Landscapes of interwoven wetlands and uplands offer a rich set of ecosystem goods and services. Changes in climate and land use can affect the value of those services. We study these areas to understand how they may be changing.
The Arctic is warming faster than other regions of the world due to positive climate feedbacks associated with loss of snow and ice. The USGS has modeled the future responses of polar bear and Pacific walrus populations to this environmental change.
New synoptic data from samples collected in the Arctic Ocean and insights into the patterns and extent of ocean acidification. This foundational geochemical information will help us to understand potential risks to Arctic resources.
