Students Select EarthKAM Imagery Sites

Students participating in NASA's EarthKAM program can request photographs of specific Earth features, such as this image of South Africa, which are taken by a special camera mounted on the International Space Station when it passes over those features.

Despite Ban, Ozone-Eating Chemical Remains Prevalent

Despite Ban, Ozone-Eating Chemical Remains Prevalent

Carbon tetrachloride (CCl4), once commonly used as a cleaning agent, is a known air toxin that eats away at the ozone layer. Its production has been banned for many years, but a new CIRES and NOAA study reports those rates are still 30-100 times higher than amounts reported to emission inventories.

Landsat Satellite Spots Sunken Ships

Landsat Satellite Spots Sunken Ships

Using data from the NASA/USGS Landsat 8 satellite, researchers have detected sediment plumes extending as far as four kilometers downstream from shallow shipwreck sites, demonstrating how satellites may be used to locate the watery graves of coastal shipwrecks.

Mediterranean Drought Worst in 900 Years

Mediterranean Drought Worst in 900 Years

A new NASA study used remote-sensing and tree-ring data to conclude that the recent drought that began in 1998 in the eastern Mediterranean Levant region (Cyprus, Israel, Jordan, Lebanon, Palestine, Syria and Turkey) is likely the worst drought of the last nine centuries.

Nicaragua Volcano Continues to Erupt

Nicaragua Volcano Continues to Erupt

After more than 100 years of dormancy, Nicaragua's Momotombo volcano has erupted more than 80 times in the last three months. Momotombo rises from a chain of 19 active volcanos that run northwest to southeast in western Nicaragua, one of the most volcanically and seismically active areas on Earth.

Satellites Help Monitor Pakistani Groundwater

Satellites Help Monitor Pakistani Groundwater

After decades of unchecked pumping from underground water reservoirs, the Pakistan Council of Research in Water Resources in January 2016 began using satellite data from NASA's Gravity Recovery and Climate Experiment (GRACE) mission to create monthly updates on groundwater storage changes in the Indus River basin.
