Science and Technology Log

For the past two days, NOAA Ship Fairweather has been anchored in Port Madison,  part of Puget Sound off the coast of Seattle, Washington.  The crew is currently stopped for a few days in Puget Sound before heading north to Alaska in order to complete the yearly Hydrographic Systems Readiness Review (HSRR).  During HSRR, the survey techs test all of the hydrographic survey equipment that will be used during the field season.  It’s essential to test and calibrate the equipment at the start of the season in order to ensure the data accuracy for upcoming projects.

The first part of HSRR began Thursday morning. Because NOAA Ship Fairweather spent winter at dock in Yaquina Bay, barnacles and algae were able to grow plentifully on the ship’s bottom, making it their home.  The dive team deployed to check the Fairweathers hull and clean off the sonar transducers, removing any biofouling (sea life that had built up on the ship’s bottom) from the winter in port.

 

On Thursday afternoon and Friday, the next phase of HSRR began.  On Friday, I was able to spend most of the day on the survey launches as a few of the survey techs conducted patch testing (a process for precisely determining an orientation of the launch’s sonar).  NOAA Ship Fairweather has four 28-foot launches, and I spent the morning on 2808, and then the afternoon on 2806.  When working on projects in relatively shallow waters, the Fairweather deploys these launches to collect data more efficiently as four launches can work on a project simultaneously.

The launches are driven by a coxswain, often a NOAA officer or deck hand, while a Hydrographer-in-Charge (HIC) plans track lines for the vessel to run.  Sometimes, a coxswain-in-training or HIC-in training will also join the launch.  As part of HSRR, the HIC chose a few track lines for the launch to run, and the coxswain, drove the launch back and forth on the lines at various speeds.  While we ran the track lines, the HIC was able to gather data by sending an acoustic ping from the sonar which reflects off the seafloor and is then recorded when it returns to the sonar.  The two-way travel time of the pin is measured, which (when coupled with the speed of sound through the water) can be used to calculate the water depth.

While in Port Madison, the crew will send all four of the Fairweatherlaunches out to run the same track lines and to ensure the data collected by each launch matches.  At night, after the HIC’s have gathered data, the survey techs spend hours in the plot room, looking at the day’s data and checking for any discrepancies.  The survey techs correct any errors in the data and the saved changes are sent back to each launch’s computing system.  This is known as calibrating.  By running patch tests and calibrating the launches to one another, survey techs are able to guarantee that data collected throughout the season is precise, no matter which launch is used for a given area.

Before and after running the patch tests, the crew deploys a CTD  The CTD measures the conductivity, temperature, and depth of the water.  The survey techs are interested in the CTD readings because this information helps them assess the speed of sound (or the sonar waves) in a given body of water.  In turn, knowing the speed of sound and the amount of time the CTD takes to reach the ocean floor, allows survey techs to calculate ocean depths.  (The classic distance equation, d=rt!)

Data Being Collected from the CDT on the Launch Monitor

Data Being Collected from the CDT on the Launch Monitor

Conductivity refers to the ability of the given water sample to pass an electrical current.  Survey techs are interested in the conductivity, because the conductivity is another way to gauge the salinity (or “saltiness” of the water).  The more salt in a sample of ocean water, the greater the ocean water’s conductivity and the faster the sound waves travel.  Next is temperature.  Water closer to the surface is warmer, and thus, sound will travel faster closer to the surface.  Conversely, the cooler the temperature, the slower the sound waves travel.  The final measurement is depth, or pressure.  The deeper the water, the greater the pressure.  Greater depths increase the speed of the sonar waves.  The average speed of sound in the water is 1,500 m/s.  By comparison, the average speed of sound in air is about 340m/s.

Night Processing of Data in the Plot Room

Night Processing of Data in the Plot Room

After dinner, survey techs are assigned to night data processing.  I joined one of the survey techs, Ali, who was kind enough to explain how the launch data is analyzed.  One interesting note is the red light in the plot room.  The red light is used because the plot room is next to the bridge, where the officers and deck crew keep watch.  The red lights help the crew keep their eyes ready for night watch, so those processing data also work under red lights.

A "Painting" of Collected Data: Different Colors Represent Differing Depths

A “Painting” of Collected Data: Different Colors Represent Differing Depths

In the above photograph, notice the various colors representing the differing ocean depths.  In this case, red is shallower and purple is deeper.  Notice that as the survey tech, hovers over a datapoint with her mouse, the data collected by Fairweather launch 2807 is shown as a coordinate with a depth of 168.3 meters.  Creating a color “painting” of the data points is helpful because the changing colors help the survey techs understand the slope of the ocean floor; closer together colors mean a steeper slope or a sharp increase in depth, whereas larger swatches of the same color mean a flatter seafloor.

