All I can say about my NOAA Teacher at Sea experience is WOW- what an incredible experience.   Thank you to everyone at the NOAA Teacher at Sea program, the crew of the NOAA Ship Bell M. Shimada, the ACCESS research scientists on-board and the staff of the Greater Farallones and Cordell Bank National Marine Sanctuaries.     I’d particularly like to thank Dr. Jaime Jahncke for teaching me how to collect and process zooplanton samples using the Tucker Trawler and enabling me to become a trusted member of his research team.

During the cruise, I learned so much about the work of oceanographers, marine biologists and ecologists.  I’ve sailed in these waters in my own sail boat many times but I’ve never seen the sanctuaries through the lens of a researcher.  The care and attention to detail taken during marine wildlife observations and the collection of  zooplankton and phytoplankton samples throughout the water column reveals an incredibly rich and abundant ecosystem.  The data collected will be shared with scientists around the world and helps us better understand and manage the health of our oceans.

The experience has given me lots of great ideas for lessons that I think will engage students and get them excited about knowing more about the ocean. I can hardly wait for the next school year to start so that I can share this amazing experience with students and facilitate learning experiences to inspire future scientists.

Here are some great wildlife pictures that I wanted to share earlier but the connectivity on the vessel was really limited and I wasn’t able to post them.

Science and Technology Log

After leaving San Francisco Bay, yesterday we headed west and spent the day getting our “sea legs” and collecting observations of marine mammals and birds in the Greater Farallones National Marine Sanctuary waters.    We began collecting data around 1300 hrs from 37° 47′ 52.4“ N  122° 53’ 31.2” W and headed west towards the continental shelf break approximately 30 miles off shore.

Throughout the day we followed a series of predetermined tracks (referred to as transects) and collected counts of the abundant life thriving in the sanctuary.   We saw numerous Blue Whales, Fin Whales, Humpbacks and dolphins.   We also had a sighting of a strange prehistoric looking fish called a Mola mola (common name: Ocean Sunfish).   Mola Mola are the largest bony fish in the world and are playfully described small dinner plates and can grow to as large as a smart car.    They tend to live in deep water so seeing one at the surface is a real treat.   Their distinctive dorsal and ventral fins are quite long and their pectoral fins (the ones on the sides) are quite short and stubby.  They dine on jelly fish and need to eat a lot in order to develop and sustain their substantial bulk. Members of the ACCESS survey team have observed Mola slurping up Velella velella ( common name: Sea Raft) a type of free-floating hydrozoan that lives on the ocean surface.

My free time has been getting accustomed to being at sea again and getting to know my new colleagues.   The internet onboard is very limited and we have 40 users sharing it so getting blogs out is proving to be more challenging than I’d anticipated

Did You Know?

The terms “port” and “starboard” are used as to indicate the left and right sides of a ship. “Starboard comes from the Old English “steorbord”, meaning the side on which the ship is steered. Before rudders (which are located in the centerline), early ships had a steering oar and because most people are right handed it was located on the right hand side of the ship.  Because the steering oar needed to be out of the way when docking the opposite side of the boat traditionally was the side that was closest to the pier. Hence “port” refers to the left side of a ship if you are looking towards the front of the ship.  The front of a ship is called a “bow”.

