Science and Technology Log:
We have now finished our planned transects and are using our two additional days at sea to repeat two of the transect lines. This will allow us to see changes along the lines with observations 5 days apart. Our deep drops for eDNA (the genetic material shed by organisms in the water) will be at 2400m.
I have had a chance to help with the collection of samples of eDNA. The process begins right after the CTD rosette is lifted to the deck. Water is collected from the specific Niskin bottle that was filled at the various depths- either surface (0 m.), 500 m., 1000 m. or 2400 m. Next, the water samples are taken to the wet lab, where under laboratory conditions, they are filtered to collect eDNA which is then stored for future processing by MBARI.
I loved having a chance to participate in collecting the sample. Working with the equipment reminded me a lot of the joy I had in my college chemistry classes and it felt amazing to be making a contribution to science that will help understand this very special environment of Monterey Bay National Marine Sanctuary.
I have also been learning more about the ocean by looking at the CTD (water conductivity (salinity), temperature, and depth) profiles with the Reuben Lasker survey technicians, CC and Jaclyn. The survey technicians observe and record the data as the rosette descends. They also monitor how deep the rosette descends based on what they see on the sonar data, which is showing the overall distance to seamount. At the targeted depths and with a press of a mouse button, they close the Niskin bottle caps to capture water for eDNA sampling.
The data screens in the lab show how oxygen, temperature, salinity and chlorophyll change as we descend. At the surface the water temperature is 15°C (59°F) while at 1000m it is 3.5°C (38.3°F) and at 2400m it is 1.9°C (35.4 °F). Salinity at the surface is 33.25ppt, at 1000m it is 34.4ppt and at 2400m it is 34.65 ppt. Oxygen is 0.6 ml/L at the surface and is at its lowest 0.2 ml/L between 600 – 800m. The oxygen rises again as you go deeper than 800m and at 2400 it’s more than 2.0 ml/L. Chlorophyll is at its maximum at 43 m and is an indicator of the amount of phytoplankton in the upper layer of the ocean. Phytoplankton (microscopic algae) is the base of most food webs in the ocean. Thus, this data helps us better understand the ecosystem of the deep ocean.
Our seabird and marine mammal counts are going well, though we had the slowest day on Monday with only 47 animal sightings (11 mammals and 36 birds). Yet, all together for the week (with the 994 sightings shared in the last post), we had a total of 1,041 animal sightings for the 500 miles of survey.
As we repeated the survey line (16W) today (Tuesday), we had an exciting sighting of a pod of seven orcas! I have never seen orcas in California. I’ve also become far more skilled at sighting whale blows on the horizon and spotting sharks from the two black triangles peeking out of the water as they glide by. The various types of seabirds – like Leach’s Storm Petrels and Red-necked Phalaropes- are now second nature to me. Some of the most exciting moments have been finding the waving flippers of Guadalupe fur seals as they drift by clinging to a branch of kelp.
So far, I have probably put in 50 hours of observation time and I have been delighted in every moment of it. It is a bit like an easter egg hunt in the ocean. I have learned so much thanks to the support of the scientists who always think of me when any special sighting arises. Everyone makes the extra effort to make sure I have a chance to see it too.
Personal Log
I have been savoring the days at sea and the ever changing colors of the ocean from the deepest blue to silvery greys. I spend most of my days outdoors on the flying bridge perfecting my observation skills. Our shifts are complemented with delicious meals, after dinner card games and evenings in the gym. Life couldn’t be better and it is a real privilege to be part of this experience. Beside participating in science, I have been very busy interviewing people to better understand how everyone works together to make the mission successful. I’d like to share the stories of some of the people I have met.
NOAA Corps and the Crew: The Team at Sea that Makes Science Possible
Besides the 11 of us on the science team, we have the team that runs the ship composed of seven NOAA Corps officers and 18 crew. The crew includes survey technicians, electronics technicians, engineers, deckhands and stewards. NOAA Corps is one of the eight uniformed services of the United States. They are commissioned officers who support NOAA’s scientific and navigational missions by operating NOAA ships and aircraft. The Commanding Officer of the Lasker, CDR Aaron Maggied, shared that some NOAA Corps officers fly planes as hurricane hunters to collect data for forecasting hurricanes. Others, like himself, sail ships to make sure our ocean and its inhabitants are studied so that we can better understand and responsibly manage our natural resources, like our current sanctuary project. He also mentioned that early in his career he was called on to help in the Deepwater Horizon oil spill response effort in 2010. The officers have all been very supportive of having a teacher on board and readily answer any questions about their work.
Lt Cdr. Kelli-Ann Bliss Interview
Kell was the first officer I met on the ship. She welcomed me at the entrance to Coast Guard Island in Alameda and escorted me to the ship, kindly carrying my heavy duffle on her shoulders.
What is your job?
