New Antarctic seabed sonar images reveal clues to sea-level rise By British Antarctic Survey media, 11:16 AM Fri 8 May 2009
Motorway-sized troughs and channels carved into Antarctica’s continental shelves by glaciers thousands of years ago could help scientists to predict future sea-level rise according to a report in the journal Geology this month (May). ...[more]

Greenland’s ‘good news’ methane finding By CSIRO, 10:44 AM Thu 30 Apr 2009
Ice core research has revealed that a vast, potential source of the potent greenhouse gas, methane, is more stable in a warming world than previously thought. Massive quantities of methane are locked away in permafrost and in the ocean floors as methane clathrate – an ice-like material which can return to gas if temperatures increase or pressures drop. ...[more]

Parts of the Great Barrier Reef go from Doom to Boom By ARC Centre of Excellence for Coral Reef Studies, 1:09 PM Tue 28 Apr 2009
Marine scientists say they are astonished at the spectacular recovery of certain coral reefs in Australia’s Great Barrier Reef Marine Park from a devastating coral bleaching event in 2006. ...[more]

Parts of the Great Barrier Reef boom and beat the doom By ARC Centre of Excellence for Coral Reef Studies, 10:09 PM Sun 26 Apr 2009
Marine scientists say they are astonished at the spectacular recovery of certain coral reefs in Australia’s Great Barrier Reef Marine Park from a devastating coral bleaching event in 2006. ...[more]

Baby fish shaped by mothers' stress By ARC Centre of Excellence for Coral Reef Studies, 8:41 PM Tue 21 Apr 2009
Stressed reef fish mothers produce highly active babies, and this affects survival and has important implications for fish populations. A study has been undertaken that deepens our understanding of how stress affects the dynamics of wild fish populations and hence how fish may cope with increasing human-induced stresses. ...[more]

Antarctic subglacial mountain range the size of the Alps mapped By Australian Antarctic Division media, 3:37 PM Tue 21 Apr 2009
Flying twin-engine light aircraft the equivalent of three trips around the globe and working in temperatures that averaged -30 degrees Celsius, an international team of scientists has not only verified the existence of a mountain range that is suspected to have caused the massive East Antarctic Ice Sheet to form, but also has created a detailed picture of the rugged landscape buried under the ice. ...[more]

‘Ocean glider’ home after two-month voyage By CSIRO, 11:21 AM Thu 16 Apr 2009
Under the joint CSIRO Wealth from Oceans National Research Flagship and Integrated Marine Observation System (IMOS) project, the underwater ocean glider was launched in February on a two-month, 1,500 kilometre voyage. The glider’s sensors measure temperature and salinity, as well a range of biological parameters including oxygen and turbidity. ...[more]

Warming Climate impacts Food Web base in Western Antarctic Peninsula By WHOI /Rutgers University, 9:25 AM Wed 15 Apr 2009
The warming climate is changing the numbers and composition of phytoplankton—the base of the food web—along the western shelf of the Antarctic Peninsula. ...[more]

Ethanol alert: US shows Ethanol spells havoc for older boat engines By Jeni Bone, 11:29 AM Tue 14 Apr 2009
In the US two years ago a mixture of 10 percent ethanol was added to gasoline at the pump, as well as at most marine fueling stations. Now, despite innumerable reports of trouble with older engines, the EPA is seeking to up the level to 15 per cent and the marine industry is calling for a rethink. ...[more]

Support builds for a Great Barrier Reef automated reef watch By ARC Centre of Excellence Coral Reef Studies, 10:06 AM Wed 8 Apr 2009
There is strong support for developing the next generation of a high-tech sensor network to watch over the health and resilience of the vast area of Australia’s Great Barrier Reef, a new study has found. ...[more]

Proof that Marine Parks work By ARC Centre of Excellence for Coral Reef Studies, 12:32 PM Tue 31 Mar 2009
New evidence that networks of marine protected areas (MPAs) can play a big role in protecting threatened coral reef fish and other marine species from local extinction has been found by an international research team. The research was carried out in Kimbe Bay, New Britain in Papua New Guinea, a region of relatively pristine coral reefs where it is proposed to set up a network of marine reserves. ...[more]

Airborne pollutants can be toxic to marine algae By Woods Hole Oceanographic Institution (WHOI), 12:30 PM Thu 19 Mar 2009
Plankton are a critical component of Earth’s climate system: as part of their life cycle, they draw carbon dioxide out of the air and transfer it into the deep sea. A newly published paper by ocean scientists shows that airborne particles off the continents can have deadly effect on some marine phytoplankton. ...[more]

First ever whale sedation enables rescue effort By Woods Hole Oceanographic Institution (WHOI), 7:03 PM Sun 15 Mar 2009
For the first time ever, a North Atlantic right whale that had been severely entangled in fishing gear, was administered a sedation mixture that made it possible for rescuers to remove 90 percent of the entanglement. ...[more]

Being a bit 'fat' may spell the difference between life and death By ARC Centre of Excellence for Coral Reef Studies, 1:22 PM Sun 15 Mar 2009
Being a bit fat may spell the difference between life and death if you’re a coral facing a bleaching crisis. With the world’s coral reefs facing bleaching almost every year by the middle of the century as the oceans warm, a team of international scientists has revealed for the first time how corals can survive or perish in the face of the climatic onslaught. ...[more]

'So long and thanks for all the plankton,' say Antarctic whales By , 2:45 PM Fri 13 Mar 2009
The flagship German research vessel of the European Union and her science crew of 50 scientists from Germany, India, and around the world have just finished a controversial project to give iron to the Antarctic Ocean, which they claim has been depleted from the world's oceans by CO2 emissions. Here they tell the story ...[more]

Sailing for the planet - the adventures they seek By Nancy Knudsen, , 7:02 AM Tue 10 Mar 2009
David de Rothschild, a sometime polar explorer and all-round adventurer, and one of the Rothschild banking family, is in good company as an environmentalist who makes his point dramatically with his latest sailing project. ...[more]

Algae could fuel cars and jobs By CSIRO, 7:17 PM Mon 9 Mar 2009
The production of biodiesel from algae could reduce greenhouse gas emissions, help to address future fuel shortages and create jobs in rural areas. Dr Tom Beer and his team discovered the humble organisms’ green credentials during a detailed life-cycle analysis of the benefits of algal biodiesel. ...[more]

New Shark Initiatives included in Shark Meshing Program Review By NSW Minister Ian Macdonald, 11:50 AM Thu 5 Mar 2009

Natural Iron locks atmospheric carbon dioxide into the World's Oceans By WHOI Media Relations, 8:36 PM Mon 23 Feb 2009
An experiment to study the effects of naturally deposited iron in the Southern Ocean has filled in a key piece of the puzzle surrounding iron’s role in locking atmospheric carbon dioxide (CO2) in the ocean. Scientists have generally accepted the fact that biological productivity in large areas of the Southern Ocean is limited by the supply of iron, an important micronutrient for phytoplankton. ...[more]
