Science and Technology Log

As I adjust back to being awake during the day, and catch up with all the things at home, I still am in disbelief that I had such an incredible opportunity this summer aboard NOAA Ship Reuben Lasker. Sifting through all the different species that we pulled up in our trawls, exploring  the systems that make the ship run, and adjusting to life on a scientific vessel made every day a new adventure. But what really made the trip memorable were the people that I had the chance to talk with during meals, up on the bridge, or in the science labs.  I wanted to share a little about what brought them to NOAA and what advice they have for anyone interested in a life on the sea.

1. Melissa Liotta 

Job/Role: What is your role aboard the ship?

I serve as a fish biologist and survey coordinator for the Integrated West Coast Pelagic Survey. In this capacity, I represent the Northwest and Southwest Fisheries Science Centers, though my home base is at the Southwest center. My responsibilities involve extensive logistical planning and preparation before we ever set sail. I coordinate with teams across both centers and work closely with the ship’s crew to ensure every component of the fisheries survey is ready for operation.

Career Path: How did you get into this career?

I hold a PhD in ecology and evolutionary biology, with a doctoral focus on the mating behaviors of freshwater fish in Mexicoโ€”specifically the highback pygmy swordtail. While that wasn’t marine-focused, teaching ichthyology helped me build a broad foundation of fish knowledge. After graduate school, I felt a calling toward public service and applied science. I began with part-time GIS work for California Fish and Wildlife, then moved into Clean Water Act restoration plans as an environmental scientist for the Regional Water Quality Control Board. When a fish biologist position opened at the NOAA science center in San Diego, I jumped at the chance to return to fish-centric research.

Student Advice: What advice would you give a high school student considering this type of work?

Do not hesitate to accept entry-level roles or part-time opportunities; the path to your dream career often requires persistence and “grinding” through various positions first. Be open to relocating and seek out volunteer opportunities early on. Whether your interest lies in freshwater, marine life, or even plants, the skills you learn in a science labโ€”like those for undergraduatesโ€”are incredibly transferable. You are training to be a scientist first. Explore diverse fields like plant taxonomy or invertebrate studies; you might discover a passion in an area you never expected. Even if it isn’t dolphins, every bit of field experience counts.

2. Brad Erisman

Job/Role: What is your role aboard the ship?

While I participate as a member of the trawl team during our time at sea, my primary responsibility involves leading the biosampling component of the entire survey. I oversee the design, execution, and comprehensive analysis of all biological data collected from our trawls, as well as managing the specialized staff dedicated to this process.

Career Path: How did you get into this career?

My journey began with a fundamental passion for science and the sea. Inspiring high school teachers encouraged me to pursue marine biology in college, where exceptional professors further ignited my interest in fish biology. This led me to graduate school, where I focused on fish behavior and ecology. This research naturally intersected with fisheries, driving my interest in understanding how to better manage and conserve various species. After spending time as a university professor and researcher, I realized I wanted a more direct hand in active resource management, which prompted my recent transition to NOAA.

Student Advice: What advice would you give a high school student considering this type of work?

The field of fisheries and marine biology is incredibly vast and can often feel overwhelming. My best advice is to identify your specific interests as early as possible to carve out a clear career track. Because this work often combines with other disciplinesโ€”such as economics, conservation, or businessโ€”finding that unique combination of what you love will help you navigate the path forward. Discovering your niche early on is the key to maintaining momentum and finding success in this broad scientific landscape.

Chief Scientist Kevin Stierhoff

3. Kevin Stierhoff

Job/Role: What is your role aboard the ship?

For this third leg of the journey, I am serving as the chief scientist. Beyond that, I am the principal investigator for our science center, managing the survey’s broader execution. As chief scientist, I act as the primary liaison between the scientific team and the ship’s command and crew. My focus is ensuring we meet our data collection goals with the highest level of quality while navigating the daily logistics and troubleshooting any hurdles that arise. I also handle communications with our shore-based teams and take the lead on the subsequent reporting and data analysis once we return.

Career Path: How did you get into this career?

My path began with an undergraduate degree in marine biology, but it was a summer internship that truly changed my trajectory. I connected with a professor who opened my eyes to graduate schoolโ€”an option I hadn’t previously considered. I pursued my masterโ€™s and eventually my PhD, followed by research roles and a postdoc. In 2008, I joined NOAA and have spent the years since advancing through various scientific levels, eventually serving as an acting program lead and taking on the leadership responsibilities I hold today. Interestingly, in high school, I was pulled between athletics, science, and the arts; I even considered art school or becoming a veterinarian before the right collegiate program in marine biology caught my eye.

