief Steward Allen Gary

Chief Steward Allen Gary

In 1971, he sailed for the first time with NOAA. The chief steward was a very good mentor and Gary decided to make cooking at sea his career. He took a little hiatus but was back with NOAA in 1975, where he would spend 18 years aboard the Discoverer and would become chief steward in 1984. He would sail on several other ships before finding his way to the Hi’ialakai in 2004.

In the 42 years at sea, Gary has seen many changes. Early in his career, he would only be able to call home from ports perhaps every 30 days. Now communication allows us to stay in contact more. He is married to his wife of 43 years and they raised 3 daughters in Seattle.

I asked him what he enjoys the most about being at sea. He has loved seeing new places that others don’t get to see. He has been everywhere, the arctic to Antarctica. He enjoys the serenity of being at sea. He loves cooking for all the great people he meets.

I met Ava Speights aboard the Oscar Dyson in 2013 when she was the chief steward and I was participating in the walleye pollock survey as a Teacher at Sea. She has been with NOAA for 10 years.

Ava Speights (on the right) and me

Ava Speights (on the right) and me

She and a friend decided to become seamen. Ava began working in a shipyard painting ships. In 2007, she became a GVA (general vessel assistant) and was asked to sail to the Bahamas for 2 weeks as the cook. This shifted her career pathway and through NOAA cooking classes and on the job training, she has worked her way up to chief steward.

She is not assigned to a specific ship. She augments, meaning she travels between ships as needed. She works 6 months of the year, which allows her to spend time with her 2 daughters, 1 son, 2 stepdaughters and 4 grandchildren. Her husband is an engineer with NOAA. Her niece is an AB (able bodied seaman) on deck. Her son is a chief cook for Seafarer’s.  And her daughter who just graduated high school will be attending Seafarer’s International Union to become a baker.  Sailing must run in her family.

She loves to cook and understands that food comforts people. She likes providing that comfort.  She has also enjoyed traveling the world from Africa to Belgium.

2nd Cook Nick Anderson

2nd Cook Nick Anderson

Nick is 2nd cook and this is his first cruise with NOAA. He attended cooking school in California and cooked for the Coast Guard for 6 years where he had on the job training. In 2014, he studied at the Culinary Institute of America and from there arrived on the Hi’ialakai. He also is an augmenter, so he travels from ship to ship as Ava does.

 

 

 

Did You Know?

The Hi’ialakai positioned mooring 13 in an area with a 6 mile radius known as the Aloha Station. Check out all of the research that takes place here at Station Aloha. There is a cabled observatory 4800 meters below the ocean surface. A hydrophone picks up on sounds and produces a seismograph. Check the results for the night the anchor was dropped.

The mooring site was chosen because it is far enough away from Hawaii so that it is not influenced by the landmasses. Mooring 13 will be located near mooring 12 in the North Pacific Ocean where the Northeast Trade Winds blow. Data collected from the moorings will be used to better understand the interactions between the atmosphere and the ocean.

There is a lot more going on than just plopping a mooring in the sea. Chief Scientist Al Plueddemann from Woods Hole Oceanographic Institution and his team began in-port prep work on June 16th. This included loading, positioning and securing the scientific equipment on the ship.  A meteorological system needed to be installed on the Hi’ialakai to collect data critical to the mission.  And then there was the assembly of the buoy which had been shipped to Hawaii in pieces.  Once assembled, the sensors on the buoy were tested.

As we left Oahu, we stopped to perform a CTD (conductivity/temperature/depth) cast. This allowed for the testing of the equipment and once water samples were collected, the calibration of the conductivity sensors occurred.

Sunday, June 26th, was the day of deployment. Beginning very early in the morning, equipment was arranged on deck to make deployment efficient as possible. And the science team mentally prepared for the day’s task.

Promptly at 7:30 am, deployment began. The first stage was to deploy the top 47 meters of the mooring with sensing instruments called microcats attached at 5 meter intervals. A microcats has a memory card and will collect temperature, conductivity and pressure data about every three minutes until the mooring is removed next year.

Microcats readied for deployment. They are lined up on the deck based on their deployment depth.

This portion of the mooring is then attached to the surface buoy, which is lifted by a crane and lowered overboard. More of the mooring with instruments is lowered over the stern.

The remainder of the mooring is composed of wire, nylon, 68 glass balls and an anchor.  At one point, the mooring wire became damaged. To solve this problem, marine technicians and crew removed the damaged portions and replaced the section with wire from a new spool. This process delayed the completion of mooring deployment but it showed how problems can be solved even when far out at sea.

After dinner, the nylon section of the rope was deployed. Amazingly, this section is more than 2000 meters long and will be hand deployed followed by a section of 1500 m colmega line. It was dark by the time this portion was in the water. 68 glass floats were then attached and moved into the water. These floats will help in the recovery of the mooring next year. The attachment to the anchor was readied.

These glass floats will help when the mooring is recovered next year.

