Project Overview

Image that Represents the Project

Aral Sea August 2000, 2010 Satellite images of the Aral Sea showing the change in size of the sea for a period of eleven years, from August 2000 through August 2010.


We analyzed NASA satellite images of the Aral Sea, making distance and area measurements to characterize changes in the size of the lake over time. We used eleven Moderate Resolution Imaging Spectroradiometer (MODIS) images, each taken in August for the years 2000 through 2010. The images also display a line that represents the 1960 shoreline of the Aral Sea. Based on the spatial resolution of the image, we set a scale so that pixels in the image represent actual kilometers on Earth. We graphed the change in distance and area measurements over time to investigate the rate of change and to predict when the Aral Sea might disappear completely. Our research has implications for other similar environmental situations.
