The Bohai Sea, China
This image, captured by the MODIS on the Terra satellite, on February 27, 2008, shows the Bohai Sea, in China. The Bohai Sea, the body of water on the right side of the image, is actually a gulf of the Yellow Sea. It is located on the coast of northeastern China.
The Bohai Sea (also sometimes referred to as the Bohai Gulf or Bay, or just the Bo Hai) is clouded by thick sediment which colors it brown. The rivers of northeast China all spill sediment into the Bo Hai. The Yellow River in particular carries dust from the Gobi Desert of Inner Mongolia down through the North China Plain, before pouring into the Bo Hai. The Yellow River is visible as a whitish line near the bottom right center of the image. It is just below the red dot (the location of an active fire).
The light brown region that surrounds the Bohai Sea on the west is the North China Plain. The plain is bordered on the north by the Yanshan Mountains and on the west by the Taihang Mountains. To the south, it merges into the Yangtze Plain. The city of Beijing is visible - it is at the foot of the mountains on the northwest "corner" of the North China Plain. It's slightly gray in color and circular in shape.
