Career Spotlight

Uplift Education, Mighty K-12 scholars: Did you know some people have jobs where they explore the ocean, study sea animals, and help take care of our planet? 

Some of you, even those already thinking ahead in middle or high school, might be wondering what kinds of jobs or studies you can pursue one day.  Well, today weโ€™re going to meet some real-life ocean heroes: the scientists on the science crew who are sailing aboard NOAA Ship Pisces for the larval bluefin tuna mission.   They come from all over the United States and are experts at what they do. 

Why are they awesome?  If youโ€™d like: go ahead and think, share, and then draw or write your responses on this digital whiteboard:

https://www.whiteboard.chat/board/963e0100-9dc6-4679-85ff-2116fdc539d1-pgNum-1

Based on some of your responsesโ€ฆ these scientists are curious like inquirers, hardworking and knowledgeable, and they show they are caring by helping protect sea life.  They are communicators who share what they know, and courageous learners who explore the unknown!  Now, letโ€™s learn more about our science crew to find out how you might be a sea explorer one day!

* Note: I’ll be updating this post throughout the cruise. These interviews were rephrased to fit into the blog. For full interview responses, please click here: https://docs.google.com/document/d/1bvKvswISdjFMMqG7QNoc8FDox74Ysey-Xp2ERMLvajc/edit?usp=sharing

Meet the Scientists!

Hi, Iโ€™m David Richardson! I live in South Kingstown, Rhode Island, but grew up in Sierra Madre, California. I studied Natural Resources at Cornell University, then went to grad school at the University of Miami. Iโ€™m the chief scientist on this cruise, which means I help plan how we collect data to meet our science goals. My research focuses on larval fish, fish migrations, and how ocean conditions affect fisheries. My favorite marine animal’s the sail fish. Theyโ€™re beautiful at every stage of life! I love science because it helps us make the world better. In fisheries science, our work helps keep fish populations healthy so people can continue to enjoy fishing and have access to food.

Fun fact: My first research was on baby eels near Barbados. I discovered and illustrated six types of eel larvae that were new to science! That experience showed me how much of the ocean is still a mystery. My advice: Pay attention in math and writing but also get outside! Observing nature is one of the best ways to become a great scientist.

My name’s Allison Black! Iโ€™m from eastern Connecticut and often at sea. I studied Zoo and Wildlife Biology at Malone University and worked briefly as a zookeeper before focusing on ornithology. My favorite (yet unseen) marine animal is the Wandering Albatross. They can travel over 75,000 miles a year! On this project, Iโ€™m surveying seabirds and marine mammals. I love the oceanโ€™s mystery and the chance to keep learning through different cruises. Fun fact: by yearโ€™s end, Iโ€™ll have 500 sea days! My advice: stay flexible, stay curious, and seize opportunities you didnโ€™t know existed.


I’m Chrissy Hernรกndez! I grew up in New Jersey and now live in Oxford, England. I earned my bachelorโ€™s from Columbia University and my PhD from the MIT-WHOI Joint Program in Oceanography. Iโ€™ve worked as a researcher at Cornell and Oxford. Iโ€™m a population ecologist who studies biological oceanography and theoretical ecology. My favorite marine animal is the bluefin tuna! Aboard the ship, I help deploy plankton nets, identify tuna larvae, and guide sampling efforts. I love the oceanโ€™s vastness and mystery, and how tiny organisms like phytoplankton produce half the worldโ€™s oxygen. Fun fact: I once shaved my head and tossed the hair overboard during an equator-crossing tradition!

Hi, I’m Autumn Moya! Iโ€™m from Colorado and now live in Silver Spring, Maryland. I studied Biology at Western Colorado University with a focus on environmental biology, and Iโ€™m finishing my Masterโ€™s in Coastal Science at the University of Southern Mississippi. My research models how offshore development might affect the Atlantic surf clam fishery. I’m currently a John A. Knauss Marine Policy Fellow with NOAAโ€™s Office of Marine and Aviation Operations. I support communications, policy, and events. Iโ€™m excited to join research cruises like this one. My favorite marine animal is the cuttlefish. Did you know they can change color as fast as a blink? Iโ€™ve always loved the ocean, even growing up in a landlocked state. Since finishing my bachelorโ€™s, Iโ€™ve lived in seven states! My advice to future scientists: stay curious and never hesitate to reach out. Science is for everyone!