Student Advice: What advice would you give a high school student considering this type of work?

Avoid specializing too early; instead, build a rock-solid foundation in the core sciences like math, chemistry, and physics. Those fundamentals are the building blocks for any specialized field in marine or ocean research. Practical experience is just as vital, so pursue internships early to learn what you truly enjoy. I never set out in high school to become a fisheries biologist with a PhD, but by being flexible and embracing opportunities as they appeared, I found a career that fits. Don’t feel like you must have every step mapped out; sometimes, the best path is the one you remain open enough to discover along the way.

Ensign Camille Cubรฉ

4. Camille Cubรฉ

Job/Role: What is your role aboard the ship?

I am Ensign Camille Cubรฉ, serving as a junior officer. My primary responsibility involves navigating and driving the ship for eight hours each day, while my remaining time is dedicated to various secondary duties. I serve as the medical officer, managing hospital administration and responding to any health emergencies. Additionally, I act as the navigation officerโ€”a role I share with my colleague Kaleenaโ€”where we coordinate with the science team to program research stations into our electronic chart systems and provide navigational briefings to the other officers. Until very recently, I also managed damage control and fire drills.

Student Advice: What advice would you give a high school student considering this type of work?

I highly recommend reaching out to a recruiter or researching the career through YouTube to see if it resonates with you. If possible, request a ship tour; I toured NOAA Ship Bell M. Shimada before applying, and seeing the environment firsthand was what truly convinced me to join. You do not need prior sea-going experience, but you must possess a sense of adventure and the flexibility to handle a nomadic lifestyle and a changing schedule. Beyond navigation, I have received advanced training in diving, small boat handling, and even a medical crash course where I learned to administer IVs and stitches. Academically, you will need a bachelor’s degree. While it doesn’t have to be a specific science, technology, engineering, or math (STEM) degreeโ€”my background is in environmental scienceโ€”you do need core STEM credits in subjects like calculus and chemistry to effectively communicate between the scientific and operational sides of the ship.

What is your favorite part about your job?

My favorite moments occur when I am struck by the sheer beauty of our surroundings, like a spectacular sunrise or a massive pod of dolphins appearing alongside the ship. It reminds me how fortunate I am to be in the middle of the ocean doing this work. I also deeply value the close-knit community and the friendships I have built with the crew. From a professional standpoint, the structured promotion scale provides excellent job security. Since I have a personal passion for fish, I specifically chose a fisheries vessel because I love seeing the tangible, physical results of the scientific data we collect.

What do you think the most challenging thing in your job is?

The most difficult aspect is undoubtedly the time spent away from home, which can exceed 200 days a year. It is a demanding schedule, so we prioritize shipboard morale through social activities like the Mario Kart tournaments we had this week.  Fortunately, the commitment is balanced; after two years of sea duty, officers transition to a three-year land assignment, then repeat. I quite like the fact that I will hold many different jobs in my career, get to learn new things, and live in different places.

5. Michael Fuller

Job/Role: What is your role aboard the ship?

I am Lieutenant Commander Mike Fuller, and I serve as one of the operations officers aboard this vessel. I am responsible for coordinating projects with our scientific partners, managing port logistics for the ship, and mentoring new officers as they come aboard.

Career Path: How did you get into this career?

My journey began during my undergraduate studies at the University of Miami. Our marine science campus was situated directly across from several NOAA laboratories, which piqued my interest. At the time, I was weighing several options for my futureโ€”graduate school, a gap year, or even joining the military to follow my family’s history of service. The turning point came when I met a NOAA officer on his first shore rotation. He had previously sailed with one of my roommates on a research mission and began joining us for football games and social events. He recognized my passion for marine science and my desire to serve, suggesting the NOAA Corps as a perfect marriage of both worlds. He was right; I applied and discovered it was exactly the combination I was looking for. In a full-circle moment, ten years later, that same officer is set to become the next Commanding Officer of this very ship.

Student Advice: What advice would you give a high school student considering this type of work?

There are countless ways to pursue a life at sea, whether through the NOAA Corps and military, the merchant mariner path, or as a research scientist. If you feel drawn to the ocean, the maritime industry offers incredible opportunities in both the public and private sectors. My best advice is to look at where your specific interests intersect with the maritime world. For me, it was a love for natural sciences and environmental conservation, making NOAA the perfect fit. If you are inclined toward engineering or navigation, those roles are vital here as well. Keep an open mind; you can start anywhere from tall ships to working on tugboats to build your experience.

