Dead zone in Gulf one of largest ever http://apocadocs.com/s.pl?1280837410
Scientists say this year that the "dead zone" area that forms every summer in the Gulf of Mexico is one of the largest ever measured.
The large area of low oxygen that chokes marine life comes in addition to the massive BP oil spill....
They say the dead zone is at least 7,722 square miles (20,000 square kilometres). The largest ever measured was just over 8,000 square miles (20,700 square kilometres) in 2001.
Pollution, such as runoff from farms along the Mississippi River, cause regions of low oxygen content or hypoxia in the Gulf through the introduction of nitrogen and phosphorus into the water system.
