NASA and the United States Geological Survey’s (USGS) Landsat 8 satellite captured images of the Mekong river before and after it turned from its signature brown to an unusual aquamarine color. According to authorities, it is possible for the green color to persist until the flood season.
Brown To Green
The Operational Land Imager on the Landsat 8 captured images of the Mekong river near the town of Huay Xai in Laos. Compared to the 2015 image where the Mekong was still brown, the latest image of the same area shows that the Mekong had turned somewhat blue-green.