If you are specifically interested in wearing a uniform, take time for self-reflection. Service-based work requires a commitment to leading yourself and others, and ensuring your personal values align with the organization’s mission. Each service has a unique cultureโ€”for instance, people join the NOAA Corps because they specifically want to fulfill that unique mission of science and service. Focus on what brings you fulfillment and whether you are ready to put your ego aside to become part of something larger than yourself. Even if you choose not to join a uniformed service, those leadership qualities remain highly applicable across the maritime industry.

How do I get started?

For those interested in the NOAA Corps, the primary requirement is a solid educational foundation. You specifically need at least 48 STEM semester credit hoursโ€”essentially a STEM minor plus additional coursework. Most people in this field have a background in natural sciences or engineering. If you have a local NOAA lab nearby, I highly recommend volunteering. It is a fantastic way to understand the wide portfolio of work we handle under the Department of Commerce. There are also excellent programs like the undergraduate Hollings Scholarship, which is very prominent at institutions like Oregon State. These programs can pair you with a principal investigator for advanced research opportunities. While high school students can sometimes find ways to volunteer, it becomes much more common in college. Getting out on a research vesselโ€”whether it is a NOAA ship or a university vesselโ€”will tell you very quickly if this lifestyle is right for you. If it is, dive in: explore USA Jobs, look into Pathways internships, or visit the OMAO website to start your application.

Ultimately, identify your passion first. NOAA covers such a vast range of interests that you will likely find a niche that fits. Once you find that spark, be proactive in seeking out these programs and connecting with people already doing the work. There is a constant need for driven individuals who are ready to make the mission happen.

Ship Engineer Allie Kemskey

6. Allie Kempski

Job/Role: What is your role aboard the ship?

My name is Allie Kempski, and I serve as the third assistant engineer. I have been with this vessel for approximately four months, though my tenure with NOAA spans two years. In my current capacity, I hold a United States Coast Guard engineer license, which authorizes me to stand watch and manage operations within the ship’s engine room. My daily responsibilities involve a ten-hour shift dedicated to maintaining the complex mechanical systems that keep the vessel operational.

Career Path: How did you get into this career?

While many mariners have dramatic tales of discovering the sea, my path was more of a family tradition. Both of my parents were engineers who graduated from SUNY Maritime College in New York. Naturally, I followed in their footsteps, attending the same institution to earn a Bachelor of Engineering in mechanical engineering. This specialized education is essentially a “fast track” to a professional maritime career; over four years, I completed rigorous academic coursework alongside three summers of sea time aboard a federal training ship, the Empire State VI. This environment is highly regimented and military-style, designed to weed out those who cannot handle the pressure of hands-on technical work and strict discipline.

Student Advice: What advice would you give a high school student considering this type of work?

I highly recommend investigating the state maritime academies, such as Cal Maritime or SUNY Maritime. If you enjoy hands-on problem-solving rather than sitting at a desk, this is an exceptional field. Don’t let the “engineering” title intimidate you; it is a practical, visual discipline where you learn by taking apart engines and fixing what breaks. Be prepared to work incredibly hard during your college yearsโ€”it is a heavy credit load and a demanding lifestyleโ€”but the payoff is a stable, high-paying career right out of school. You must be comfortable with a nomadic life, as the work often involves being away for months at a time, but the trade-off is significant time off to travel and pursue your own interests.

Career Reflections

What is your favorite part about your job?

The travel opportunities are phenomenal. In my first year with NOAA, I was getting paid to kayak in Glacier Bay National Park and live in historic quarters in Hawaii. It is a thrill to see a massive ship move for the first time and realize you understand the systems making it happen. Beyond the sights, I value the deep friendships formed in tight quarters. This crew becomes your family, and because we have a rotation of two months on and one month off, I have total freedom during my breaks to spend time with my actual family or use my earnings to see the world.

What do you think the most challenging thing in your job is?

The primary challenge is the isolation from home for sixty days at a stretch. Shipboard life means constant proximity to others and very little private space, which isn’t for everyone. The academic path is also grueling; I spent my senior year crying over calculus and license exams while friends at traditional colleges were partying. However, we always say that you work hard at the academy so you can “party later” with a six-figure salary and months of vacation time. It is a high-stakes, high-reward lifestyle that requires resilience and a genuine love for the machinery.

