TAS Dana Chu profile picHello from Sacramento, California! My name is Dana Chu and I am a Math and Science teacher and an Education Specialist at Florin High School.   This year I also teach a class called Multiple Strategies for Academics and Transitions and support a Spanish 1 class.   Florin High School has a diverse population of over 1,400 students that speak nineteen different languages. After school, I serve as an advisor to the Florin High School Watershed Team which is composed of students from all grade levels.

I am a firm believer that providing students with the opportunity to gain first-hand experience in wildlife areas and natural habitats is the key to inspiring them to become responsible stewards of their environment, both land and water. Our school is within walking distance of several local creeks. The Cosumnes River Preserve and the Yolo Bypass Wildlife Area, both of which serve as protected habitat and crucial feeding ground for migrating birds, are a short drive away.   We are also fortunate to be close to the American River where anadromous fish such as the Chinook salmon and Steelhead trout spawn. Salmon fry raised in the classroom through the Fish in the Classroom Program from Nimbus Fish Hatchery will be released there. Throughout the year, some of our students participate on field trips to these locations.   I can’t wait to share my Teacher at Sea experience with all of my students, especially because the water from our local creek and rivers eventually all feed into the ocean.

I applied for the NOAA Teacher at Sea program because I am very interested in sea turtles, ocean plastic pollution, and birds. I love being out on water whenever the opportunity arises and taking photographs of nature. I also want to learn from and directly work with scientists in the field. Having never traveled in the ocean for an extended period of time before, this research trip is a unique and exciting learning opportunity and chance for me to engage in many first-hand experiences. With ocean plastic pollution being a serious issue, I wonder what we will come across during the days while I am at sea. I can’t wait to sail out on the NOAA Ship Bell Shimada and to assist with scientific research in the Pacific Ocean! For more specific details on this expedition, please check the links for the Ship and the Mission.

In the meantime, I am in the midst of preparing for my upcoming scientific adventure. I am packing the last items needed for this research trip.   At school, the 9th graders are finishing up the Water and Ocean unit with a marine animal research project. I hope to bring back relevant information to share. My 11th graders are working on their career transition portfolios and mock job interviews. I look forward to learning about the different types of scientific and marine careers available from the members of this research cruise so I can inform my students of other potential careers they might have not considered.

When you hear from me next, I will have sailed out of San Francisco, California and experienced my first days of working and living at sea. I look forward to seeing the various pelagic birds plus marine mammals and invertebrates within their natural habitat. I am so excited to be part of this expedition!

Date: Friday, July 26, 2013

Weather Data:

  • Wind Speed: 7.8 kts
  • Surface Water Temperature: 58.3 Degrees Fahrenheit
  • Air Temperature: 55.4 Degrees Fahrenheit
  • Relative Humidity: 90%
  • Barometric Pressure: 30.05 in

Science and Technology Log:

ACCESS is a project that contributes to a regional characterization and monitoring of the physical and biological components of the pelagic ecosystem of Cordell Bank, Gulf of the Farallones, and northern Monterey Bay National Marine Sanctuaries.  During our cruise we are collecting data in these sanctuaries. Over the last three days I have observed and helped the ACCESS scientists collect physical, chemical, and biological properties of the water, plankton, marine mammals, and sea birds. Each of these are measured by a different ACCESS team of researchers in a different area of the research vessel, R/V Fulmar.

Plankton and water are collected and measured on the back deck of the ship.  The water is measured in a few ways.  First, a CTD (conductivity, temperature, and depth) and Niskin are lowered into the water between 35- 200 meters depending on the location on the line and depth of the water. The CTD measures the conductivity to calculate salinity, temperature, and relative depth within the water column.  The Niskin collects a water sample at the same location as the CTD.  These water samples are to tested for pH to measure the acidity of the water.  Finally, Dru Devlin and I are collecting a surface water sample for nutrients and a phytoplankton samples for the California Department of Public Health, as part of an early warning program for harmful algal blooms that can impact the shellfish we eat.

This CTD measure conductivity (salinity), temperature, and depth.

This CTD measures conductivity (salinity), temperature, and depth.

There are four different plankton collections.  The first collection is with a small hoop net (0.5 meter diameter) used to sample very small plankton, from where foraminifera will be separated later in the lab.  Foraminifera shell morphology and the oxygen isotopes of the shell are examined to investigate past and present climates and impacts of acidity on shell formation.  Next, a larger hoop net (1 meter diameter) collects samples of plankton in the upper 50 m of the water, which will be used to investigate the abundance, species, reproductive patterns, and locations.  When the research vessel was close to the end of the line and the continental shelf, the Tucker Trawl was released to collect three samples of plankton near the bottom.  When we processed these samples the majority of the organisms were krill.  Finally, Dru Devlin and I collected plankton samples 30 feet below the surface to send to the California Department of Health Services because they are interested in the presence and abundance of species that produce toxins.

