Science and Technology Log:

When attempting something for the last time, it can be nice to end on a high note, or in other words, to go out with a bang.  Our last CPS, coastal pelagic species, haul of this mission was a high note.  Not only did we catch almost exclusively our target, but the speed and efficiency with which we processed the catch was the finest of this mission.  While we were in the middle of processing, it struck me how we knew our roles and communication was no longer about how and what to do, but was clear and concise.  It was a team communicating to get a job done. 

I especially felt much more confident and helpful.  I was able to sort the catch, collect and enter the data, collect the otoliths, and assist in the clean up.  I am still not as fast as my far more experienced teammates on this excursion at collecting the otoliths, but I think they were surprised at how much quicker I was this time. 

Mostly today we caught jack mackerel.  We had so many that we needed to use the hopper and the conveyor belt to make the processing go more quickly.  This was the first time that we needed to use it on this trip.  It was fun to see how excited everyone was.

I also had the opportunity to deploy a second drifter buoy during this mission.  The last one was deployed during the night, but this one was during the day.  This one was marked with a special message, “GO PACK GO!”, as well as the names of my students and my children.  I cannot wait to see where they go and how long they are at sea.  According to the global drifter array, the closest one right now is from South Korea and has been in the water over 1400 days!  I hope this one can match that.  If you or someone you know would be interested in participating in the Adopt a Drifter program, you can find more information on how to participate by clicking the link.  

The end of this mission is here and my work is finished.  There is much work ahead still for many of the scientists on board with me using the data we collected while at sea.  Analyzing the data plays a huge part in helping to make informed decisions about commercial fishing and keeping the pacific CPS populations healthy.  

Personal Log:

In The Return of the King, J.R.R. Tolkien wrote, “Well, here at last, dear friends, on the shores of the sea comes the end of our fellowship.”  Often it can be bittersweet when a chapter in your life comes to an end.  This is a small part of my life but an experience that will stay with me for a lifetime.  I am saddened to see it come to an end, and I am eager to get back home too.  I learned a lot and I met great people.  I think what I will miss the most is learning about so many new creatures and being in one place with so many experts in their fields.  I will definitely not miss fighting sea sickness though. 

This was a terrific program and I am honored that I had the opportunity to participate in the Teacher at Sea program.  I started this project looking for a new adventure to bring back into my classroom and to try to inspire my students to go out and do new and exciting things for themselves.  I feel that with the friendships I have made and the knowledge I have gained I am ready to enhance my lessons for my students for years to come.

Did You Know?

There are more than 33,000 different types of fish species.  That is greater than all of the other vertebrate species (mammals, birds, amphibians, and reptiles) combined, and there are likely more fish still to be discovered.  

Can you identify this species?

*Hint – I am holding one in the picture above.  It’s a Jack Mackerel.  Jack mackerels are the biggest of the CPS that we are looking for on the West Coast Pelagics Survey.  You can identify them by their dark blue-green coloration on top and their silver below.

Science and Technology Log

Today I had the opportunity to participate in science in a new way than I have before on this mission.  I was able to deploy a drifter as a part of the NOAA Adopt-a-Drifter Program.  A drifter is a tool that NOAA uses to acquire data from all over the ocean to aid with weather forecasting. 

According to NOAA’s Atlantic Oceanographic and Meteorology Laboratory,

“The modern drifter is a high-tech version of the “message in a bottle.” It consists of a surface float and a drogue (sea anchor), which are connected by a long tether. Drifters average their data over a window (typically 90 seconds), and transmit ocean data to an orbiting satellite. Each drifter transmitter is assigned a unique code, referred to as the drifter ID, which makes the identification of each drifter possible.” 

Josh, wearing a life vest and hard hat, holds the drifter (buoy plus folded up drogue) near the railing, ready to deploy. He smiles for the photo. it is nighttime.
Ready to deploy the drifter. If you look closely, it’s labeled with my school’s name: River Trail School of Agricultural Science.

The drifters collect data on ocean surface temperature, wind speed and direction, salinity and barometric pressure. 

