Researchers have uncovered a strikingly pattern for ancient mass extinctions: extinctions rates during mass extinctions were significantly higher in open-ocean-facing settings than in epicontinental seas, indicating that open-ocean settings were more susceptible to the mass-extinction-causing agents.
A species of common skate is to become the first marine fish species to be driven to extinction by commercial fishing, due to an error of species classification 80 years ago.
With thousands of stinging cells that can emit deadly venom from tentacles that can reach ten feet in length, the 50 or so species of box jellyfish have long been of interest to scientists and to the public. Yet little has been known about the evolution of this early branch in the animal tree of life. Researchers have now unraveled the evolutionary relationships among the various species of box jellyfish, thereby providing insight into the evolution of their toxicity.
A new study finds that a species of sea star stays cool using a strategy never before seen in the animal kingdom. The sea stars soak up cold sea water into their bodies during high tide as buffer against potentially damaging temperatures brought about by direct sunlight at low tide.
Recording hundreds of thousands of individual uplinks from satellite transmitters fitted on penguins, albatrosses, sea lions, and other marine animals, the Wildlife Conservation Society and BirdLife International have released the first-ever atlas of the Patagonian Sea -- a globally important but poorly understood South American marine ecosystem.

The oceans play a key role in regulating climate, absorbing more than a quarter of the carbon dioxide that humans put into the air. Now, the first year-by-year accounting of this mechanism during the industrial era suggests the oceans are struggling to keep up with rising emissions -- a finding with potentially wide implications for future climate.
A new study of Antarctica's past climate reveals that temperatures during the warm periods between ice ages (interglacials) may have been higher than previously thought. The latest analysis of ice core records suggests that Antarctic temperatures may have been up to 6°C warmer than the present day.
Nine research challenges and four research initiatives that are poised to advance the study of how Earth's landscapes change were unveiled by the National Research Council.
The calculation of variations in the sea level is relatively simple. It is by far more complicated to then determine the change in the water mass. A team of geodesists and oceanographers have now, for the first time succeeded in doing this. The researchers were able to observe short-term fluctuations in the spatial distribution of the ocean water masses. Their results are, amongst others, important for improved climate models.

New York Times: The Earth's oceans, which have absorbed carbon dioxide from fuel emissions since the dawn of the industrial era, have recently grown less efficient at sopping it up, new research suggests. Emissions from the burning of fossil fuels began soaring in the 1950s, and oceans largely kept up, scientists say. But the growth in the intake rate has slowed since the 1980s, and markedly so since 2000, the authors of a study write in a report in Thursday's issue of Nature. The research ...
Agence France-Presse: Japanese whaling ships left port Thursday for Antarctic waters for the annual hunt of the ocean giants, Greenpeace said, setting the stage for high-seas confrontations with anti-whaling activists. The factory ship Nisshin Maru and the smaller Yushin Maru 2 and 3 left the western port of Innoshima shortly after 10am (0100 GMT) for what is usually a five-month voyage, said the environmental activist group. Japan kills hundreds of whales a year in Antarctic waters by using a ...
GMA: Effects of climate change have driven women in communities in coastal areas in poor countries like the Philippines to risk dangerous jobs, and sometimes even into the flesh trade. Suneeta Mukherjee, country representative of the United Nations Food Population Fund (UNFPA), said women in the Philippines are the most vulnerable to the effects of climate change in the country. "Climate change could reduce income from farming and fishing possibly driving some women into sex work ...

Now, the first year-by-year accounting of this mechanism during the industrial era suggests the oceans are struggling to keep up with rising emissions -- a finding with potentially wide implications for future climate. The study appears in the November 19 issue of the journal Nature. The researchers estimate that the oceans last year took up a record 2.3 ...
Inter Press Service: The idea of wilderness is "an interesting concept; it is a Western concept. Our people have always lived and interacted in the environment," said Illion Merculieff, an environmental activist from the Aleut community in the north-western U.S. state of Alaska. The Aleuts have inhabited the islands and coastal areas of the Bering Sea, in the northern Pacific, for more than 10,000 years, having adapted to the extreme climate. "Adaptation is absolutely essential," according to ...

Ship captains and pleasure boaters can now get free real-time information on water and weather conditions for Cherry Point, Wash., from a newly installed NOAA ocean observing system that makes piloting a ship safer and more efficient.
The combined global land and ocean surface temperature was the sixth warmest October on record, according to NOAA’s National Climatic Data Center in Asheville, N.C. Based on records going back to 1880, the monthly National Climatic Data Center analysis is part of the suite of climate services NOAA provides.
The ocean and the land are natural sponges, or sinks, that absorb carbon dioxide, or CO2, from the atmosphere. But a group of international scientists, including two from NOAA, have found that the emissions are outpacing the ability of the sinks to soak up the excess CO2.
The Antarctic ozone hole, which fluctuates throughout the late winter and spring in the southern hemisphere, reached its 2009 peak circumference in late September, according to measurements by NOAA researchers. Slightly smaller than the North American continent, the ozone hole covered 9.2 million square miles, according to NOAA satellite observations. This ranks as the 10th largest since satellite measurements began in 1979.
NOAA today released the World Ocean Database 2009, the largest, most comprehensive collection of scientific information about the oceans with records dating as far back as 1800. This product is part of the climate services provided by NOAA.
