Key findings published in Nature

A group of ocean-drilling research scientists that explored the Arctic Ocean subseafloor in Fall 2004 have released new findings in a report to be published in Nature on June 1. The report, supported by Integrated Ocean Drilling Program (IODP) research operations, contains analyses of subseafloor sediment samples gathered from 430 meters beneath the Arctic Ocean, near the North Pole. To recover the sediments that yielded the prehistoric climate reco

Arctic ice formed about 45 million years ago – roughly 14 million years ahead of previous predictions – according to new research published in Nature. An international team of scientists, including Brown geologist Steven Clemens, says this startling evidence shows that glaciers formed in tandem at Earth’s poles, providing important insights into global climate change.

For the first time, scientists have pulled up prehistoric geologic records from the frigid vault of the Arct

Comfortable living is not why so many different life forms seem to converge at the warmer areas of the planet.

Writing this week in the Proceedings of the National Academy of Sciences, scientists say higher temperatures near the equator speed up the metabolisms of the inhabitants, fueling genetic changes that actually lead to the creation of new species.

Human induced climate change, rather than naturally occurring ocean cycles, may be responsible for the recent increases in frequency and strength of North Atlantic hurricanes, according to Penn State and Massachusetts Institute of Technology researchers.

“Anthropogenic factors are likely responsible for long-term trends in tropical Atlantic warmth and tropical cyclone activity,” the researchers report in an upcoming issue of the American Geophysical Society’s EOS.

An international team of scientists has presented its findings from the first observations of the eruption of a submarine volcano that in 2004 and 2005 spewed out plumes of sulfur-rich fluid and pulses of volcanic ash 550 meters below the ocean’s surface near the Mariana Islands northwest of Guam.

Those findings will be published Thursday in Nature – just after many of those same scientists returned from another expedition to the site, where they observed new bursts of erupting

Kelp forest ecosystems that span the West Coast –– from Alaska to Mexico’s Baja Peninsula –– are at greater risk from overfishing than from the effects of run-off from fertilizers or sewage on the shore, say scientists at the University of California, Santa Barbara. The findings have important implications for the design of California’s Marine Protected Areas.

In an article published in the May 26 issue of Science, scientists describe the first study to compare the top-down ver