The Adopt-a-Drifter Program offers schools, scientists, and other interested parties the opportunity to follow a specific drifter’s trajectory and sea surface conditions.  While there are many schools that participate in the program, there are not many teachers that have the unique opportunity to deploy the drifter themselves.  It is a lot of fun for students to follow along with their drifter, but having deployed the drifters myself will make it even more exciting for my students. 

There is an expression that applies to how I like to teach and to how I will incorporate this experience into my classroom that goes, “Tell me and I may forget.  Show me, and I might remember.  Involve me, and I’ll learn.”  Bringing this experience into my class and having the students follow along as the drifter does its job will provide a learning opportunity that will stick with them for years to come as well as foster a love for science that may inspire them for a lifetime. 

Deploying the drifter

Earlier today I also had the opportunity to help collect water from different depths to get eDNA (Environmental DNA).  We used a CTD rosette (Conductivity, Temperature, and Depth) to take samples of water from various depths of the water column.  Each of the tubes is open when it is dropped in the water.  Then when it reaches the desired depth, a button is pushed to trigger magnets to shut the tube.  This can be done individually for up to twelve tubes on the rosette.  When it is brought to the surface the water can be collected and analyzed.  We took 2.5 liters of water from each sample and ran them individually through a special filter that collected the DNA from the water.  I think collecting eDNA is genius.  Fish leave all sorts of DNA in the water.  By taking the DNA out of the water, it is possible to tell what types of fish were in the various depths of the samples taken even though we did not see or catch them.  It reminds me of a detective searching for clues.  

We also had a haul of hake fish with a few rockfish mixed in.  We even got some lampreys.  In many people’s opinion, hake are not the most beautiful fish, but they are very important.  We eat hake in imitation crab, fish sandwiches, and fish patties.  It is also used in some cat foods.  It is important that we have good data about hake populations to keep them healthy and bountiful.   We separate the fish into different groups, identify what they are, weigh and measure the catch, and record the data.  We have computer programs to enter the data.  There are a number of procedures we have to follow to record the data properly.  Once you have the hang of it, the processing can move pretty quickly.   

Personal Log

I am off the dock and officially back at sea again.  In a way, I am a Teacher at Sea twice. 🙂  My body definitely adjusted much more quickly this time around.  Just as I suspected, everyone is eager to get going.  The hauls are coming in and business has picked up.  Even though the processing of each haul is moving efficiently, extracting the otoliths takes a developed feel.  I’m getting there, but don’t quite have the hang of it yet.  My hands are definitely starting to smell a little fishy no matter how many times I wash them. 

Everyone has been very helpful, and I am learning a lot of new things.  It feels a little weird though, because while it seems like we are just getting started, the finish line is just around the corner.  We return to Newport on the 23rd.  I’ve already done my last load of laundry onboard.  The last few dirty things I’ll do at home. I hope the person who sits next to me on the plane doesn’t mind a faint smell of fish though, because I’m not sure it’s fully coming off for a little while. 

Even though we still have two full days of science work to be done, I have started reflecting a little on everything that has transpired on this mission.  I think the key takeaway so far has been to be flexible and stay ready.  We have plans in life, but they do not always happen how we expect them to go.  You have to be able to adapt and keep a positive attitude to make the most out of whatever opportunity you have. 

I played a lot of sports growing up.  One thing I could not control is playing time.  I learned though, that while you may not always get as much playing time as you think you deserve, you just have to make the most out of the opportunities you do have.  For example if you are only put in for five plays in a particular game, during those five plays you can still be the best player on the field.  No matter what you do, give glory by giving your best.  Vince Lombardi once said, “The quality of a person’s life is in direct proportion to their commitment to excellence, regardless of their chosen field of endeavor.” 

I wonder how the mission would have been different without the obstacles we had to overcome.  Who knows?  But in the end, the what ifs don’t really matter.  With the opportunities we’ve had, we’ve gotten a lot done and made great experiences.  While we’ve been busy, last night and this morning I had a chance to see the stars at night and the sunrise in the morning.  I couldn’t help but  feel reminded of Psalm 19.  I know a lot can happen in the final two-plus days, so I shouldn’t close the book quite yet.  I am excited to see what is still to come as we get to the end of the mission. 

