“It’s really by stepping back and looking at the Earth, observing these changes in their context from space, can we really understand what’s happening.”

“Our new interface specifically uses Landsat to track flow velocity fields of Greenland’s outlet glaciers and how they have changed over time.”

“The Landsat program has produced an unmatched record of observational coverage of Earth’s surface extending back to 1972, offering stunning satellite views of landscapes all over the world. This collaboration between NASA and the U.S. Geological Survey (USGS) has also yielded more than five decades of scientific discoveries as Earth’s climate has changed.”

“[H]ope for the future comes from looking at the past. For more than five decades, Landsat satellites, developed by NASA and operated by the United States Geological Survey, have captured a wide range of information about the world’s land and water resources. They provide us access to a rich archive of imagery that shows how we can better manage and capitalize our land, driving sustainable increases in productivity and profitability.”

“There is no other asset in the sky that can show us what Landsat does in terms of the effect of this eruption and also the effect of recovery following the eruption.”

“The novelty of our study lies in the bigger picture—measuring glacier change over all main glaciated ranges in Bolivia—and in the identification of potentially dangerous lakes for the first time.”

“Landsat is key to a wide range of applications that support global glacier monitoring and elucidate the impacts of global climate change.”

“Because of Landsat’s global purview and long history, it has become a reference point for all Earth observation work and is considered the gold standard of natural resource satellite imagery.”