The green lines in the picture represent the “lines” that the launch ran, meaning the area where the coxswain drove back and forth in the boat at varying speeds.  Notice that there are two lines as the launches always run two lines to ensure accuracy.  As the launch is driven back and forth in the water, the transducers on the bottom of the launch emits multi-beam sonar, and sound waves ping off the ocean floor several times per second, sending sound waves back to the launch which are translated into millions of data points by the survey techs.

The survey techs use various computer programs and imaging software to analyze the data.  Above, the survey techs can look at a 3D cross-section of the data, which essentially looks like a virtual map of the sea floor.  In the bottom right corner, the survey tech compares two lines for accuracy, one with data points colored red, the other green.  When the lines line up exactly, precision is ensured.  The survey techs analyze the data to make sure the rocking of the boat in any direction (front/back, side-to-side, etc.) won’t interfere with mapping accuracy later in the season.  Finally, survey techs compare their work with each other to ensure precise calibration.

Personal Log

One of my favorite things about being onboard NOAA Ship Fairweather are the tremendous views every time I look outside.  Sunrises and sunsets are spectacular.  We’ve had some really great weather over the last few days, and though it has been a bit chilly, the skies have been fairly clear.

Did You Know?

On nautical charts (or maps), units of measurement vary.  Ocean depths can be marked in feet, meters, or fathoms. Fathoms, like knots, is another term steeped in nautical history.  When sailors used to measure ocean depths by hanging rope over the side of a vessel, they would pull in the line, looping the rope from hand to hand.  The distance of the rope from one outstretched hand to another (a sailor’s wingspan) became known as a fathom.

Challenge #2  – Devotion 7th Graders: Measure your wingspan, the distance from one outstretched hand to another.  Then measure four other friends, classmates, or family members’ wingspans.  What is the median wingspan for you and your friends?  What is the mean wingspan for you and your friends?  What is the mean absolute deviation for your collective wingspans?  One fathom is equal to 1.8288 meters or 6 feet.  If one fathom is the average sailor’s wingspan, how do your wingspans compare?  Present your findings on a 8.5x11inch paper as a mini-poster.  Include illustrations and calculations.

Crew Interviews

Another successful scientist is Peter Pyle.  Peter became interested in Ornithology while helping his dad, a meteorologist, band birds in their backyard in Oahu, Hawaii.  Peter attended Swarthmore College and received his BA in Biology.  Peter who loves field work lived on the Farallon Islands for 24 years as a field biologist. When Peter is not  doing field work, he is busily writing scientific papers and manuals to compliment field guides for Ornithologists.  His manuals help age/sex determination, species ID, and are written for “bird in hand” observations.  Peter’s favorite bird is a Bristle-thighed Curlew, which is a rare bird that breeds in Alaska and winters in Hawaii and the tropical Pacific. Peter likes it because it acts like a goofball. Peter, who is married, has an understanding and independent wife. Peter’s advice to someone who would like to be an Ornithologist is to be a field person. In the field you get dirty, have to be patient; you may spend hours in cold blinds waiting.  You have to have a passion for biology really be successful. Lastly, Peter advises that if your heart is in the right place, you’ll be a successful biologist.

Rich Pagen (back), Tim O’Toole

Another Ornithologist on this mission is Rich Pagen. Rich, who did his undergrad work in Environmental Studies, received his MA in Wildlife Biology.  Currently he lives in Minnesota, but in the past he lived on Catalina Island. He also taught an outdoor science class in Pasadena. During a Sea Bird meeting, he met Lisa Ballance who got him interested in the CSCAPE project. Previously, Rich has done shark satellite tagging, and has gone to Antarctica as a naturalist on a passenger ship. Rich will be completing this cruise as a Bird Observer.

If this group of scientists could have an action figure, it would be Juan Carlos Salinas.  Juan is in charge of tissue biopsy of the whales and dolphins. He is able to obtain these biopsies in very difficult circumstances. Juan who lives in Mexico City was hand picked  for these missions because of his talent for obtaining biopsy’s and his knowledge of marine mammals.  Juan learned biopsy sampling while in Baja in 1991 when studying humpback whales.