On Reuben Lasker, I am the XO, which stands for Executive Officer, and second in command. I have a background in science, like all NOAA Corps officers, and I support the scientists on the ship during sea assignments, and in different capacities when on land assignments. I work on the bridge and sail the ship safely to help the scientists get the data they need. This work is important because we need to understand how our planet works so we can survive as a species. I also mentor the Junior Officers (JOOD) as they work toward being Officers of the Deck (OOD). I also manage the crew details (payroll, vacation, staffing, approving purchasing, etc.) like an administrative assistant.
How did you come to NOAA?
I grew up in Rhode Island and spent summers sailing with my family all over New England. I went to Maine Maritime Academy and earned a degree in marine science. I worked in a lab on Cape Cod doing water testing after college. My college classmates encouraged me to apply for NOAA.
I have been in the NOAA Corps for 16 years and have been on 8 different NOAA ships. I have also served on various land assignments — including in Antarctica for 13 months. In Antarctica, I was half of a team with a NOAA technician. We were running experiments and collecting samples on behalf of scientists in their home locations. While staying over the winter, I enjoyed the gorgeous auroras (natural light displays in the sky) and the flat, snowy landscape of Antarctica. Currently I am stationed in Louisiana and awaiting the completion of the newest NOAA ship to the fleet, the NOAA Ship Oceanographer, where I will also serve as XO. My tasks will be much the same as here on Reuben Lasker, but additionally, I will hire the new crew and be part of the team that gets her ready for scientific missions.
What do you love about your job?
I love being at sea. You are in a new place every day and it is gorgeous. There is always something new to learn either through presentations, different weather conditions, or a new tool or technology on the ship.
What is your greatest challenge?
As you go up in the ranks, there is a lot of paperwork, which tends to mean a lot of sitting – but there’s always the ability to go up and stand a watch on the bridge to break it up. I also work to keep harmony and help to set a positive culture with the team which starts at the top.
When did you know you wanted to have an ocean focused career?
In middle school in Coventry, Rhode Island, I joined the shell club and learned all about shells and their history. For example, the ancient Romans boiled the murex shell and infused the purple color into fabric. Once a month, the club would travel to Boston and connect with the Malacological Club at Harvard and I would be exposed to even more people who were passionate about shells. I knew that I wanted to study science. For college, my family wanted me close by so I chose Maine Maritime Academy, this allowed me to merge my interests in science and being on the water.
What do you recommend to students who are interested in an ocean focused career?
Stay curious and ask questions. There are many ways to get into the field and people will share their knowledge. Always keep learning.

Interview of JOOD Camille Cube (Junior Officer of the Deck)
I met Camille Cube on my first visit to the bridge. I was so impressed by the calm and confident way she was steering the ship. In conversation, we were happy to discover that we both had Filipino roots. Camille kindly agreed to be interviewed.
What is your job/position?
I am the newest officer. My rank is Ensign and my position is called JOOD (Junior Officer of the Deck). I am learning to safely drive the ship and ensure everyone’s safety onboard. To steer the ship, I use navigational charts, radar, look out the windows, and other tools.
How did you come to NOAA?
I grew up in Northern Virginia. Then, I went to the University of Washington and majored in Environmental Science. I love the environment of both land and sea. During college, I did many internships. Two were with NOAA Fisheries. I also studied at Friday Harbor Labs on San Juan Island; in this 11 week residential program, I learned marine biology, went tidepooling and saw orcas. I also spent three months as an intern in Cambridge, England with the International Whaling Commission. After graduating from college, I worked for NOAA Fisheries in Sacramento (CA) as a natural resource and management specialist. I joined the NOAA Corps for a more hands-on experience. I love how the NOAA Corps changes jobs every few years. I will be on Reuben Lasker for two years; three months have passed so far.
How does the NOAA Corps work?
To apply, you fill out an application online, go to an interview and pass medical processing. If you are chosen, you begin three months of training at the US Coast Guard Academy in New London, Connecticut, alongside US Coast Guard officer candidates. This training has hands-on learning about navigation, the parts of a ship, safety, CPR, and fire fighting alongside classroom learning. I learned leadership and public speaking skills in my training and the experience has built my self-confidence. You begin your service as a junior officer and after 120 days of sailing, completing a workbook and proving that you can safely drive the ship, you become OOD (Officer of the Deck) qualified, which means you can drive the ship without supervision.
What is your work day like?
My watch, which is when I am driving the ship, begins at 11:15 p.m. and goes to 3:30 a.m. From 3:30 to 7:00 a.m., I do administrative work and eat breakfast. Sometimes, I exercise in the ship’s gym; our requirement is to work out 180 minutes a week. My second watch is from 7:15 to 11:30 a.m. After that, I am off duty, and I read, sleep or crochet. Right now I am making a purse that looks like a sheep.
