Sea levels rising in parts of Indian Ocean; Greenhouse gases play role, study finds

ScienceDaily (2010-07-13) -- Newly detected rising sea levels in parts of the Indian Ocean, including the coastlines of the Bay of Bengal, the Arabian Sea, Sri Lanka, Sumatra and Java, appear to be at least partly a result of human-induced increases of atmospheric greenhouse gases, according to a new study.

ScienceDaily (2010-06-28) -- Researchers say this year's Gulf of Mexico "dead zone" is expected to be larger than average, continuing a decades-long trend that threatens the health of a $659 million fishery. The 2010 forecast, released by the U.S. National Oceanic and Atmospheric Administration (NOAA), calls for a Gulf dead zone of between 6,500 and 7,800 square miles, an area roughly the size of Lake Ontario.

New research sheds light on Antarctica's melting Pine Island Glacier

http://www.sciencedaily.com/releases/2010/06/100620200810.htm

ScienceDaily (2010-06-21) -- Scientists are reporting new results from an investigation into Antarctica's potential contribution to sea level rise. Thinning ice in West Antarctica is currently contributing nearly 10 per cent of global sea level rise, and scientists have identified Pine Island Glacier as a major source.
