Crew Interviews: The Oceanographers

Every evening, one hour after sunset, while everyone on the ship is settling down to a good night’s rest, the oceanographers are busy, collecting samples, analyzing data and preparing for the next collection that has to be taken.

On board the McARTHUR II, you will find oceanographers, Mindy Kelley and Liz Zele.  When you first meet them you’re struck with their laughter, and the lightheartedness of these two scientists. You have to have a sense of humor when working at odd hours and conditions, and these two scientists know how to do serious science and yet still have fun.

Mindy Kelley has always enjoyed the ocean, especially when she visited Florida during family vacations.  Born in Pennsylvania, she treasured these trips and it led her to becoming a Marine Scientist.  She went to school at East Stroudsburg University of Pennsylvania and did summer field work through Wallops Island, VA.  Her field work led her to the Assateauge Island National Seashore where she gained extensive experience within the Barrier Islands and its marshes.  She obtained a BA in Biology and a BS in Marine Science/and Environmental Studies.

Her education took a total of 5 years.  Her first job was working with the Pennsylvania’s Department of Environment Protection – West Nile virus surveillance program. It was a great experience and pushed her forward to pursue a Marine Science career instead a settling on an environmental career.  Mindy really likes the computer aspect of being an oceanographer and hands on collecting of specimens.  She enjoys seeing her field work and data analysis come together and makes sense.  Working in the field is quite challenging.  This tour she will be gone from July 2nd to November 30th on the McARTHUR II.  After porting in San Francisco on the 24th she’ll head to Hawaii for the rest of her tour.  In order to meet the demands of ship life she relaxes by e-mailing, doing art projects, listening to music and practicing ballet. With a long history of practicing ballet, Mindy has adapted her routine so she can still work out on the ship.  While in port in Hawaii, she’ll attend some classes to make sure that her training is not being compromised.  Her advice to someone perusing a career in Oceanography would be to take a lot of math.  She says, “even if you don’t like math, when you can apply it to science, you’ll start to like it”. She also advises to take calculus, chemistry and physics.  Most importantly is the desire to make it work.

You have to be assertive and aggressive to work in the field and if you are, then you’ll be successful. Her goal is to return to school, and do further studies in computer science, physical and biological oceanography. A typical day in the life of an oceanographer is demanding.  They arise 1 hour before sunrise, around 4 am, collecting chrophyll,  nutrients, salt samples and productivity.  Next, throughout the day they collect surface chlorophyll, temperature, and record other data.  1 hour after sunset, they run a CTD station and then to a Bongo Tow. They also send daily reports to their home base in LaJolla, CA and monitor their data throughout the day.

Liz Zele
Liz Zele

Helping Mindy with this large task is Liz Zele.  Liz has a background in marine mammal identification and acoustics. She attended the University of San Diego where she received her degree in Marine Science with a biology emphasis.  After she graduated, she was involved with science education and informal science.  Liz has worked for NOAA for almost three years and this is her second long cruise. She enjoys field work because it lets her use what she learned in school, but she does admit however that she misses her family and friends while out at sea.

This project started for her in late June and will end on December 7th on board the DAVID STARR JORDAN working with another oceanographer. In order to relax on board a ship, Liz reads, watches movies, and goes to the gym.  In December, Liz hopes to buy a home and would like to open an education facility and continue with marine mammal acoustics.  For anyone wishing to enter the field of marine science she advises to volunteer and go after opportunities.  She states the field is very competitive so network and meet as many people as you can.

Scientific Log 

For the past few days, it’s been either foggy or too windy to do observations.  The last big sighting was on July 10th where we spotted about 30 Sperm Whales.  It was easy to identify the Sperm Whales as their blow is at a 45 degree angle.  Also Sperm Whales like to float at the top of the water so tracking and finding them is relatively easy.  Juan Carlos Salinas and Tim O’Toole, was able to obtain 10 different biopsy samples and Holly Fearnbach and Cornelia Oedekoven obtained photo id. Sperm whales are identified by their flukes, noting scratches, tears or missing pieces.  The scientists will try to identify specific whales.  In the attached pictures, you will see heads of Sperm Whales, note the blow hole on the side of one, also try and look for scratches or cuts on the flukes.

