Tracking ocean salinity from space using colour

Measuring salinity at the ocean's surface is important for tracking global ocean circulation as well as local ecosystem health. A research team from Universiti Malaysia Terengganu have proposed a new method to measure sea ...

Tolerance to saltwater and freshwater is key to survival

According to Charles Darwin the ability to adapt to new conditions is essential for survival of species. The capacity to cope with altered conditions is becoming increasingly important in the face of climate change. New evidence ...

Inexpensive and stable—The salt water battery

Water could form the basis for future particularly inexpensive rechargeable batteries. Empa researchers have succeeded in doubling the electrochemical stability of water with a special saline solution. This takes us one ...

Scientists warn that saline lakes in dire situation worldwide

Saline lakes around the world are shrinking in size at alarming rates. But what—or who—is to blame? Lakes like Utah's Great Salt Lake, Asia's Aral Sea, the Dead Sea in Jordan and Israel, China's huge Lop Nur and Bolivia's ...

Genetic key to salt-tolerance discovered in tilapia fish

Most fish live either in fresh water or salt water, but others, including tilapia, have the remarkable ability to physiologically adjust to varying salinity levels—a trait that may be critically important as climate change ...

A crab's eye view of rising tides in a changing world

Coastal ecosystems and aquifers will be greatly affected by climate change, not only from rising temperatures and more volatile weather, including changes in precipitation patterns, but also from sea level rise.

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 ...

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 ...