On the top deck, the ACCESS observers watch for marine mammals and sea birds and call them out to the data recorder  to log the sightings into a waterproof computer.  This data will be used to relate the spatial patterns of bird and mammal distribution with oceanographic patterns and to understand the seasonal changes in the pelagic ecosystem.

Personal Log:

My favorite sighting so far was the leatherback sea turtle.  Seven years ago and last summer I took a group of Berkeley High School students to Costa Rica to participate in a sea turtle conservation project with Ecology Project International.  On these trips we saw a female leatherback laying her eggs and a hatchling making its way to the ocean.  It was great to see the next stage of development when the leatherback popped its head out of the water several hundred miles from their breeding grounds.

Did you know?

Humpback Whales have bad breath?  Yesterday we got to smell it first hand when two humpback whales decided to circle our boat and were close enough for us to smell their breath.  It’s like rotting fish and sour milk mixed together.

Day 1, July 23, 2012

Wow! I have been preparing for this day for months and now I’m here.  This is the adventure of a lifetime.  I’m so excited to tell everyone about everything that I’ve done so far and I’ve only been on board for two days.

Travel and Arrival

Me and Dad at Lunch

Me and Dad at Lunch, Picture by Karen Romito

I set off early Monday July 23, 2012 for the boat docked in Sausalito from my parents’ home near Sacramento, CA.  I’m fortunate to have my parents give me a ride so I don’t have to worry about leaving my car parked overnight.  We got into San Francisco at lunchtime and decided to stop at the Franciscan Restaurant near Fisherman’s Wharf.  The food was incredible and both Mom and Dad filled their cravings for bread bowls with clam chowder. Yummy!  We had an amazing view across the bay to Sausalito.  Next we headed for downtown Sausalito for dessert.  (If you haven’t gotten the clue yet this trip is all about great food and making friends.) It was beautiful with lots of little places to lose yourself and enjoy the view and watch people walking or riding by.  Cafe Tutti was a great little place for three waffle cones, laughs, and picturesque memories.  Then it was time to head to the boat!

Boat Tour and Unpacking

Permission to come Aboard?

Permission to come Aboard?, Picture by Karen Romito

I met Kaitlin Graiff and Erik Larson on board when I arrived.  She is the (Acting) Research Coordinator for the Cordell Bank National Marine Sanctuary and he is the Captain of the R/V Fulmar.  They were both so welcoming and gave us all the grand tour.  It only consisted of about fifty steps, but who’s counting.  We saw the wheelhouse (where you drive the boat), the bunk rooms (where you sleep on the boat), the galley (where you eat on the boat), the head (where you handle business on the boat), the fly bridge (where you observe animals), and the rear deck (where you use equipment to study the ocean).  I know that’s lots to remember, but it’s smaller than it sounds with cozy little places to have a snack or a cat nap.  Before I said my goodbyes Mom made me take a picture with all of my gear.  Thanks Mom!

Then it was time to unpack.  I chose the top bunk on the starboard side of the boat.  Now the important thing to remember is to duck when you get the top bunk.  There is almost no head room so duck early and often.  I’ve hit my head three times already.

Scientists Arrive

While Kaitlin, Erik, and I were getting to know each other, two more scientists arrived throughout the evening before dinner.  They were bringing the two most important parts of our cruise: the food and the equipment.  Jaime Jahncke, California Current Director for PRBO Conservation Science arrived first.  His name and title sound very official, but he is the most charismatic person you’ll meet.  He loves to joke around and have a good time while working to preserve and manage wildlife.  Last to arrive Monday night was Jan Roletto, Research Coordinator at Gulf of the Farallones National Marine Sanctuary.  Jan is the lead scientist on the cruise, mother hen to everyone.  She brought the most important thing for the trip: FOOD.  We have chips, nuts, crackers, chocolate covered everything, every soda drink imaginable, and more!  Did I mention that this trip is all about the food :).

Day 2, July 24, 2012

Early Risers

Survival Suit

Me in Survival Suit during Safety Drill

I am usually a morning person, but this morning I could have stayed in bed a little longer.  The crew, scientists, and I woke up between 5 and 6 AM to welcome five more people onto the boat.  Daniel Hossfeld, Intern at Cordell Bank National Marine Sanctuary; Carol Keiper, Marine Mammal and Seabird Observer; Kirsten Lindquist, Ecosystem Monitoring Manager at Farallones Marine Sanctuary Association; Kerri Beeker, Major and Planned Gifts Officer at PRBO Conservation Science; and Caitlin Byrnes, National Marine Sanctuary Foundation.  Once everyone was on board and the gear was stowed and tied down we headed for the first transect line of the day.

