PROBA-V Monitors Coastal Waters

The Caspian Sea is the Earth’s largest inland water body with an area of 371,000 km². It became land-locked by regional tectonic uplift and sea level decrease about 5.5 million years ago and is largely replenished by the Volga and Ural rivers, that both discharge into the sea’s northern part. As a result of the incoming fresh water, the northern part’s salinity is lower.
PROBA-V observations are increasingly used for water quality applications, such as information on chlorophyll concentration and water-suspended materials. The 100 m false-colour image of 8 March 2016 shows a potential application, with high Atrak river sediment concentrations that can be recognised by light-blue taints along the south-eastern Caspian coast.
Further, the lower image part shows snow-covered peaks from the Alborz mountain range, while in the lower-right corner the Haj Aligholi Salt Lake is partly visible in white.