Hi, I’m Amanda Jacobsen! I’m from Rhode Island. I studied Environmental Studies at Connecticut College and now I’m working on my masterโ€™s in Marine Biology at UMass Dartmouth. On this cruise, I help deploy nets and collect seawater to study the carbon in it. My favorite sea creature is the lumpfish. Look it up, itโ€™s cool! Iโ€™ve worked on over 80 boats, and I love biology because it lets me explore the hidden world of ocean life.

Sometimes only visible under a microscope.

My advice to you: Stay curious and try new things, you might discover something amazing or meet someone who inspires you!

Hi! My name is Kristen Walter and I live in Miami, Florida. I graduated from the College of William and Mary with a master’s in marine science. I now work for the University of Miami/CIMAS studying coral reef fishes and bluefin tuna! My favorite marine animal is probably the nudibranch! Iโ€™m here on this cruise to help locate larval bluefin tuna, set and recover nets, preserve and identify fish, and test out new methods of capture using light traps. A fun fact about me is that I got to participate in the Aquarius Reef Base Underwater Habitat in Key Largo when I was in grad school. If you’d like to get into marine science, look for summer internships. Many places offer programs for high school students. Get your feet wet. Anything is possible!

Personal Log

Over the weekend, we moved back onto NOAA Ship Pisces.  It felt nice to return after a few nights in a hotel while crew members got everything ready for our big mission. 

view of computer screens, keyboards, mice on a wooden desk in an interior room of the ship
When weโ€™re not setting things up, we spend time working in a place called the dry lab.  The dry lab has computers, machines, and tables for us to study the ocean data we collect during the mission.  Iโ€™ve been using this time to write my blog! 
broader view of the dry lab: metal tables, a wooden desk, computers, computer chairs, two unidentifiable people sitting, facing away from the camera
Many scientists also bring their laptops, journals, or books to read or work on.  Itโ€™s a quiet place where people come and go, but when itโ€™s time to work, everyone jumps in to help!
three women - one seated at a desk, two standing - are in discussion. the seated woman holds up a piece of plastic film with her left hand.
Scientists Kristen, Chrissy, and Sarah are making sure the light traps for our drifters (for catching fish) are ready.

Just like we practice fire drills and safety rules at school, there are also important rules and practice drills in case of emergencies.

Outside of each stateroom, or everyoneโ€™s rooms, there is information on where you report to and what your role is during emergencies.  Itโ€™s a good idea to study this information!

Safety first! I need to make sure I can stay afloat in case I ever have to evacuate into the water.

I tried on an immersion suit, or “Gumby suit,” to make sure I can float in water. It’s also designed to keep people warm in the water in case they have to abandon ship or go into the water.
Sinh, wearing his Teacher at Sea baseball cap, poses for a photo - making a shasta sign with his left hand and with his right, grasping the bagged survival suit and personal flotation device. he is standing on an outer deck.
So far, Iโ€™ve really enjoyed getting to know everyone on board.  Iโ€™m a lot more familiar with everything around the ship, including where all the rooms, crew members, and emergency equipment are.  Iโ€™m feeling excited about our mission once we set sail. 

Next time, Iโ€™ll be writing about a special tool we use called the CTD (Conductivity, Temperature, and Depth), which helps us learn more about the ocean!

Did you know?

NOAA ships have their own weather stations right on board.  That means they can measure wind, rain, temperature, and more.  Even while theyโ€™re sailing across the ocean!  What do you think scientists do with that information?

Mission: Woods Hole Oceanographic Institution (WHOI) Hawaii Ocean Time-series Station deployment (WHOTS-14)

Geographic Area of Cruise: Hawaii, Pacific Ocean

Date: Saturday, 29 July 2017

Weather Data from the Bridge:

Latitude & Longitude: 22o 45โ€™N, 157o 56โ€™W. Ship speed: 1.3 knots. Air temperature: 27.8oC. Sea temperature: 27.0oC. Humidity: 72%.Wind speed: 14 knots. Wind direction: 107 degrees. Sky cover: Few.

