Ocean currents speed melting of Antarctic ice
Stronger ocean currents beneath West Antarctica's Pine Island Glacier Ice Shelf are eroding the ice from below, speeding the melting of the glacier as a whole, according to a new study in Nature Geoscience. A grow ...
New research points to the significant role of oceans in ancient global cooling (w/ video)
(PhysOrg.com) -- Thirty-eight million years ago, tropical jungles thrived in what are now the cornfields of the American Midwest and furry marsupials wandered temperate forests in what is now the frozen Antarctic. ...
Missing sunspots: Solar mystery solved
The Sun has been in the news a lot lately because it's beginning to send out more flares and solar storms. Its recent turmoil is particularly newsworthy because the Sun was very quiet for an unusually long ...
Crocodiles ride ocean currents to travel the high seas
University of Queensland ecologists have unlocked the mystery of how salt-water crocodiles cross large stretches of the sea despite being poor swimmers - they like to surf.
NASA Study Finds Atlantic 'Conveyor Belt' Not Slowing
(PhysOrg.com) -- New NASA measurements of the Atlantic Meridional Overturning Circulation, part of the global ocean conveyor belt that helps regulate climate around the North Atlantic, show no significant ...
Mammoth iceberg could alter ocean circulation: study
An iceberg the size of Luxembourg knocked loose from the Antarctic continent earlier this month could disrupt the ocean currents driving weather patterns around the globe, researchers said Thursday.
Study: Animals populated Madagascar by rafting there
How did the lemurs, flying foxes and narrow-striped mongooses get to the large, isolated island of Madagascar sometime after 65 million years ago?
Arctic current flowed under deep freeze of last ice age, study says
During the last ice age, when thick ice covered the Arctic, many scientists assumed that the deep currents below that feed the North Atlantic Ocean and help drive global ocean currents slowed or even stopped. ...
Rapid climate change ruled out ice age trees
Short, sharp fluctuations in the Earth's climate throughout the last ice age may have stopped trees from getting a foothold in Europe and northern Asia, scientists say.
How the ice ages ended
A study of sediment cores collected from the deep ocean supports a new explanation for how glacier melting at the end of the ice ages led to the release of carbon dioxide from the ocean.
Researchers find new source for cold ocean water abyssal layer
Ningaloo Nino: The story behind the massive 2011 Western Australia marine heatwave
(Phys.org)—Abnormal climatic conditions in the Indian and Pacific Oceans during the 2010-2011 La Niña event combined to create the extreme marine heatwave seen off the Western Australia coast in 2011, ...
Deciphering the mysterious math of the solar wind
(Phys.org)—Many areas of scientific research—Earth's weather, ocean currents, the outpouring of magnetic energy from the sun—require mapping out the large scale features of a complex system and its ...
Study says salmon may use magnetic field as navigational aid
The mystery of how salmon navigate across thousands of miles of open ocean to locate their river of origin before journeying upstream to spawn has intrigued biologists for decades, and now a new study may ...
