Food source threatened by carbon dioxide
Carbon dioxide increasing in the atmosphere may affect the microbial life in the sea, which could have an impact on a major food source, warned Dr Ian Joint at a Science Media Centre press briefing today. view more (2007-12-11)
Geophysical Research Letters European Highlights - 1 August 2001
Highlights 4. Deep water has many sources Hellmer and Beckmann ["The Southern Ocean: A Ventilation Contributor with Multiple Sources"] use a coupled ocean/ice-shelf model to determine the location and rate of Antarctic Bottom Water (AABW) formation. Their results suggest that the Atlantic and Indian-Pacific are equal contributors but produce... view more... (2001-07-16)
Global sunscreen won't save corals
Emergency plans to counteract global warming by artificially shading the Earth from incoming sunlight might lower the planet's temperature a few degrees, but such "geoengineering" solutions would do little to stop the acidification of the world oceans that threatens coral reefs and other marine life. view more (2009-06-17)
Biodiversity hotspots, centres of endemicity, and the conservation of coral reefs
Coral reefs are renowned for their spectacularly high biodiversity, yet there is widespread concern for their future in the face of threats from land-clearing, over-fishing and global warming. A new study published in Ecology Letters by Australian scientists - Terry Hughes, David Bellwood and Sean Connolly has shown that biodiversity hotspots on... view more... (2002-10-30)
Richness of Marine Life is Under Threat
Future potential for the production of new wonder drugs - including anti-cancer agents - from marine animals and plants, is under threat according to biodiversity expert Professor Carlo Heip, speaking at the European marine science and ocean technology conference EurOCEAN 2004 in Galway, today. According to Professor Heip, marine biodiversity -... view more... (2004-05-11)
ESA contributes to ocean carbon cycle research
The Earth's oceans play a vital role in the carbon cycle, making it imperative that we understand marine biological activity enough to predict how our planet will react to the extra 25 000 million tonnes of carbon dioxide humans are pumping into the atmosphere annually. view more (2008-05-06)
Antarctic ice shelf retreats happened before
The retreat of Antarctic ice shelves is not new according to research published this week (24 Feb) in the journal Geology by scientists from Universities of Durham, Edinburgh and British Antarctic Survey (BAS). view more (2005-02-23)
New Deep-Sea Coral Discovered on NOAA-Supported Mission
Scientists identified seven new species of bamboo coral discovered on a NOAA-funded mission in the deep waters of the Papahānaumokuākea Marine National Monument. view more (2009-03-06)
Expedition allows teachers to participate in polar research
What better way to engage students in science than to apply lessons learned from fieldwork? This is the philosophy of Alaska teachers participating in the Arctic Expedition for K-12 Teachers, a program organized by the International Arctic Research Center (IARC) at the University of Alaska Fairbanks and a handful of international agencies. view more (2006-09-14)
Changes in net flow of ocean heat correlate with past climate anomalies
Physicists at the University of Rochester have combed through data from satellites and ocean buoys and found evidence that in the last 50 years, the net flow of heat into and out of the oceans has changed direction three times. view more (2009-08-17)
Researchers link Ice Age climate-change records to ocean salinity
Sudden decreases in temperature over Greenland and tropical rainfall patterns during the last Ice Age have been linked for the first time to rapid changes in the salinity of the north Atlantic Ocean. view more (2006-10-05)
Robot submarine reveals secret stash of key Antarctic food source under sea ice
A robot submarine expedition under the Antarctic sea ice has discovered a major food reserve in the Southern Ocean. The findings, reported this week in SCIENCE, show a dense band of the shrimp-like krill under the ice, five times more concentrated than in open water. The importance of sea ice as a nursery for krill - key food for penguins, whales... view more... (2002-03-05)
Ocean satellite launch critical to Australian science
A new earth observing satellite being launched in California today will help guide future Australian ocean and climate science. view more (2008-06-23)
University of Miami scientist uncovers miscalculation in geological undersea record
The precise timing of the origin of life on Earth and the changes in life during the past 4.5 billion years has been a subject of great controversy for the past century. view more (2008-09-11)
The Agulhas Current, in the southern hemisphere, may influence climate in Europe
Her PhD thesis "Surface and Deep Circulation off South Africa: Agulhas Leakage Influence on the Meridional Overturning Circulation During the Last 345 kyr" presented data on a major ocean current in the southern hemisphere, the Agulhas Current, which transports warm waters from the tropical Indian Ocean to the southern tip of Africa. view more (2009-03-11)
Declining sharks
The transformation of terrestrial and coastal ecosystems by humans is well known, but only recently have the impacts of anthropogenic forces in the open ocean been recognized. In particular, intense exploitation by industrial fisheries is rapidly changing oceanic ecosystems by drastically reducing populations of many marine species. For most... view more... (2004-02-05)
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)
Rising CO2 signals wetter storms for Northern Hemisphere, says CU-Boulder study
While two new studies by researchers at the University of Colorado at Boulder's Cooperative Institute for Research in Environmental Sciences predict wetter storms for the Arctic and for the Northern Hemisphere because of global warming, whether or not this means more net precipitation depends on the latitude. view more (2007-12-12)
Surf not up for Palaeozoic creatures - new model reveals ancient sea was a giant lake
The ancient sea was more like a giant salty lake than a rolling ocean, report scientists from Imperial College London in the May edition of the Journal of the Geological Society. A new computer model that simulates how tides in North West Europe would have behaved 300 million years ago shows a sea with so little movement that it was unlike any on... view more... (2005-05-09)
Higher Water Temperatures and Reduced Ice Cover In the Arctic Ocean
Over the past six weeks, scientists aboard the research vessel "Polarstern" of the Alfred Wegener Institute for Polar and Marine Research have been investigating changes in ocean temperature and sea ice cover in the area of Fram Strait between Spitsbergen and Greenland. In this area significant exchange of water masses between the Arctic Ocean... view more... (2004-08-27)
