Oxygen depletion in the world’s oceans, primarily caused by agricultural run-off and pollution, could spark the development of far more male fish than female, thereby threatening some species with extinction, according to a study published today on the Web site of the American Chemical Society journal, Environmental Science & Technology. The study is scheduled to appear in the May 1 print issue of the journal.

Scientists from around the world joined this Greek island’s 250 residents and countless visitors Wednesday in cheering the drama of the Moon totally blocking the Sun, revealing the dancing glow of its corona.

“It was even more fabulous than we expected,” said Jay Pasachoff, professor of astronomy at Williams College (in Williamstown, Mass.) who observed his 42nd solar eclipse. “All the technical equipment worked perfectly, the corona shone brightly, and the activity aroun

Proposals by environmentalists to declare small areas of the North Sea as ’no-fishing’ zones would not save our flagging fish stocks, suggests a new report by Newcastle University for the British Government’s Department for Environment, Food and Rural Affairs. (DEFRA).

Marine protected areas (MPAs) would need to be tens of thousands of square miles in size – at least as big as the size of Wales – and would need to be established for decades to restore levels of c

Around the world, seagrass beds – shallow-water ecosystems that are important habitats, food sources, and sediment stabilizers – are in decline, says Frederick Short, research professor of natural resources and marine science at the University of New Hampshire. And as these underwater meadows disappear, so do commercially valuable shellfish and fish, waterfowl and other wildlife, water quality, and erosion prevention.

For more than a decade space-based radar instruments have been routinely observing ocean surface phenomena including wind, waves, oil slicks, even the eyes of hurricanes. Now – employing the same principle as police speed guns – satellite radar has also begun to enable direct measurements of the speed of the moving ocean surface itself.

The oceans that cover 71% of the Earth’s surface are constantly in motion. Ocean surface currents can lead to strong interaction with wind and wa
