NOAA scientist Sue Moore reported at the 2010 Alaska Marine Science Symposium on a study that related the changes in Arctic sea ice extent with the movements and habitats of polar bears, walruses, and gray whales in the Pacific side of the Arctic region. MORE >>

A new study has yielded surprising findings about how the shells of marine organisms might stand up to an increasingly acidic ocean in the future. Under very high experimental CO2 conditions, the shells of clams, oysters, and some snails and urchins partially dissolved. But other species seemed as if they would not be harmed, and crustaceans, such as lobsters, crabs, and prawns, appeared to increase their shell-building. MORE >>

A species of sea star (the ochre star, Pisaster ochraceus) has figured out a novel way of keeping cool on rocky shorelines. The animal literally soaks up chilly water during high tides to protect itself from the blazing temperatures that persist when the tide goes out. MORE >>

The World Ocean Database 2009 is the largest, most comprehensive collection of scientific information about the oceans with records dating as far back as 1800. The 2009 database, updated from the 2005 edition, is significantly larger providing approximately 9.1 million temperature profiles and 3.5 million salinity reports. The 2009 database also captures 29 categories of scientific information from the oceans, including oxygen levels and chemical tracers, plus information on gases and isotopes that can be used to trace the movement of ocean currents.