Did You Know?

During the daytime many CPS (coastal pelagic species) fish swim about on their own in search of food, but at night they tend to school together for defense.

Can you identify this specices?

If you guessed Pacific Hake also known as Pacific Whiting, way to go! Some key identifiers are the hake’s round body and silvery color with black speckles on their back. Their average size is up to 3 feet in length.

Today we are heading back out to sea., emphasis on back. We had to make a brief stop back in Newport due to a malfunction with the fog horn.  Since it had been very foggy, it was not safe.  We had to wait in Newport for maintenance.

Therefore, we have not been doing any fishing since my last post.  However, now that it has been repaired we are on our way again.  It will take about 15 hours until we are back at the transects that we need to survey.  We are all very excited to begin fishing again.  In the meantime, in order to learn more about what it takes to be a full time NOAA scientist, I thought it would be a good idea to interview one of the scientists working with me on NOAA Ship Bell M. Shimada about his role on this mission.  

Meet Gary Longo – Research Scientist 2 NOAA Southwest:

Gary Longo in Newport.
  1. Why is your work important?  

My work is important because it helps inform management and stock assessors of population structure within federally managed fisheries, because understanding population structure is critical to effective management.

  1. What do you enjoy most about your work?

My favorite part of my job is getting to the point that you see results from data analysis, because often to get to that point it involves time in the field, collecting samples, extracting DNA in the lab, and preparing libraries for sequencing, analyzing the data, and finally starting to see the picture with the results of all your hard work.

  1. Where do you do most of your work?

Most of my work is done at the Southwest Fisheries Center in La Jolla, California.  However the species: pacific sardine, northern anchovy, lingcod, and various rock fish species, that I focus on in my work are generally distributed in the northeast Pacific.

  1. What tool do you use in your work that you could not live without?

My computer, for running analysis and writing up results.

  1. If you could invent any tool to make your work more efficient and cost was no object, what would it be and why?

An autonomous vehicle that hunted fishes and was non lethal but took tissue samples and sequenced each sample’s genome.

  1. When did you know you wanted to pursue a career in science or an ocean career?

When I was at the Monterey Bay Aquarium I realized that my heart wasn’t into medicine, which I was studying at the time.  I was a member at the aquarium and went there all the time and I thought this is what I want to do.

  1. What part of your job with NOAA did you least expect to be doing?

Extra paperwork. 

  1. How do you help wider audiences to understand and appreciate NOAA science?

I try to explain things that I would want my grandmother to understand.  Generally speaking when I am on hikes or birding I speak with curious people and try to engage with them.

  1. How did you become interested in communicating about science?

I became interested when I became a teacher’s assistant in grad school and an instructor in ichthyology at UC Santa Cruz.

  1. What’s at the top of your recommended reading list for a young person exploring ocean or science career options?

One of my favorites is Song of the Dodo by David Quamman.  That’s a great book about island biogeography and the importance of habitat connectivity

  1. What do you think you would be doing if you were not working for NOAA?

Using my dive masters to share my passion of diving with interested folks.

  1. Do you have any outside hobbies?

I enjoy surfing, birding, hiking, and scuba diving.

Gary and the other scientists working on board NOAA Ship Bell M. Shimada have been amazing.  They are all very passionate about their work, and very knowledgeable about everything we are studying on this mission.  It is inspiring to work with people who care so much about their work.

Personal Log

Maybe some of you have heard the expression, “Hurry up and wait.”  I have heard that off and on at various times throughout my life.  This part of our mission has seemed to embody the sentiment behind the expression like few other times I have experienced. 

Getting ready for this mission seemed like a whirlwind with balancing my life at home with my family and trying to prepare mentally and physically for my time on NOAA Ship Bell M. Shimada.  Once I was in Newport things slowed down a little while adjusting to life onboard and making our way out to our first transect.  Then business really picked up and everything was full of excitement and energy.  Processing our first catch was a time filled with enough adrenaline to make all of us forget that it was one in the morning. 

