The US academic research vessel RV Neil Armstrong departed from Nuuk, Greenland in early October. On the first leg of our journey, the science team’s initial purpose was to collect water samples and previously deployed instruments along a line of moorings at the southern entrance to Baffin Bay, a gateway between the Arctic and the north Atlantic. This line stretches from Sisimiut, on the west side of Greenland, to just off Cape Dyer, near the Canadian coast.
Identifying Central and Peripheral Thermosensors in Eurythermal and Stenothermal Arctic Fishes
The Arctic Ocean is warming at a rate up to seven-fold the global average, endangering and shifting key subsistence and commercial fisheries. Fish populations are stressed by warming and simultaneously by ocean acidification and oxidation. This study aims to characterize the evolution of sensory proteins that integrate signals of warming, changing pH, and oxidation in the sensory systems of three species of Arctic and sub-Arctic fish: the Arctic cod (Boreogadus saida), saffron cod (Eleginus gracilis), and Atlantic cod (Gadus morhua). Studying the evolution of these sensory mechanisms will provide insight into the sensitivity and responses of fish to climate change but also help us understand these same proteins in humans which are major drug targets that underlie pain, inflammation, itch, and the sensation of heat and cold. During the course of this research, two undergraduates from underrepresented groups in science will be mentored through a summer research program and a K-12 lesson plan will be developed that combines the science from this project with Alaska Native science curricula and values and Next Generation Science Standards.

Our plane glides through the Endicott Mountains of the Brooks Range as we make our final descent into Anaqtuuvak. Accessible only by plane, Anaktuvuk Pass (“the place of caribou droppings”) is located 250 miles northwest of Fairbanks and is home to the only community of inland Iñupiat, Nunamiut, people [1]. Below, icy blue glaciers feed into a winding network of streams that snake through dense, green tundra and low-lying willows that line the banks of the Anaktuvuk River. From the air, the tundra is a verdant forest, but once on the ground the trees and shrubbery are no taller than 5-6 feet. The village stands out like a colorful flower within the greenery, blooming into view as we enter the valley. In Anaktuvuk, the roots of plants and people alike extend down into permafrost, the lifeblood of the ecosystem and holder of history.
In July 2024 I had the opportunity to visit Amy in person in Arizona. In the vlog of my trip, I share pictures of the work one of Amy’s colleagues is doing on a telescope that is going in a hot air balloon in Antarctica, we visit Kitt Peak Observatory, which is built on the tribal land of the Tohono Odham nation, and then Amy’s lab at the University of Arizona. You will also hear snippets of the songs I wrote for our Polar STEAM resource assignment.
As a high school science teacher, I’m always looking for ways to inspire my students with real-world science and deepen their understanding of our planet. The PolarSTEAM Educator Fellowship has been an extraordinary opportunity to merge my passion for polar environments with my teaching. Through this year-long virtual collaboration with T.J. Fudge, a research scientist at the University of Washington, I’ve been immersed in cutting-edge research on ice cores, allowing me to bring current polar science research to my students.
The Juneau Icefield is a group of interconnected glaciers just north of Juneau, Alaska that extends into British Columbia, Canada and covers an area the size of Rhode Island. Maybe you’ve heard of the Mendenhall Glacier? It is part of the Juneau Icefield! The Juneau Icefield Research Program (JIRP) has been collecting data on the icefield since 1948.
