Beaver Engineering: Tracking a New Disturbance in the Arctic
Research on North American beaver (Castor canadensis) engineering in the Arctic has made great strides in recent years, but most of the work lies ahead. Over the last several decades, people in remote Alaska communities have observed an influx of beavers.
Ocean Acidification
The uptake of anthropogenic carbon dioxide (CO2) causes a cascade of chemical reactions that decreases ocean pH and carbonate ion concentrations, a process known as ocean acidification (OA).
River Discharge
Arctic river discharge is a key indicator reflecting changes in the hydrologic cycle associated with widespread environmental change in the Arctic. It is the most accurately measured component of the Arctic water cycle.
2020 Foreign Marine Debris Event—Bering Strait
During 2020, the Bering Strait region of Alaska experienced a marine debris event that brought garbage ashore that was different from the types and amount typically observed.
Glacier and Permafrost Hazards
We focus on hazards related to glaciers and permafrost and define hazard as the potential occurrence of a natural physical process that may adversely impact human or ecological systems.
The Changing Arctic Marine Soundscape
In the global ocean, the combination of naturally occurring sounds, including those from wind, waves, underwater earthquakes, and marine animals, make up the underwater ‘soundscape.’
The Impact of COVID-19 on Food Access for Alaska Natives in 2020
The COVID-19 pandemic has exacerbated existing challenges for Alaska Natives in accessing traditional and store-bought foods.
About Arctic Report Card 2021
The Arctic Report Card (hereafter ‘ARC’) has been issued annually since 2006. It is a timely and peer-reviewed source for clear, reliable and concise environmental information on the current state of different components of the Arctic environmental system relative to historical records. The ARC is intended for a wide audience, including scientists, teachers, students, decision-makers, policy-makers, and the general public interested in the Arctic environment and science.
