Baffin Bay Geological Survey has estimated that at least 13% of the world's undiscovered oil deposits and 30% of the world's undiscovered gas pockets are located in the Arctic, with the seas around Greenland potentially holding large amounts of natural gas and lesser amounts of crude oil and natural-gas liquids. Accordingly, the Greenland authorities have offered a large number of off-shore concessions for potential hydrocarbon (oil and gas) extraction. The largest concession-areas are located in seas west of Greenland; primarily in Baffin Bay and the Davis Strait, but with several smaller concessions in the Greenland Sea in the east also.

Baffin Island Canada goose, snow goose and brant goose (brent goose). Shore birds include the phalarope, various waders (commonly called sandpipers), murres including Brünnich's guillemot, and plovers. Three gull species also nest on Baffin Island: glaucous gull, herring gull and ivory gull. Long-range travellers include the Arctic tern, which migrates from Antarctica every spring. The variety of water birds that nest here include coots, loons, mallards, and many other duck species. Water species that visit Baffin Island in the summer are: Harp seals (or saddle-backed seals), which migrate from major breeding grounds off the coast of Labrador and the southeast coast of
