The Ob River in Central Russia

Snowy and hazy central Russia is shown in this image captured by the MODIS on the Aqua satellite on November 9, 2009. The Ob River dominates much of the image - it runs nearly diagonally across the scene. The Ob runs north and west where it is joined by the Irtysh River. The water from these rivers continues north where it empties into the Gulf of Ob, which is a long bay in the Kara Sea, which itself adjoins to the Arctic Ocean. Here is a map which shows the course the Ob River takes across Russia.

Near the bottom center right of the image, the Ob bends and makes a W shape - part of the W is just cut off by the bottom of the image. Extending southwards from this section of the Ob are long dark marks in the landscape. They are better seen in this image from 2002. These lines, which run southward to the Kazakhstan border are wetland areas along tributaries of the Ob. additional wetlands are visible in the bowls of the Ob's "w".
