NOAA Teacher at Sea
Soon to be aboard NOAA Ship Oscar Dyson
August 21 – September 2, 2017
Mission: Juvenile Walleye Pollock and Forage Fish Survey
Geographic Area of Cruise: Gulf of Alaska (near Kodiak)
Date: August 17, 2017
Weather Data: 30.5°C, cloudy, 78% humidity
Location: Baltimore, MD
It is hot and sticky here in Baltimore and I am looking forward to breathing in the crisp air in Alaska. I am also looking forward to being out on the water. As a Baltimore resident, I am able to spend time in the beautiful Chesapeake Bay. It is a great place to get out on a kayak and take in nature. I can’t wait to take this experience to the next level on the waters of the Gulf of Alaska. I try to go on at least one big adventure each year, and the Teacher at Sea experience definitely will fulfill this goal for 2017! I am also excited about all of the new things I will learn on this trip and I am looking forward to sharing these with my students. I teach STEM courses to students who attend online school. I have seen how connecting scientific experiences and data with students can spark their interest in STEM fields. I am very excited to have the opportunity to use this experience to engage students in scientific activities and discussions.
Science and Technology Log
This mission will take place on the NOAA Ship Oscar Dyson, which has its home port in Kodiak, Alaska. From Kodiak we will move through the waters surrounding Kodiak Island and eastward into the Gulf of Alaska. The scientific team will be studying populations of walleye pollock and zooplankton in these waters. The mission will be conducted in two parts. I will be aboard for Leg 1 of the mission. Leg 2 will begin shortly after we return to port on September 2nd. The map below show all of the sampling locations that will be visited during this mission. Leg 1 sampling locations are indicated by red dots. At each location, a variety of sampling will take place. From what I have learned about the mission, it looks like we will be using several different trawls to collect samples. We will then use a variety of methods to identify species and collect data once the samples are onboard.
The Oscar Dyson is described as “one of the most technologically advanced fisheries survey vessels in the world.” From what I see on the NOAA website, it seems to have an impressive amount of scientific equipment onboard. It has a wet lab, dry lab, computer lab, biology lab and hydrology lab. It also has a wide array of data collection gear and mechanical equipment. I am looking forward to checking out all of this equipment for myself and learning more about how it will be used.
This study will focus on collecting data on walleye pollock populations. This fish is a member of the cod family and lives primarily in the waters of the northern Pacific Ocean. As juveniles, this species feeds on krill and zooplankton. As they mature, they eat other fish, including juvenile pollock! Many marine species rely on populations of these fish as a food source in the Gulf of Alaska. Humans also like to eat pollock. It is sold as fillets, but is also used in fish fingers and to make imitation crab meat. Pollock fillets are becoming more popular as cod and haddock populations become overfished. Pollock populations have fluctuated over the years, but are not currently overfished. The dotted line in the graph below shows population numbers in the Gulf of Alaska (GOA).
A scientist from the U.S. Fish and Wildlife Service will also be aboard the Oscar Dyson conducting a seabird observation study. She will work mainly from the bridge, keeping track of the different seabird species she sees as we move from one sampling location to the next.
I am excited about my upcoming adventure for many reasons. As an undergrad, I majored in Natural Resource Management. I went on to be a science teacher, but have always been interested in learning about findings from ecological studies. This experience will allow me to get an up close look at the technology and techniques used to conduct this kind of study. I am looking forward to being able to contribute to the team effort and learn new things to bring back to my students. I am also very excited to be aboard a ship off the coast of Alaska. A trip to Alaska has always been on my bucket list and I am looking forward to taking in the scenery and spotting marine mammals and seabirds. I am also hopeful that we will be able to see a partial solar eclipse from the water. I am bringing my sun viewers, just in case!
Did You Know?
It would take 88 hours to drive from Baltimore, MD to Kodiak, AK.

I’m so excited for you Amanda! I hope you are having a great trip so far!
All the best,
