Oceans on the precipice: scientist warns of mass extinctions and 'rise of slime' Aug 13, 2008 Human activities are cumulatively driving the health of the world's oceans down a rapid spiral, and only prompt and wholesale changes will slow or perhaps ultimately reverse the catastrophic problems they ...

Explorers find hundreds of undescribed corals, other species on familiar Australian reefs Sep 18, 2008 Hundreds of new kinds of animal species surprised international researchers systematically exploring waters off two islands on the Great Barrier Reef and a reef off northwestern Australia -- waters long familiar ...

Seabird ammonia emissions contribute to atmospheric acidity Sep 23, 2008 Ammonia emissions from seabirds have been shown to be a significant source of nitrogen in remote coastal ecosystems, contributing to nutrient enrichment (eutrophication) and acidification in ecosystems. While most ammonia ...

Climate Change Seeps into the Sea Oct 24, 2008 (PhysOrg.com) -- Good news has turned out to be bad. The ocean has helped slow global warming by absorbing much of the excess heat and heat-trapping carbon dioxide that has been going into the atmosphere since ...

Marine invasive species advance 50km per decade Nov 10, 2008 A rapid, climate change-induced northern migration of invasive marine is one of many research results announced Tues. Nov. 11 during opening day presentations at the First World Conference on Marine Biodiversity, Ciudad de ...

Report: Greenhouse gases imperil oceans' web of life Nov 10, 2008 Corals, lobsters, clams and many other ocean creatures - including some at the bottom of the food chain - may be unable to withstand the increasing acidity of the oceans brought on by growing global-warming pollution, according ...
