Aral Sea, Kazakhstan and Uzbekistan. Made with Natural Earth.

What this shows

The Aral Sea lies in Kazakhstan and Uzbekistan. The Kokaral dam holds the North Aral apart from the southern basins. In these late-summer frames the western basin holds water and much of the eastern basin is pale exposed seabed. The window is 582 km by 327 km, centered at 45.4°N, 59.8°E.

Prints

Every print carries the place, the date, and the source credit on the mat, as shown. Sizes and paper are quoted with the rights and source resolution confirmed.

  1. Print preview: Satellite image from late summer 2017 of the Aral Sea: dark water in the North Aral and the western basin, with pale exposed seabed across the eastern basin.

Method and sources

Each year from 2017 to 2025 is a composite of Sentinel-2 Level-2A true color from 20 July to 30 September, read from the Microsoft Planetary Computer collection sentinel-2-l2a. The tiles are warped to one grid in UTM zone 40N at 303 m. Cloud and shadow are taken out with the scene classification layer, and a gap at a swath edge is filled from the other relative orbit. All nine years share one brightness gain, a contrast of 1.05 and a saturation of 0.85. This page shows 2017 and 2025. The scene identifiers for every year are in the machine-readable record.
