Loss of sea ice has increased ocean wave action, changing coastal habitats. For some geese this has been a positive change, increasing the amount of coastal area that supports vegetation the geese feed on.
Changes in Arctic sea ice and permafrost will likely affect populations of wildlife. Migratory birds such as loons rely on freshwater lakes in the Arctic for nesting and food supply; we are studying how their populations are affected by these changes.
Airborne electromagnetic surveying is used to estimate the character of the permafrost by measuring and monitoring the electrical resistivity, which is affected by lithology, temperature, water, and ice.
Long-term studies to better understand the effects of the eruption and the role of volcanism in structuring ecosystems in the Aleutian Islands, a volcano-dominated region with high natural resource values.
