Satellites Accurately Capture Ocean Salinity in the Arctic
On-the-ground measurements are notoriously difficult in the harsh environment of the Arctic, but satellites could help close the gap in measuring sea surface salinity.
Ocean Dynamics May Drive North Atlantic Temperature Anomalies
A new analysis of sea surface temperature and salinity over several decades seeks to settle the debate on which of two mechanisms underlies the Atlantic Multidecadal Oscillation.
Observing Mercury’s Brilliant Flares from Earth
Researchers make the first short-term observation of sodium flares in Mercury’s exosphere.
Preventing Climate Change by Increasing Ocean Alkalinity
A recent paper in Reviews of Geophysics discussed increasing ocean alkalinity as an alternative method of carbon sequestration in response to climate change.
Salinity Monitoring Gives Insight into the Global Water Cycle
Salinity and Water Cycle over the Oceans: Recent Progress and Future Challenges; Hamburg, Germany, 12–15 October 2015
Electrical Concrete Offers Green Alternative to Airport Deicers
The Federal Aviation Administration is testing conductive concrete as a replacement for water-polluting chemicals used to melt ice from airport tarmacs.
Salty Secret Might Aid Carbon Impact of Restored Wetlands
Research on a surprising way rainfall affected the salinity of a boreal peatland might help restorers of such wetlands wrecked by tar sands mining maximize carbon absorption of reclaimed marshes.
Satellite Salinity Data Improves Gulf Stream Eddy Detection
A pronounced contrast in salinity between the Gulf Stream and current rings makes satellite salinity measurements valuable.
