Cranking up the volume-- Sounds travel farther underwater as world's oceans become more acidic
It is common knowledge that the world's oceans and atmosphere are warming as humans release more and more carbon dioxide into the Earth's atmosphere. However, fewer people realize that the chemistry of the oceans is also changing--seawater is becoming more acidic as carbon dioxide from the atmosphere dissolves in the oceans. view more (2008-09-30)
NASA research reveals climate warming reduces ocean food supply
In a NASA study, scientists have concluded that when Earth's climate warms, there is a reduction in the ocean's primary food supply. This poses a potential threat to fisheries and ecosystems. view more (2006-12-07)
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)
Modest CO2 cutbacks may be too little, too late for coral reefs
How much carbon dioxide is too much? According to United Nations Framework Convention on Climate Change (UNFCCC) greenhouse gases in the atmosphere need to be stabilized at levels low enough to "prevent dangerous anthropogenic interference with the climate system." But scientists have come to realize that an even more acute danger than... view more... (2008-09-23)
Ocean warming on the rise
Increased scientific confidence that ocean observations are accurately reflecting rising global temperatures is central to new Australian research published today in the journal, Nature. view more (2008-06-19)
Big and small dents
The Earth explorer satellite GOCE (Gravity Field and Steady-State Ocean Circulation Explorer), built by the European Space Agency ESA, was successfully launched today at 15:21 GMT from the Russian Cosmodrome Plesetsk. GOCE is the first satellite mission within the framework of the Living Planet Programme of ESA and will map Earth's gravity field... view more... (2009-03-18)
Phytoplankton bounce back from abrupt climate change
Marine sediment cores contain calcareous plankton - single-celled organisms with a coating or shell of calcium carbonate - as fossils. These tiny photosynthesizing plants float in the ocean and move with the currents. view more (2006-02-17)
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)
Plymouth Leads 'healthy Oceans' Research
Plymouth researchers will be presenting new research findings at an international conference they are hosting in the city next month. Professor Paul Worsfold, Co-director of Plymouth Environmental Research Centre (PERC), heads the Plymouth team working on a three-year research project which investigates the role of iron in ocean productivity and... view more...

Researchers link jellyfish, other small sea creatures to large-scale ocean mixing
The ocean's smallest swimming animals, such as jellyfish, can have a huge impact on large-scale ocean mixing, researchers have discovered. view more (2009-07-30)
Scientists map West coast areas most affected by humans
Climate change, fishing, and commercial shipping top the list of threats to the ocean off the West Coast of the United States. view more (2009-05-12)
Turtles hitchhike across the disciplines
Many species of turtle travel huge distances during their lives, especially open-water feeders such as leatherbacks. A new approach, to be presented at the Society for Experimental biology on Tuesday 1st April, combines field observations with oceanographic theories to attempt to answer some of the puzzles in open-sea turtle biology. Oceanic data... view more... (2003-03-31)
Science adopts a new definition of seawater
In Paris late last month the General Assembly of UNESCO's Intergovernmental Oceanographic Commission (IOC) accepted the case for the introduction of a new international thermodynamic description of seawater, cast in terms of a new salinity variable called Absolute Salinity. view more (2009-07-20)
Modeling of long-term fossil fuel consumption shows 14.5 degree hike in temperature
If humans continue to use fossil fuels in a business as usual manner for the next several centuries, the polar ice caps will be depleted, ocean sea levels will rise by seven meters and median air temperatures will soar 14.5 degrees warmer than current day. view more (2005-12-07)
High human impact ocean areas along US West Coast revealed
Climate change, fishing and commercial shipping top the list of threats to the ocean off the West Coast of the United States. view more (2009-05-11)
NASA study solves ocean plant mystery
A NASA-sponsored study shows that by using a new technique, scientists can determine what limits the growth of ocean algae, or phytoplankton, and how this affects Earth's climate. view more (2006-09-01)
NASA satellite detects red glow to map global ocean plant health
Researchers have conducted the first global analysis of the health and productivity of ocean plants, as revealed by a unique signal detected by a NASA satellite. view more (2009-05-29)
First buoy to monitor ocean acidification launched
The first buoy to monitor ocean acidification has been launched in the Gulf of Alaska. Attached to the 10-foot-diameter buoy are sensors to measure climate indicators. view more (2007-06-13)
Cold water gets mixed in 'blender' of Scotia Sea
The Scotia Sea, located between the Antarctic and the tip of South America, acts like a 'blender' on the very cold ocean waters that influence global ocean circulation patterns and ultimately climate, according to new research from the University of East Anglia (UEA) and published today (28 February) in the international journal Nature. The... view more... (2002-02-25)
Ocean acidification -- another undesired side effect of fossil fuel-burning
Up to now, the oceans have buffered climate change considerably by absorbing almost one third of the worldwide emitted carbon dioxide. The oceans represent a significant carbon sink, but the uptake of excess CO2 stemming from man's burning of fossil fuels comes at a high cost: ocean acidification. view more (2008-05-22)
