| Summary: | The North Atlantic Oscillation (NOA) appears to determine the location and strength of the Gulf Stream and Labrador Current, which in turn, determines conditions in places like the Gulf of Maine, acting like an Atlantic counterpart to "El Nino." Neal Pettigrew, an oceanographer at the University of Maine and chief scientist for the Gulf of Maine Observing System (GoMOOS), studies the phenomenom. He says a "modest 2001 NOA event" might have important fisheries implications in a year or two, including on the lobster fishery. With details on how climate changes are affecting Arctic wildlife.