Then when the fog horn went out of commission everything came to a proverbial screeching halt.  Hurry up, now wait.  The initial feelings of frustration, restlessness, and even anxiety were pervasive.  There were even temptations to gripe and have a “woe is me” type of attitude.  Unfortunately, in life sometimes we have to deal with setbacks due to circumstances that are beyond our control.

I work through tough or frustrating situations in life by taking a step back to gain some perspective, and remembering that there are things outside of my life that are bigger and more important.  My hope is built on nothing less.  All other ground is sinking sand.  When I put my life in a better perspective, I know there will be brighter days, and the things that were bothering me no longer seem so pressing. 

Heading out to sea again has reinvigorated everyone onboard.  We are chomping at the bit, and I think we are just going to rip it.  Pull back and let the big dog eat.  There is an excitement that is palpable.  Being with people who care deeply about their work is a blessing.  I want to take back as much as I can from this experience to my classroom for my students, but I want to remember that desire to do my work and do it well most of all.  Hopefully, very soon we will be so busy processing catches and recording data that I will be nearly too tired to write, but when I do I’m sure I’ll have lots to say.  Let’s hurry up!

Did You Know?

An otolith is a small structure found inside fish which helps them detect sound and keep their balance.  Otoliths grow inside fish throughout their life and can be used to determine their age, almost like a tree, by counting the growth rings.  Pretty cool!

Can you identify this species?

Mola Mola, aka. Ocean Sunfish

In my opinion, one of the coolest fish names, mola mola.  They are also referred to as an ocean sunfish.  Mola mola have a jellyfish based diet and can grow to be very large, on average 2200 pounds and six to seven feet wide.  I spotted this one from the flying bridge on our way back to Newport.  I speculate it was a little more than half those sizes.

Science and Technology Log

While I was sleeping, the net that we helped set out was brought back in with a haul of hake.  Exactly what the morning crew was looking for!  It was almost entirely hake, which made the processing extremely straight forward.  Some might be inclined to think that this is exactly what science is supposed to look like. 

Fast forward to my shift again and shortly after we woke up, there was a haul that was ready to be brought in.  We were all very excited for our first chance to process a catch.  Well, this time when the net was brought up, it was awfully full.  We were excited about the possibility of going through the catch and finding our target CPS, Coastal Pelagic Species.  However, it was almost entirely full of krill, and did not have a single specimen of what we were looking for.  Now, some might think that this means our haul was a failure and/or it was bad science.

Those people would be wrong. While the first two hauls of this leg of the survey are diametrically different, they are both good.  Science requires good data.  Data is good when it is reliably accurate.  It doesn’t matter if it is larger numbers or zeros.  So, in our case, while we didn’t get the information we were looking for, we now know that what we did had a result of zero for our targeted CPS .  We also know that where we fished resulted in a catch of krill.  This is knowledge that we can use next time to help us get what we are after.  

In the second catch we did get a few different species.  We caught: North Pacific krill, moon jellyfish, and a handful of eulachon. The eulachon were all weighed and measured for length.  

Personal Log

Today is my brother’s birthday.  Happy birthday!  I am feeling much better.  I continue to take the sea sickness prevention medicine, but I think I have found my sea legs.  I am starting to feel like I know my way around NOAA Ship Shimada more and more, or at least the places I am supposed to go. 🙂 I was happy to make it from my bunk, down past the wet lab and acoustics lab, through the hall, past the mess, down some steps, through a room I never need to stop at, and to the laundry on my very first try!  Our ship even has two places to work out.  I am not brave enough to try a treadmill when the boat is rocking, but I did take an opportunity to do some jump rope. 

I am amazed by the engineers who think through everything that needs to be done to make a ship like ours work.  It is a maze of rooms, cords, and more, but all of it is well thought out and has a purpose. 

I was a little disappointed today.  We had a little extra time in between work during my shift so I went out to check on the stars, but it was foggy out so I could only see a few feet away.  But I am learning a lot and having a ton of fun.  It will be interesting to see what it will be like when we are getting more and larger hauls in a single shift. 

