Scientists Explore Roots of Future Tropical RainfallWoods Hole Oceanographic Institution | 21 May 2013
A new study, published online May 19 in the journal Nature Geoscience, looks to the past to learn about the future of tropical climate change, and our ability to simulate it with numerical models.
Scientists explore roots of future tropical rainfallEurekAlert | 20 May 2013
(Woods Hole Oceanographic Institution) How will rainfall patterns across the tropical Indian and Pacific regions change in a future warming world? Climate models generally suggest that the tropics as a whole will get wetter, but the models don't always agree on where rainfall patterns will shift in particular regions within the tropics.
Sea level influenced tropical climate during the last ice ageEurekAlert | 20 May 2013
The Indo-Pacific warm pool was much dryer during the last ice age than today, because lower sea level exposed the Sunda Shelf. The large landmass, in place of the warm ocean, altered the atmospheric circulation, shifting convection further west into the Indian Ocean.
Conservationists to count breeding birds after 'puffin wreck' winterGuardian Unlimited | 17 May 2013
Nipped fingers and handfuls of guano will be the order of the day for wildlife rangers on the Farne Islands as they embark on an epic census on Friday to discover whether puffin numbers have plummeted after a year of extreme weather. The 10 National Trust rangers living on the islands must dangle their bare fingers down 60,000 puffin burrows in the next two months to determine whether breeding pairs have fallen after the worst puffin "wreck" for 66 years.
Corals turn to algae for stored food when times get toughEurekAlert | 16 May 2013
(Ecole Polytechnique Fédérale de Lausanne) Researchers at EPFL present new evidence for the crucial role of algae in the survival of their coral hosts. Ultra-high resolution images reveal that the algae temporarily store nutrients as crystals, building up reserves for when supplies run low.
A Book Blooms in the LabWoods Hole Oceanographic Institution | 16 May 2013
When conditions of light and nutrients align in the surface waters of the ocean, tiny single-celled algae called phytoplankton respond with explosive growth and reproduction in a phenomenon known as a phytoplankton bloom.
Using earthquake sensors to track endangered whalesEurekAlert | 14 May 2013
(University of Washington) Oceanographers analyzed more than 300,000 fin-whale calls recorded by seafloor seismometers and recreated more than 150 fin-whale paths off the Pacific Northwest coast.
Scientists find impact of open-ocean industrial fishing within centuries of bird bonesEurekAlert | 14 May 2013
(Smithsonian) The impact of industrial fishing on coastal ecosystems has been studied for many years. But how it affects food webs in the open ocean has not been very clear. So a team of Smithsonian and Michigan State University scientists and their colleagues looked to the ancient bones of seabirds for answers, revealing some of the dramatic changes that have happened within open-ocean food webs since the onset of industrial fishing.
Arctic expedition to study impact of climate change on planktonGuardian Unlimited | 14 May 2013
The goal of the 25,000km Tara Oceans Polar Circle Expedition, with some 15 scientist on board, is to search for planktonic organisms, including viruses, bacteria, protists and metazoans, all vital resources that need to be studied in their own environment while there is still time.
Groundbreaking video technology to improve stock surveysWorld Fishing | 14 May 2013
A new method of using video data collection to improve groundfish and flat fish stock surveys has been developed, which is showing promise to improve accuracy by increasing spatial coverage and to allow the conducting of surveys without fish mortality.
Little justification for MSY approachWorld Fishing | 13 May 2013
Fishing to maximum sustainable yield (MSY), which is an integral part of the EUs revised Common Fisheries Policy (CFP), has little justification, according to Ian Boyd, Defras chief scientific adviser.
Coral reefs suffering, but collapse not inevitable, researchers sayEurekAlert | 10 May 2013
(Cell Press) Coral reefs are in decline, but their collapse can still be avoided with local and global action. That's according to findings reported in the Cell Press journal Current Biology on May 9 based on an analysis that combines the latest science on reef dynamics with the latest climate models.