 Juan Carlos Salinas

Juan Carlos Salinas

Juan has had extensive field work experience and will be going to Hawaii with the McARTHUR II until November 30th.  He’s excited about his mission to Hawaii because you always see something different.  The Hawaiian waters are just being studied and what’s out there is relatively unknown. During the mission in Hawaii, he will do species ID, population studies, determine the health of the animals and finally learn about their genetics. Juan states that the field of biology is much more specialized than before with genetics being the big thing today. Another marine mammal observer that is talented in tissue biopsy is Ernesto Vasquez. Ernesto, who is married with a family, does field work cruises about once per year. He currently works at the National  Resource Ministry as a Marine Biologist in LaPaz, Mexico. He’s been with the government for 3 years.  He graduated school in 1998 with his degrees in Marine Biology.  While away, he e-mails his wife and family and he likes getting close to the animals, and getting tissue samples to.

Currently being trained in biopsy operations is marine biologist Tim O’Toole. Tim graduated from San Diego State University and did his post graduate work in Australia. An avid surfer, Tim enjoys the ocean and having the opportunity to gain further field experience working with marine mammals. While on this research cruise, he’s gaining experience from other scientists as well as reading, and learning Spanish. He does, however miss friends and family and likes to stay in touch.

Scientific Log 

Again we are seeing up to 80 marine mammals per day, and are doing well on our track lines.  The wind picked up, making it more difficult to do observations, but we are moving right along to get finished by Sunday. Some of the regulars are humpbacks, blue whales, Dall’s porpoise, fin whales, pacific-white sided dolphins, Risso’s dolphins and pinnipeds. I’ve attached photos of breaching humpbacks that we’ve seen. Hopefully through my logs and interviews you’ve learned about marine mammals, sea birds and ship operations.  To learn more about this mission go to the NOAA Fisheries Southwest Science Center website.  Look under “What’s new in the sanctuary.”

Personal Log

Upon reflecting on my adventure, I’ve found that the trip fully exceeded my expectations.  I expected to feel intimidated by the scientists and science, and to my relief was accepted and welcomed by all the scientists on board and they were most eager to teach me what  I needed to know. I’ve learned that to be a good scientist you must have good observational skills, computer skills, and be knowledgeable about data and statistics.  I’ve also learned that science takes time, is very exact, and requires you to be detail orientated.   Additionally, I’ve learned that to get along with others on a ship, you need to have a good sense of humor and be flexible. As the cruise comes to an end I’m really looking forward to getting home, doing further reflection on my experience and translating it into rich and meaningful curriculum for my students. Again, thanks to Karin, all the scientists, and the crew on board the McARTHUR II, this has been a wonderful experience.

As of this post, we have now finished all of our tracklines.   Tomorrow – Saturday we’ll be spending the day in Monterey Bay doing grab samples and additional small boat operations.  We will then head into port in San Francisco on Sunday as scheduled.

Crew Interviews: Scientists on board the McARTHUR II

The scientists on board the McARTHUR II are hardworking, dedicated people.  Their shifts can start at sunrise 6:00 am and end at sunset 9:00 pm.  Most scientists are on watch for two hours then off for two hours during the whole day.  While on watch they are observing mammals or birds, entering data and taking photographs.  When they’re off watch, they eat, do laundry, exercise and relax.  On board a ship, there are no weekends, so their schedule is set 7 days per week.

An excellent Senior Marine Mammal observer as well as the photo ID specialist is Cornelia Oedekoven. Cornelia is a soft spoken person who has an eye for detail.  She meticulously goes through the photos taken on the cruise then enters them in the data base.  This can be quite a project as some days there are as many 300 photos to be  processed. Cornelia, whose background is in marine biology, graduated from Rheinische Friedrich-Wilhelms Universitaet, Bonn, or the University of Bonn, Germany.  She received her “diplom” which is equivalent to a master’s degree in Biology.  She came to the United States to study marine ornithology in San Francisco. She now lives in San Diego.  She enjoys ship life because she’s met a lot of friends, and there is no commute to work. While on board, Cornelia has been known to do haircuts for other scientists and she also does oil painting.  In the past she’s done sea bird work, and she’ll be involved with CSCAPE until December 10th at which time she’ll go home to Germany to visit her family.  To be a successful marine biologist, she advises to get your degree, and then do as many internships as possible.

