A global characterization of mantle flow patterns beneath active oceanic transforms suggests pervasive upwelling stabilizes divergent plate boundaries by warming and weakening these enigmatic features.
Oceans
Chaos Beneath a Calm Sea
Seismic data help reveal fine-scale wave breaking, instability and turbulence in the ocean interior.
One of World’s Oldest Animals Records Ocean Climate Change
Researchers probe millennia-old deep-ocean sponges for links between ocean nutrients and climate.
New Postage Stamps Focus on Bioluminescent Marine Life
The stamps help draw attention to the wonders of creatures that generate their own light and to the environmental problems that threaten them in marine habitats, scientists say.
Ocean Tides Affect Ice Loss from Large Polar Ice Sheets
A recent paper in Reviews of Geophysics discusses how ocean tides affect the motion of, and loss of ice from, the Antarctic and Greenland ice sheets.
A Novel Approach to a Satellite Mission’s Science Team
NASA’s Plankton, Aerosol, Cloud, Ocean Ecosystem satellite mission, still in planning stages, operates with a framework that could serve as an example for science support of future missions.
Acoustic Imaging of Oceanic Mixing in the Gulf of Mexico
Detailed analysis of acoustic reflections suggests that vertical mixing of oceanic water is enhanced at greater depths, thanks to weak stratification and the roughness of the seabed.
Ocean Wind Satellites Observe an Amazonian Drought
Satellites designed to observe ocean winds can also be used to map both forest structure and water content, allowing researchers to disentangle factors of carbon loss due to drought in the Amazon.
Tyler Prize Honors Two Leaders in Marine and Climate Science
Biological oceanographers Paul Falkowski and James McCarthy helped revolutionize the world’s understanding of Earth’s changing climate, both past and present.
AGU Editor Picks for 2018 Ocean Sciences Meeting
Recommendations from AGU’s journal editors of some of the most interesting paper and poster sessions at this year’s Ocean Sciences Meeting.
