Outpacing climate change with atmospheric research collaboration
Tiny particles in air create smog, seed clouds and control how much of the sun's heat makes it through the atmosphere, and yet are the least understood aspect of climate research. The Department of Energy's Pacific Northwest National Laboratory and the University of California, San Diego will focus on these particulates with the new Aerosol Chemistry and Climate Institute to better understand how aerosols from pollution, oceans and wildfires contribute to shifting regional weather.

Global sea-rise levels by 2100 may be lower than some predict, says CU-Boulder study
Despite projections by some scientists of global seas rising by 20 feet or more by the end of this century as a result of warming, a new University of Colorado at Boulder study concludes that global sea rise of much more than 6 feet is a near physical impossibility.

Warmer seas linked to strengthening hurricanes: FSU study fuels global warming debate
The theory that global warming may be contributing to stronger hurricanes in the Atlantic over the past 30 years is bolstered by a new study led by a Florida State University researcher. The study will be published in the Sept. 4 edition of the journal Nature.

Unexplored Arctic region to be mapped
A scientific expedition this fall will map the unexplored Arctic seafloor where the US and Canada may have sovereign rights over natural resources such as oil and gas and control over activities such as mining. Both countries will use the resulting data to establish the outer limits of the continental shelf, according to the criteria set out in the Convention on the Law of the Sea.

Complex ocean behavior studied with 'artificial upwelling'
A team of scientists is studying the complex ocean upwelling process by mimicking nature -- pumping cold, nutrient-rich water from deep within the Pacific Ocean and releasing it into surface waters near Hawaii that lack the nitrogen and phosphorous necessary to support high biological production.

Ice Age lesson predicts a faster rise in sea level
If the lessons being learned by scientists about the demise of the last great North American ice sheet are correct, estimates of global sea level rise from a melting Greenland ice sheet may be seriously underestimated. Writing this week (Aug. 31) in the journal Nature Geoscience, a team of researchers led by University of Wisconsin-Madison geologist Anders Carlson reports that sea level rise from greenhouse-induced warming of the Greenland ice sheet could be double or triple current estimates over the next century.

Third International Biologging Science Symposium
Third International Biologging Science Symposium Sept. 1-5 in Pacific Grove, Calif.
"Biologging" is the use of electronic sensors, implanted or attached to animals, to track and record their movements, behaviors, physical setting and physiological state in the wild. This research, made possible through development of compact and lightweight microprocessors, is providing scientists with unprecedented views into the lives and activities of highly migratory species on land, in the sea and in the air.

Arctic ice on the verge of another all-time low
Following last summer's record minimum ice cover in the Arctic, current observations from ESA's Envisat satellite suggest that the extent of polar sea-ice may again shrink to a level very close to that of last year.

Unique study shows oil, gas seismic work not affecting Gulf sperm whales
In recent years, there has been concern that man-made noise may be a cause of stress for dolphins, whales and other marine mammals, but the results of a five-year study show that noise pollution seems to have minimal effect on endangered sperm whales in the Gulf of Mexico, say researchers from Texas A&M University who led the project and released their 323-page report today at the Houston Museum of Natural Science.

RV Polarstern on its way to East Siberian Sea
German research vessel Polarstern, operated by the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association, transits the Northwest Passage for the first time. Polarstern left the port of Reykjavik on Aug. 12, is now located in the Northwest Passage. Its destination is the East Siberian Sea where geoscientific measurements at the junction between the Mendeleev Ridge and the East Siberian Shelf are the subject.

Dartmouth workshop sets research agenda for environmental mercury
Embracing the belief that an interdisciplinary and coordinated research agenda can have a profound impact on advancing science and influencing policy, a group of experts has developed a roadmap for improving our understanding of how mercury moves through the marine ecosystem and into the fish we eat.

Signals from the Atlantic salmon highway
For years scientists have struggled to understand the decline and slow recovery of Atlantic salmon, a once abundant and highly prized game and food fish native to New England rivers. Biologists agree that poor marine survival is affecting salmon in the US and Canada, but specific causes are difficult to determine in the ocean. Small acoustic tags and associated technology may provide some answers.

Study shows continued spread of 'dead zones'
A new study shows that the number of "dead zones" -- areas of seafloor with too little oxygen for most marine life -- has increased by a third between 1995 and 2007. Dead zones are now "the key stressor on marine ecosystems" and "rank with over-fishing, habitat loss, and harmful algal blooms as global environmental problems."

Oceans on the precipice: Scripps scientist warns of mass extinctions and 'rise of slime'
Human activities are cumulatively driving the health of the world's oceans down a rapid spiral, and only prompt and wholesale changes will slow or perhaps ultimately reverse the catastrophic problems they are facing.

New robot scouts best locations for components of undersea lab
Like a deep-sea bloodhound, Sentry -- the newest in an elite group of unmanned submersibles able to operate on their own in demanding and rugged environments -- has helped scientists pinpoint locations for two observation sites of a pioneering seafloor laboratory being planned off Washington and Oregon. Successful selection of the two sites is a crucial step in developing an extensive sensor network above and below the seafloor on the Juan de Fuca Plate.

Antarctic climate: Short-term spikes, long-term warming linked to tropical Pacific
Dramatic year-to-year temperature swings and a century-long warming trend across West Antarctica are linked to conditions in the tropical Pacific, according to an analysis of ice cores. The findings show the connection of the world's coldest continent to global warming, as well as to events such as El Niño.

Successful series of measurements in Arctic sea ice
After working in regions up to 82° N, RV Polarstern of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association enters port in Reykjavik on August 10. "We had to cope with heavy ice coverage," says chief scientist Gerhard Kattner. The sea ice covered the Arctic almost down to latitude 72°. Perpetual winds from the northwest have moved the ice into the Fram Strait since the beginning of summer.
