Large Dead Zone Found in Gulf of Mexico
(Hypoxia) Task Force target of less than 1,900 square miles--meaning nutrients from the Mississippi River watershed are continuing to affect the nation's coastal resources and habitats in the Gulf. The task force consists of five federal agencies, 12 states and the tribes within the Mississippi-Atchafalaya River Basin, and was established in 1997 to reduce and control hypoxia in the Gulf of Mexico. The largest Gulf dead zone ever recorded occurred in 2002, encompassing 8,481 square miles. The smallest recorded dead zone measured 15 square miles in 1988. The average size of the dead zone over the
Robotic Marine Vehicles: Meet the Anaconda-2
Recently, Swiftships Shipbuilders, LLC, in Morgan City, La., showcased the Anaconda-2 – an unmanned, 35-ft. craft in development – during a demonstration on the Atchafalaya River next to its HQ. The company partnered with the University of Louisiana at Lafayette (ULL) more than a year ago to produce technology for a vessel that can navigate without a pilot aboard. Swiftships and ULL are designing a boat that uses Global Positioning System/sensory data, and has the potential to support naval, enforcement and zone-protection operations, mainly on inland waters. AN-2 Based on Earlier