Science and Technology Log

The Work

This section has a little more science and technical language, but just bear with me because I want you to understand what we’re doing out here.  Applied California Current Ecosystem Study (ACCESS) has been monitoring 30 different transect lines (hot spots for animal activity) in Cordell Bank, Gulf of the Farallones, and Monterey Bay National Marine Sanctuaries.  Today we completed four transects: Nearshore 5, Offshore 5, Offshore 7, and Nearshore 7.  On these four lines the scientists observed the wildlife – documenting seabirds and marine mammals.  They use a laptop with Global Positioning System (GPS) tracking and software that shows a map of the area we are studying with the transect lines.  The software uses codes to name birds and marine mammals: a number to code for behavior, a number for zone (ie. distance from boat), and a true bearing direction from the bow (front) of the boat.  The birds are identified using the American Ornithology Union (AOU), which is a four letter code based on the bird’s common name (ie. Common Murre, COMU).  The birds are observed at a max distance of 200 meters from the boat.  Marine mammals are also given a four letter code based on the common name of the animal (ie. Blue Whale: BLWH).

Another important aspect of the observation is continually updating environmental conditions.  Observers describe visibility, swell height of the waves, wind speed and direction, cloud cover, and an overall rating for the conditions for that time.  Click on the Title below for an example of their codes.

What did I do Today?!

My bunk

Napping while recovering from nausea.
Good times!

Well, to sum it up in a word: relax!  I was able to get used to being at sea and rest a little from a stressful week of preparation for this trip.  I was nauseous this morning for about six hours, but I was able to overcome by sitting still and gazing at the horizon.  I must admit that being around a bunch of different food while feeling nauseous is not fun and makes you feel worse.  When I finally felt better I was able to have lots of great conversations with Kerri and Caitlin.  They are doing so much to support this ACCESS cruise and awareness about conservation of ecosystems.  It was nice to get a picture of the non-profit side of these issues.  I was also able to see some Pacific white sided dolphins bow riding and two humpback whales about 20 feet off the bow.  They popped up in front of the boat and we had to slow down so we didn’t interrupt them.

The first two days have been amazing and I can’t wait to see what we’re going to do next.  Tomorrow, we’ll be completing transect line 6.  You’ll  notice that there are black dots on the map.  Those indicate places where I will work with Kaitlin to get water column samples and samples of krill and zooplankton.

Here I am!

Greetings from Monterey, CA!  My name is Talia Romito and I teach Physics and Biology at Trinity Christian High School in Monterey, CA.  The upcoming school year will be my first year as a Warrior and I am really looking forward to it.  The students and staff are amazing and I hope to make a lot of new friends.

I applied to the NOAA Teacher At Sea program so I could get a first hand look at how scientists gather data to better understand the Earth’s environment, and more specifically conserve and protect the plentiful resources our oceans have to offer.

R/V FulmarOn my voyage I will be joining the crew and scientists aboard the Research Vessel (R/V) Fulmar.  Click the name of the ship  to find out more about this amazing vessel and the work it allows NOAA to accomplish with the help of the crew and scientists.  We will be monitoring the ecosystems in the Cordell Bank National Marine Sanctuary.

Cordel Bank National Marine Sanctuary

The Cordell Bank National Marine Sanctuary is collaborating with the PRBO (Point Reyes Bird Observatory) Conservation Science and the Gulf of the Farallones National Marine Sanctuary in a monitoring effort called ACCESS (Applied Califronia Current Ecosystem Studies).

This monitoring program is amazing and I’m so excited to be a part of this work.  I’ve been preparing for a few months to go on this cruise; everything from a very comprehensive online training to increasing my daily workout routine to ensure I am well prepared for the adventure ahead.  The next time you hear from me I’ll be onboard the R/V Fulmar in the Cordell Bank and Gulf of the Farallones National Marine Sanctuaries.  I plan to create some awesome lesson plans from my experience to teach students about what oceanography is all about! Cheers!

Science and Technology Log

Welcome to the July 2011 Applied California Current Ecosystem Studies  six-day survey of the Gulf of the Farallones National Marine Sanctuary and the  Cordell Bank National Marine Sanctuary.  The purpose of this survey was  to find out if there were any biotic or abiotic changes happening in the sanctuaries. Prior to the trip, transect lines

This map shows transect lines in the areas we are studying in the sanctuaries.

were drawn on a map.  The science team onboard the R/V Fulmar planned to survey as many of the lines as was possible.  While following the transect lines, all animal sightings were recorded.  Once the data is collected, the scientists can compare the 2011 survey results to other years of data. What questions do you think a marine biologist might have while surveying the organisms in the marine sanctuary?  What might motivate an organization to send scientist on a survey such as this?


