Science Nation – Pacific Dead Zones

Science Nation – Pacific Dead Zones

Ocean “dead zones” along the Washington and Oregon coasts are threatening critical U.S. fishing areas. These oxygen-depleted regions, that loose virtually all of their marine life in the summer, are expanding, and new ones are appearing in the Pacific Ocean. Oceanographer Jack Barth of Oregon State University says these new ocean dead zones are different from most of the 400+ others known around the world. While the majority of those are caused by excess nutrients in river runoffs, his research is the first to tie these new dead zones to climate change. With support from the National Science Foundation, Bath is also using an impressive new tool, an unmanned underwater glider that provides round the clock monitoring of these zones.

Submarine research in the world’s largest underwater canyons

Submarine research in the world’s largest underwater canyons

Greenpeace is researching the world’s largest underwater canyons at the bottom of the Bering Sea using a Waitt Institute submarine. The Pribiloff and Zhemchug canyons are known as the “Grand Canyons of the Sea,” yet little is known about the diversity and distribution of life on the sea floor. Today, overfishing and destructive fishing methods like trawling are damaging these canyons and threatening the food supply for marine mammals, birds and Native communities who depend on the marine ecosystem.

Climate change leaves oceans “hot, sour and breathless”

A triple-whammy of rising temperatures, increased acid levels and lack of oxygen is destroying the world’s oceans, according to scientists at the Rio+20 Earth Summit. Experts warn that small island states are being hit especially hard, with impacts on health, food and livelihoods.