A bit about the ship-  NOAA ship Bell M Shimada was commissioned by NOAA in 2010.   Her home Port is Newport Oregon, and she supports research activities on the West Coast of the United States.   She’s 209 feet long and weighs 2479 tons, has a cruising range of 13,800 miles and travels at 11 knots (12.6 mph).  Shimada is an impressive vessel and is uniquely capable of conducting fisheries, oceanographic research and hydrographic studies.  She is considered to be one of the most advanced fisheries research vessels in the world.   Her stern looks very similar to a commercial fishing vessel and is capable of deploying large trawling nets for research to depths of 3,500 meters (11,483 feet).   Shimada uses specialized acoustic quieting technology developed by the U.S. Navy to monitor fish populations without disturbing the fish and altering their behavior.  She also has a Scientific Sonar System, used to measure the biomass of fish populations in a survey area.  Her acoustic profiling system enables scientists to gather data on ocean currents and provides information on the content of the water column and the topography of the seafloor.  In addition to sending out smaller sampling nets, longlines, and fish traps she can also deploy instruments to measure the electrical conductivity (used to determine salinity), temperature, depth (CTD) and chlorophyll fluorescence of sea water.  You can learn more about the ship here: https://www.omao.noaa.gov/learn/marine-operations/ships/bell-m-shimada/about

It’s a delight and an honor to be part of the ACCESS research team on NOAA ship Bell M. Shimada.

Weather Observations: Rainy

Here I am, three weeks deep in a new school year, and it’s hard to believe that less than a month ago I was spotting whales while on marine mammal watch and laughing at dolphins that were jumping in our wake. I feel like telling my students, “I had a really weird dream this summer where I was a marine biologist and did all kinds of crazy science stuff.”

IMG_20170817_103950017_HDR

Me on marine mammal watch

If it was a dream, it certainly was a good one! Well, except for the part when I was seasick. That was a bit more of a nightmare, but let’s not talk about that again. It all turned out okay, right?

I didn’t know what to expect when signing on with the Teacher at Sea program, and I’m amazed at how much I learned in such a short period of time. First of all, I learned a lot about marine science. I learned how to differentiate between different types of jellyfish, I learned what a pyrosome is and why they’re so intriguing, I learned that phytoplankton are way cooler than I thought they were, and I can now spot a hake in any mess of fish (and dissect them faster than almost anyone reading this).

I also learned a lot about ship life. I learned how to ride an exercise bike while also rocking side to side.  I learned that Joao makes the best salsa known to mankind. I learned that everything – everything – needs to be secured or it’s going to roll around at night and annoy you to pieces. I even learned how to walk down a hallway in rocky seas without bumping into walls like a pinball.

Well, okay. I never really mastered that one. But I learned the other things!

Beyond the science and life aboard a ship, I met some of the coolest people. Julia, our chief scientist, was a great example of what good leadership looks like. She challenged us, looked out for each of us, and always cheered us on. I’m excited to take what I learned from her back to the classroom. Tracie, our Harmful Algal Bloom specialist, taught me that even the most “boring” things are fascinating when someone is truly passionate about them (“boring” is in quotes because I can’t call phytoplankton boring anymore. And zooplankton? Whoa. That stuff is crazy).

Lance taught me that people are always surprising – his innovative ways for dissecting fish were far from what I expected. Also, Tim owns alpacas. I didn’t see that one coming. It’s the surprising parts of people that make them so fun, and it’s probably why our team worked so well together on this voyage.

I can’t wait to bring all of this back to my classroom, specifically to my math class. My students have already been asking me lots of questions about my life at sea, and I’m excited to take them on my “virtual voyage.” This is going to be a unit in my eighth and ninth grade math classes where I show them different ways math was used aboard the ship. I’ll have pictures and accompanying story problems for the students to figure out. They’ll try to get the same calculations that the professionals did, and then we’ll compare data. For example, did you know that the NOAA Corps officers still use an old-fashioned compass and protractor to track our locations while at sea? They obviously have computerized methods as well, but the paper-and-pencil methods serve as a backup in case one was ever needed. My students will have fun using these on maps of my locations.

They’ll also get a chance to use some of the data the scientists took, and they’ll see if they draw the same conclusions the NOAA scientists did. A few of our team were measuring pyrosomes, so I’ll have my students look at some pyrosome data and see if they get the correct average size of the pyrosome sample we collected. We’ll discuss the implications of what would happen if scientists got their math wrong while processing data.