R/V Fulmar

R/V Fulmar

The vessel we boarded was the R/V Fulmar .  If you check the website you will see it is a survey machine!  For this cruise there were seven of us on the science team and two crew – the captain and the mate.   What features make this vessel a good one for ocean surveys?

Prior to disembarking, the crew and scientists frequently checked the conditions of the ocean in order to determine if the survey could be safely conducted. They used a computer on board to check the conditions from NOAA websites.  Another website was  real time buoy data . The computer indicated that the ocean was going to be very active on our first two days with 10-foot swells. It felt like we were in a washing machine.  Needless to say a few of us were feeling sea sick!  It was quite a humbling experience yet it bonded us too.  What remedies are there for sea sickness?  What would you do to prepare yourself for a trip on the R/V Fulmar?

abiotic: nonliving

The science team was divided into two groups: those working on the flying bridge at the bow or front of the vessel and those working on the back deck with nets.  On the flying bridge there were three observers, two on either

end, the port (left) and the starboard (right),  who would spot all marine mammals (Carol Keiper and Jan Roletto).  An ornithologist on board would identify birds (Sophie Webb).  The other member (Jaime Jahncke) recorded what the animal was, where it was, how many there were and what the organisms were doing.  Sometimes there was a lot going on at one time and they would use a second recorder (Kaitlin Graiff) temporarily to document all the animals. The data is always gathered in this way.  Those who were not observers were allowed to watch but not to assist the observers.  Can you think of a reason why?

They spotted 50 whales: 10 blues and 40 humpbacks; some breaching, some tail lobbing.  We documented 16 different species of birds including the Tufted Puffin, Cassin’s Auklet, Northern Fulmar, Pink-footed Shearwater, Sooty Shearwater,  Western Gull, Heermann’s Gull, Fork-tailed Storm-Petrel, Ashy Storm-Petrel, Brown Pelican, Brandt’s Cormorant, Common MurreElegant Tern, Pigeon Guillemot, Red-necked Phalarope and Black-footed Albatross. (Sophie Webb, the ornithologist on board took these shots). Each of these animals are predators and some of them were found in the thousands out in the sanctuaries.  What would be possible prey for all of these animals?

Having many different species living in an area is called biological diversity.  Diversity is a measure of health in an ecosystem, the more different species that are supported, the better the ecosystem can deal with environmental change.  What would be some possible environmental changes that the organisms in this ecosystem might be experiencing?  

Many of these animals are pelagic, which means they live their entire life without visiting a mainland.  Many of them are predatory on the fish and zooplankton living in the ocean.   Where does the energy to support such large numbers of predatory animals come from?   What organisms are at the bottom of the food chains that support these animals?

Science and Technology Log
We left Half Moon Bay at 0700 (7:00 am) to survey line 10. We traveled out to about 30 miles offshore then deployed the Tucker trawl.

Tucker Trawl

Tucker Trawl

When the team deploys the Tucker trawl the goal is to collect krill. They are relying on the echo‐sounder to determine where the krill are located in the water column. The echo‐sounder sends out sound waves that bounce off objects in the water and works much like a sophisticated fish finder. Dolphins hunt for their prey in much the same way. A computer connected to the echo‐sounder is used to display the image of the water column as the sound waves travel back to the boat. By reading the colors on the screen the team can determine the depth of krill.

The scientists send weights (called messengers) down a cable that is attached to the Tucker trawl as it is towed behind the boat. Once the messenger reaches the end of the line where the net is located, it triggers one of the three nets to close. Triggering the nets this way allows for the researchers to sample zooplankton at three different depths.

Science and Technology Log

Imagine standing next to an animal that is 12 times the length of you. It happened to us aboard the R/V Fulmar. Today, humpback whales where milling around our 67 foot boat. We were able to take some great pictures and some video.

humpback whale

Humpback Whale

The humpback consumes krill and small fish. Krill is a small (1.5 inches in average length) shrimp like organism. Krill is a primary consumer. They feed on phytoplankton. Phytoplankton is a producer in the ocean ecosystem. These small “plants” absorb light energy from the sun and through the process of photosynthesis they make energy for the consumers to ingest and use. Krill feed on this phytoplankton at night just below the surface of the ocean. During the day the krill swim to deeper parts of the water column to avoid predators like the humpback whale.

Other organisms observed today, included a pod of Pacific white‐sided dolphins, a Tufted puffin, and South Polar Skuas.
