Ancient coral reef tells the history of Kenya's soil erosion
04-10-2007 · EurekAlert!
Coral reefs, like tree rings, are natural archives of climate change. But oceanic corals also provide a faithful account of how people make use of land through history, says Stanford University scientist Robert B. Dunbar. In a recent study published in Geophysical Research Letters, Dunbar and his colleagues used coral samples from the Indian Ocean to create a 300-year record of soil erosion in Kenya.

Envisat captures first image of Sargassum from space
06-06-2007 · European Space Agency (ESA)
Sargassum seaweed, famous in nautical lore for entangling ships in its dense floating vegetation, has been detected from space for the first time thanks to an instrument aboard ESA's environmental satellite, Envisat. The ability to monitor Sargassum globally will allow researchers to understand better the primary productivity of the ocean and better predict climate change.

Changing ocean conditions led to decline in Alaska's sea lion population
03-22-2007 · EurekAlert!
Studies by a team of scientists at the North Pacific Universities Marine Mammal Research Consortium revealed that a sudden ocean climate change 30 years ago may be a leading factor in the decline of Alaska’s endangered western stock of Steller sea lions.

Corals and climate change
08-22-2007 · EurekAlert!
A modest new lab at the Rosenstiel School is the first of its kind to tackle the global problem of climate change impacts on corals. Fully operational this month, this new lab has begun to study how corals respond to the combined stress of greenhouse warming and ocean acidification. The lab is the first to maintain corals under precisely controlled temperature and carbon dioxide conditions while exposing them to natural light conditions.

Ocean’s ‘Twilight Zone’ Plays Important Role in Climate Change
04-26-2007 · Woods Hole Oceanographic Institution (WHOI)
A major study has shed new light on the dim layer of the ocean called the “twilight zone”—where mysterious processes affect the ocean's ability to absorb and store carbon dioxide accumulating in our atmosphere.

Research finds evidence tropical cyclones have climate-control role
05-31-2007 · EurekAlert!
Purdue University researchers have found evidence that tropical cyclones and hurricanes play an important role in the ocean circulation patterns that transport heat and maintain the climate of North America and Europe. These findings suggest that there is an additional factor to be included in climate models that may change predictions of future climate scenarios.

Antarctic icebergs -- Hotspots of ocean life
06-21-2007 · EurekAlert!
Global climate change is causing Antarctic ice shelves to shrink and split apart, yielding thousands of free-drifting icebergs in the nearby Weddell Sea. According to a new study in this week's journal Science these floating islands of ice -- some as large as a dozen miles across -- are having a major impact on the ecology of the ocean around them, serving as "hotspots" for ocean life, with thriving communities of seabirds above and a web of phytoplankton, krill and fish below.