The anchor weighs 9300 pounds on deck and will sit at a depth of 4756 meters. That is nearly 3 miles below the ocean surface. The crane is used to lift the anchor overboard. The anchor will drop at 1.6 m/s and may take about 50 minutes to reach the bottom.  As the anchor sinks, the wire, nylon and the rest of the mooring will be pulled down. Once it reaches the bottom, the mooring will be roughly vertical from the buoy to the anchor.

Personal Log

I sailed aboard NOAA ship Oscar Dyson in 2013 so I already had a general idea of what life aboard a ship would be. Both ships have workout areas, laundry facilities, lounges, and of course messes where we all eat. But on the Hi’ialakai, I am less likely to get lost because of the layout. A door that goes up is near a door that goes down.

On our first day aboard, we held two safety drills. The first was the abandon ship drill. As soon as we heard 6 short and 1 long whistles, we grabbed our life jacket, survival suit and a hat. We reported to our muster stations. I am assigned to lifeboat #1 and I report the starboard side of 0-3 deck ( 2 levels up from my room). Once I arrived, a NOAA officer began taking role and told us to don the survival suit. This being my first time putting the suit on, I was excited. But that didn’t last long. Getting the legs on after taking off shoes was easy as was putting one arm in. After that, it was challenging. It was about 84 F outside. The suit is made of neoprene. And my hands were the shapes of mittens so imagine trying to zip it up. I finally was successful and suffered a bit to get a few photos. This was followed by a lesson for how to release the lifeboats. There are enough lifeboats on each side of the ship, to hold 150% of the capacity on board.

Safety is an important aspect of living aboard a NOAA ship. It is critical to practice drills just like we do at school. So when something does happen, everyone knows what to do. A long whistle signals a fire. All of the scientists report to the Dry Lab for a head count and to wait for further instruction.

I am reminded of how small our world really is.  At dinner Saturday, I discovered one of the new NOAA officers was from Cottage Grove, Oregon. Cottage Grove is just a short drive south of Eugene. She had a friend of mine as her calculus teacher.  Then a research associate asked me if I knew a kid, who had graduated from South Eugene High School and swam in Virginia. I did. He had not only been in my class but also swam with my oldest son on a number of relay teams growing up. Small world indeed.

 

Did You Know?

The Hi’ialakai was once a Navy surveillance ship (USNS Vindicator) during the Cold War. NOAA acquired it in 2001 and converted it to support oceanic research.

My name is Julia Harvey and I currently teach biology and environmental science at South Eugene High School in Eugene, Oregon. Next year I will also be teaching AP Biology. I have been teaching for 25 years beginning on the island of Vava’u in the Kingdom of Tonga. Some of my students have now become science teachers.

Early interest in marine sciences.

Eugene is at the southern end of the Willamette Valley and just about an hour away from the Pacific Ocean. In the valley, we are closely connected to the Pacific Ocean. The salmon that swim up our McKenzie River have made their way from the Pacific. Our wet and rainy climate is the result of weather patterns that originate off shore. And when it gets to hot in the valley, we head over to cool off on the beaches of the Pacific.

In 2013, I sailed aboard the Oscar Dyson on the Gulf of Alaska out of Kodiak. I was part of the third leg of the Pollock fish survey. Pollock is the fish used to make fish sticks and imitation crab. I didn’t know until this cruise, that the Pollock fishery is the one of the largest fisheries in the world. And I had never even heard of a Pollock until I was going to be sailing on the Oscar Dyson. I worked with amazing scientists on board who kindly helped me learn the process for finding schools of fish in the water using acoustics and then how to process the catch in order to provide information about the health of the fishery.

There were other studies going on the Oscar Dyson.  One involved surveying the ocean bottom and another involved counting  krill.

I leave aboard the Hi’ialakai (easy to say after learning Tongan) in a few days. We will be at sea for 9 days, north of Hawaii.   The Chief Scientist is affiliated with Woods Hole Oceanographic Institute and other scientists are from University of Hawaii, NOAA Earth System Research Laboratory, and North Carolina State University. The main purpose of the study is to recover and deploy WHOTS moorings while collecting CTD (conductivity/temperature/depth) casts and data from shipboard sensors. I am especially interested to learn more about the sea spray analysis and how it relates to climatic effects.

This will be my first physical oceanography cruise. All of the studies I did aboard the Vantuna at Occidental College were biological as was the work done on the Oscar Dyson. I am excited to take my learning in a different direction.

I found it more difficult to pack for the cruise out of Hawaii then out of Alaska. This time, there is a larger range of weather that could be expected. Beginning on Oahu (shorts and tank tops) to the open ocean (steel toe boots and layers of clothes). But there are a few items that are making the trip with me again. I could not leave the Go Pro behind. I captured Dall porpoises bow surfing in 2013 as well as the processing of thousands of fish. And of course I have the anti-seasickness medication. It was wonderful to feel good the whole cruise last time. I will not be streaming videos but I will be entertained with a few books I packed.

I will be blogging several times while I am at sea and I hope you will continue to follow my journey at sea.
