At the edge of Hudson Bay, polar bears roam near Churchill, where the tundra, boreal forest and ocean meet—and where global warming is rapidly reshaping Arctic ecosystems. Rising air and sea temperatures are thawing permafrost, shifting wetlands and pushing trees into once-open ground, changing how wild animals—including polar bears—move and feed across the region. Join scientists on land and water to track these transformations as we explore one of the most dynamic environments on Earth. Survey the tundra landscape by Polar Rover and helicopter as we keep an eye out for polar bears, ride behind a dog team, learn about northern cultures, and discover why the impacts of a changing Arctic climate matter far beyond Churchill.
Research at a Glance
Your Role in Research
The Research Focus
Contribute to hands-on field research focused on permafrost thaw, depth of the active soil layer atop the permafrost, and shifting treelines in one of the fastest-warming regions on Earth
What You'll Do
Join scientists to measure permafrost thaw and study the advancing treeline, tracking changes within the Arctic ecosystem with implications for wildlife and humans alike.
Why It Matters
Churchill lies at the nexus of ocean, tundra and boreal forest, revealing impacts of climate change in real time that help scientists understand Arctic ecosystem shifts globally.
Meet Your Lead Scientist
LeeAnn Fishback, Ph.D.
Dr. LeeAnn Fishback has spent nearly three decades studying freshwater systems across Arctic and subarctic regions, focusing on how climate change is reshaping northern lakes and ponds. Based in Churchill, she leads long-term research that reveals how rapidly changing conditions are transforming the North.
Contribute to Arctic Climate Science at Treeline
Measure permafrost thaw, active soil layer depth and document the advance of forest into tundra, contributing data to understand rapid changes on Arctic ecosystems
Search for Polar Bears on the Autumn Tundra
