Using remote sensing through the ice to determine how much water was in the Nome River in the winter.
Fish and aquatic habitats in Alaska support important commercial, sport, and subsistence fisheries and provide forage fish that support wildlife populations. The USGS Alaska Science Center conducts interdisciplinary research to inform local, state, federal, and international policy makers regarding conservation of fish, aquatic species, and their habitats. We work collaboratively with hydrologists, geologists and other biologists to study fish and aquatic systems in an ecosystem based framework. The goal of our current research effort is to improve our understanding of the biocomplexity, resilience, and function of aquatic ecosystems to better inform future predictions of fish and aquatic ecosystems as they respond to a changing environment.

Clipping a sheefish fin in the Selawik River
Biologists clip the tip of one of the ventral fins of a sheefish that is in a cradle in the Selawik River, Alaska. This study was collecting genetic samples to help find impacts of fine sediment on sheefish. The results were no impacts due to low amounts of sediments present.
