We estimate mean volumes of 896 million barrels of oil and about 53 trillion cubic feet of nonassociated natural gas in conventional, undiscovered accumulations within this area, a reduction of our 2002 estimate due to new geologic information.
Published and nonconfidential unpublished coal data from wells in Alaska.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.
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.
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.