Science and Technology Log:

The most difficult part of Thursdayโ€™s buoy deployment was making sure the anchor was dropped on target. Throughout the day, shifting winds and currents kept pushing the ship away from the anchorโ€™s target location. There was constant communication between the shipโ€™s crew and the science team, correcting for this, but while everyone thought we were close when the anchor was dropped, nobody knew for sure until the anchorโ€™s actual location had been surveyed.

blog.4.Day6.image1
Triangulation of the WHOTS-14 buoyโ€™s anchor location. Look at how close the ‘Anchor at Depth’ location is to the ‘Target’ location — only 177.7 meters apart! Also notice that all three circles intersect at one point, meaning that the triangulated location of the anchor is quite accurate.

To survey the anchor site, the ship โ€œpingedโ€ (sent a signal to) the acoustic releases on the buoyโ€™s mooring line from three separate locations around the area where the anchor was dropped. This determines the distance from the ship to the anchor — or, more accurately, the distance from the ship to the acoustic releases. When all three distances are plotted (see the map above), the exact location of the buoyโ€™s anchor can be determined. Success! The buoyโ€™s anchor is 177.7 meters away from the target location — closer to the intended target than any other WHOTS deployment has gotten.


After deployment on Thursday, and all day Friday, the Hiโ€™ialakai stayed โ€œon stationโ€ about a quarter of a nautical mile downwind of the WHOTS-14 buoy, in order to verify that the instruments on the buoy were making accurate measurements. Because both meteorological and oceanographic measurements are being made, the buoyโ€™s data must be verified by two different methods.

Weather data from the buoy (air temperature, relative humidity, wind speed, etc.) is verified using measurements from the Hiโ€™ialakaiโ€™s own weather station and a separate set of instruments from NOAAโ€™sย Environmental Sciences Research Laboratory.ย This process is relatively simple, only requiring a few quick mouse clicks (to download the data), a flashdrive (to transfer the data), and a โ€œpleaseโ€ and โ€œthank youโ€.

blog.4.Day6.image2
July 28, 2017, 5:58PM HAST. Preparing the rosette for a CDT cast. Notice that the grey sampling bottles are open. If you look closely, you can see clear plastic โ€œwireโ€ running from the top of the sampling bottles to the center of the rosette. The wires are fastened on hooks which, when triggered by the computer in the lab, flip up, releasing the wire and closing the sampling bottle.

Salinity, temperature and depth measurements (from the MicroCats on the mooring line), on the other hand, are much more difficult to verify. In order to get the necessary โ€œin situโ€ oceanographic data (from measurements made close to the buoy), the water must be sampled directly. This is done buy doing something called a CTD cast — in this case, a specific type called a yo-yo.ย 

The contraption in the picture to the left is called a rosette. It consists of a PCV pipe frame, several grey sampling bottles around the outside of the frame, and multiple sets of instruments in the center (one primary and one backup) for each measurement being made.

blog.4.Day6.image3
July 28, 2017, 6:21PM HAST. On station at WHOTS-14, about halfway through a CDT cast (which typically take an hour). The cable that raises and lowers the rosette is running through the pulley in the upper right hand corner of the photo. The buoy is just visible in the distance, under the yellow arm.

The rosette is hooked to a stainless steel cable, hoisted over the side of the ship, and lowered into the water. Cable is cast (run out) until the rosette reaches a certain depth — which can be anything, really, depending on what measurements need to be made. For most of the verification measurements, this depth has been 250 meters. Then, the rosette is hauled up to the surface. And lowered back down. And raised up to the surface. And lowered back down. Itโ€™s easy to see why itโ€™s called a yo-yo!ย (CDT casts that go deeper — thousands of meters instead of hundreds — only go down and up once.)

For the verification process, the rosette is raised and lowered five times, with the instruments continuously measuring temperature, salinity and depth. On the final trip back to the surface, the sampling bottles are closed remotely, one at a time, at specific depths, by a computer in the shipโ€™s lab. (The sampling depths are determined during the cast, by identifying points of interest in the data. Typically, water is sampled at the lowest point of the cast and five meters below the surface, as well as where the salinity and oxygen content of the water is at its lowest.) Then, the rosette is hauled back on board, and water from the sampling bottles is emptied into smaller glass bottles, to be taken back to shore and more closely analyzed.

