Feb 13, 2020Hydropower Dams Cool Rivers in the Mekong River Basin, Landsat Shows

Researchers used Landsat satellites to track changes in surface water temperature for the Sekong, Sesan and Srepok rivers. Within one year of the opening of a major dam, downstream river temperatures during the dry season dropped by up to 3.6ºF.

Dec 18, 2014From the River to the Sea

A pulse of water released down the lower reaches of the Colorado River last spring resulted in more than a 40 percent increase in green vegetation where the water flowed, as seen by the Landsat 8 satellite. The March 2014 release of water – an experimental flow implemented under a U.S.-Mexico agreement called "Minute 319" – reversed a 12-year decline in the greenness along the delta.

Dec 10, 2014Mapping Permafrost in the Alaskan Yukon River Basin

The distribution of permafrost is generally poorly mapped at regional scales. This presents a problem for resource managers and modelers trying to understand the distribution and extent of permafrost susceptible to a warming climate. To better understand permafrost’s influence on high-latitude ecosystems, researchers are developing methods to map the presence of permafrost.

Aug 29, 2013Landsat Revisits Old Flames in Fire Trends

The Wallow Fire burned over 500,000 acres, making it the largest fire in Arizona history, to date. It is one of many large fires that fire managers and researchers have seen scorch forests nationwide since the early 2000s.
