A drop of ocean water tells a story

Scientists are still learning what’s in a drop of ocean water, according to this week’s Nature Magazine. And the answers have implications for the whole planet, says co-author Craig Carlson, an oceanographer at the University of California, Santa Barbara. Carlson is an assistant professor in the Department of Ecology, Evolution and Marine Biology.

About ten thousand bacterioplankton of the type SAR 11 are found in every drop of seawater. And yet, as explained in the article, which

Livermore researchers determine biosphere unaffected by geoengineering schemes

Using models that simulate the interaction between global climate and land ecosystems, atmospheric scientists from the Lawrence Livermore National Laboratory have shown that compensating for the carbon dioxide “greenhouse effect” by decreasing the amount of sunlight reaching the planet (geoengineering) could create a more vigorous ecosystem while helping to curb global warming.

The study suggests that planetary-scale engineering projects to lessen the amount of solar radiation reaching the

Sea squirt DNA sheds light on vertebrate evolution

Genome of Ciona intestinalis yields new insights into the origins of complex biological systems

The streamlined genome of Ciona intestinalis, a common sea squirt closely related to vertebrates on the evolutionary tree, is providing new clues about the origins of key vertebrate systems and structures including the human hormone, nervous and immune systems.

In an article for the December 13, 2002 issue of the journal Science, an international consortium of researchers reports

Will Climate Change Temper El Niño’s Tantrums?

The broad-scale warming expected from increased greenhouse gases may actually sap the strength of a typical El Niño, according to researchers at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado. In contrast, the average El Niño during the last ice age may have packed more punch than today’s. The scientists have examined the past and future behavior of El Niño using a sophisticated computer model of global climate. They present their results this week at the annual meeting

Engineers work on their SUNTANS as they track waves and beaches

Nearly a month has passed since the wounded tanker Prestige spilled thousands of tons of heavy oil into the Atlantic and fouled dozens of Spanish beaches. But anxious residents of coastal Spain and Portugal remain on high alert – wondering where and when the noxious crude will wash ashore next.

In recent years, tanker accidents have ruined fisheries and tourist beaches from Alaska to France. But do oil spills always have to end in catastrophe? Perhaps the most vulnerable beaches and coastal

North Atlantic Oscillation part of the global picture

An especially cold winter in Europe, lots of snow in Scandinavia or lots of rain in the Mediterranean are all symptoms of what meteorologists call the North Atlantic Oscillation, but a group of Penn State researchers has gone beyond the symptoms to try to decipher the dynamics of this atmospheric pattern.

“Some scientists argue that the impact of the NAO on global climate is comparable to El Nino,” says Dr. Sukyoung Lee, associate professor of meteorology. “However, most of the scientific co
