Ocean islands fuel productivity and carbon sequestration through natural iron fertilization
An experiment to study the effects of naturally deposited iron in the Southern Ocean has supplied a key piece of the puzzle surrounding iron's role in locking atmospheric carbon dioxide in the ocean. The international research team led by Raymond Pollard of the National Oceanography Center, Southampton, and including Matthew Charette, a marine chemist at the Woods Hole Oceanographic Institution, found natural iron fertilization enhanced the export of carbon to the deep ocean.

Some of Earth's climate troubles should face burial at sea, scientists say
Making bales with 30 percent of global crop residues -- the stalks and such left after harvesting -- and then sinking the bales into the deep ocean could reduce the build up of global carbon dioxide in the atmosphere by up to 15 percent a year, according to just published calculations. It's a process that can be accomplished with existing technology and it can be done year after year, says a University of Washington researcher.

Polarstern expedition 'LOHAFEX' can be conducted
The Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association can conduct the ongoing Polarstern expedition "LOHAFEX." Independent scientific and legal reviews sought by the Federal Ministry of Research and the Federal Ministry for the Environment concluded that the iron fertilization experiment LOHAFEX is neither against environmental standards nor the international law in force. There are thus no ecological and legal reasons to further suspend the iron fertilization experiment LOHAFEX.

Dramatic expansion of dead zones in the oceans
Unchecked global warming would leave ocean dwellers gasping for breath. Dead zones are low-oxygen areas in the ocean where higher life forms such as fish, crabs and clams are not able to live. A team of Danish researchers have now shown that unchecked global warming would lead to a dramatic expansion of low-oxygen areas zones in the global ocean by a factor of 10 or more. The findings are published in the scientific journal Nature Geoscience.

Physics of the Earth and Planetary Interiors
The continents as a heat blanket
Drifting of the large tectonic plates and the superimposed continents is not only powered by the heat-driven convection processes in the Earth's mantle, but rather retroacts on this internal driving processes. In doing so, the continents function as a thermal blanket, which leads to an accumulation of heat underneath, and which in turn can cause the break-up of the super-continents.

Data from NYHOPS assists rescue efforts in Flight 1549 emergency
With its unique location along the western bank of the Hudson River, Stevens Institute of Technology provided a dramatic front row venue for the emergency landing and successful rescue of US Airways Flight 1549. While emergency workers and ferryboat operators worked quickly to pluck the 150 passengers from the water's surface, Dr. Alan Blumberg, director of the Center for Maritime Systems at Stevens, was monitoring the situation under the Hudson River.

Project MARGO: A new tool which improves the reliability of climate models
An international team of researchers, including Antoni Rosell, ICREA researcher at the Institute of Environmental Science and Technology and professor of the department of geology, Universitat Autònoma de Barcelona, have created MARGO (Multiproxy Approach for the Reconstruction of the Glacial Ocean Surface), a new quantitative tool which reconstructs the sea surface temperature during the Last Glacial Maximum. MARGO will serve to represent more exact models of the past and predict the climate's evolution in the future.

Coastal barrier island researchers learn lessons from Ike destruction
More than 20 coastal barrier island researchers came to Galveston Island in early January -- from New England, the Pacific coast and all points between where ocean meets US soil. Many had never seen the level of destruction wrought by Hurricane Ike. But now they have a goal that will involve research, management and outreach to the public in order to help the nation's barrier islands.

Climate scientist wins new $500K award
Wallace S. Broecker, a geochemist at Columbia University's Lamont-Doherty Earth Observatory, has received the newly founded Frontiers of Knowledge Award in Climate Change Research, one of the world's largest science prizes. An international jury awarded Broecker the $527,000 prize, from Spain's Banco Bilbao Vizcaya Argentaria Foundation, for sounding early alarms about climate change, and for his pioneering work on how the oceans and atmosphere interact.

Study links swings in North Atlantic oscillation variability to climate warming

Voracious sponges save reef
Tropical oceans are known as the deserts of the sea. And yet this unlikely environment is the very place where the rich and fertile coral reef grows. Dutch researcher Jasper de Goeij investigated how caves in the coral reef ensure the reef's continued existence. Although sponges in these coral caves take up a lot of dissolved organic material, they scarcely grow. However, they do discard a lot of cells that in turn provide food for the organisms on the reef.

Study: Can nature's leading indicators presage environmental disaster?
Economists use leading indicators -- the drivers of economic performance -- to take the temperature of the economy and predict the future. Now, in a new study, scientists take a page from the social science handbook and use leading indicators of the environment to presage the potential collapse of ecosystems.

Abrupt climate shifts may move faster than thought
The United States could suffer the effects of abrupt climate changes within decades -- sooner than some previously thought -- says a new government report. It contends that seas could rise rapidly if melting of polar ice continues to outrun recent projections, and that an ongoing drought in the US west could be the start of permanent drying for the region.
