— In hypoxic zones of the Gulf of Mexico is projected to be larger than average this year, due to extreme flooding on the Mississippi River this spring, according to an annual forecast by a team NOAA-supported scientists from the Louisiana Universities Marine Consortium, Louisiana State University and the University of Michigan.
The forecast is based on Mississippi River nutrient compiled annually by the U.S. Geological Survey (USGS). Scientists are predicting the area could measure between the corporation and 9.421 square miles, or an area on the area around New Hampshire. The largest hypoxic zone intends to date occurred in 2002 and includes more than 8,400 square miles. On average over the past five years is about 6,000 square miles from water, a lot more than 1,900 square miles, which is the target goal set by the Gulf of Mexico / Mississippi River Watershed Nutrients Task Force.
This collaboration between NOAA and USGS and university scientists facilitates understanding between activities in the Mississippi River watershed and after exposure to the northern Gulf of Mexico. Long-term data sets on nutrient and degree of hypoxia zone improved forecast models used by management agencies to understand the nutrient reductions required to reduce the size of the hypoxic zone.
Hypoxia is due to excessive nutrient pollution, often from human activities such as agriculture that results in too little oxygen to support most marine life in bottom and near-bottom waters. Hypoxic zone off the coast of Louisiana and Texas forms each summer and threatens valuable commercial and recreational Gulf fisheries. In 2009, as the value of commercial fisheries in the Gulf was $ 629 million almost three million recreational fishers further participation of more than $ 1 billion in the Gulf economy with 22 million fishing trips. —Physics.org
