Scientists discover new ocean current
Scientists at Georgia Tech have discovered a new climate pattern, the North Pacific Gyre Oscillation. This pattern explains, for the first time, changes in the water important in helping commercial fishermen understand fluctuations in the fish stock. They're also finding that as the Earth is warming, large fluctuations in these factors could help climatologists predict how oceans will respond in a warmer world. (2008-05-01)
