The Earth currently has more than 400 so-called "dead zones"--expanses of oxygen-starved ocean covering hundreds, or even thousands, of square miles that become virtually devoid of animal life during the summer; the worldwide count of dead zones is doubling every decade.
Most dead zones, such as the Gulf of Mexico's notorious dead zone, are caused by pollution that is dumped into oceans by rivers. But every summer since 2002, the Pacific Northwest's coastal waters--one of the U.S.'s most important fisheries--has been invaded by massive dead zones that are believed to be caused by an entirely different and surprising phenomena: changes in oceanic and atmospheric circulation that may, in turn, be caused by climate change.
How could climate change cause dead zones? What do dead zones look like and what are their ecological impacts? And how, on Earth, are scientists sleuthing out the causes of perplexing marine processes that cover such huge swaths of the sea? Find out in the National Science Foundation's new online, multimedia package on dead zones.
Entitled Dead Zones: Mysteries of Ocean Die-Offs Revealed, the multimedia package is posted at http://nsf.gov/news/special_reports/deadzones. It features:
- a webcast with Jack Barth, an expert on Oregon's dead zones from Oregon State University;
- a dynamic, narrated slide show;
- compelling videos;
- eye-catching photos;
- enlightening illustrations
- informative, easy-to-understand texts; and
- downloadable documents.
Dead Zones: Mysteries of Ocean Die-Offs Revealed is ideal for reporters, general readers, fishermen, water-enthusiasts, teachers, students, researchers and conservation organizations.

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2019, its budget is $8.1 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 50,000 competitive proposals for funding and makes about 12,000 new funding awards.