Because of the weather, observations have been slow.  Yesterday, I did observe a Humpback Whale breaching in the distance. Today I’ve been doing interviews, reading and doing e-mail correspondence.  Hopefully the weather will clear and we can go back to regular observations to see more wildlife.  Right now we’re off of Pt. Sir, near Big Sur and will continue to track right outside our own coastline.  Hope all is well.

Crew Interviews: “Serving up Yummy treats – The Cooks of the McARTHUR II”

pratt_interview6Sitting in the galley of the McARTHUR II, is like sitting in a warm kitchen with good food all around. The Cooks, Art Mercado- Chief Steward and 2nd Cook Art Mercado, has been with NOAA for 32 years. He started as Mess Man, then was promoted to 2nd cook, and then to Captain Steward. He’s sailed on the FAIRWEATHER, the Old McARTHUR, and the DISCOVERER to Guam. He’s sailed all over the world, including Hawaii, Costa Rica, Montecito, Mexico and the Galapagos Islands. His duties as Chief Steward is to order all the food, plan menus, supervise the 2nd cook, and do all the cooking with the 2nd cook. He cooks for 39-40 when there is a full compliment.  The best thing about his position is that it keeps him busy; he gets to talk to officers, crew and  scientists. Also he loves it when he can fish and has caught 110 lb. Yellow fin, 35 lb, Mahi Mahi, a 95 lb. Wahoo.  The only challenge is that sometimes he gets bored and sometime feels like he has too much to do.  When he gets bored, he watches TV and walks around the ship.  Art will be retiring in 1 ½ years and is thinking about Hawaii for his retirement years.  His most memorable cruise with NOAA is when he was in Alaska, not only did they have beach barbeques, but they also were allowed to go on-shore and see beaver, deer and moose.  His toughest cruise was in the Bering Strait when the weather became very rough. Even though his supplies were secure, they still fell off the shelves and made a big mess.

pratt_interview6aHelping Art is 2nd Cook Carrie Mortell, who has been with NOAA one year in August. Carrie’s experience is with a fishing boat in Alaska. She used to fish for Salmon in the summer and Black Cod and Halibut in the spring and fall. She loved the excitement of being out at sea on a 40 ft. Power Troller. At that time she lived in Prince Wales, Alaska. She enjoyed Alaska because she was surrounded by water and saw plenty of deer, moose and even bear.  She came to work for NOAA because she really likes being on the water, and is looking at either Alaska or Hawaii as her home port.  Her life on the McARTHUR II is very busy.  She needs to be at work at 5 am and finishes her day between 6-6:30 pm.  She likes the fast paced work on the McARTHUR and during her time off she likes to read, relax, exercise and play cards, Carrie along with Art prepare 3 meals per day, along with a morning snack.  Her favorite thing to bake is desserts and her favorite fish to eat is King Salmon, which she states is high in Omega-3.  Carrie’s having fun working for NOAA.

Scientific Log

Orcas found! Yesterday evening, approximately 8 Killer Whales were tracked and observed off the bow of the McARTHUR II. Scientists are right now trying to determine if they are resident, off-shore, or transient whales.  This they will do by looking at their saddles, the area just under the dorsal fin.  It has already been determined that this pod did not have a large bull as none of the whales had the very large dorsal fin.  Male bull fins can be as large at 6ft high. A southern resident Killer Whale is reported to be over 100 years old. Attached are 2 photos of the group we observed last night, and also an  older picture of a baby Orca, as evidenced by the yellow/pinkish coloring.  Thanks to Holly Fearnbach for the photos.

Today we are heading closer to the California coast, north of Bodega Bay. It has been foggy all day with no chance to do observations.

