Use of hydrogen and oxygen isotopes to understand evaporation from enclosed waterbodies

Journal of Environmental Engineering and Landscape Management, 2022
Getting information on evaporation is important for water resource protection and managing regional enclosed waterbodies. Some lake water samples were collected in May and June from a representative enclosed waterbody – the Pearl Lake, Suzhou, China ...

The Guianese paradox: How can the freshwater outflow from the Amazon increase the salinity of the Guianan shore? [PDF]

, 2007
French Guiana is notable for the extent of its rain forests, which occupy 97% of the country, and the influence of the Amazon along its shores. In fact, the shores and estuaries support a mangrove forest typical of saline conditions.
