Three themes of ongoing research: forecasting polar bear and walrus population response to changing marine ecosystems; measuring wildlife population changes in the Arctic coastal plain, and wildlife communities in the boreal-Arctic transition zone.
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.
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.
Published and nonconfidential unpublished coal data from wells in Alaska. Includes well locations, depth and thickness of coal in well, formation type and name, and business administrative information such as permit numbers.
Changes in both the ocean and coastal ecosystems may have negative effects on sea otter populations in the coastal Northwest and Alaska. A study underway will examine these factors and the overall health of sea otter populations.
Accelerating loss of mass, weakening correlation with the Pacific Decadal Oscillation, and increasing mass turnover likely are the result of changes to warmer and drier climate conditions that are affecting three well-studied glaciers.