Did you Know?

Cal Poly Maritime Academy is the only Maritime Academy on the West Coast. Enrolling in a maritime academy offers an accelerated path toward a lucrative profession, rewarding students with a Bachelor of Science alongside a prestigious U.S. Coast Guard unlimited licenseโ€”as either a Third Mate or Third Assistant Engineer. These institutions boast exceptional job placement rates, providing graduates with the versatility to pursue careers on the open ocean or within various shoreside management roles. For Oregon students who gain admission to Cal Poly Maritime Academy and choose a path toward a U.S. Coast Guard license, there is an incredible financial opportunity through the Maritime In-State Tuition (MIST) program. This initiative automatically brings the cost of out-of-state tuition down to the California resident rate. This results in an annual tuition of roughly $6,450 plus approximately $1,650 in required campus fees, offering a significant reduction in the typical expenses for non-residents. There are numerous scholarships, as maritime employers are desperate to find qualified candidates. Even if you do not plan on working on a ship, you will be highly qualified for landbased jobs as well. 

If the traditional four-year maritime academy environment isn’t the right fit for your journey, there are several highly viable alternative paths to becoming a merchant mariner. These range from structured, fully-funded apprenticeships to the classic method of working your way up directly on the water. 

 Personal Log

Coming into Newport the last day of the voyage was bittersweet for me. I loved being out on the ocean, but I was excited to see my family again. My sons came to meet me and they watched our ship as it went under the Newport bridge. They werenโ€™t the only ones watching, people were waving and taking pictures, I felt like a celebrity! After we came into port we were waiting for the walkway to be set up, and I was invited to listen in to the officers reviewing how things went coming into Newport. It was a good exercise so that each person could give their feedback to improve the approach in the future, and with all the boat traffic coming into harbor, itโ€™s considered the most stressful time sailing the ship. 

When it was safe to come aboard, NOAA Corps officer Mike Fuller gave my sons a tour of the ship which definitely left an impression on them. Theyโ€™ve been talking about it for days now to everyone we meet. I think they may have some new recruits! 

While Iโ€™d like to extend summer vacation, I am looking forward to talking to students about NOAA and career possibilities. If I were to go back in time, I would definitely consider a maritime career and I want to open that door to the students at Churchill High School. 

A big thank you to the Teacher at Sea program for this wonderful opportunity!

Science and Technology Log

Today we had safety drills, and I felt more confident knowing what to do in an emergency. They also checked fire hoses, and the fire response team practiced suiting up and going to their stations as quickly as possible. We were going to light expired flares into the air, but unfortunately we were unable to do so due to the waves and the acoustic sonar being in the water. 

Stacey, wearing orange overalls and teal latex gloves and holding safety goggles in her left hand, holds up an unlit expired flare in her right hand. she stands on deck in front of piles of nets and the A-frame.

Before I came on board, I was worried that we would have to take โ€œNavyโ€ showers, like my father used to talk about when he was in the service. These are where you only turn on the water to wash away soap and shampoo. Luckily, times have changed and NOAA makes its own water onboard! Here is a photo of one of the evaporators where fresh water is distilled from salt water. They have multiple units, but they usually donโ€™t need to use all of them, unless people take extremely long showers.

Every night, the chief of science, the chief engineer, the operations officer, the commanding officer, all of the deck crew, and the survey lead meet to go over the trawl plan for the night. Based on the days acoustic data, they go over fishing locations, the weather, if any vessels or buoys are in the area, the topography, and if there are any concerns or updates from the crew.

Then they do an operational risk assessment. Each person puts up a finger, with 10 fingers being the highest risk, and zero fingers being no risk. They rate Resources (Boat and Equipment, Supervision, Communication, and Support), Environment (Surf Zone, Remoteness, Ice, Rocks, Traffic, Shallow or Uncharted water), Team Selection (Experience, Training, and Familiarity), Fitness (Physical and Mental), Weather (Effects on mission and safety), and Mission Complexity (New or experimental, or restricts maneuverability). If the total score is high, that can affect whether trawling proceeds or how many trawls will occur that night.

