Has the mystery of the Antarctic ice sheet been solved?
A team of scientists from Cardiff University's School of Earth and Ocean Sciences and Amgueddfa Cymru - National Museum Wales travelled to Africa to find new evidence of climate change which helps explain some of the mystery surrounding the appearance of the Antarctic ice sheet.   view more (2008-02-28)

Voyage to Southern Ocean aims to study air-sea fluxes of greenhouse gases
Scientists will embark this week from Punta Arenas, Chile, on the tip of South America, to spend 42 days amid the high winds and waves of the Southern Ocean. Here they hope to make groundbreaking measurements to explain how huge fluxes of climate-affecting gases move between atmosphere and sea, and... view more (2008-02-27)

2 oxygenation events in ancient oceans sparked spread of complex life
The rise of oxygen and the oxidation of deep oceans between 635 and 551 million years ago may have had an impact on the increase and spread of the earliest complex life, including animals.   view more (2008-02-26)

From delicious to death: Understanding taste
Despite the significance of taste to both human gratification and survival, a basic understanding of this primal sense is still unfolding.   view more (2008-02-26)

NASA co-sponsors ocean voyage to probe climate-relevant gases
More than 30 scientists will embark next week on a research mission to the Southern Ocean. Researchers will battle the elements to study how gases important to climate change move between the atmosphere and the ocean under high winds and seas.   view more (2008-02-22)

Into the abyss: Deep-sixing carbon
Imagine a gigantic, inflatable, sausage-like bag capable of storing 160 million tonnes of CO2 - the equivalent of 2.2 days of current global emissions.   view more (2008-02-19)

Unveiling the underwater ways of the white shark
It's hard to study a creature when you only catch fleeting glimpses of it. Up until recently, that was one of the big stumbling blocks for marine biologists and ecologists, but advances in electronic tracking technology have allowed them to peer farther across, and deeper under, the surface of the... view more (2008-02-19)

Stanford researchers say living corals thousands of years old hold clues to past climate changes
Using radiocarbon dating and samples of deep-sea corals snipped from the floor of the Pacific Ocean by a submersible, researchers from Stanford and Lawrence Livermore National Laboratory have discovered that deep-sea corals growing off Hawaii are much older than previously thought-some as old as... view more (2008-02-15)

First map of threats to marine ecosystems shows all the world's oceans are affected
As vast and far-reaching as the world's oceans are, every square kilometer is affected by human activities, according to a study in the journal Science by researchers at the University of North Carolina at Chapel Hill and others.   view more (2008-02-15)

New study shows extent of harmful human influences on global ecosystems
More than 40 percent of the world's oceans are heavily impacted by human activities, including overfishing and pollution, according to a new study that will appear in tomorrow's peer-reviewed journal Science.   view more (2008-02-15)

Scientists expand understanding of how river carbon impacts the Arctic Ocean
Arctic rivers transport huge quantities of dissolved organic carbon (DOC) to the Arctic Ocean. The prevailing paradigm regarding DOC in arctic rivers is that it is largely refractory, making it of little significance for the biogeochemistry of the Arctic Ocean.   view more (2008-02-13)

Researchers give new hybrid vehicle its first test drive in the ocean
Taking a page out of a science fiction story, researchers from the Woods Hole Oceanographic Institution (WHOI) and Webb Research Corporation (Falmouth, Mass.) have successfully flown the first environmentally powered robotic vehicle through the ocean. The new robotic "glider" harvests... view more (2008-02-11)

Don't blame the trees: Social factors, not forests, dictate disease patterns
A new study published February 6 in the open access journal PLoS Neglected Tropical Diseases suggests that socioeconomic factors best explain patterns of the infectious disease American Cutaneous Leishmaniasis (ACL) in Costa Rica.   view more (2008-02-06)

Antarctic expedition provides new insights into the role of the Southern Ocean for global climate
In the Southern Ocean, large quantities of surface-drifting plankton algae are able to significantly reduce the carbon dioxide content of the surface waters, which can affect the global carbon dioxide cycle.   view more (2008-02-06)

Tipping elements in the Earth's climate system
Anthropogenic forcing could push the Earth's climate system past critical thresholds, so that important components may "tip" into qualitatively different modes of operation.   view more (2008-02-05)

Ancient climate secrets raised from ocean depths
Scientists aboard the research vessel, Southern Surveyor, return to Hobart today with a collection of coral samples and photographs taken in the Southern Ocean at greater depths than ever before.   view more (2008-02-04)

Deep-ocean researchers target tsunami zone near Japan
Rice University Earth scientist Dale Sawyer and colleagues last month reported the discovery of a strong variation in the tectonic stresses in a region of the Pacific Ocean notorious for generating devastating earthquakes and tsunamis in southeastern Japan.   view more (2008-01-18)

Paired microbes eliminate methane using sulfur pathway
Anaerobic microbes in the Earth's oceans consume 90 percent of the methane produced by methane hydrates - methane trapped in ice - preventing large amounts of methane from reaching the atmosphere.   view more (2008-01-17)

Older Arctic sea ice replaced by young, thin ice, says CU-Boulder study
A new study by University of Colorado at Boulder researchers indicates older, multi-year sea ice in the Arctic is giving way to younger, thinner ice, making it more susceptible to record summer sea-ice lows like the one that occurred in 2007.   view more (2008-01-14)

Greenhouse ocean may downsize fish
By 2100, warmer oceans with more carbon dioxide may no longer sustain 1 of the world's most productive fisheries, says USC marine ecologist.   view more (2008-01-14)

Evidence of glaciation in 'super greenhouse' world
Large ice-sheets existed on Earth about 91 million years ago, during one of the warmest periods since life began, an international team of scientists reports this week.   view more (2008-01-11)

Carbon offset warning from international team of scientists
Leading marine scientists from across the world have issued a warning that it is too early to sell carbon offsets from ocean iron fertilisation.   view more (2008-01-11)

A warming climate can support glacial ice
New research challenges the generally accepted belief that substantial ice sheets could not have existed on Earth during past super-warm climate events.   view more (2008-01-11)

'Invisibility cloaks' could break sound barriers
Contrary to earlier predictions, Duke University engineers have found that a three-dimensional sound cloak is possible, at least in theory.   view more (2008-01-10)

Earth's Moving Crust May Occasionally Stop
The motion, formation, and recycling of Earth's crust-commonly known as plate tectonics-have long been thought to be continuous processes. But new research by geophysicists suggests that plate tectonic motions have occasionally stopped in Earth's geologic history, and may do so again. The findings... view more (2008-01-10)
