Geographic Area of Cruise: Pacific Northwest (Off the coast of California)
Date: 9/7/2019
Weather Data from Marietta, GA:
Latitude: 33.963900 Longitude: -84.492260 Sky Conditions: Clear Present Weather: Hot Visibility: 9 miles Windspeed: Less than 1 knot Temperature: Record high 97 degrees Fahrenheit
It’s been weeks since I disembarked in Newport, Oregon and left Fairweather behind. I still feel like I’m a part of the crew since I was welcomed so seamlessly into any job I tried to learn while Teacher at Sea. However, the crew is still working away as I continue to share my experiences with my students in Marietta, Georgia.
As I have been working on lessons for my classroom, I keep finding fun facts and information about ship life that I didn’t share in my previous posts. So, here is my final post and some of my most frequent questions by students answered:
Question 1: Where did you sleep?
I slept in a berth, I had a comfortable bed, drawers, a locker, and a sink. There was a TV too, which I never watched since a) I like to read more than watch TV and b) the ship would rock me to sleep so fast I could never stay up too long at bedtime!

My room aboard Fairweather
Question 2: What was the weather like when you were at sea?
Sunny!
Cloudy and foggy
Clear at sunset
Windy days!
Windy nights!
Really foggy some nights!
Some days (and nights) so foggy that they had to use the fog horn for safety!
Question 3: What animals did you see?
I highlighted animals in all of my posts and linked sites to learn more, go check it out! There is one animal I didn’t include in my posts that I would like to share with you! The first is the California Sea Lionfound in the Newport harbor. You could hear them from across the harbor so I had to go check them out!
See the video below:
California Sea Lions
Question 4: What happens next with the hydrographic survey work?
This is one of my favorite questions from students! It shows how much you have learned about this very important scientific work and are thinking about what is next. The hydrographic survey maps are now in post processing, where the survey technicians, Sam, Bekah, Joe, and Michelle are working hard to make sure the data is correct. I shared in a previous hydrographic survey blog an example of Fairweather’s hydrographic survey maps, I also checked in with the USGS scientists James Conrad and Peter Dartnell to see what they were doing with their research and they shared some information that will help answer this question.
From Peter Dartnell, USGS research scientist: “Here are a few maps of the bathymetry data we just collected including the area off Coos Bay, off Eureka, and a close-up view of the mud volcano. The map off Eureka includes data we collected last year. I thought it would be best to show the entire Trinidad Canyon.”
From James Conrad USGS research geologist: “Here is an image of a ridge that we mapped on the cruise. The yellow dots are locations of methane bubble plumes that mark seafloor seeps. In the next few weeks, another NOAA ship, the Lasker, is planning to lower a Remotely Operated Vehicle to the seafloor here to see what kinds of critters live around these seeps. Methane seeps are known to have unique and unusual biologic communities associated with them. For scale, the ridge is about 8 miles long.”

So, even though the research cruise is over, the research and follow up missions resulting from the research are ongoing and evolving every day.
Question 5: Would you go back if you could be a Teacher at Sea again?
YES! There is still so much to learn. I want to continue my own learning, but most importantly, lead my students to get excited about the important scientific research while keeping the mission of the NOAA close to their hearts: “To understand and predict changes in climate, weather, oceans, and coasts, to share that knowledge and information with others, and to conserve and manage coastal and marine ecosystems and resources. Dedicated to the understanding and stewardship of the environment.“
Fair winds and following seas Fairweather, I will treasure this experience always.

How did you find out about your current position at NOAA?
I met a NOAA recruiter at a job fair at Texas A & M, submitted resume and 3 weeks later I got the call! After that the lengthy background check and physical for Federal employees, I came to work at NOAA aboard Fairweather.
1) When you were a child, what was your dream career?
I wanted to be an astronaut when I was young. I looked into aeronautical engineering and attended a Federal Service academy – the United States Merchant Marine Academy. My Dad is an engineer and contractor, so I grew up on job sites and always had the mindset of math and science. I knew my career would be something in the STEM field
2) What was your
favorite subject in school?
My favorite class was
differential equations. Why I like
engineering so much is everything is one big puzzle, and differential equations
is like one big puzzle.
3) Why is what you do important to on the ship?
Engineers on ships are
essentially the lifeblood of the ship, we keep the ship moving. We are the electricians, plumbers, the
mechanics, and even the firefighters.
The ship can’t go anywhere without engineers!
