Research Geochemist Renee Takesue combines geology and chemistry to shed light on how chemical components from natural and human-made sources make their way into coastal environments.
Climate Science Champions, Season 1: Vanessa von Biela, Research Fish Biologist
Detailed Description
Research Fish Biologist Vanessa von Biela investigates how heatwaves and other climate-driven stressors may affect Alaska’s spawning Pacific salmon in the future.
Salmon forms the lifeblood for many in Alaska. The state hosts all five Pacific salmon species; Alaskan salmon hold cultural, economic and ecological significance. One of the major climate factors affecting salmon in Alaska is the increasing occurrence of extreme heat events. A record-breaking heatwave and drought in 2019 caused stress and unprecedented mortality in Alaskan salmon, affecting adults on their way to spawning grounds. USGS researchers are trying to understand how heatwaves and other climate-driven stressors will affect Alaska’s spawning Pacific salmon into the future. While an event like the 2019 heatwave was devastating—fish that die before spawning don’t contribute to future generations—salmon in Alaska are resilient.

Fish and Aquatic Ecology
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...