I am so excited to bring lots of real-life examples to my math classroom. As I always tell my students, “Math and science are married.” I hope that these math units will not only strengthen my students’ math skills, but will spark an interest in science as well.

This was an amazing opportunity that I will remember for the rest of my life. I am so thankful to NOAA and the Teacher at Sea program for providing this for me and for teachers around the country. My students will certainly benefit, and I have already benefited personally in multiple ways. To any teachers reading this who are considering applying for this program – DO IT. You won’t regret it.

Science and Technology Log

After spending a few days observing what happens in the Acoustics lab and listening to our Chief Scientist Rebecca (RT) Thomas and acoustician Julia Clemons brainstorm aloud, I had one overriding question…”How do you decide when to fish?”

I asked RT this question and it is a multi-factored decision for sure, but seems like the decision could be broken down into 3 parts: what we see, what we know and what is currently happening.

What they see when deciding to fish or not is an echogram created by three acoustic sounders on the ship that send out 3 different frequency wavelengths. The image shows a relatively low frequency 18 kHz, 38 kHz, and a longer wavelength of 120 kHz. Keep in mind that sound travels faster in water than on land so this is a great way to gather information while being minimally invasive to the marine environment.

Bridge of Bell M. Shimada. The 3 screens we watch during a AWT trawl for Hake.

The backscatter, sound that scatters off of an object or its echo, on the echogram is what they look at to determine what marine life is on the transect we are scouting. As the sound wave bounces off of material in the ocean be it rock, flora or fauna it will create a spot or colored pixel on the echogram. Hake has a particular “look” of backscatter. When the echogram shows this particular hake sign we move in the direction of fishing.

Of course they only know what “hake sign” is because of gathering evidence throughout the course of this multi-year survey. During this survey they have created a huge reference database of hake sign and sign of other integral species to the hake’s environment, for example Euphausiid sp., one of the hake’s favorite food. RT and Julia have both interpreted many echograms and fished to confirm the identity the organisms that created the sign.  They are able to rule out images on the echogram until they find the backscatter that most resembles what they have historically experienced as hake.

The third part of this decision making process is the most variable…what is currently happening. As the boat travels and the sounders are sending out the trio of wavelengths an image of the ocean shelf is created. The scientists are able to see topography and measure the depths of the shelf’s different contours. The Shimada is a 209 foot long boat weighing over 2,400 tons. When deciding to trawl for hake that we suspect are present because of backscatter sign in the echogram the scientists and Commanding Officer always consider the depth to bottom, contours, wind and the maneuverability of the ship. Deploying the Aleutian Wing Trawl (AWT) net to catch hake is a task that involves cooperation and communication between the deck crew, Boatswain, bridge officers and the Chief Scientist. When RT sees a sign on the echogram that she wants to fish, she and Commanding Officer Kunicki quickly discuss the approach, wind direction and depth to get an idea on how the net will be affected and how close the ship can get to the exact sign that she wants to sample.

This is my bare bones description of the process that goes into deciding when to fish on Leg 5 of the Pacific Hake Survey. Stay tuned to see what we learn from comparing the echogram of sign to the actual yield from the AWT fishing net.

Personal Log

This ship is filled with kind, creative and industrious people. I am reminded of this constantly and appreciate this often. To me it is astounding to consider all the work and thought that is involved in a fifteen-day research survey at sea. This is a science survey so there are specific tools, computer programs and labs that must run well. To me, coming in with a science focus, this is most obvious. What I am blown away by are all of the additional layers that work together to make science even possible on this successful voyage. There are several teams at play: engineering, technology, deck, science and the bridge officers. Engineers are constantly maintaining engines, generators (this ship has 4), plumbing, ventilation and so much more. I had a tour today with Engineering Chief Sabrina Taraboletti that I am still trying to process through.

