    Gusty wind and scattered rain showers across Russia’s Far East
    contributed to a heavy sediment load in the Strait of Tartary in
    mid-October 2022. The Moderate Resolution Imaging Spectroradiometer
    (MODIS) on board NASA’s Aqua satellite acquired this true-color image
    of the still-windy scene on October 14.

    The narrow Strait of Tartary (also known as Tartar Strait) lies between
    the Russian mainland (west) and Sakhalin Island (east). At its
    narrowest point, the Strait measures only 4.5 miles (7 km) in width,
    but widens as it meets both the Sea of Okhotsk, in the north, and the
    Sea of Japan (East Sea), in the south.

    This important waterway has enough depth to allow commercial vessel
    traffic, dipping to nearly 210 meters (690 feet) maximum depth, but the
    water depth is shallow in most of the Strait. Both blowing winds and
    moving tides can stir up sediment from the bottom. In addition, the
    Earth’s tenth-longest river, the Amur River, pours into the Strait. As
    the Amur travels across Mongolia, China, and Russia, it collects
    substantial sediment, which ultimately ends up in the Strait of
    Tartary.

    Satellite imagery shows heavy cloud covering Russia’s Far East,
    including the Strait of Tartary, between October 10-12. As the clouds
    cleared, increased loads of sediment became visible in the Strait.
    Heavy sediment is notably heavy on October 14, as this image reveals.
    At that time, strong wind was blowing gray-tinted smoke or dust into
    long east-to-west-oriented plumes.