4) What would you tell an elementary school student about your work that is important to you?
I enjoy solving the puzzles. When something goes wrong, I enjoy finding out why something is not working and then solving the problem. That is what is so rewarding — figuring out what is wrong and fixing it!
5) Where do you do most of your work?
In the engine room. That’s where I spend my 8-hour shifts. The engineering room is on A & B deck — the 2 bottom-most levels of the ship. That is where most of the mechanisms that run the ship are located.
6) What tool do you use in your work that you could not live without?
A crescent wrench! Mine is handy because it can measure and tell
you the exact size of the nut which makes things a lot easier!
7) If you could invent any tool to make your
work more efficient and cost were no object, what would it be and why?
I would invent a tool
that could reach bolts at odd angles.
Like a magnetic wrench that could adjust to the size bolt head you need
and could bend around the odd angles and apply torque when I need it.
8) What part of your job with NOAA did you least expect?
I never expected to be in Alaska!
9) How could teacher help students understand and appreciate NOAA engineering opportunities?
I think it would be
valuable to have better understanding of what we engineers do! It’s a
really cool job, with a really good salary, and very few people know there are
positions like this available.
10) What is your favorite part of your day when you are working and why?
Every day is a little
different, you are never doing the same thing over and over again. Something is always breaking and needs
immediate attention.
11) What was your favorite book growing up?
My favorite book
series when I was growing up was Junie B. Jones! I come from Florida and loved Jacques Cousteau.
He inspired me to become a scuba diver
at 17.
12) What do you think you would be doing if you were not working for NOAA?
I would be still be
working on a boat!
13) Do you have an outside hobby?
I love camping and hiking, I’ve hiked 40 miles
of the Appalachian Trail and
would like to hike the rest!
When you were a child, what was your dream career?
As a child, I always wanted to draw. I was drawing constantly and I wanted to somehow make my love for creating art into a career, whether that meant being a studio artist myself or helping to teach others to make art.
2. What was your favorite (and least favorite) subject in school?
Believe it or not, science! I grew to really enjoy my science classes starting in middle school and through high school, especially participating in the science fairs. My love for science was inversely related to my love for math. I started to dread all my mathematics courses as I went through high school, and really up into my earlier college years which often made my science courses difficult. During my junior year in college I took calculus taught by a great professor and things finally clicked!
3. At what point in your life did you realize you wanted to do the work you are doing now?
Sometime in between my junior and senior years in college, I realized I wanted to do what is I’m doing now. That’s when I was introduced to hydrography.
4. What do you enjoy the most (and the least) about your work?
I really enjoy working on the ocean and with small boats. It’s a really dynamic platform. The lifestyle that comes with living on a ship can be difficult. It’s a lot of traveling and spending time away from home.
5. Where do you do most of your work?
Most of my work is done on the ship in the Plot Room. It’s a big room on the ship where most of our processing systems live.
6. What tool do you use in your work that you could not live without?
A computer! Computers are used for data acquisition, processing, and delivery. Everything is done via some sort of processing/work station.
7. What part of your job with NOAA did you least expect to be doing?
I never thought I would be a NOAA Diver. I didn’t even know that NOAA had a dive program. Learning to be a working diver was an awesome experience and opportunity that I don’t think I would have ever had, or even would want to have outside of NOAA.
8. How could teachers help students understand and appreciate NOAA science?
Teachers could help students understand and appreciate NOAA science by sharing some of the awesome work we do that’s applicable to their classroom. NOAA is such a big administration with tons of cool science going on so by picking some interesting topics that are more relatable to their classroom audience might help engage their students.
9. What is your favorite part of your day when you are working and why?
When acquiring data, my favorite part of the day is the end, when the data is transferred and being processed. It’s not because the day’s over, but because I get to see all of the data we’ve collected throughout the day and remember the work that went into it. It’s also the beginning of the next stage of work for that dataset, the quality control stage.
10. What do you think you would be doing if you were not working for NOAA?
It’s hard to say, but I’m not sure I would be doing anything hydrography related. NOAA has been a great learning platform for me to become the hydrographer I am now. NOAA has really taught me to appreciate ocean science.
11. Do you have an outside hobby?
My outside hobby is painting. It can be hard to find space on the ship to paint, but traveling around Alaska and being on the water always inspires me to be more creative.
12. What is your favorite animal?
Picking one is pretty difficult, but I’m really into jellyfish right now. They seem like they have a low-stress lifestyle.