On this research cruise, the yo-yos are being done by scientists and student researchers from the University of Hawaii, who routinely work at the ALOHA site (where the WHOTS buoys are anchored). The yoyos are done at regular intervals throughout the day, with the first cast beginning at about 6AM HAST and the final one wrapping up at about midnight.

blog.4.Day6.image4
July 29, 2017, 9:43AM HAST. On station at WHOTS-13. One CDT cast has already been completed; another is scheduled to begin in about 15 minutes.

After the final yo-yo was complete at the WHOTS-14 buoy early Saturday morning, the Hiโ€™ialakai traveled to the WHOTS-13 buoy. Today and tomorrow (Sunday), more in situ meteorological and oceanographic verification measurements will be made at the WHOTS-13 site. All of this — the meteorological measurements, the yo-yos, the days rocking back and forth on the ocean swell — must happen in order to make sure that the data being recorded is consistent from one buoy to the next. If this is the case, then itโ€™s a good bet that any trends or changes in the data are real — caused by the environmental conditions — rather than differences in the instruments themselves.

Personal Log:

blog.4.Day6.image5
The Hiโ€™ialakaiโ€™s dry lab. Everyone is wearing either a sweatshirt or a jacket… are we sure this is Hawaii?

Most of the science teamโ€™s time is divided between the Hiโ€™ialakaiโ€™s deck and the labs (there are two; one wet, and one dry).ย  The wet lab contains stainless steel sinks, countertops, and an industrial freezer; on research cruises that focus on marine biology, samples can be stored there. Since the only samples being collected on this cruise are water, which donโ€™t need to be frozen, the freezer was turned off before we left port, and turned into additional storage space.ย  The dry lab (shown in the picture above) is essentially open office space, in use nearly 24 hours a day. The labs, like most living areas on the ship, are quite well air conditioned. It may be hot and humid outside, but inside, hoodies and hot coffee are both at a premium!

Did You Know?

The acronym โ€œCTDโ€ stands for conductivity, temperature and depth. But the MicroCats on the buoy mooring lines and the CTD casts are supposed to measure salinity, temperature and depth… so where does conductivity come in? It turns out that the salinity of the water canโ€™t be measured directly — but conductivity of the water can.

When salt is dissolved into water, it breaks into ions, which have positive and negative charges. In order to determine salinity, an instrument measuring conductivity will pass a small electrical current between two electrodes (conductors), and the voltage on either side of the electrodes is measured. Ions facilitate the flow of the electrical current through the water. Therefore conductivity, with the temperature of the water taken into account, can be used to determine the salinity.

What is your job here on the ship?

Survey Tech

What does that mean?

I have two similar but different jobs

  1. Run and monitor the ship’s scientific equipment
    • I help fixย things when they break down
    • I am the Liaison between the ship and the scientific party (we mean everything). Anything the scientist needs, the survey techs help provide it.
    • I know the capabilities of equipment.
      • For example, the fish lab is one of the most high tech fish labs in the world. Incredibly advanced.
  2. ย We work within the science spaces, so we are always around. Point of contact!
    • I work with deck department and with their help I deploy a lot of gear
    • Jack of all trades. We get to be involved with a little bit everything;computer software, electronics, plumbing, carpentry etc. I am also on the bridge for lookout sometimes.

Right now, I am planning for the marine mammal and deep water coral cruise. We are also takingย multi-beam data when we pass through certain points on this cruise that helps us prepare for future cruises.

When you are in the dry lab with us (deploying the bongo plankton nets or Conductivity-Temperature-Depth (CTD) unit) what do all of the techy things on your computer mean?

  • Left side of the screen: Winch Data (winch data, line speeds (how fast they are moving), depth, depth of instrument, how much line is out). There is also data from the ship’s meteorological sensors available as well.
    • Performance of the winches as well as the instrument information.

Winch and Weather Data. Photo by DJ Kast

  • Weather conditions that relate to the deployment of the instrument.
    • For example, wind conditions (speed and direction)
    • Set the wind on the starboard side so that the boat gets pushed away from the instruments and lines.
  • Right side of the screen: the Vertical profile of theCTD. Watching this to make sure theCTD is functioning correctly. Oceanographers use it differently, for example trying to find the chlorophyll maximum depth and the thermocline, where the temperature changes suddenly with depth.
    • My job is to make sure that the equipment is functional and collecting accurate, valid data.

