All Aboard the USCG Icebreaker HEALY
Cruising the Bering Sea - May, 2007
On the science goals of the expedition, Jackie writes: "Perhaps the most striking evidence of global climate change is decreased extent of arctic sea ice and recent studies indicate this is occurring now south of St. Lawrence Island (SLI) in the SLI polynya region (SLIP). Despite research on the consequences of sea-ice change for physical oceanography and weather, effects on arctic marine food webs from microbes to top predators are by comparison very poorly understood. This area is currently the sole wintering site of the world population of the benthic-feeding Spectacled Eider (SPEI), a principal top predator. Expansion of competing crab and fish predators as ice cover declines and the cold pool of bottom water contracts may affect food availability for the eiders."