Holly Fearnbach

Holly Fearnbach

When things slow down on this cruise, you can count on Holly Fearnbach to say “we need a good Killer Whale sighting”. Holly, who has always liked marine biology, grew up near the beach. She received her BS in marine biology from the University of North Carolina, Wilmington, and from Old Dominion University she received her MS.  She’s looking to get her PhD from the University of Aberdeen in Scotland where she will focus her research on Killer Whales.  She states that right now there are 3 different types of Killer Whales, residents, off-shores and transients.  She’s excited because they are now finding another type in Antarctica. She loves the discovery of different types of marine mammals and her past work was with Bottlenose Dolphins.  She likes being on these field work cruises because she learns so much from the Cruise leaders and has been taught much from the scientists at the South West Fisheries Science Centers.  To become a scientist who studies whales and dolphins, she advises to do internships, and do volunteer work early in school. She also states that you need a good work ethic.  Holly, who is a marathon runner, actually trains while on ship.  She has completed 12 marathons and says that it is a great stress reliever.  She does however miss dry land and her friends and family while she is away.

 Jan Roletto

Jan Roletto

An Independent Observer on board the McARTHUR II is Jan Roletto. Jan is the Research Coordinator for the Gulf of the Farallones Marine Sanctuary.  Her primary role as Research Coordinator is to attract researchers to the Gulf of the Farallones National Marine Sanctuary. The Sanctuary is the management agency protecting these waters. The science department conducts research, monitoring, permitting, disturbance, and investigates pollution issues.  The Gulf of the Farallones National Marine Sanctuary protects the body of water from Bodega Head to Año Nuevo, south of San Francisco. The Farallon Islands are managed by the US Fish and Wildlife Service and the  National Wildlife Refuge works to maintain the seabirds and pinniped colonies on the islands. Jan’s background is in Marine Biology and she attended San Francisco State University. She really likes seeing different things and is challenged by the Sanctuary work. She states that sometimes they work with boat groundings, environmental issues, watershed issues, estuaries, pelagic and coastal areas; all very different ecosystems.  Her challenge as Research Coordinator is the lack of funding that the sanctuary receives for research and monitoring.  To enter the field of Marine Science, she advises to do your schooling, learn about computers, math and statistics.  She states that you will apply these disciplines to biology. Furthermore, she advises to volunteer and do unpaid internships as it is a small field and can be competitive.

Sage Tezak grew up in the Pacific Northwest and currently lives in San Francisco.  Sage has run a volunteer program for the last 3 years monitoring harbor seals for human related and other disturbances. That job brought her to San Francisco. Before that she lived in Humboldt and she’ll be starting grad school in 2 weeks at Prescott College in Conservational Biology/Environmental Studies.  She likes having the opportunity to gain further field experience and to see the  operations of a research cruise.

Scientific Log

Our days continue to be hazy and cloudy. We are getting more track lines done and are staying “on effort” more frequently, yesterday, we had around 70 sightings of marine mammals.  We are still seeing humpbacks, killer whales, Risso’s dolphins, harbor porpoises, pacific-white sided dolphins, minke whales, beaked whales, Dall’s porpoise, as well as California sea lions, northern fur seals, and elephant seals. The California current is one of the most productive in the world.

Yesterday, afternoon, about 3 miles from Big Sur, a Blue Whale surfaced right on the bow of the ship. It was beautiful to see the whale with the Big Sur coastline in the background.

Ornithologists are observing many birds including the resident breeders – Common Murre, Ashy Storm Petrels, Cassin’s Auklets, and Western Gulls.  Additionally, they’ve observed Black-footed Albatross – (Hawaiian Island breeder), Sooty Shearwaters (New Zealand breeders), Pink footed Shearwaters (breed in Chile), South Polar Skua’s (Antarctic breeder), Red Necked Phalaropes, Sabine’s Gulls (Artic breeders), Heerman’s comes up the California current from Mexico, also 95% breed on the same island as the Heerman’s Gull, the Terns winter in Northern Chile, and Southern Peru.

Personal Log

The days are getting busy with sightings as we continue to work track lines in the southern marine sanctuaries.  Although hazy and foggy, the weather has been quite pleasant.  The ocean has been relatively flat, with little waves and small swells.  This makes it easier to sight blows and marine mammals.

Today I’ll be editing video, and hopefully will have some good footage to share with you. We are trying a new way to get my logs off the ship.  I will still answer e-mail to scientist7.mcarthur@noaa.gov until Sunday afternoon.

Crew Interviews: “The Officers of the McARTHUR II”

Officers of the McARTHUR II are commissioned by NOAA.  They are uniformed personnel with the exception of the First Mate.  They all are assigned different watches and their primary responsibilities are, under direction of the Commanding Officer, to run the ship, navigate, take care of the ship’s medical needs and to make sure that shipboard operations are running smoothly.

