Meet the Team
Teacher - Craig Kasemodel
Craig Kasemodel is a science and technology teacher at the Central Middle School of Science in Anchorage, Alaska. Mr. Kasemodel attended the University of Wisconsin-Madison and Montana State University and holds degrees in Economics, International Relations, and Fish & Wildlife Management, and spent several years conducting wildlife biology research in rural Alaska and Montana. Mr. Kasemodel enjoys teaching other teachers how to incorporate technology in their classrooms and introducing students to science. He is active with the ALISON Project and recently developed a freshwater science class for students to conduct water quality and stream assessments. In his spare time, he enjoys building computers and websites, fly-fishing, hiking, skiing, and spending time outdoors with his wife and chocolate lab. He is excited to be part of PolarTREC and to joined the crew on the Healy with the hope of increasing awareness of climate change and polar science.
Senior Outreach Manager - Nora Deans
Nora Deans is the Senior Outreach Manager for the North Pacific Research Board in Anchorage, Alaska. Nora joined the research team as an observer aboard the USCGC Healy. The North Pacific Research Board provided some funding for Craig Kasemodel to join the expediton.

Project Information
Where are They?
The team traveled on the USCGC Healy to a sampling area in the northern Bering Sea. The Bering Sea lies to the west of Alaska and to the east of Russia. The team departed from and returned to the port of Dutch Harbor, Alaska, which is in the Aleutian Islands. During the cruise they sampled the biologically diverse waters as they moved northward toward Saint Lawrence Island.
What are they Doing?
A diverse team of researchers participated in the first of three research cruises this spring and summer aboard the USCGC Healy in support of the Bering Sea Ecosystem Study (BEST) and the Bering Sea Integrated Ecosystem Research Program (BSIERP). Check out the logbook at http://bsierp.nprb.org/cruises/current.html
Scientists onboard the ship documented late winter ocean conditions, studying the biological communities found in sea ice, examining the early spring plankton bloom, and investigating light penetration through open water and ice cover. Additionally, researchers examined the benthic communities living on the seafloor as well as observed an important benthic predator, the walrus. The region of the Bering Sea where the team was working is biologically rich and supports highly productive ecological communities of bivalves, gastropods, and polychaetes. These benthic communities have been changing over the past several decades, perhaps as a result of competing fish species moving north as waters warm.
Vocabulary
- Benthic
- Biogeochemistry
- Bivalves
- Gastropods
- Icebreaker
- Polychaetes
Benthic organisms live on or in the bottom sediments of a sea or lake.
The study of processes in the natural environmental using interdisciplinary tools from biology, chemistry and geology.
A group of mollusks, typically with two-part symmetrical shells.
A group of mollusks that travel on a single, muscular foot and often secrete a one-piece shell for protection. Snails, slugs, limpets and abalones are all gastropods.
An icebreaker is a special purpose ship or boat designed to move and navigate through ice-covered waters.
A large and diverse group of segmented marine worms. All possess an array of bristles on their many leg-like parapodia.