13. If you could go back in time and tell your 10 year old self something, what would it be?
“Relax, being 10 is way cooler than you think.”
14. Have you traveled anywhere interesting travels while studying Geology?
I traveled to Northern India as my field study in college. We were studying the water quality and management stemming from the Ganges River. Also, most of my geology labs in college were trips to the field which often meant the beach. Traveling and being outside is an added bonus while studying geology.

Iris Ekmanis is currently a Junior Officer with the NOAA Corps.
On this Teacher at Sea mission,
Officer Ekman is currently on bridge watch, and is a training and small craft
officer.
Current Position: Junior
Deck Officer on Bridge Watch, training officer, small boats officer
3-4 other duties in addition to
watch.
Years/Experience:
Years at NOAA: 2.5 months after a 4-month basic training
College and/or specialized training:
2017 Bachelors of Marine Science from
University of Hawaii
Junior Officer Ekmanis worked as a deckhand on tourism boats, dive boats, whale watching, and worked on a small live-aboard cruise ship.
When you were a child, what was your dream career?
I wanted to be a marine biologist – but then I fell in love with being out on the water and on boats. Surrounded by the science of hydrography, I really like driving small boats and like the navigation part of my job.
2. Do you have any plans to continue your education while working for NOAA?
We get the GI bill since we are uniformed service (after 3 years with NOAA) so I’m considering a master’s in marine biology.
3. What was your favorite subject in school?
My favorite subject was outdoor education. I went to high school in New Zealand so there were outdoor education, whitewater kayaks, rock climbing, caving. My favorite academic subjects were biology & geography.
4. At what point in your life did you realize you wanted to do the work you are doing now?
I heard about NOAA in college, so I applied, I completed basic training and have been working for 2 ½ months.
5. What would you tell an elementary school student about your work that is most important?
We are out here charting the seafloor to ensure safe navigation for other mariners who are traveling through the Pacific. All kinds of cruise ships, fisherman, and cargo ships travel through the Pacific and must get there safely. Also, it is important that we are researching the fault lines to learn more about earthquakes and tsunamis.
We navigate the ship to ensure safety and collaborate with the hydrotechs (hydrographic technicians) to make sure the ship’s travels are resulting in good hydrographic surveys.
6. What is the most enjoyable or exciting part of your work?
I would say it is constantly learning new skills. Every day, I’m on the bridge learning about navigation, on the launchers learning about hydrography, and the “office view” changes every day. Every single day is different, and most times wake up in a new place. I’m learning something new every day!
7. Where do you do most of your work?
Mostly on the bridge 8 hours a day, rest of the time working on computers, or my training workbooks, plotting courses, planning our next route. A lot of charting.
8. What tool do you use every day that you couldn’t live without?
Definitely the software systems that allow us to navigate, radar, etc.
9. What tool would you bring aboard to make your job easier?
Multi beam sonar that could see in front of us instead of below us, since we are in uncharted waters that would alleviate the possibility of us running into something.
10. Is there any part of your NOAA job that you didn’t expect?
The job is hands on right away, and the job is fast paced and very diverse. You started doing the jobs right away. I’m looking forward to learning more about hydro.
11. How could teachers help student understand and appreciate NOAA science?
12. What is the favorite part of your day and why?
My favorite time was in Alaska, in the launches (small boats) and navigating a vessel though the Inside Channel. Navigating through SE Alaska was beautiful! I also enjoyed seeing humpback whales and occasionally orcas.
13. What was your favorite book when you were growing up?
My favorite book series was Harry Potter when I was growing up. My idols were Jacques Cousteau and Sylvia Earle .
14. What would you be doing if you weren’t working for NOAA?
If I didn’t work for NOAA I would definitely be doing something in the marine science field or in the maritime industry, I love boats! I would probably be working on a boat or doing something in the ocean.
15. Do you have an outside hobby?
My outside hobbies include: paddle boarding, surfing, scuba, free diving, outrigger canoes were my passion growing up, hiking, camping, anything outdoors.
16. What is your favorite animal?
Hawaiianspinner dolphin and whale sharks.
17. If you could go back in time and tell you 10-year-old self something, what would it be?
Keep pursuing your dreams, don’t take life too seriously, enjoy life and enjoy the ride.

What
is Bathymetry and why is it important? Bathymetry is the foundation of the science of hydrography, which measures the
physical features of a water body.
We covered Hydrography
in the last blog post so we know it includes not only bathymetry, but
also the shape and features of the shoreline and more.