  • Whenever the sensor on the CTD on the bongos is activated by seawater, the numbers show up on Geoff’sย screen. He then announces, “Weโ€™ve got numbers, lets Bongo!”ย ย It’s literally my favorite quote of the trip and makes me laugh every time he says it.
    • CTD numbers means that it is on, functioning properly, and is ready to be deployed.
    • Sometimes there is a software/ hardware glitch, or a plug or connection might fail. If this happens, the cast cannot be completed. So observing the CTD output is very important.
  • Label printing! This has Ot (Other), I (Ichthyoplankton), Z (zooplankton) designations to indicate the type of nets used on the bongo frames.

  • I will also do post processing, which summarizes everything.
    • ย To me its important to make sure we are properly collecting accurate data for the end user, I care about how the data is collected. I need to make sure that the sensors are all working and displaying the accurate data so that scientists can go ahead and use that data in their research.

How do you get trained to be a survey tech?

(He laughs.) Truthfully, it’s a lot of On the Job Training (OJT). I read manuals and study our various equipment, and so I have a full understanding of how all of our equipment works and how to fix something when it breaks.

*As a side note from the XO: You need a degree in science and some motivation to be a survey tech, and its a great job for recent college graduates because survey techs make pretty good money, ball-parking approximately $60,000 annually, and sometimes even more depending on the sailing schedule.*

While these next trainings are not directly part of my job as survey tech, the two trainings below are a part of being a well-rounded ship crew member.

  • Ship SCUBA divers- NOAA Dive School. This allows us to check on the ship’s echo-sounders, seawater intakes, propeller and rudder.
  • Medpic training – one of the ship’s medics. I do anything from minor first aid to assessing an injury to responding to medical emergencies. I am qualified to administer medicine but not prescribe it.

My background is actually in fisheries. I worked in a fisheries lab as a fisheries scientist, which is why I was originally brought onto the Henry B. Bigelow in the first place. I then realized I was more interested in the vessel operations, so I made the switch over to the survey department.

I was hired to do a lot of Bottom Trawl Surveys and would only go on cruises when they pertained to that particular survey. While I wasn’t on board a research vessel, I was a sailing instructor and a substitute teacher. I taught 8th grade social studies for a year as a long-term sub and what I’ve learned is that itโ€™s most important to teach students how to learn. It’s something that I use to explain new boat protocols and equipment to new crew.

I think that working and going to sea is a very unique experience, and even though the romantic idea of being on a research vessel is very different from the reality, it’s still an interesting life and I love it. I love going to sea.ย  I’ve spent about a decade of half year ship time on vessels. My wife keeps asking me, “When are you done going to sea?” My reply would be that I don’t know if I can ever be done. The ocean’s siren call always seems to call me back.

The Tenacity of a Scientist

The science crew has been divided into two teams โ€“ the day watch (noon to midnight), and the night watch (midnight to noon). Those who are on โ€œwatchโ€ are expected to be around the science labs while on duty. When TowCam is deployed, members of the science party on watch should be in the Dry Lab to monitor images and record data.

My watch is midnight to noon. Did I mention that my normal bedtime is 9:00? It will take a little while to get adjusted to this new schedule.

While the TowCam is in the water, the โ€œDry Labโ€ is bustling with activity. The TowCam operators, and some of the shipโ€™s crew, ensure that the equipment is safely deployed. After lowering TowCam to a specified depth, control of TowCam is passed from the Bridge to the TowCam pilots. It is interesting to see how this large piece of machinery is operated. The pilot uses a joystick to raise or lower TowCam to the correct depth just above the ocean floor. In addition to the joystick controller, the pilot must also interpret data that is being recorded by TowCam or the ship. Knowing the wind speed, tension of the winch wire, altimetry, and depth are all variables that help the pilot to make the most informed decisions about the placement of TowCam.

Even with the best planning and most precise implementation, sometimes things go awry. For example, a cable may break, or the altimeter may not be registering correctly. During a research cruise such as this, spare parts, tools, and other materials must be packed for the voyage. There are no trips to the hardware store when youโ€™re out in the middle of the ocean!

After yesterdayโ€™s practice dive, the engineers made some adjustments to TowCam so that it could work to its optimum capability. After adjustments have been made, a series of tests are run on TowCam to ensure that everything is working properly. After testing is complete, TowCam will be deployed again, allowing us another glimpse of the ocean floor.
