A Very Big Dead Zone

Dead zones are hypoxic (low-oxygen) areas in the world's oceans and large lakes, caused by excessive nutrient pollution from human activities coupled with other factors that deplete the oxygen required to support most marine life in bottom and near-bottom water. In the 1970s oceanographers began noting increased instances of dead zones. These occur near inhabited coastlines, where aquatic life is most concentrated. The vast middle portions of the oceans, which naturally have little life, are not considered dead zones. Scientists are expecting a very large dead zone in the Gulf of Mexico and a smaller than average hypoxic level in the Chesapeake Bay this year, based on several NOAA-supported forecast models. NOAA-supported modelers at the University of Michigan, Louisiana State University, and the Louisiana Universities Marine Consortium are forecasting that this year's Gulf of Mexico hypoxic dead zone will be between 7,286 and 8,561 square miles which could place it among the ten largest recorded. That would range from an area the size of Connecticut, Rhode Island and the District of Columbia combined on the low end to the New Jersey on the upper end. The high estimate would exceed the largest ever reported, 8,481 square miles in 2002.

Hawaii's Fishermen: Scapegoats for Forces Outside their Control

Climate change is affecting fisheries in the Western Pacific and around the world, but a host of other factors, including land use, are threatening fisheries and the health and integrity of marine ecosystems. Aiming for sustainable fisheries, marine policymakers, resource managers, fishermen and other stakeholders are increasingly looking to take a more holistic, integrated approach to fisheries management, as evidenced during the latest meeting of the Western Regional Fishery Management Council (WRFMC) meeting, which was held in Oahu. Often blamed for overexploiting fish stocks, local fishermen in Hawaii are keenly aware of external impacts on the health and integrity of marine ecosystems and fish populations. At the latest WRFMC meeting in Honolulu, they argued in support of taking a more comprehensive ecosystems management approach, specifically zooming in on how land use and associated runoff from cities, agriculture and industry are harming marine ecosystems and fisheries.
