Its measurements of ocean saltiness will also help scientists understand how changes in salinity affect the deep currents that drive ocean circulation.
The study combines data on waterbird use, lake measurements and invertebrate abundance to document how waterbird numbers changed over 25 years in response to the changesin lake area, salinity and food sources.
The issue is that differences in mineral content, salinity, density, and temperature all affect how the ocean reacts to, and drives, changesin weather patterns, climate variations over years or decades, ocean current circulation, etc..