Also, it’s a big deal back in Milwaukee, but the Brewers have won 11 games in a row.  One more tonight means free burgers in the city!  When I spoke with my wife and kids, they were definitely hoping for a win tonight.  Let’s go Brew Crew!

Did You Know?

The eulachon is also known as the candle fish.  It got the name from the fact that it is so oily that if you dry the fish out, you can light the tail on fire and it will burn like a candle.  In the past, the eulachon was prized for its oil.  The oil will even be solid at room temperature, similar to butter.

Can you identify this species?

Science and Technology Log 

An often paraphrased quote by Robert Burns goes, “The best laid plans of mice and men often go awry.”  Well, maybe that phrase also applies to fish. 

The original plans for this leg of the survey were to head out to sea on August 8th.  However, a winch on NOAA Ship Bell M. Shimada stopped working before we took off.  The winch is important as it helps to bring in the net which we need to catch the fish.  It was a two day repair. 

Then on the 10th we were all aboard and ready to leave when the wind decided to kick up.  It was coming in at such an angle and strength that we did not have enough power to push away from the dock safely.  So, we stayed in port for another night. We made the most of it by walking to the Oregon Coast Aquarium.  It was amazing to be with the scientists as we walked through the exhibits.  They have so much knowledge and experience working with the creatures on display. 

Thankfully, the next day, the wind cooperated, and right around 14:50 on August 11th, we were able to set off.  There were cheers and fist pumps as we began our journey. 

In our mission we are taking a survey of the West Coast Pelagics, but specifically we are looking for five main fish: Pacific sardine, jack mackerel, northern anchovy, Pacific mackerel, and Pacific hake.  I will be focusing on CPS, Coastal Pelagic Species, which are the sardines, anchovies, and both mackerels.  Those will be caught during the night time shift that I will be working, midnight to noon.  The reason we catch them at night is that during the day they are spread out and feeding, but at night they come back together for safety. 

This is important work because with the data we collect we will know more about the population, size, and location of the populations and that provides guidance on what should be done for commercial fishing of those populations.  One way we are able to be more efficient in catching the fish is by using certain tools to help us know where the fish are.  We use acoustics technology to determine where, how many, and what kind of fish. 

Today I helped get a TDR, Temperature Depth Recorder, ready to attach to the net.  This sends information back to the ship about the depth of the net and the temperature of the water.  The information when combined with what we know from the acoustics helps us catch what we are after.

Personal Log

Once again following the theme of the day, adaptation has been key.  I knew my schedule going into this adventure was going to require me to change my sleep schedule.  Once the departure date was thrown back three days, there was also no way for me to keep the midnight to noon schedule.  So, I am back today trying to adjust. 

I am also trying to adapt to the motion of the sea.  I brought sea sickness medicine and have been taking it regularly as prescribed, but I am still feeling the effects of the motion a little bit.  One good trick has been getting outside and looking at the horizon.  That has helped quite a bit.  I also enjoy being in the wet lab.  It is a bigger space and that is helping me fight back the queasy feeling. 

The food onboard has been terrific.  I am eating well.  Our main steward’s name is Phil.  He makes some amazing food.  That is one thing I have not had to adjust to in any way. 

I have the internet and am able to make Wi-Fi calls.  Back home there was a flash flood.  A lot of friends and family are dealing with the loss of their things.  Thankfully, I have not heard any reports of people having been hurt.  It is tough to be away from friends and family.  Thankfully, everyone on board has been really nice.  It makes a tough situation easier when you have friends to talk with.  I am looking forward to not feeling sea sick soon and having amazing learning experiences in the days and weeks ahead.

Did You Know?

Greenwich Mean Time is the local time at the Royal Observatory in Greenwhich, England where the Prime Meridian was established in 1884.  It is used as a reference point for telling time all around the world.  On the ship it can be difficult to keep track of time.  The GMT is a way for all of us who come from different time zones and are on different schedules to keep track of what time things are happening.  

Can you identify this species?
