ISS028-E-044444 (8 Sept. 2011) --- This image, photographed by an Expedition 28 crew member on the International Space Station, highlights a sand dune field within the Burqin-Haba River-Jimunai Desert near the borders of China, Mongolia, Russia and Kazakhstan. The dune field (approximately 32 kilometers long) is located immediately to the west-northwest of the city of Burqin (not shown), and is part of the Junggar Basin, a region of active petroleum production in northwestern China. The Irtysh River, with associated wetlands and riparian vegetation (appearing grey-green in the image) flows from its headwaters in the Altay Mountains to the east towards Siberia to the west (right to left). Tan sandy linear dunes at center on the south side of the Irtysh River dominate the view. The linear dunes are formed from mobile barchan (crescent-shaped) dunes moving from left to right in this view; the barchans eventually merge to form the large linear dunes some of which reach 50-100 meters in height. Sand moving along the southern edge of the dune field appears to be feeding a southeastern lobe with a separate population of linear dunes (lower right). The Burqin-Haba River-Jimunai Desert area also includes darker gravel covered surfaces that form pavements known locally as gobi. These are somewhat indistinguishable from vegetated areas arresting some of the dunes at the resolution of the image, but tend to be located on the flat regions between the dunes.