Technology is handled by one person on this ship. He maintains and trouble shoots computers in the acoustics lab, the bridge, the chemical lab and even found time to help maximize signal for the Fantasy Football draft. The deck crew is as versatile as anyone on this ship. We have two types of nets that we fish with. The deck crew is responsible for getting the nets out to fish and back in with the catch. Way easier said than done when we are talking about over a ton of weight with net, camera, chain, and doors. On top of all their other responsibilities many of the men in the deck crew have been helping out in the galley (kitchen) on this leg of the hake survey. Larry is the chief steward (chef) on board this leg and he typically has someone working with him but not on this leg of the Survey. So in addition to working their 12 hour shift, many of the deck crew have been working with Larry to prep food, clean up the mess (dining area), do dishes or even create their own personal specialties for dinner. We have been spoiled by Matt’s rockfish, Joao’s fresh salsa and soups and our Operations Officer Doug’s amazing BBQ. Liz and I even got to help out and make some donuts with Larry. Eating is great on the Shimada!

Liz & OCB makin the donuts

Liz and OCB making the donuts – thanks for the lesson Larry.

The Shimada team is rounded out with the bridge crew made up of 4 officers. The officers on a NOAA ship have a foundation of science knowledge and extensive nautical training. Before we go fishing I get to participate in the marine mammal watch up in the bridge. As I look for whales, dolphins and other marine mammals near the boat I can listen to the Captain and officers working their magic. We have had an incredibly smooth trip thus far which I credit to our Officers and of course Mother Nature.

 

 

 

 

 

 

 

 

Did You Know?

our Viperfish for blog

Who is this?

Crazy cool catch of the day…can you figure out what type of fish this is?

Here is a clue…they have specially adapted cells called photocytes that create light producing organs called photophores.  The photophores run along the sides of the fish and help them to lure prey and attract mates.

 

Answer:

This is a Viperfish.

Viperfish live in the deep ocean and migrate vertically as the day goes on in order to catch prey. They typically live around 1,500m (4,921 ft) and in the night will end up around 600m (1,969 ft) at night. This particular fish appears to have photophores along its mouth but it is difficult to be 100% sure from this specimen.

Science and Technology Log

We have not started fishing yet because we are heading to our first transect off the western coast of the Haida Gwaii archipelago. I thought this would be a perfect time to introduce another research project that is gathering data on the Shimada. One of my roommates, Lynne Scamman, is on-board researching Hazardous Algal Blooms (HABs).

Lynne in Chem lab

Lynne Scamman running wet chemistry tests and identifying phytoplankton.

  1. What are Hazardous Algal Blooms?

They are large numbers of phytoplankton, either diatoms or dinoflagellates, who produce toxins. Phytoplankton are essential to the ecosystem because they produce half of the global oxygen. However under certain circumstances these organisms reproduce rapidly, skyrocketing the population, this is a bloom. Some of these phytoplankton produce toxins. When the populations are low the toxins aren’t a big deal. However, when a bloom of phytoplankton that produce toxins occurs there can be health concerns for organisms exposed to the toxins. We have to consider the marine food chain and something called bioaccumulation. Phytoplankton along with zooplankton create the base of the marine food web. Organisms who eat toxin producing phytoplankton retain the toxin in their body. Then any organism who eats them will also hold that toxin. You can see how the toxin would accumulate along the food chain and potentially hold serious side effects for organisms with high levels of toxin.

  1. Why is research being done on HABs?

HABs are becoming a problem for humans along the coasts and in the Great Lakes. Basically all of the factors that contribute to the increase in HABs are a product of human impact. Global climate change, increased nutrient pollution and global sea trade are all factors contributing to the rise in Hazardous Algal Blooms. We want to monitor so that eventually we will be able to predict when, where and why the HABs will occur.