Bathymetry is defined as “the study of the “beds” or “floors” of water bodies, including the ocean, rivers, streams, and lakes.”
The term “bathymetry”
originally referred to the ocean’s depth relative to sea level, although it has
come to mean “submarine topography,” or the depths and shapes of underwater
terrain. In the same way that
topographic maps represent the three-dimensional features of land, bathymetric
maps illustrate the land that lies underwater. Variations in sea-floor relief may be depicted
by color and contour lines called depth contours or isobaths. (Click
here for source credit and more information from NOAA)
A bathymetric map looks like this (thanks Sam!):
Latest bathymetric maps! Can you see the newly discovered undersea canyon? (Southern coverage)
Latest bathymetric maps! Can you see the newly discovered mud volcano? (Northern Coverage)
Above are the first views of this part of the seafloor with a bathymetric map! (Color coded for depth – see the chart on the left)
Science and Technology Log:
Among the NOAA officers Navigating the ship, Hydrographic Technicians, and wage mariners aboard Fairweather, and the Teacher at Sea, there are also two guest USGS scientists: James Conrad, a research Geologist and Perter Dartnell, a physical scientist. USGS stands for United States Geographical Survey. The USGS was created by an act of Congress in 1879 and is the sole science agency for the Department of the Interior.
As a Teacher at Sea, I had time to talk with these USGS scientists and learn more about Bathymetry and why it is important not only to scientists, but also how this information can be used to keep us safe.
Discussion with James Conrad research Geologist who is utilizing the science of Bathymetry among others to map the Cascadia Region of the Pacific seafloor. The USGS scientists’ focus is mapping the Cascadia Subduction Zone where the Juan de Fuca tectonic plate is “diving” below the North American tectonic plate. Areas of particular interest to these scientists are finding new faults, faults that are known but we have little information about, mud volcanoes and subsequent “seeps,” and the overall goal is to understand the behavior of the mega thrusts in the Cascadia Region.

About
the visiting scientists:
James Conrad has a bachelor’s degree from U.C. Berkley and a master’s degree from San Jose State and has been at the USGS for 38 years.
A conversation with Research Geologist James Conrad:
What
do you want students to know about Geology?
Geology is a field where
there is still so much to discover, especially if you are doing hazards research
work-like earthquakes, tsunamis, landslides, coastal change, and climate change
issues
Were
you always interested in geology?
Not as a child, but I became a geology major because I had taken an introductory course – and was guided to geology by the university.
I
met you on a ship-where do most of your work?
Office is in Santa Cruz, but we go out in the field 1-4 times a year for a week up to 3 weeks.
Geology is a very young
science, the fact that continents move wasn’t proven until 1963. There is very little known about the earth,
and there is so much more to discover.
Peter Dartnell:
Peter Dartnell has Bachelor of Science in Oceanography from Humboldt State University and a Masters of Geography from San Francisco State and has been with the USGS for 28 years.
A conversation with Physical Scientist Peter Dartnell:
What
does a physical scientist study?
Physical Science is a
combination of the studies earth and computer sciences using computers &
technology to study earth.
Physical Science allows you
to do everything along the scientific “study train” from data collection, interpretation,
to publications.
What
are your publications used for?
Scientific publications from
the USGS (which is the science agency of the government) are used widely to
inform about potential geohazards and changes in the earth. We don’t make policy, but the information we
provide may be used drive policies, especially safety.
Anything
you want an aspiring physical scientist to know?
Even though you are studying
earth sciences in school, you’ll truly enjoy once you get out and start applying
what you’ve learned in the field with hands on science.
We’ve
met on a ship, where is it you do most of your work?
I spend 75% of my time in the
office and 25% in meetings or traveling to study
What
is your favorite part of being a Physical Scientist?
Seeing part of the ocean that nobody has ever seen for the first time. We are the first ones to see these recently mapped parts of the sea floor.
What
types of technology you use in physical science?
We use specialized software to acquire data and analyze the data we collect.
We also use Multibeam sonar software – bathymetry and acoustic backscatter
What
do you think are some misconceptions about physical science?
Because we are working off shore and water covers 71% of the earth, marine geology is in its infancy — we really need to have a complete map of the sea floor which is vitally important to understand the geology of the earth. When we don’t have all of these details, we are essentially operating blind. That’s why the work that NOAA is doing is so important and the research partnerships with USGS are so valuable.