What do you love about your job?
I love helping make science happen. NOAA’s work in science is really important. Often we work on research on fish populations and fish are very important for the economy and ecosystem. Collecting weather data is also important for weather forecasters. I love being able to do cool things on the ocean that I was never able to do in the office like steer the ship and see lots of wildlife. I also love the community in NOAA; we support each other, especially the other officers and the crew because we live and work so close together. A shout out to the stewards (ship’s cooks) for making Filipino food that reminds me of my family.
What is your greatest challenge?
Being away from home for long periods of time is a challenge. I live in San Diego now. Even though my husband visits me when we are in port, I have only been able to see my cat Mio once this year.
What was your favorite book in elementary school?
I was obsessed with Percy Jackson and wanted to be a demigod of Poseidon. I wished for water powers!
What do you recommend to students who are interested in an ocean focused career?
If you are near the ocean, get out and explore it in a hands-on way like tidepooling. If you are not near the ocean, watch documentaries and keep learning about the ocean. If you can, join a marine biology club.
I am excited to share information about career opportunities with NOAA with my students and family. I had never heard of this service before and now after experiencing the work of the NOAA Corps, I believe it is a wonderful opportunity. I also learned about another new to me career-the careers of wage mariners. It takes many essential skilled workers to sail these ships that make science happen.

Interview of Nick Sampson (Oiler)
I had a chance to interview Nick Sampson. He is a mariner and specifically works as an Oiler. We met in the mess hall (dining room) as he is outgoing and very curious about all the science we are doing on our mission. He also kindly took us on a tour of the engine room with fellow mariner Joe Johnston.
Nick Sampson is from Jacksonville Florida. He has a 5 year old daughter and his wife is expecting another child soon.
What is your job?
I am an Oiler on the ship which means I check the temperature gauges and maintain the ship. I keep the ship running, secure and dependable.
What do you love about your job?
I love that I am doing something positive. I enjoy people–I am a people person and I love to learn from others. You can see the world with this job, make good money and learn a lot. I have been to Hawaii, Guam, Saipan, Japan, South Korea, Germany and recently I spent 43 days in Alaska.
What is a challenge in your job?
Learning more about the machinery is a challenge but I am eager to learn. The job is good if you are single, but if you have kids it is difficult to be away. It is still a good job for supporting a family.
How did you know you wanted an ocean focused career?
My older brother is a mariner so I decided to do the same. I graduated from Blue Water Maritime School in Florida and have been working on ships for the last 7 years.
What are your words of advice?
Give it a try! Invest in yourself and you can learn a lot.
The Most Essential Crew: The Stewards
A final shout out- as Camille says- has to go to the stewards. From the first day, the food has been AMAZING!!! The smells of the cooking waft all the way up to the flying bridge. Our meals are at 7 am, 11 am, and 5 pm. Since the crew and scientist work a range of shifts, including the night shift, there is always a wide array of assorted snacks as well as easy to prepare meals like fancy ramen bowls. There are lots of organic choices, a fruit salad bar at breakfast, and a green salad bar at lunch. I have been enjoying the organic grassfed milk in my tea every morning.
The stewards, Arnold Dones and Judeni De Los Reyes, create food with great care and an element of magic. Since both have Filipino roots, they love to make some of the traditional foods like adobo and pancit (my favorite Filipino food). But they also love to test out new recipes. I am still thinking about the cabbage rolls from the first day. They tasted like a special grandmother’s recipe; Arnold shares that he researches recipes and gives them a try. Before working for NOAA, he was a cook for the Navy for 10 years.
Arnold loves his job on Lasker and takes great pride in carefully planning the menu even up to a year in advance. This way he can plan to have the right equipment and the right cooking time. Arnold “loves to cook everything” and likes to explore new foods. “Good food makes everyone function well both in terms of energy and morale. It makes people happy and I love to make everyone happy by giving them the best quality food and snacks.”
Did You Know?
Guadalupe Fur seals are members of the “eared fur seal” family. They breed on Guadalupe Island (off the coast of Mexico) and on the Channel Islands. They have been making a comeback since they were once hunted to near extinction in the 1700’s and 1800’s. They are now considered “threatened” on the Endangered Species list and research and conservation is helping their recovery. They feed on squid and small fish mostly at night. They dive from an average of 65’ to a maximum of 250’. They rest with their heads under water and their flippers poking out above water as pictured below. On this mission, we have been seeing both Northern Fur Seals and Guadalupe Fur Seals.
Please stay tuned for my final blog from shore…
What a small world! Lt. Cdr. Kelli Ann Bliss and I both benefited from the shell club at Coventry Middle School! I wrote about it in my intro blog, so it was quite a surprise to see it mentioned here as I am working on my next blog! Thank you, Jacqueline, for sharing your journey and her information with us all. – Cheryl Milliken