  1. Why are YOU studying HABs?

One day I walked into my college biology lab and met a guest instructor who specializes in all things phytoplankton related. I was blown away by the complexity that some of these single celled organisms held. The professor shared a few species names and I started investigating. The species that grabbed my attention is called Nematadinium armatum. This organism has a rudimentary eye called a melanosome and nematocysts for hunting, again this is pretty impressive for an organism made of one cell. Once I learned about the variety in this microscopic world and how influential they were to the health of the entire ocean, I knew that I wanted to learn more.

Personal Log

I am still figuratively pinching myself every few hours at just how amazing this experience is to participate in first hand. Yesterday we left the dock of Port Angeles at 10am and the boat hasn’t slowed down since. We did drills to ensure that all aboard knew where to go in case of fire and if we needed to abandon ship. Part of the abandon ship drill is to make sure that everyone has and can get into their Immersion Suit aka “Gumby Suit.” This suit is amazing! This portion of the Pacific is quite cold and the Immersion suit would keep you warm and buoyant until a rescue can occur.

OCB Gumby

Trying on the Immersion suit.

After our drills several of the science crew went up to the Flying Bridge to look for marine mammals. We were cruising between Cape Flattery, Washington and Vancouver Island, British Columbia with high hopes of seeing activity. WOW, we lucked out. We spotted 17 Humpback whales, 2 Harbor porpoise and 2 Dall’s porpoise. We are also seeing several types of sea birds but I am still brushing up with the Sibley to id birds from this area.

Shimada Flags

Did You Know?

The island cluster that we are heading to had a name change at the end of 2009. What was formerly called Queen Charlotte Islands is now called Haida Gwaii. This name change came as part of a historic reconciliation between British Columbia and Haida nation. Haida Gwaii translated means “island of the people.”

Science and Technology Log:

I have yet to meet the scientists and crew of the Shimada so I have no first hand info to share.  However this is a great opportunity to introduce the main focus of this survey… Merluccius productus, Pacific Hake.

(photo courtesy of http://www.nmfs.noaa.gov/)

Pacific Hake is an important species to both humans and many species in the marine ecosystem off of the Pacific Northwest coast of both the United States and Canada.  There is a cooperative effort to manage these fish that involves the governments of both the U.S. and Canada, fisheries scientists and fisherman.  Such a collaboration and intentional effort  amongst so many groups is a great model and example for other issues at large.  Here is some background reading related to the Pacific Hake Survey.

Personal Log:

I have taught middle school science at Renfroe Middle School (RMS) in the City Schools of Decatur for 10 years.  Renfroe is full of wonderfully intelligent, thoughtful and supportive people – students and staff.  Currently, I work with 7th grade students as we explore ecology, evolution, genetics, cells and anatomy.  I am thrilled to have this adventure at sea to share with my students and friends.  I look forward to bringing back real-world research and developing curriculum that we can ALL benefit from.

As an inquisitive and adrenaline hungry person I love the combination of adventure and challenging work, so I am thinking that my time on the Bell M. Shimada may be about as ideal of a learning opportunity as I could imagine. In addition to being a classroom teacher at RMS, I also work as a Mentor in The Nature Conservancy’s Leaders in Environmental Action for the Future (LEAF) program. LEAF provides an opportunity for Mentors and Interns to spend an intensive month focused on all aspects of conservation. This program encourages all involved towards hands-on environmental stewardship experiences and to broaden the boundaries of our comfort zone.  For both my RMS students and LEAF mentees I take this Teacher At Sea opportunity to put into action the message that I often share with them…learning is a life long goal and risk-taking is a way to enhance the connection that you feel with the world.

I want to thank my colleagues and students for a heart warming send-off and I promise all plenty of awesome photos and updates to come.

Did you know?

According to Atlas Obscura, in 1914 the town of Port Angeles had such an issue with sewage flooding that they opted to raise one of the town’s main streets by 10-14 feet.  This engineering challenge was accomplished by moving soil from a neighboring hill completely by hand…no mechanical interventions.  To this day you can tour the underground areas and see store fronts frozen in time.  This lovely seaside town is where I will embark on my voyage.
