Long-term Arctic Lake Area Change: Reducing Uncertainty and Paving a New Path Forward

There are more lakes and ponds in the Arctic than anywhere else in the world. These lakes provide habitat for wildlife and support the subsistence activities of Indigenous communities. Arctic lakes are also an important component of the climate system. Changes in lake area could strengthen or reduce climate change feedbacks, depending on whether lakes expand or shrink. Previous research shows that climate change is causing Arctic lake area to change, but the overall trend is unclear. This project uses high-resolution satellite data to assess the direction and magnitude of surface water change in the Arctic.

The Power of Collaboration
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.

Connecting to the Classroom
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.

The Power of Collaboration
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.

A Day in the Life
An Unforgettable Adventure Begins As a high school science teacher, the invitation to join Macall Hock on an expedition to study the effects of a warming Arctic ecosystem on stream carbon cycling in Utqiagvik, Alaska, felt like stepping into a thrilling adventure. The beauty of the Arctic wilderness was a sight to behold, but the
