March 25, 2010 - The Rio de la Plata estuary saturated with sediment at the confluence of the Parana River and the Uruguay River. Such large amounts of sediment can often be seen in the river basin, and provide nutrients to the phytoplankton blooms that are regularly observed off the coast of Argentina. Further south, a greenish bloom of these phytoplankton is visible along the coastline. The Rio de la Plata Estuary opens up into the Atlantic Ocean and the capital cities of both countries reside along it. Buenos Aires, Argentina is visible as a semi-circular gray patch on the southwestern end and Montivideo, Uruguay is a smaller grayish patch near the north side of the opening of the estuary.
