Hands-on Experiences for K-12 Teachers

Teacher at Sea opportunities consist of participating in NGA LTER science activities while sailing with researchers on our periodic cruises. Not only do teachers on our cruises actively participate in research activities, they also communicate the experience to their students and the general K-12 community via web-based logs (blogs) and videos.

Cruises last 2-3 weeks and occur every May and September, and in alternating years in July (next cruise in 2025). Most, if not all of these cruises, will include a berth for a teacher or informal educator. We particularly welcome Alaska-based educators.

NOAA Partnership

Since 2018, we’ve partnered with NOAA and offered our Teacher at Sea positions through their application process. This was paused due to the COVID-19 pandemic, but we are excited to announce that berths will be available in spring and fall 2024 through the NOAA Teacher at Sea program!

If you are interested in the 2024 season, the application is now live on their website. The application deadline is November 30, 2023. More information can be found at their FAQ, or you can reach out to Katie Gavenus to discuss more specifics of the NGA LTER Teacher at Sea opportunity.


Participating Teachers

Cara Nelson, Fall 2019

Cara Nelson was our NOAA Teacher at Sea for the Fall 2019 cruise. Ms. Nelson teaches oceanography and marine biology at Bartlett High School (BHS) in Anchorage School District. She has also lived and taught in Cordova, Alaska, in Prince William Sound, so she is familiar with our study environment.

Catherine Fuller, Summer 2019

Catherine Fuller was our NOAA Teacher at Sea for the Summer 2019 cruise. Ms. Fuller teaches 6th grade history at Iolani School in Honolulu, HI. As a crew member of the Polynesian Voyaging Society, she has voyaged on the Hokule’a, a replica of an ancient Hawaiian canoe. She ties really good knots.

Katie Gavenus, Spring 2019

Katie Gavenus was our NOAA Teacher at Sea for the Spring 2019 cruise. Ms. Gavenus coordinates education programs at the Center for Alaska Coastal Studies in Homer. CACS provides guided school field trips at their Peterson Bay Field Station and at the Kasitsna Bay Labs, as well as ship-based oceanography programs on Kachemak Bay. Ms. Gavenus has also been selected by the PolarTREC program to be the educator onboard a MOSAiC project cruise in Fall, 2019.

Mark Van Arsdale, Fall 2018

Mr. Van Arsdale joined us from Eagle River High School, Alaska, where he teaches AP Biology, Forensic Science, Oceanography, and Marine Biology. His participation was made possible though a new partnership with the NOAA Teacher at Sea program, which we hope will continue in the coming years.

Per Fosstveit, Summer 2018

Mr. Fosstveit joined us from Monroe Woodbury Middle School located in Central Valley, New York. He participated in Seward Line sampling, especially net tows, and kept a log for his class back home.

Michele Hoffman Trotter, Spring 2018
Michele Hoffman Trotter created an educational series of learning modules and interviews of scientists aboard R/V Sikuliaq. Schools in Alaska, California, Chicago, and Canada participated in her lessons.

Armada Program

In 2008 and 2009, teachers participated on Seward Line cruises via the ARMADA program at the University of Rhode Island (funded by the National Science Foundation). This program has since concluded. However, the at-sea logs of the teachers are still available.
