By Louise Gray, Environment Correspondent Harbours around Britain are being ‘suffocated’ by algae according to the Government’s environment watchdog. The green seaweed saps oxygen from water – meaning other marine life cannot survive – and spreads, taking over hundreds of acres of mudflats and estuaries. The Environment Agency (EA) is so concerned about the problem […]
Sonar survey spies mysterious, 1.4-kilometer-tall feature in the depths off California By Sid PerkinsAn oceanographic survey has discovered a 1,400-meter-tall plume rising from the seafloor off the coast of California. Water samples taken at the site, about 32 kilometers northwest of Cape Mendocino, indicate that the feature isn’t mineral-rich water spewing from a hydrothermal vent, […]
By Tom Arup, Environment Correspondent THE Environment Minister, Peter Garrett, has warned that money to save endangered wildlife is limited and some species may have to be abandoned when funding decisions are made. In one of the strongest speeches of his ministerial career he told an international conference of ecologists in Brisbane that the Government […]
By ANNA M. TINSLEY As the hot days in Texas get even hotter, it may just be too much for some birds and fish. From the American goldfinch to the gray snapper, some species have been moving north for years, searching for cooler ground. And their quest may someday lead them to migrate out of […]
Features formed by melting permafrost provide clues to a changing Arctic landscape and climate By Lisa Jarvis There is a profound quietude north of Alaska’s Brooks Range, the string of mountains separating the boreal forest from the Arctic tundra. Traveling along the Dalton Highway, the one road to the Arctic Ocean, one sees little visible […]
By Mead Gruver, Associated Press Writer Cheyenne, Wyo. » Glaciers on the iconic Teton Range are shrinking, researchers say, joining a growing list of glaciers in North America and beyond that are losing their surface area and potentially reducing the water supply for nearby regions. Two of the Tetons’ biggest glaciers have lost more than […]
(University of Virginia) Massive burning of forests for agriculture thousands of years ago may have increased atmospheric carbon dioxide enough to alter global climate and usher in a warming trend that continues today, according to a new study that appears online Aug. 17 in the journal Quaternary Science Reviews. Researchers at the University of Virginia […]
The planet’s ocean surface temperature was the warmest on record for July, breaking the previous high mark established in 1998 according to an analysis by NOAA’s National Climatic Data Center in Asheville, N.C. The combined average global land and ocean surface temperature for July 2009 ranked fifth-warmest since world-wide records began in 1880. The combined […]
The warming of an Arctic current over the last 30 years has triggered the release of methane, a potent greenhouse gas, from methane hydrate stored in the sediment beneath the seabed. Scientists at the National Oceanography Centre Southampton working in collaboration with researchers from the University of Birmingham, Royal Holloway London and IFM-Geomar in Germany […]
The same things that make Alaska’s marine waters among the most productive in the world may also make them the most vulnerable to ocean acidification. According to new findings by a University of Alaska Fairbanks scientist, Alaska’s oceans are becoming increasingly acidic, which could damage Alaska’s king crab and salmon fisheries. This spring, chemical oceanographer […]