Personal Log

I had to get these out to all of you. Seeing so many wild Orcas was breathtaking. The flying bridge was full of oohs, and awes as everyone ran to get their cameras.  One of the animals spy-hopped to look around and we observed them for about 40 minutes.  I also thought you might enjoy the “baby” orca picture. Last night there were some juveniles in the group, as evidenced by the smaller dorsal fins.

Crew Interviews: Interview with the Engineering Dept.

The Engineering Department onboard the McARTHUR II is really amazing.  They are responsible for many of the operations on board.  They maintain and operate the 4 generators that provide all the electricity.  One generator can power 10, 075 light bulbs!  The electric/diesel engine has 3400 HP and consumes 2,850 gallons of fuel a day.  The ship that was built in 1984 was originally a Navy spy ship, spying on submarines.  The ship also makes its own water by taking in sea water, boiling it, letting it evaporate, treating it, and then it can be used by everyone on the ship.  The ship processes approx. 2400 gallons of water and 2200 gallons are used, so a 2 day reserve is kept on board.  The ship also has a machine shop to fix or create parts that my break down while out at sea.  The ship has two propellers and its top speed is 11.5 knots.

The ship can go 90 days at 3 knots. The ship has 7 levels including the fly bridge.  The person in charge of the Engineering Department is Jay Prueher who is the Chief Engineer. He’s worked for NOAA for 10 years and has a total of 20 years in Alaska. His favorite ports are Sitka and Juneau. What he likes best about ship life is no commute and dislikes being away from his family.  His wife, who won the Washington State lottery, resides in their home in the Cascade Mountains with their 6 cats and 6 dogs. During his time off, he likes to visit his daughter in warm and dry Tennessee. He really likes this department because all the engineers work together to envision what the scientists need to complete their mission.  Then they plan to make it real.  Even though Jay does enjoy his job, he plans to retire in 1 year, 11 months and 13 days, to spend time with his family in their beautiful home.

Thanks to all the engineering staff for touring me around and teaching me about the ship.

Scientific Log

Yesterday was a very slow day.  One of the scientists became ill so the ship was diverted to Coos Bay, Oregon. After a medical evaluation, it was decided that he would return to the ship at a later time.  We then left Coos Bay, and came into stormy weather, so operations were at a stand-still. We did still do bird observations, and we spotted Black footed Albatrosses, Sooty Shearwaters, Common Murres, Fulmars, and Leech’s Storm Petrels. At 2100, I met with Oceanographers, Liz Zele, and Mindy Kelly and proceeded to help with the CTD and the Bongo Nets.  The CTD gives scientists samples for conductivity, temperature, depth.  Next, a bongo net is lowered to a specific depth (300 meters) and brought to the surface at a constant angle. In this way a variety of fish and plankton can be collected and later identified. The specimens collected are very special because many of them are species in larval stage. By looking at this microscopic view of the ocean you  may easily identify it as the “nursery of the ocean”, displaying the many larval forms. The tests were concluded at approx. 2300 hrs.

Launching the zodiak
Launching the zodiak

Today was a much busier day.  Watch started at 0600 and as I was entering data for the bird observations we spotted some Blue whales.  Dr. Forney decided to launch the smaller boat (the Zodiac) for a closer look at the whales. I boarded the boat with the other scientists and we were lowered into the ocean. After getting everyone secure, we took off in pursuit of the Blue whales.  We spotted approximately 6 whales including a mother and calf. Biopsies were taken of these whales and we spent approximately 3 hours in pursuit to identify them.  We also identified Dall’s porpoise.

