Lohafex provides new insights on plankton ecology
The Indo-German team of scientists from the National Institute of Oceanography and the Alfred Wegener Institute has returned from its expedition on research vessel Polarstern. The cooperative project Lohafex has yielded new insights on how ocean ecosystems function. But it has dampened hopes on the potential of the Southern Ocean to sequester significant amounts of carbon dioxide and thus mitigate global warming.

Proceedings of the National Academy of Sciences
Deep-sea corals may be oldest living marine organism
Deep-sea corals from about 400 meters off the coast of the Hawaiian Islands are much older than once believed and some may be the oldest living marine organisms known to man. Researchers from Lawrence Livermore, Stanford University and the University of California at Santa Cruz have determined that two groups of Hawaiian deep-sea corals are far older than previously recorded.

Seismological Research Letters
Scientists cable seafloor seismometer into California's earthquake network
Earthquake monitoring stations are almost always on land, but what about the 70 percent of the Earth's surface under water? California's first permanent seafloor seismic station has now been linked real-time into the Northern California seismic network, allowing scientists to get a more complete picture of the state's fault system -- especially the San Andreas Fault, which runs along the coast. The seafloor seismometer, built by UC Berkeley, was placed on the ocean bottom by MBARI.

DEIMOS joins MARS and its satellite of instruments on seafloor
The planet Mars has a moon named Deimos, so it seems only appropriate that the ocean observatory MARS in Monterey Bay have its own DEIMOS. This DEIMOS, however, is an underwater acoustic package designed to monitor movements of fish and zooplankton.

UK robot sub searches for signs of melting 60 km into an Antarctic ice shelf cavity
Autosub, a robot submarine built and developed by the UK's National Oceanography Center, Southampton, has successfully completed a high-risk campaign of six missions traveling under an Antarctic glacier. Autosub has been exploring Pine Island Glacier, a floating extension of the West Antarctic ice sheet, using sonar scanners to map the seabed and the underside of the ice as it juts into the sea. Scientists hope to learn why the glacier has been thinning and accelerating.

Sea level rise due to global warming poses threat to New York City
Global warming is expected to cause the sea level along the northeastern US coast to rise almost twice as fast as global sea levels during this century, putting New York City at greater risk for damage from hurricanes and winter storm surge, according to a new study led by a Florida State University researcher.

Phytoplankton is changing along the Antarctic Peninsula
As the cold, dry climate of the western Antarctic Peninsula becomes warmer and more humid, phytoplankton -- the bottom of the Antarctic food chain -- is decreasing off the northern part the peninsula and increasing further south, Rutgers marine scientists have discovered.

1-stop-shop for seamount managers and researchers: Launch of new SeamountsOnline portal
A free online portal, SeamountsOnline (http://seamounts.sdsc.edu/), is providing deep-sea researchers and managers with new tools for finding and accessing information on the biological communities that live on seamounts (undersea mountains), facilitating improved management of seamount resources, and conservation of seamount habitat.

Science
Wind shifts may stir CO2 from Antarctic depths
Natural releases of carbon dioxide from the Southern Ocean due to shifting wind patterns could have amplified global warming at the end of the last ice age -- and could be repeated as man-made warming proceeds, a new paper in the journal Science suggests.

Oxford's Dr. Rosalind Rickaby receives 2009 Rosenstiel Award
The University of Miami's Rosenstiel School of Marine and Atmospheric Science announced today that it has selected Rosalind E.M. Rickaby, Ph.D., as recipient of the 2009 Rosenstiel Award. A university lecturer in Biogeochemistry and a Tutorial Fellow of Wolfson College, Rickaby works in the Department of Earth Sciences at the University of Oxford. The Rosenstiel Award honors scientists who are already making outstanding scientific contributions in their early to mid-career stages.

Climate change reduces nutritional value of algae
Micro-algae are growing faster under the influence of climate change. However, the composition of the algae is changing, as a result of which their nutritional value for other aquatic life is decreasing. And because algae are at the bottom of the food chain, climate change is exerting an effect on underwater life. This is the conclusion of researchers from the Netherlands Institute for Ecology and the Universiteit van Amsterdam.

The Agulhas Current, in the southern hemisphere, may influence climate in Europe
The Ph.D. project presented by Gema Martínez-Méndez from the Institute of Environmental Science and Technology at the Universitat Autonoma de Barcelona focuses on the Agulhas Current and the ensuing warm water transports from the tropical Indian Ocean to the southern tip of Africa. The data generated provide for the first time evidence in support of the hypothesis that the Agulhas water "leakage" into the Atlantic can affect the climate in Europe.

Coral reefs may start dissolving when atmospheric CO2 doubles
Rising carbon dioxide in the atmosphere and the resulting effects on ocean water are making it increasingly difficult for coral reefs to grow, say scientists. A study to be published in Geophysical Research Letters by researchers at the Carnegie Institution and the Hebrew University of Jerusalem warns that if carbon dioxide reaches double pre-industrial levels, coral reefs can be expected to not just stop growing, but also to begin dissolving all over the world.

New deep-sea coral discovered on NOAA-supported mission
Scientists identified seven new species of bamboo coral discovered on a NOAA-funded mission in the deep waters of the Papahanaumokuakea Marine National Monument. Six of these species may represent entirely new genera, a remarkable feat given the broad classification a genus represents. Scientists expect to identify more new species as analysis of samples continues.
