My whirlwind polar adventure is coming to an end. After a very short 10 days (ALL DAY as the sun has not set in Alaska since mid-May), I find myself spending my last few hours in town reflecting on my experience both with the people as well as the research I helped with, all while admiring the tundra. Polar STEAM brought me to Utqiaġvik in collaboration with Dr. Julia York from the University of Illinois. Dr. York’s post-doctoral work is investigating how Arctic fishes, specifically Iqalugaq (Boreogadus saida, Arctic Cod) and Uugaq (Eleginus gracilis, Saffron Cod), physiologically sense and adapt to the freeze thaw cycles that dominate the Arctic throughout the year. Unlike some of the Antarctic fishes that Dr. York focused on during her PhD, Arctic cod experience a wider range of temperatures throughout the year, from freezing ocean water (28.4°F; -2°C) in the winter to up to mid-40s°F during the summer. Fishes are the same temperature as their environment and environmental temperature fluctuation means that during times of the year fishes must either swim away from the freezing water or adapt mechanisms to keep from freezing.

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.