Personal log 

I must say climbing into a Zodiac in pursuit of whales has to be one of the most exhilarating experiences I’ve ever had.  The Zodiac skims the water at about 35 mph. and often we were airborne. The Blue whales that we found were unbelievably huge, as they can grow to 20-33 meters long.  We were approximately 100 meters away from them; I could hear their blows and was amazed at their gracefulness.  Besides the whales being exciting, all is going really well. I did have another bout of seasickness, but now that I’m wearing the patch, (medication for seasickness) I’m doing fine. The food here is very good, and there is down time to read, learn or watch movies.  Ship life is like a great  big family and everyone gets along pretty well.  Right now we are south/west of Crescent City, headed south to the Cordell Banks, Gulf of the Farallones, and Monterey Bay Marine Sanctuaries.  Soon, I’ll be in closer waters. Hope all is doing well back at home.  Thanks for responding to my logs, I welcome comments, corrections or questions. It keeps me busy!

P.S. In the Zodiac, I’m the one in the back with the orange “Mustang Suit” on, looking a little confused. If you look closely you can see the biopsy dart on the side of the Blue whale.

pratt_interview4Crew Interviews: the Commanding Officer

Today, I met with LCDR Daniel Morris on the McARTHUR II.  Morris is one of 270 uniformed officers of the NOAA Corps.  His assignment is varied with 2 years of duty on a ship and 3 years at shore. Morris’ background is in the Navy, where he attended the Naval Academy, and was promoted from Ensign to Lt. Jr. Grade, to Lt. Upon leaving the Navy, after some time he joined the NOAA Corps.  In NOAA he again started as an Ensign, Lt. Jr. Grade, Lt. Commander and now is a Lt. Commander.  In August, Dan will be completing this tour of ship duty and will then be posted at NOAA headquarters in Silver Spring, Maryland. While on board the McARTHUR II, Morris is responsible for all the operations on the ship, and the safety of personnel on board.  One of his challenges as Commanding Officer is to make the ship a better place to work and live.  Morris is on-call at all times aboard the McARTHUR II.  He is consulted with navigation questions and vessel traffic situations. During his down time he likes to ride his stationary bike and read. He keeps in contact with his wife who he met while he was a sailing instructor in the Navy and two daughters who live in Gloucester, Massachusetts via e-mail.  In the past, Dan has sailed the original McARTHUR, and the FERREL.  A port of call that he really enjoyed was in Panama, where he spent time with a friend whose backyard was in a rainforest. He describes life on board a ship like a very small city, and close attachments are made.  All personnel who have experienced storms and challenging situations work harder together and become closer.  There are 22 people who work together to run the ship, and Morris, admires the crew who work onboard a ship year in and year out. Morris also believes that educating others about sea life is important as he’s done outreach and worked with teachers to give them reports and pictures from sea to share with their students. His advice for anyone wanting a career in maritime is to learn the skills you need for working on board a ship.  He also stresses the importance of learning the Maritime traditions, and getting a mentor to help you to get the most out of a maritime career.

Scientific Log

Yesterday, we had the good fortune to see a school of Pacific White Sided dolphin, which swam at our bow for about 1/2 hr. A biopsy was taken of two of the animals, by Scientists, Tim O’Toole and Juan Carlos who used a crossbow with a special “grabber” attached to the arrow. A piece of skin and a piece of blubber will be analyzed.  Also swimming with the school were 2-3 baby dolphins.  Also spotted was a Humpback whale. A very busy day…

Today, we’ve spotted 2-3 Fin whales, along with a pod of Killer Whales.  The small boat was launched and tissue samples were taken from one of the Fin whales.  The Fin whale seemed rather curious as it approached the small boat at a close range.  The Killer Whales, however, were more cunning and a tissue sample could not be taken because their swimming pattern was very erratic.

As far as birds go, we spotted several Puffins, with beautiful markings on their heads; Black footed Albatrosses, Sooty Shearwaters, Leach’s Storm Petrels and lots of Seagulls.  Peter Pyle and Sophie Webb have trained me in the data entry part of their observations, so I am now helping them on the bridge when possible.  Tonight, I’ll be learning more about the CDT cast and also the Bongo Tow.