Personal Log

Before I left Eugene to fly to San Francisco, I was excited to start my time with NOAA but also nervous about how well I would adapt and fit in on a research expedition. Admittedly, the fish trawling and sampling is rigorous and switching to a night schedule was tiring for the first few days. But everyone has been so patient and open to all of the questions I have (they even let me steer the ship!), even though I struggle sometimes with understanding some of their answers. Iโ€™ve learned an incredible amount about marine biology, fisheries, and NOAA, along with learning about the people behind the jobs on board.  Now, near the end of my time on board, I feel that I’m more than capable in the wet lab, I’ve adapted to life aboard a ship, and I’m now part of an incredible crew and team. Maybe it’s time I switch to a science teaching position…? ๐Ÿ™‚

My mother just texted me, โ€œSo, what do you do with the fish that you catch?โ€ Great question!

Door used to hold open net

We do three trawls every evening, based on what the acoustic data shows us from moving our ship along our transect lines during the day. We do a marine mammal watch for 15 minutes before we cast the net. If everything is clear, we drop the net into the water. We then put two large metal โ€œdoorsโ€ into the water, that support the mouth of the net opening. The net has been specifically designed for the fish survey, to catch even the smallest fish larva and krill. Towards the end of the net, called the โ€œcodend,โ€ there is a metal grate that is sewn into the net with a slit above it. This grate not only keeps larger species out of the net, like sharks, dolphins, and sea lions, but it  also allows them to escape if they do swim into the net. There are sensors at the top and bottom of the net that show its position so we know that it is in the right position.  Here is a photo of the monitor that can โ€œseeโ€ the net:

This image shows how wide the net is open and its depth

We fish for thirty minutes, and then we hear โ€œhaul back!โ€ which signals the net is being reeled back in. They use a large industrial spool to wind the net and the deck crew makes sure that it doesnโ€™t get tangled, plus they stop if they see anything caught in the lines, such as mola mola (ocean sunfish) that like to hitch a ride in the net.

Stacey, wearing orange rain gear, orange life vest, orange hard hat, and teal gloves, holds up a smaller mola mola in two hands for a photo. she is standing in the wet lab.

When we reach the back of the net, this is where we focus for our survey. If there are any protected species, like salmon, we measure, weigh, and take a quick photo record before we toss them back into the water. We put hardy fish that are not part of our survey into a saltwater bucket and also toss them over the side once we collect data.

We focus mainly on our target species, Northern Anchovies, Pacific Sardines, Pacific Mackerel,  and Jack Mackerel, and separate them out from the rest of the catch. From these, we take a random sample to measure and weigh, and then we remove their otoliths (ear bones) which can be used to determine their age. We document all the species we find, and if there are any sample requests (from universities or marine labs) that we can fulfill, those fish are put into the freezer.

Once we are done sorting, documenting, and data collecting, everything goes back to the sea and we clean up before the next trawl comes in. We always randomly sample five baskets from a catch, no matter how big or small it is. A โ€œwater catchโ€ is if we donโ€™t pull up any of our target species, but weโ€™ve been lucky enough to have at least one in each of our trawls on this leg of the trip. Iโ€™ve been amazed at how different each of our trawls have been, and itโ€™s changed quite a bit as we go north, with different species being more prevalent.

While northern anchovy, Pacific and jack mackerel, whitebait smelt, and Pacific herring make up most of the fish we catch during our survey, California smooth tongue fish are our most common non-target species. Most of our target species are included in federal fisheries management plans, which means scientists regularly monitor their populations to help ensure they are harvested sustainably.

Understanding how fish populations change from year to year is essential for assessing the health of fish stocks and managing fisheries responsibly. Some species are especially important to the West Coast ecosystem and economy. Pacific sardines, for example, once supported a major fishery, but their population has declined dramatically in recent decades. Northern anchovies may not have the same economic value, but they play a critical role in the marine food web by serving as prey for many larger fish, seabirds, and marine mammals. Jack mackerel are also ecologically important and support commercial and bait fisheries that extend from state waters into federally managed waters.

Whitebait smelt and Pacific herring are unique to our survey because they are detected not only in our net catches but also in our acoustic data. Comparing the two datasets helps scientists validate survey results and improve estimates of fish abundance.

Did You Know?

FishBase is a website where you can look up 36500 different fish species, their common names, and pictures to help you identify something that you see or catch. You can even find out what they are called in other countries where they are found, which is tremendously helpful when you are working with fisheries that expand beyond U.S. waters or with migrating fish.

