In a major stride toward understanding the rapidly transforming Arctic environment, the Frontiers Planet Prize has honored Suzanne Tank and her colleagues from the Arctic Great Rivers Observatory (ArcticGRO) as 2025 National Champions for Canada. Their groundbreaking research, published in Nature Geosciences, illuminates recent chemical trends in the major northern rivers that drain into the Arctic Ocean, revealing profound indications of widespread environmental change across the Arctic region. This recognition celebrates the sustained, multinational scientific effort that has meticulously tracked shifts in river chemistry, providing critical insights into the Arctic’s evolving land-ocean system amid accelerating climate change.

The Arctic Great Rivers Observatory represents one of the most extensive and enduring monitoring programs dedicated to large northern river systems. Established nearly two decades ago at the Marine Biological Laboratory (�ֲ���ý) in Woods Hole, ArcticGRO focuses on six major Arctic rivers: the Lena, Yenisey, Ob’, Mackenzie, Yukon, and Kolyma. .