Personal Log

Yesterday was our first day out to sea, and my first experience with ocean swells.  I will admit I did develop sea sickness – or getting my sea legs as it’s called.  Chief Scientist Karen Forney, joked that may my sea legs grow quickly.  Ha! I’m now recovered, with no worse for wear. I guess it’s a rite of passage that all sea goers must experience.  So now I’m seasoned.  I’m very grateful to Chief Scientist Forney who in the middle of my sickness, came to my room and let me know about the dolphins outside.  She knew I wouldn’t want to miss it and she was right!  Another wonderful sight is the different tones of blue that can be seen when looking out over the water.  The weather has been nice, and we are now in the waters off of central Oregon.  We hope to be in central California by this weekend, depending on how things go.  The crew and scientists are extremely supportive and patient with all of my questions, and I’m learning a lot. I’ll post another log in a day or two.

Crew Interviews: “Making a Difference, One Survey at a Time”

Conservation, helping our oceans and educating others is Karin Forney’s goal. As a young girl, she was mystified by the ocean, but moved overseas to Germany.  Missing the ocean, she knew she had to return and when she did she became one of the leading experts in the field of whales and porpoises on the West Coast. Karin is one of a few scientists in the Coastal Marine Mammal Program which focuses on determining the numbers of marine life, human impact and what influences their population.  During the CSCAPE (Collaborative Survey Cetacean Abundance Pelagic Ecosystem) project, she is serving as Chief Scientist.  Her position while on the ship for 3 legs is that of Cruise Leader who is responsible for all aspects of the research program while under way. In port, at her home base in Santa Cruz, California, her job responsibilities are to assess marine mammal populations in the EEZ, (exclusive economic zone) of CA/OR/WA and  Hawaii. To do this she conducts surveys to estimate abundance and trends, studies stock structures and sub-populations.  She also estimates the human caused mortality of marine mammals by the fishing industry and ship strikes.  This she does by applying a formula to evaluate the level of human take that will still sustain a population.  If the level is too high she then works with the fisheries to bring down the mortality rates caused by humans.

Karin’s broad background in marine science has given her the skills and knowledge that she needs to make a difference.  Karin received her BA in Ecology Behavior and Evolution, her MA in Biology both from UC San Diego, and her PhD. in Oceanography, studying at the Scripps Institution of Oceanography.  Her dissertation focused on the variability of marine ecosystems and how it affects abundance, using environmental data to predict when and where marine mammals will be found.

Married to another Marine Biologist, Karin spends extensive amounts of time working in the field. She loves seeing the animals, yet sometimes it’s difficult when the weather is bad and observations can’t be made.  Karin has had many accomplishments, but she’s been personally moved by the fact that 18 years ago, she didn’t know anything about marine mammals, and now she’s a leading expert in her field. She’s grateful for the opportunities she’s had to learn about cetaceans and most importantly always tries to teach others about conservation efforts to help our marine environment. She advises to never underestimate the potential to do damage to our oceans, every meal, fish, and trash has implications for species.

For a person interested in becoming a Marine Scientist, she recommends that you develop a broad knowledge base, learn physics, chemistry and math.  You may like dolphins and whales, but you need to develop good skills.  Karin’s computer programming skills got her this job, even though she was a Marine Biologist.  She also recommends that you follow your heart, and do a good job at whatever you do.  Also be flexible and seize opportunities when they become available to you.

Answers to students questions: Elijah – 3rd grade:  How deep is the ocean? Karin: The deepest parts are over 30,000 feet, (10,000 meters), but most of the oceans are about 12,000 feet (400 meters) deep.  That’s about 2.5 miles deep.

Jennie 5th grade: Where do you find dolphins, whales, sea otters and seals? Karin: All in the ocean. (Ha) Some prefer closer to shore like the otters and Bottlenose Dolphins, some are far from shore like Sperm Whales.  Essentially, you can find marine mammals everywhere.

