State of the steric sea level rise, 1955-2003
Based on a detailed analysis of ocean vertical temperature profiles for the 1955-2008 period, Sydney Levitus, lead author, talks about the change of global average sea level induced by the observed warming of the world ocean during the past 53 years. view more (2009-02-17)
Climate change will affect carbon sequestration in oceans, model shows
The direct injection of carbon dioxide deep into the ocean has been suggested as one method to help control rising carbon dioxide levels in the atmosphere and mitigate the effects of global warming. view more (2005-09-08)
Oceanic seesaw links Northern and Southern hemisphere during abrupt climate change
Very large and abrupt changes in temperature recorded over Greenland and across the North Atlantic during the last Ice Age were actually global in extent, according to an international team of researchers led by Cardiff University. view more (2009-02-26)
Arctic ocean history is deciphered by ocean-drilling research team
Sediment cores retrieved from the Arctic's deep-sea floor by the Integrated Ocean Drilling Program's Arctic Coring Expedition (ACEX) have provided long-absent data to scientists who report new findings in the June 21 issue of Nature. view more (2007-06-21)
New Centre For Satellite Observation Established In North Wales
North Wales is to play a major role in using information from earth-orbiting satellites to improve predictions of future environmental change. The School of Ocean Sciences at University of Wales, Bangor will be part of a national Centre of Excellence in Earth Observation which is to be established with funding of £2 million from the Natural... view more...

Role of Silica in Climate Cycles
New research from the University of East Anglia (UEA) has demonstrated that the compound silica was not solely responsible for changes in carbon dioxide levels during past Ice Ages. It is already known from scientific research that during past Ice Ages increased amounts of silica, a common component of wind-blown dust, were deposited in the ocean.... view more... (2001-06-21)
Bacteria can help predict ocean change
Every creature has its place and role in the oceans - even the smallest microbe, according to a new study that may lead to more accurate models of ocean change. view more (2006-08-15)
Salty oceans provide early warning for climate change
Monitoring the saltiness of the ocean water could provide an early indicator of climate change. Significant increases or decreases in salt in key areas could forewarn of climate change in 10 to 20 years time. view more (2007-06-11)
North Atlantic slows on the uptake of CO2
Further evidence for the decline of the oceans' historical role as an important sink for atmospheric carbon dioxide is supplied by new research by environmental scientists from the University of East Anglia. view more (2007-10-23)
Catastrophic 'lake burst' chills climate
Ocean circulation changes during the present warm interglacial were more extensive than previously thought, according to new research by the University of East Anglia (UEA) and Cardiff University. view more (2006-06-30)
International meeting on the Southern Ocean
The Role of the Southern Ocean in Global Processes: an Earth System Science Approach - 14-16 July 2003, London Over 80 experts from around the world will meet next week (14-16 July) to discuss the Southern Ocean surrounding Antarctica. It's the first attempt by scientists to take a collective approach to investigating an important marine... view more... (2003-07-10)
Why oceans behave like water in a bath
SATELLITE measurements of sea levels have uncovered a bizarre effect. The sea seems to be rising faster near the coast than in mid-ocean. Simon Holgate and Philip Woodworth of the Proudman Oceanographic Laboratory, in Bidston, UK, found this discrepancy using the Topex satellite, launched in 1992. The satellite measures sea level by bouncing... view more... (2004-04-21)
Indian eddies supply Atlantic Ocean with warm water
Water from the Indian Ocean does not reach the South Atlantic Ocean continuously, but in separate packages. These are called Agulhas eddies, after the current along the east coast of Southern Africa where they originate from. view more (2005-10-11)
First British Glacial Map to predict future climate change
An academic from the University of Sheffield has produced the first glacial map of Britain, which could allow us to better predict climate change in the future. The map is published in the latest edition of the journal Boreas. view more (2004-11-23)
Carbon sinks losing the battle with rising emissions
The stabilising influence that land and ocean carbon sinks have on rising carbon emissions is gradually weakening, say scientists attending this week's international Copenhagen Climate Change Conference. view more (2009-03-17)
Climate change signal detected in the Indian Ocean
The signature of climate change over the past 40 years has been identified in temperatures of the Indian Ocean near Australia. view more (2007-05-31)
Mixing it, Southern Ocean style
Sea water being churned in the ocean off Antarctica may be having a greater effect on global patterns of ocean movement than previously thought, according to new research reported in this week's edition of the international journal Science (9 January 2004). view more (2004-01-05)
Gas from the past gives scientists new insights into climate and the oceans
In recent years, public discussion of climate change has included concerns that increased levels of carbon dioxide will contribute to global warming, which in turn may change the circulation in the earth's oceans, with potentially disastrous consequences. view more (2008-10-06)
Marine fossils improve predictions of climate change
A study of the ancient Mediterranean Sea will help to produce more accurate predictions of climate change. A team led by Royal Holloway geologist Dr Michal Kucera will map sea-surface temperature of the Mediterranean over past millennia. The data will provide a new target to test the computer models on which our predictions of climate change are... view more... (2002-06-06)
Changing ocean conditions led to decline in Alaska's sea lion population
A new study out of Alaska points out the impacts of climate change on marine ecosystems, and the need for increased research and stronger science based management to address future concerns. view more (2007-03-23)
