The Arctic Alaska outer continental shelf has lured explorers with its hints of oil riches and an open water season that is expanding as sea ice diminishes. But brutal physical and economic conditions confound easy development.Yereth Rosen

Supplies are ferried from the US Fish and Wildlife Service research boat R/V Tiglax to Buldir Island in the Aleutians during a trip from Adak Island to Attu Island on a week long research mission in southwestern Alaska, on Tuesday, June 2, 2015. Scientists on the R/V Tiglax conduct research in the Alaska Maritime National Wildlife Refuge.

Three hundred miles west of Adak, Buldir Island is the most isolated island in the Aleutian chain. It's also more ecologically intact, making it a magnet for seabirds -- and for a special breed of scientists willing to spend a summer alone researching them.Lauren Rosenthal
Bogoslof Island, the tip of a mostly submerged stratovolcano in the Aleutians, is only a few hundred years old. It's northern fur seal populations meanwhile is only a few decades old. But it's growing, a fact that's drawing marine mammal researchers.Molly Dischner
