Global ocean temperatures rose to the warmest on record, according to data released last week by the National Oceanic and Atmospheric Administration (NOAA). The combined average global land and ocean surface temperature for June was second-warmest since global recording-keeping began in 1880. NOAA reports that both the Northern and Southern Hemispheres experienced record sea surface […]
By Noreen Parks In addition to weakening Earth’s natural shield against excessive radiation levels, ozone depletion above Antarctica has significantly dampened the Southern Ocean’s ability to absorb atmospheric CO2 and has accelerated acidification of southern polar waters, according to new research reported online June 20 in Geophysical Research Letters (2009, DOI 10.1029/2009GL038227). Of the atmospheric […]
Jane Kay, Chronicle Environment Writer Fluctuating ocean conditions may be depleting the food supply of young sea lions that are turning up skinny and ill on California beaches, mirroring the fate of Brandt’s cormorants earlier this spring. The animal strandings are so numerous that the newly expanded Marine Mammal Center in Sausalito can’t keep up. […]
EPA finds high levels of lead at Raritan Bay sites by Aliyah Shahid/For The Star-Ledger OLD BRIDGE — Tests on mussels, clams and foraging fish near the Laurence Harbor Sea Wall in Old Bridge, have revealed high levels of lead, the Environmental Protection Agency reported today. The amount of lead found in ribbed mussels ranged […]
By Doug Fraser, dfraser@capecodonline.com WOODS HOLE — Cape Cod is one of the top areas in the world for marine mammal strandings. The animals are sometimes loaded with parasites or are sick. But, despite a long history of pollution in our coastal waters, the toll pollution takes on sea creatures has been harder to establish. […]
The ecosystem of the Cape Gannet, a protected bird species, has gone haywire. As a result of overfishing, the birds are no longer able to find enough food to rear their young. Pelicans, kelp gulls and seals are becoming increasing threats – the lack of fish means that these predators are attacking Cape Gannet chicks […]
There are now 46000 pieces of plastic per square kilometre of the world’s oceans killing a million seabirds and 100000 marine mammals each year. Worse still there seems to be nothing we can do to clean it up. So how do we turn the tide? By Richard Grant Way out in the Pacific Ocean, in […]
“Leatherback turtles are ancient creatures with a modern problem: Plastic.” A new study has looked at “necropsy reports of more than 400 leatherback” turtles and found that about 1/3 of them had plastic in their digestive system. They’re not saying it was the immediate cause of death, but as Mike James, a marine biologist […]
Mercury levels in the Pacific Ocean are rising, a new study suggests.1 The increase may mean that more methylmercury, a human neurotoxin formed when mercury is methylated by microbes, accumulates in marine fish such as tuna. The research comes as researchers and policymakers, who have tended to focus on atmospheric concentrations of the element, are […]
March 25, 2009 — Fish caught near wastewater treatment plants serving five major U.S. cities had residues of pharmaceuticals in them, including medicines used to treat high cholesterol, allergies, high blood pressure, bipolar disorder and depression, researchers reported Wednesday. Findings from this first nationwide study of human drugs in fish tissue have prompted the Environmental […]