Personal Log

We are now located off of Newport, and I realize we are getting to the end of our trawling survey. I’m excited to get back home and see my family and friends, but I know I’ll miss the adventure of being on a scientific expedition with experts in the field. I love asking questions about the fish we are seeing, the nautical gauges on the bridge, and what all the equipment is down below in the labs and engine room. The wind has died down, and it’s easier walking around the ship. I’m sleeping very well, better than at home, which must be due to the rocking or the physical labor of processing the fish trawling. My favorite activity is mammal watch, making sure none are close to our boat before we put the net into the water. Seeing whales with the moon over the water was a beautiful sight!

Science and Technology Log

To understand more about the acoustic study component of our fish survey, I sat down with Kevin Stierhoff, Chief Scientist and Primary Investigator, and Brad Erisman, marine biologist, to see how our sonar mapping efforts integrate with the nightly trawling operations.

Interview Discussion with Kevin Stierhoff, Chief Scientist:

The Acoustic Trawl Methodology

Kevin: The acoustic trawl method is a globally recognized technique for surveying coastal pelagic species. By utilizing sonar, the ship can efficiently map expansive stretches of the seafloor and record precise echoes from fish populations. These instruments are highly calibrated and sensitive, providing us with accurate data on the biomass below. However, acoustics alone cannot identify the specific species creating the signal. To solve this, we conduct sonar surveys during the day when fish are schooling at depth, and then perform net trawls at night as they rise toward the surface. This nocturnal sampling allows us to determine the species and size composition without the fish avoiding the net as easily. By combining these datasets, we can apply the ratios found in our catches to the sonar echoes gathered during the day. This robust method is the primary tool for managing sardine and anchovy stocks along the West Coast.

Historical Context

While simpler sonar and net surveys were conducted as early as the mid-1970s, the modern integrated approach used by the NOAA Southwest Fisheries Science Center in San Diego began in 2008. Since 2012, we have maintained a consistent schedule, performing these surveys at least once annually.

Observing Ecosystem Shifts

The marine environment has changed significantly since the surveys began. In 2012, sardines were the dominant species, but their numbers plummeted leading to the fishery’s closure in 2015. Conversely, northern anchovy and jack mackerel populations have surged, with anchovies remaining the most prevalent species we encounter today. Sardines have yet to show signs of a rebound following their crash a decade ago.

Environmental Drivers

There is much discussion regarding why these shifts occur. While fishing pressure reduced stocks in the past, current low levels are likely driven by environmental and biological factors, rather than active overfishing.

Leadership Roles at Sea

The structure of the scientific team ensures the integrity of the data collected. The Principal Investigators (PIs) are responsible for the overall coordination and quality of the long-term survey. On the ship, the Chief Scientist manages daily operations and leads the scientific party, coordinating with the PIs to ensure the survey’s objectives are met successfully.

Advanced Sonar Systems

Acoustic sonar system under NOAA Reuben Lasker

The shipโ€™s acoustic “eyes” are located on a retractable centerboard, or keel, beneath the hull. While in port, this keel is flush with the ship, but it is lowered once we reach deep water. The Reuben Lasker is equipped with an impressive array of six different sonar frequencies. Low frequencies, like the 18 kilohertz signal, penetrate deep into the ocean to map the seabed, while higher frequencies are better for detecting smaller organisms like krill in the upper water column. We primarily use the 38 kilohertz frequency to measure fish echoes. Anything in the water column with a different density than the surrounding seawaterโ€”whether it be a fish, squid, or the ocean floorโ€”reflects sound waves that our instruments carefully measure.

Omnidirectional and Multi-beam Sonars

Beyond the downward-looking sonar, we utilize an omnidirectional sonar mounted forward that scans in a radius around the ship. This helps us see fish near the surface that might be missed by the keel-mounted sensors. We also have multi-beam echo sounders, like the ME70 and MS70, which provide detailed three-dimensional views of fish schools and behavior. While these are invaluable for observing marine life, they are more difficult to calibrate for the precise biomass estimates provided by our primary systems.

Survey Transects and Navigation

The survey follows a series of transects that span the U.S. continental shelf from Mexico to Canada. These lines generally extend at least 35 miles offshore to ensure we capture the full range of the species we are monitoring. Each transect provides a localized estimate of biomass, and by repeating these measurements across the entire coast, we can calculate a mean population estimate with statistical confidence. The spacing between these linesโ€”currently 12.5 nautical milesโ€”is a careful balance between our available time at sea and the need for scientific precision. While navigating perpendicular to the coast can sometimes lead to a rougher ride in the troughs of the waves, it remains the most efficient and scientifically sound way to sample across the varying densities of marine life.

Did you Know?