Amber – 5th grade:  What do jellyfish eat? Karin: Jellyfish are fierce predators.  They capture zooplankton, little fish and larval crabs. Because Jellyfish are clear, you can look into their stomachs and see what they’ve been eating,

Sana – 5th grade: Why are most small fish skinny and thin? Karin: Actually it’s hydrodynamic, they are like little torpedoes.  If they swim a lot they are long and thin, whereas; bottom dwellers are rounder. Also the little fish need to swim fast to get away.

Sana – 5th grade: Do sharks eat anything else but fishes? Karin: Sharks also eat marine mammals, including; seals, sea lions, squid, Blue sharks eat krill too.

Haleermah – 5th grade:  How much do dolphins weigh? Karin: The littlest ones weigh about as much as a fifth grader, (90 lbs).  The biggest ones- a male Killer Whale, can weigh over 8 tons.

Haleermah – 5th grade:  Do whales ever bite? Karin: Baleen whales have no teeth, they swallow things whole, toothed whales – the dolphins will bite, sort of like a “bad dog”.  Killer Whales generally don’t bite people, but they will bite each other.

Vince Rosato – 4th/5th grade Teacher – How many varieties of dolphins are there?  What is the percent of Bottlenose Dolphins?  What are the differences between porpoises and dolphins?

Karin: There are approximately 40 different dolphin species.  The Bottlenose is the most abundant near shore, yet they are a small fraction of the total dolphin population.  Less than 10% of all dolphins are Bottlenose. The difference between porpoise and dolphins are:

  1. Their skull shape – the porpoise has a blunt head,
  2. Teeth – tooth shape in a dolphin is conical, the porpoise is spade like.
  3. Porpoises are in smaller groups – less social.
  4. Porpoises are generally found in the higher latitudes except the Finless porpoise.

Scientific Log

Chief Scientist Karin Forney called all the scientists together for our first meeting at 0930 in the dry lab.  She gave an overview of the schedule of operations for our cruise and explained the day’s activities which were drills, CDT calibration, and scientist set-up and prep. The CDT or Conductivity, Temperature/Depth devices are used to get readings of salinity, temperature, depth, density and conductivity of the ocean water.  The CDT will be lowered to 500 meters when deployed.  Scientists also set-up their stations and  prepared for their busy days ahead. I worked with Rich Pagan, Sophie Webb, and Peter Pyle to create range finders out of pencils.  The range finders will help them determine whether the birds they observe are at 300, 200 or 100 meter distance.

Personal Log

Beautiful fireworks, warm weather and a wonderful array of boats showed Seattle in its glory! I spent the evening on board the McARTHUR which had an awesome view of the fireworks. What a send off for our cruise the next day.

I awoke to the smell of breakfast cooking and looked forward to today’s launch. We left Seattle, at 0930, and headed out of Lake Union.  After motoring through two draw bridges – the Fremont Bridge and the Ballard Bridge, we then got a special treat by going through the government locks – or the Hiram M. Chittam locks.  Locks are used to raise or lower water levels to allow passage from one body of water to another.  In this case, we were leaving Lake Union (freshwater) and going to Elliot Bay (salt water).  We waited patiently as the gates closed, and the water lowered us down for passage into Elliot Bay.  Upon leaving Elliot Bay, we dropped anchor to start the CDT calibration.  We then had an abandon ship drill in which I had to put on a very funny orange suit, affectionately know as Gumby suits.  As soon as it was donned, Chief Scientist Forney and Jan Rolleto ran to get their cameras because I looked so comical.  Finally, we had a fire drill and then the scientists set to work.  It was really fun working with Rich, Jim and Sophie. Sophie Webb has published two children’s books, Looking for Seabirds and My Season with Penguins, which are very well done and illustrated.  Recommended reading….. Right now, we’re still anchored in Elliot Bay with a beautiful view of the Seattle skyline, the Space Needle and Mt. Rainer. Tonight we’ll head off to the ocean and all the wonders we will see.
