NASA has created a time series visualization of Greenland’s Helheim Glacier using 20 years of data from radar, lasers, and high-resolution cameras.
Scientists at NASA’s Goddard Space Flight Center have been experimenting with a new data product to assess groundwater and soil moisture drought indicators. The maps produced are used by the U.S. Drought Monitor and use data from NASA’s Gravity Recovery and Climate Experiment (GRACE) satellites. In 2002, the GRACE satellites were launched […]
On July 23, 1972, the first Landsat spacecraft was launched. At the time it was known as the Earth Resources Technology Satellite and it was the first satellite launched to study the earth’s landmasses. In 1975, the name was changed to Landsat. Since then, this program has been continuously monitoring changes […]
Soil moisture might not be considered a critical factor to the health of our planet but a series of satellite missions are proving otherwise. Scientists recently created maps from NASA’s Aquarius satellite of soil moisture, or the amount of water contained within soil particles, across the globe. These maps have […]
Water is essential for life on the Earth, and the supply of this precious liquid is constantly being recycled through energy from the sun. This process is known as the hydrologic cycle, and through it water is continuously exchanged between the land, the atmosphere, and the oceans. Precipitation in its […]
Ship logs contain a wealth of geographic data within them. The Old Weather Project is building a database of historical weather information extracted through crowdsourced efforts. Now, Ben Schmidt, who is an assistant professor of history at Northeastern University, has mapped out historical shipping routes. The resulting visualization looks like a jumbled […]
