Researchers have drawn together 200 years' worth of oceanographic knowledge to investigate the distribution of a notorious deep-sea giant - the king crab. The results reveal temperature as a driving force behind the divergence of a major seafloor predator; globally, and over tens of millions of years of Earth's history.
Scientists will sequence the genomes of four species of labyrinthulomycetes. These little-known marine species were selected for sequencing as the result of a proposal submitted to the competitive JGI Community Sequencing Program by a team of microbiologists.
Changes in ocean chemistry -- a consequence of increased carbon dioxide emissions from human industrial activity -- could cause US shellfish revenues to drop significantly in the next 50 years, according to a new study.
The blooming of toxic algae that occurs during the summer conceal a fight for life and death. Scientists now propose that algal blooms are created when aggressive algae kill and injure their competitors in order to absorb the nutrients they contain.
When the ancestors of present marine mammals returned to the oceans, their physiology had to adapt radically. Scientists have been studying how myoglobin, the molecule responsible for delivering oxygen to the muscles during locomotion, has been modified in seals and whales to help them cope with the needs of a life at sea.

New research, which reconstructs the extent of ice in the sea between Greenland and Svalbard from the 13th century to the present indicates that there has never been so little sea ice as there is now.
Two Australian researchers have defined a newly recognized kind of explosive eruption, termed "neptunian," that is restricted to seafloor volcanoes.
The late Pliocene onset of major Northern Hemisphere glaciation is one of the most important steps in the Cenozoic global cooling. Although most attempts have been focused on high-latitude climate feedbacks, no consensus has been reached in explaining the forcing mechanism of this dramatic climate change.

Oceanographers have found so few organisms beneath the seafloor that it may be the least inhabited sediment ever explored for evidence of life.

ScienceDaily: El Niño years typically result in fewer hurricanes forming in the Atlantic Ocean. But a new study suggests that the form of El Niño may be changing potentially causing not only a greater number of hurricanes than in average years, but also a greater chance of hurricanes making landfall, according to climatologists at the Georgia Institute of Technology. The study appears in the July 3, 2009, edition of the journal Science. "Normally, El Niño results in diminished hurricanes in the ...
Xinhua: A New Zealand scientist warned on Thursday of rising sea levels due to Antarctic ice melt. A New Zealand scientist warned on Thursday of rising sea levels due to Antarctic ice melt.?(File photo) Tim Naish said new evidence showed that changes to Antarctica's most vulnerable element, the West Antarctic ice sheet, could raise global sea levels by up to 5 metres. The Director of Victoria University's Antarctic Research Centre will present this new evidence at his ...
Greenpeace: After a week of discussions on the huge problems facing the tuna industry, countries attending the second joint meeting of tuna Regional Fisheries Management Organisations (RFMOs) in Spain have failed once again to take any action to solve the threats facing the world's favourite fish. Greenpeace was disappointed to see that the only real outcome of the meeting was an agreement that the RFMOs convene four workshops in one year's time. "It's been yet another week of inaction," ...
National Public Radio: Reporting in Nature Geoscience, two coastal scientists write that rising sea levels, combined with slow Mississippi Delta growth, could drown the Louisiana coast by 2100. Delta expert Ivor van Heerden, who is not involved with the research, discusses the findings
Mongabay: Nearly 17,000 plant and animal species are known to be threatened with extinction, while more than 800 have disappeared over the past 500 years, reports the International Union for Conservation of Nature (IUCN). The group warns that governments will miss their 2010 target for reducing biodiversity loss. "When governments take action to reduce biodiversity loss there are some conservation successes, but we are still a long way from reversing the trend," says Jean-Christophe Vié, Deputy ...

A hired master, vessel owners and permit holders of the Alaskan fishing vessel Trident have agreed to pay more than $18,000 in penalties and $241,000 worth of sanctions for falsely reporting areas fished by the vessel on five trips during 2006 and 2007.
NOAA and NASA officials announced a new Geostationary Operational Environmental Satellite (GOES), launched tonight, successfully reached orbit, joining three other GOES spacecraft that help NOAA forecasters track life-threatening weather and solar storms.
The Commerce Department today announced the appointment of 30 new and returning members to the eight regional fishery management councils – important partners with NOAA’s Fisheries Service in determining how ocean fisheries are managed.
The 2009 Volvo Environmental Prize Foundation has named NOAA Senior Scientist Susan Solomon as the recipient of its 2009 environmental prize.
Some of the substances that are helping to avert the destruction of the ozone layer could increasingly contribute to climate warming, according to scientists from NOAA’s Earth System Research Laboratory and their colleagues in a new study published today in the journal Proceedings of the National Academy of Sciences.
