Using Clouds to Map Ecosystem Boundaries

Researching clouds and their impact on ecosystems and species could help researchers find an entirely new way to see the Earth. By looking at clouds, researchers can add a layer of evidence to existing theories and practices of conservation of land and animals.

Karakoram Anomaly

This animation shows the movement of ice and debris near Panmah Glacier in Pakistan, near Central Karakoram National Park. The 17 false-color images were captured between August 1990 and July 2015 by the Thematic Mapper on Landsat 5, the Enhanced Thematic Mapper Plus on Landsat 7, and the Operational Land Imager on Landsat 8.

Using Landsat satellite data, researchers compiled videos and still pictures of glaciers from four regions in the Karakoram mountains in central Asia. Unlike other glacial regions in the world, glaciers in the Karakoram are advancing rather than retreating.

How Continents are Slowing Down Sea Level Rise

Earth's land masses have stored increasing amounts of water in the last decade, slowing the pace of sea level rise.

The continents of earth are helping slow down sea level rise, a new study shows. Melting glaciers and ice sheets are causing sea levels to change around the world, but the continents are actually absorbing a lot of this excess water.

California is Sinking Faster than Previously Thought

NASA's UAVSAR measured cumulative vertical ground movement impacting the California Aqueduct near Huron and Kettleman City from July 2013 to March 2015. The colored overlay shows areas where subsidence exceeded 7 inches (17.8 centimeters). UAVSAR pixel resolution is 20 by 20 feet (6 by 6 meters).

Researchers are tracking the changes in California’s geography from the effects of drought using a remote sensing system called interferometric synthetic aperture radar, or InSAR.
