Arctic Coastal Plain Studies
The Arctic Coastal Plain (ACP) is a large region of low-lying, lake-rich land on the North Slope of Alaska. This region is underlain by thick ground ice, which is susceptible to erosion and thaw. These physical changes are likely to alter ecosystems by changing the availability of habitats and food resources upon which wildlife depends. Our studies on the ACP aim to understand the link between...
Arctic Boreal Vulnerability Experiment (ABoVE)
ABoVE: Vulnerability of inland waters and the aquatic carbon cycle to changing permafrost and climate across boreal northwestern North America.
Carbon released from thawing permafrost may fuel terrestrial and aquatic ecosystems or contribute to greenhouse gas emission, leading to a potential warming feedback and further thaw.

Counihan, Katrina; Bowen, Lizabeth; Ballachey, Brenda; Coletti, Heather A.; Hollman, Tuula; Pister, Benjamin; Wilson, Tammy L Effects of ocean climate on the length and condition of forage fish in the Gulf of Alaska
Climatic drivers of the size and body condition of forage fish in the North Pacific are poorly known. We hypothesized that length and condition of forage fish in the Gulf of Alaska (GoA) should vary in relation to ocean temperature on multiple scales. To test this hypothesis, we analyzed morphometric data for capelin (Mallotus catervarius) and...