The sonar system on the Reuben Lasker is so sensitive it can detect individual organisms based on their density relative to the water.

Interview with Brad Erisman, marine biologist about the use of the MVP 

Brad: The precision of our acoustic survey relies heavily on the physical properties of the water we traverse. Factors such as temperature and density significantly influence the strength and travel speed of sonar echoes. While we calibrate our instruments in San Diego, the conditions change as we move north along the coast. To maintain the accuracy of our biomass estimates, we must continuously adjust our parameters to account for variations in sound absorption and velocity within the water column.

The Moving Vessel Profiler (MVP)

This is where the MVP, or Moving Vessel Profiler, becomes indispensable. We deploy this specialized probe to capture a comprehensive temperature profile of the water column. These real-time measurements allow us to calculate essential coefficients for our acoustic data. Along every transect, we perform multiple deployments to ensure we have representative environmental data. This constant fine-tuning allows us to produce the most reliable estimates of fish populations possible.

Environmental Sensors

The MVP is a sophisticated tool, far more capable than a simple surface drifter. It is equipped with an array of sensors that measure salinity, chlorophyll levels, oxygen concentration, and sound speed. While a drifter only provides a surface snapshot, the MVP reveals the three-dimensional structure of the sea, highlighting fascinating features like thermoclines where warm, shallow water meets the colder, deeper ocean water.

Correlating Fish Patterns with Ocean Data

These environmental datasets help us explain the spatial and vertical distribution of the species we monitor. By collecting in situ data at the same fine scale as our sonar and trawl operations, we can identify correlations between habitat conditions and fish behavior. While satellite data provides a broad overview, the MVP gives us the high-resolution evidence needed to understand why schools appear in certain areas or why species patterns shift across different oceanographic breaks.

Efficiency at Sea

The beauty of the Moving Vessel Profiler is in its nameโ€”it allows us to sample while the ship is in motion. A traditional Conductivity, Temperature, and Depth (CTD) cast involves a large cage lowered from a stationary ship, which would force us to halt our acoustic sampling. The MVP allows us to gather the necessary data without sacrificing valuable time. Although it doesn’t collect water samples or reach the extreme depths of a stationary cast, it provides exactly what we need to keep the survey on schedule.

A Three-Dimensional View of the Habitat

Oceanographers use these data points to build complex 3D models of the marine environment. These models are vital for understanding fish preferences; for instance, if sardines migrate further north, we can often trace that movement to a specific temperature preference, such as 15-20 Cยฐ-degree water, shifting with the currents. This helps us distinguish between a population decline and a simple change in habitat location.

Climate Signals and Regional Patterns

While large-scale climate signals like El Niรฑo or La Niรฑa are often monitored via satellite, our shipboard data helps define how these patterns manifest regionally. By looking at the data across the entire coast, we see the localized reflections of these massive basin-wide shifts, providing a clear picture of how the changing climate impacts our West Coast ecosystems.

 Personal Log

Weโ€™ve run into windy conditions after we crossed over the border into Oregon. We only were able to do one trawl last night before we had to call it a night due to rough waters. Tonight, we were on watch until midnight to see if things would calm down but itโ€™s still too rocky. To fill the time, we are discovering the delightful world of Dungeons and Dragons, led by the artful storytelling of the Operations Officer, Mike Fuller.

Itโ€™s challenging walking down the hallways, and a large wave can scatter anything that isnโ€™t well secured. Luckily the Dramamine is doing its trick and I havenโ€™t felt queasy at all this week.

Science and Technology Log

The day before I left for my trip aboard NOAA Reuben Lasker, I received an exciting email from the Teacher at Sea program. I was going to have the opportunity to participate in NOAA’s Adopt-a-Drifter Program, and I would be getting three drifter buoys that I would be releasing along our journey north along the coastline. 

three drifting buoys sit on a metal table in the wet lab. each drifting buoy's surface float rests on its coiled up drogue. the surface float portions are covered in stickers and decorated with marker. we can see NOAA Teacher at Sea stickers, stickers from Churchhill High School, and drawings of octopus.
Three Drifters ready for deployment

A drifting buoy, frequently called a “drifter,” is designed primarily to track sea surface temperatures. They can also capture data on everything from winds and atmospheric pressure to salinity and wave height. As these buoys meander across the ocean, pushed along by currents, their internal sensors beam this information up to satellites circling overhead. By mapping their journey over time, scientists can piece together a detailed profile of how our oceans move.

