Reviving 100-year-old resting spores of diatoms
Diatoms account for a large proportion of the phytoplankton found in the water, and live both in the open sea and in freshwater lakes. By reviving 100-year-old spores that had laid buried and inactive in bottom ...
Ancient catastrophic drought leads to question: How severe can climate change become?
How severe can climate change become in a warming world? Worse than anything we've seen in written history, according to results of a study appearing this week in the journal Science.
Antarctic sea temperatures cooled in Holocene but now rising: study
Dramatic ocean circulation changes revealed
The unusually cold weather this winter has been caused by a change in the winds. Instead of the typical westerly winds warmed by Atlantic surface ocean currents, cold northerly Arctic winds are influencing ...
Early settlers rapidly transformed New Zealand forests with fire
New research indicates that the speed of early forest clearance following human colonisation of the South Island of New Zealand was much faster and more intense than previously thought.
Bering Sea was ice-free and full of life during last warm period, study finds
Deep sediment cores retrieved from the Bering Sea floor indicate that the region was ice-free all year and biological productivity was high during the last major warm period in Earth's climate history.
As Arctic temperatures rise, tundra fires increase, researchers find
In September, 2007, the Anaktuvuk River Fire burned more than 1,000 square kilometers of tundra on Alaska's North Slope, doubling the area burned in that region since record keeping began in 1950. A new analysis ...
URI oceanographer to lead return visit to least inhabited place on Earth
(PhysOrg.com) -- Four University of Rhode Island oceanographers depart next week for an international research expedition to the middle of the South Pacific Gyre - an area that is as far from any continent as is possible ...
Large CO2 release speeds up ice age melting
Radiocarbon dating is used to determine the age of everything from ancient artifacts to prehistoric corals on the ocean bottom.
How fast can microbes break down oil washed onto Gulf beaches?
A new Florida State University study is investigating how quickly the Deepwater Horizon oil carried into Gulf of Mexico beach sands is being degraded by the sands' natural microbial communities, and whether ...
Arctic ice at low point compared to recent geologic history
Less ice covers the Arctic today than at any time in recent geologic history. That's the conclusion of an international group of researchers, who have compiled the first comprehensive history of Arctic ice.
Scientists detect huge carbon 'burp' that helped end last ice age
(PhysOrg.com) -- Scientists have found the possible source of a huge carbon dioxide 'burp' that happened some 18,000 years ago and which helped to end the last ice age.
Coastal birds carry toxic ocean metals inland
A collaborative research team led by Queen's University biologists has found that potent metals like mercury and lead, ingested by Arctic seabirds feeding in the ocean, end up in the sediment of polar ponds.
Study finds rising levels of dioxins from common soap ingredient in Mississippi River
Specific dioxins derived from the antibacterial agent triclosan, used in many hand soaps, deodorants, dishwashing liquids and other consumer products, account for an increasing proportion of total dioxins ...
