Erosion rates double along portion of Alaska's coast
Skyrocketing coastal erosion occurred in Alaska between 2002 and 2007 along a 64 kilometer (40 mile) stretch of the Beaufort Sea, a new study finds. The surge of erosion in recent years, averaging more than double historical rates, is threatening coastal towns and destroying Alaskan cultural relics. view more (2009-02-19)
Sprats With Polonium
There are many radioactive elements in the world. For example, natural element polonium has 33 radioactive isotopes. Fortunately, only one isotope, 210Po, has a relatively long (138.4 days) half-life period. This isotope appears in the atmosphere as a result of radon decay, sinks to oceans and seas, and accumulates in organs of some animals, in... view more... (2002-07-19)
Stanford researchers say living corals thousands of years old hold clues to past climate changes
Using radiocarbon dating and samples of deep-sea corals snipped from the floor of the Pacific Ocean by a submersible, researchers from Stanford and Lawrence Livermore National Laboratory have discovered that deep-sea corals growing off Hawaii are much older than previously thought-some as old as 4,000 years. view more (2008-02-15)
Virus decimates algal blooms
As soon as the pest algae run out of nutrients, viruses attack and abruptly end the algal bloom. This is revealed in a three-year international study under the leadership of the Netherlands Institute for Sea Research. This knowledge opens up opportunities for using natural enemies to remove algal blooms in isolated areas. The pest alga species... view more... (2002-11-15)

Scientist issues warning over UK's coastal development
A scientist at Royal Holloway, University of London has condemned some of the recent developments on the coastline of south-east England as inappropriate in terms of medium and long term coastal management, largely due to their location on a examples of unstable coastline. Dr Peter French, an expert on coastal erosion in the Department of... view more... (2002-05-14)
Melting threat from West Antarctic Ice Sheet may be less than expected, could hit US hardest
While a total or partial collapse of the West Antarctic Ice Sheet as a result of warming would not raise global sea levels as high as some predict, levels on the U.S. seaboards would rise 25 percent more than the global average and threaten cities like New York, Washington, D.C., and San Francisco, according to a new study. view more (2009-05-15)
Coral reef decline-not just overfishing
Coral reefs, the rainforests of the sea, feed a large portion of the world's population, protect tropical shorelines from erosion, and harbor animals and plants with great potential to provide new therapeutic drugs. view more (2005-08-24)

Richness of Marine Life is Under Threat
Future potential for the production of new wonder drugs - including anti-cancer agents - from marine animals and plants, is under threat according to biodiversity expert Professor Carlo Heip, speaking at the European marine science and ocean technology conference EurOCEAN 2004 in Galway, today. According to Professor Heip, marine biodiversity -... view more... (2004-05-11)
New study shows extent of harmful human influences on global ecosystems

Arctic sea ice recovers slightly in 2009, remains on downward trend, says U. of Colorado report
Despite a slight recovery in summer Arctic sea ice in 2009 from record-setting low years in 2007 and 2008, the sea ice extent remains significantly below previous years and remains on a trend leading toward ice-free Arctic summers, according to the University of Colorado at Boulder's National Snow and Ice Data Center. view more (2009-10-07)
390-million-year-old scorpion fossil -- biggest bug known
The gigantic fossil claw of an 390 million-year-old sea scorpion, recently found in Germany, shows that ancient arthropods - spiders, insects, crabs and the like - were surprisingly larger than their modern-day counterparts. view more (2007-11-26)
Research shows loggerhead sea turtles threatened by small-scale fishing operations
Washington, DC. Ocean Conservancy Scientist, Wallace J. Nichols and University of California-Santa Cruz researcher Hoyt Peckham found surprising results in a recent peer-reviewed loggerhead sea turtle study that Nichols and Peckham conducted over the course of 10 years. The full study will be published on October 17 in the online, open-access... view more... (2007-10-17)
Europeans took the long way round - new support for southern exit out of Africa
All non-Africans descend from a group of humans that left Africa by a coastal route across the mouth of the Red Sea to South Asia - rather than by a direct route to Europe - less than 80,000 years ago. view more (2005-05-12)
British oceanographers find 'smoking' submarine volcano in the Indian Ocean
At over three thousand metres down in the north-west Indian Ocean, the Carlsberg Ridge is "probably the best ridge in the world". So say excited scientists from Southampton Oceanography Centre who have just found the first evidence of hydrothermal activity in this previously unexplored area of a volcanic mid-ocean ridge. The team aboard... view more... (2003-07-29)
32-mile cable installed for first deep-sea observatory
Oceanographers have completed an important step in constructing the first deep-sea observatory off the continental United States. Workers in the multi-institution effort laid 32 miles (52 kilometers) of cable along the Monterey Bay sea floor that will provide electrical power to scientific instruments, video cameras, and robots 3,000 feet (900... view more...