Map of drift buoys and their respective deploying countries

To ensure it stays on track with the water rather than the wind, a drifter utilizes a “drogue,” which acts as an underwater sea anchor extending down about 20 meters (or 65 feet). This drogue is tethered to the surface float, ensuring they travel in tandem with the near-surface currents. Without that heavy drogue to steady it, a drifter would just be tossed about by the wind and waves, much like a beach ball skittering across the top of a swimming pool.

Drifter information is vital for mapping worldwide ocean currents and eddies, validating satellite readings, and constructing complex weather and climate models.  These sensors also help predict where pollutants might travel after a spill, how garbage moves through the ocean,  and even help track the path of approaching hurricanes. 

This data isnโ€™t just for scientistsโ€”the general public and students have full access to it. Through the Global Drifter Program, classes can follow their own adopted buoy or any others in the fleet in near real-time. Students can retrieve and plot coordinates, time stamps, and Sea Surface Temperature (SST) to create their own time series or map their drifterโ€™s journey over a day, a month, or even a full year.

This is why I have this opportunity to be part of this amazing study. It was suggested I personalize the buoys, so I reached out to a local print shop to see about getting Churchill High School stickers made, although I felt it was a long shot due to the short turnaround time. Luckily, QSL Printing saved the day, and all they wanted for compensation was a picture of the buoys covered with their stickers. I was so thankful for their help!

I named the buoys after my two sons and a family friendโ€™s daughter: Otto, Nicolai, and Zoe, respectively. Shaun Dolk at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) in Miami let me know that the best location to drop the drifters would be off the coast of Eureka, California. The shipโ€™s chief  scientist, Kevin Stierhoff, and I decided that deploying them every ยฝ hour would give some spacing between buoys, thereby decreasing the chance they would drift together. 

We dropped Otto overboard first, and I realized it was a little odd dropping something named after my child into the ocean. He quickly bobbed away into the distance and I hoped that he would have a safe passage to wherever he might end up. Nicolai and Zoe met a similar fate soon after, although Zoe was greeted by whales that were traveling alongside the ship. 

Drifter Deployment–Stacey (Teacher at Sea) & Melissa (marine biologist)

The expected/average lifetime of a drifter is around 450 days. Each drifter has a full identifier number, and the IMEI numbers are preprogrammed into each transmitter. The IMEI number is sent as a โ€œsignatureโ€ within each data message received. With nearly 1300 drifters transmitting every hour, it is essential to differentiate messages and separate them accordingly. 

Should you happen to encounter one of these drifting buoys, you should  reach out to the Global Drifter Program team with the details displayed on its surface float. In cases where the instrument is still functional and powered, they will coordinate its redeployment to continue its mission. While most of these instruments have a much shorter lifespan, the most resilient drifter ever documented managed to send back signals for an incredible 10 years, 4 months, and 21 days. Itโ€™ll be interesting to see how long my kiddos will be afloat!

Personal Log

Switching to working in the evening has been tiring, and itโ€™s sometimes unclear what day it is. I now have pork chops for breakfast, and french toast for dinner which hasnโ€™t been such a bad thing. Weโ€™re settling into our daily routine onboard. We haul up three trawls of fish every evening, as weather allows it. Weโ€™ve had great weather, and only a couple days of rougher seas. Speaking of whichโ€ฆhave you ever used a treadmill on a ship? You donโ€™t need to use the incline function, as youโ€™ll be going up and down with the waves. You definitely need to hang on and it adds an extra work out element to your exercise routine. 

Between trawls, the scientists have some downtime and weโ€™ve learned how to felt sea creatures. Here are some examples of their creations:

Felted ray, crab, and jellyfish

Did you Know?

sonar used to detect dolphin echolocation signals

Before we do any trawl for fish, we do a mammal watch 15 minutes before we put the net into the water. The net has a metal grate that is designed to keep any large creatures from entering, but itโ€™s possible for dolphins or sea lions to get entangled in the mesh. We scan the water for any splashing, sounds, or spoutings. Itโ€™s difficult to discern in the dark, however.

This year, the science team has acquired infrared binoculars, which helps tremendously. You can see almost as well as daylight viewing, and I was able to see whales that were in the distance very easily. There is also a sonar that can show dolphin echolocation soundings, which also assists crew in checking if they are in the area. We had to cancel a trawl this past week due to dolphins hanging around the ship, even after we tried moving to another area. Last night, a sea lion followed us a bit, but we were able to do our trawl after it lost interest.
