    On March 8, 2022. The Moderate Resolution Imaging Spectroradiometer
    (MODIS) on board NASA’s Aqua satellite acquired a true-color image of
    muddy water pouring into the Río de la Plata, a funnel-shaped estuary
    that sits between Uruguay (north) and Argentina (south) and connects
    with the South Atlantic Ocean. The silt-laden Paranà River separates
    into multiple channels as it courses through the large labyrinth of
    trees and marsh known as the Paranà River Delta. The Paranà River
    carries most of the sediment into the Río de la Plata, and also
    provides about three-quarters of the fresh water that flows into the
    estuary. Topsoil running off agricultural fields and flowing into the
    Paranà as a result of rainstorms likely produced the heavy load of
    brown sediment carried by this river.

    The other major river feeding Río de la Plata is the Uruguay River,
    which can be seen flowing from the north, carrying very little
    sediment. The large area of gray sitting on the southern coast of the
    Río de la Plata marks the city of Buenos Aires, the capital and largest
    city of Argentina.
