Food security threatened by sea-level rise

Coastal countries are highly prone to sea-level rise, which leads to salt-water intrusion and increased salinity levels in agricultural land. Also typical for these regions are floods and waterlogging caused by cyclones and ...

Salty oceans can forecast rain on land

At this week's American Geophysical Union meeting, a team of researchers from the Woods Hole Oceanographic Institution (WHOI) presented their latest research findings on the long-range predictions of rainfall on land. Their ...

The life cycle of a flood revealed

A NASA analysis of a 2015 Texas flood is the first to document the full life cycle and impacts of a flood on both land and ocean. Using data from NASA's Soil Moisture Active Passive (SMAP) satellite and other satellite instruments, ...

Freshening of Southern Ocean linked to moving sea ice

(Phys.org)—A team of researchers from Switzerland and Germany has found evidence that suggests the reason that the Southern Ocean has become less salty over the past few decades is because sea ice has been moving differently. ...

Global warming's next surprise: Saltier beaches

Batches of sand from a beach on the Delaware Bay are yielding insights into the powerful impact of temperature rise and evaporation along the shore that are in turn challenging long-held assumptions about what causes beach ...

Soil increasingly at risk from household products

Changing Australian soil conditions are exposing crops to silver nanoparticles, which are widely used in household products, a study led by The University of Queensland has found.

Image: Root-zone soil moisture map

ESA's SMOS mission was launched in 2009 to provide global observations of soil moisture and ocean salinity – two important variables in Earth's water cycle. While this novel Earth Explorer satellite continues to advance ...

Study offers clues to better rainfall predictions

The saltiness, or salinity, of seawater depends largely on how much moisture is pulled into the air as evaporative winds sweep over the ocean. But pinpointing where the moisture rains back down is a complicated question scientists ...