Much of the geography of the
seafloor is driven by the oil industry which is required to release their acquired
data every 25 years. A lot of the deep
penetration data is all from oil surveys. Sea floor mapping is limited for pure research
purposes due to limited resources.

More about bathymetry and the NOAA and USGS mission:
I was lucky enough to attend a “Science Talk” by these USGS scientists which was titled the Subduction Zone Coastal & Marine Geohazards Project. The USGS scientists are guests aboard Fairweather like me.
The focus of the USGS research is along the 700-mile CascadiaSubduction Zone:
Map of Study Area. Image Credit: USGS scientists Peter Dartnell and James Conrad
This area is where the Juan de Fuca plate dives below the North American Plate at an approximate rate of 1.6 inches per year.
Subduction Zone
Image Credit: USGS scientists Peter Dartnell and James Conrad
Why is this subduction zone so important and why is NOAA Ship Fairweather out surveying the ocean floor in this area? That’s because the world’s largest and most destructive earthquakes occur along subduction zones. If we know the potential hazards, we can prepare people and potentially save lives.
To properly prepare, we need the following details:
What We Need to Prepare for Future Earthquakes Image Credit: USGS scientists Peter Dartnell and James Conrad
This is why the bathymetric maps of the sea floor are important, they can help predict the area and amount of shaking that may occur during an earthquake and predict the tsunami danger zones. Then we can make decisions for building codes, infrastructure (like strength of bridges), and escape routes for Tsunamis. I took the pictures below when I arrived in Newport, little did I know how the research the Fairweather is conducting and the science of hydrography and bathymetric maps play a part in warnings like these! (See below)
Through the hydrographic surveying being conducted aboard Fairweather, the NOAA crew and USGS scientists are creating bathymetric maps which have reveled exciting new finds, such as: new seafloor faults, mapping known faults in greater detail, discovering mud volcanoes and submarine landslides, and using the water column data to discover the “seeps” which are most likely releasing methane gas. See below.

When I first heard the term BATHYMETRY I had no idea how these detailed maps of the seafloor could hold so much critical information! It’s fascinating to watch this science happen right here and see the discoveries in real time.
Personal Log
This post begins the last week aboard Fairweather. I’m surprised about how quickly the ship has begun to feel “normal” to me. I know my way around backwards (aft) and forwards (bow) and enjoyed getting to know everyone better. Sean the IT specialist makes an amazing pot of French press coffee around 10:00 am and is kind enough to share with all. Bekah, Sam, Joe, and Michelle in Hydrography patiently answer dozens of questions and allow me to participate when possible. And the officers on the bridge answer all the questions and are very welcoming and generous with sharing information and their amazing views! Carrie and the kitchen crew make 3 amazing meals a day, and I’ve made some new workout buddies to try to stay healthy with all this wonderful food! The visiting scientists have been very nice about answering all my questions about bathymetry and geology. It’s great when you are writing and studying about geology to be able to turn around and ask a geologist a question!
I can’t believe how well I sleep on a ship! The ship is constantly rocking and for this teacher at sea, and for me, that means some seriously deep sleep. One thing I learned is to make sure all my belongings are secure before I go to bed. If you leave something unsecured, chances are they will be banging around in the middle of the night or get tossed off a shelf (not the best middle of the night surprise!). My room is very dark at night and I really don’t hear anything beyond the noise of the engines. You can barely hear the foghorn from my area towards the back of the ship which is lucky since those sleeping in the front of the ship could hear it all night! (Those friends look a little weary today.) I have to set an alarm, or I will just keep sleeping with the constant rocking motion that is so relaxing! Only 3 more nights of good ship sleep for me!
The fog horn sounds every 2 minutes when the conditions are, you know, foggy!
Following the excellent tutelage of the NOAA officers, hydrographers, and USGS scientists, it’s exciting to look at the screen in the hydrography lab and start a conversation about features of the sea floor that we are seeing (or seeing in detail) for the first time. On this mission, there have been new faults, mud volcanoes, and underwater canyons discovered. The science is so fascinating and so little is known about the research being conducted aboard Fairweather. I honestly had to “Google” the terms I am now so familiar with like Hydrographic survey, multi beam echo sounders, bathymetry, water column data, just to name a few.
That’s the thing about science that has been reinforced being a Teacher at Sea, no matter how much you think you know about the earth, you learn just how much we don’t know yet, and we’re just beginning to realize the vast amount that is left to discover.