The McARTHUR II has 6 officers on board – LCDR Morris, First Mate Greg Hubner (who is not uniformed), Operations Officer Nathan (Herb) Hancock, Navigation Officer Paul Householder, and Junior Officers, Ensign Steven Barry, and Ensign Paul Smidansky.  All NOAA Corps Officers have two years at sea, initially followed by three years of shore duty and rotate between sea and shore duty unless they are aviators.

Nathan Hancock

Operations Officer Nathan Hancock

First Mate Greg Hubner has been with NOAA for 26 years. He has a background in the Navy and started with NOAA as a deck hand. He is currently a licensed Officer and enjoys being out to sea. He likes seeing different countries and his favorite port is an island off of Spain. Another NOAA ship, RONALD H. BROWN, is involved with international research so some NOAA ships travel the world, and Greg has had the opportunity to see many countries and cultures.

Operations Officer Nathan Hancock is readily noticeable by his sense of humor and laughter.  Nathan graduated with a BS degree in Environmental Sciences and a MS degree in Geology and Geophysics. Nathan really enjoys his position as it enables him to “drive the boat”.  In the future, he would like to be transferred to the Key Largo Marine Sanctuary or fly into hurricanes. Nathan developed a love for the water when he was a child living at the ocean and running charters with his father a marine biologist.

Navigation Officer Paul Householder is also the medical person in charge.  He has a BA/BS in Chemical Engineering and joined NOAA after being laid off during the downsizing of the semi- conductor era. He’s been with the ship for over a year and is adjusting to sea life. He likes seeing the different places, but does miss his weekends.

Paul Householder

Navigation Officer Paul Householder

Ensigns Barry and Smidansky both have a background in Meteorology and Barry would like to join the National Weather Service. Barry, who joined NOAA in February ’04, enjoys the adventure of meeting different people.  On this tour, it will be his first time visiting Hawaii.  Ensign Smidansky, is a licensed airplane pilot, and is looking to join the air fleet of NOAA, but for the time being is enjoying his time at sea.

In order to become a NOAA Corps Officer, you need a college degree, preferable with a background in science or math.  You must be under 35 years old, with no arrests or criminal background.  Also, it takes between 6-9 months for your application to be processed and then the Secretary of the Commerce grants you a temporary commission.  The Senate grants you permanent status.  You must undergo three months training at the Merchant Marine Academy and then are assigned to a ship at sea to become a qualified deck officer. NOAA is constantly training officers for higher positions and Officer Householder will be promoted soon to Lt. Jr. Grade. All of the officers while professional and polite still have a sense of humor, they are gracious enough to keep answering the question – “where are we?”

Question: Malka, grade 5 – Where does the ship/vessel get fresh water?  The ship makes its own water, we take salt water and process it to turn it into fresh water.  Everyday we make 2,000 gallons worth. The process is started 10 miles out to sea.

Scientific Log 

Our days have been mostly foggy with the sun peaking through rarely. After not seeing the sun for days, we were all delighted when the bridge announced that there was sun and many of us ran outside right away!  Right now we’re outside of Pt. Reyes, continuing on transect lines. The animals we’ve observed lately are: a pod of Killer Whales feeding, several Humpback Whales, schools of Pacific White-sided Dolphins, Risso’s dolphins and Northern Right Whale dolphins.

The Zodiac was launched and tissue samples and photo ID was taken of the Killer Whales. (photos attached) This evening two Humpbacks gave us quite a show.  They rolled next to the ship, breached, and slapped their flippers. Many times we could see their bellies as they lazily made their way by the ship rolling and diving, quite peacefully.  Video and photo was taken of these amazing animals.

The bird observers have been especially busy. In the past few days they’ve identified Black-footed Albatross, Common Murre, lots of Sooty Shearwaters, Pink footed Shearwaters, Ashy Storm Petrels that breed on the Farallons, and Cassini’s Auklets. Also seen are South Polar Skua’s, and Red Neck Phalaropes who are Artic breeders.  We’ve also seen Mola Mola fish, and a Mako shark with a pointy snout.  We’re continuing Bongo Net Tows and continue to collect plankton, larvae and small jellyfish.

Personal Log

Thanks to Rich Pagen being back on board, I am now focusing more on taking video, completing interviews, doing logs and e-mail correspondence. My interviews have gone well; the crew has been responsive and also forgiving when I’ve made mistakes.  For the remainder of the trip, I’ll be focusing on interviewing more of the scientists, developing curriculum and completing logs.  It’s been great meeting all the crew and finding out more about them. With less than a week to go, I’m treasuring every moment. This has been a great trip!
