Hypoxia in the Northern Gulf of Mexico by Virginia H. Dale download in iPad, ePub, pdf

Read the full press release for more information Exit. Turner, Louisiana State University. The oxygen depletion, referred to as hypoxia, begins in late spring, reaches a maximum in midsummer, and disappears in the fall. George Hallberg from the Cadmus Group, Dr. Otto Doering, Purdue University.

Each of the reports underwent extensive peer review by independent experts. This size is larger than the predicted range made in June as described below. It also documents the relative roles of natural and human-induced factors in determining the size and duration of the hypoxic zone.

Each spring as farmers

Flux and sources of nutrients in the Mississippi-Atchafalaya River Basin. Researchers suggest that heavy rains in June and high river discharges in July may provide an explanation for the larger zone measurement. Researchers suggest that the Mississippi River May discharge, which was well above average, provides an explanation for most of the large zone measurement. These six now completed reports are to provide the foundation for the final integrated assessment that will be used by the Task Force to evaluate alternative solutions and management strategies.

The second largest dead zone in the world is located in the U. The research teams were not established to conduct new research, but rather to analyze existing data and applied existing models of the watershed-gulf system. The decomposition process consumes oxygen and depletes the supply available to healthy marine life.

Each spring as farmers fertilize their lands preparing for crop season, rain washes fertilizer off the land and into streams and rivers. William Mitsch, Ohio State University. Excess nutrients that run off land or are piped as wastewater into rivers and coasts can stimulate an overgrowth of algae, which then sinks and decomposes in the water. Generally, excess nutrients lead to increased algal production and increased availability of organic carbon within an ecosystem, a process known as eutrophication.

The objective of Hypoxia Watch is to develop new near-real time data and map products using shipboard measurements of bottom-dissolved oxygen and disseminate them over the Internet.
