Seabird responses to a changing Bering Sea

The eastern Bering Sea is well known for its spatial and temporal variability. Significant inter-annual changes in abundance of zooplankton and forage fish are related to the timing of sea-ice retreat. In this Theme Section, studies explore how different species of seabirds inhabiting the region respond to contrasting patterns of spring sea-ice retreat and summer temperatures. Data from the pelagic realm explore climate-linked variability in the abundance of seabirds since the mid-1970s, and the responses of seabird distributions to years with early and late sea-ice retreat. Colony-based studies, relying on bird-borne data-loggers and physiological parameters, examine how long-term changes in the foraging and migratory behavior of individuals during cold and warm years may affect birds breeding on the Pribilof Islands. A unique aspect of this Theme Section is the availability of both colony-based and pelagic studies of seabirds that overlap in space and time. This body of work aims to provide an overview of seabird responses to oceanographic variability in the eastern Bering Sea, spanning a period of 100 years and an immense oceanographic region.
