The Arctic has been losing sea ice over the past several decades as Earth warms. However, each year, as the sea ice starts to melt in the spring following its maximum wintertime extent, scientists still struggle to estimate exactly how much ice they expect will disappear through the melt season. Now, a new NASA forecasting model based on satellite measurements is allowing researchers to make better estimates.
It doesn’t matter where you get your weather forecast. With the newest weather satellite in orbit, prediction models will probably improve overnight. The GOES-R satellite was launched from Cape Canaveral on Saturday afternoon atop an Atlas V 541 rocket. It’s the first of three satellites being built to replace the aging United States weather satellite system.
Few regions of the world are as unstable in the face of advancing climate change as frozen West Antarctica, where rapidly melting glaciers have scientists on edge about the potential for huge amounts of future sea-level rise. Now, a new study has pinpointed some of the most rapid ice losses observed in the region in the past 15 years — and it supports a growing scientific belief that warm ocean water is behind the melting.
Coral reefs have almost always been studied up close, by scientists in the water looking at small portions of larger reefs to gather data and knowledge about the larger ecosystems. But NASA’s Jet Propulsion Laboratory is taking a step back and getting a wider view, from about 23,000 feet above.
Scientists think they see evidence of two huge tsunamis having once swept across the surface of Mars.
A recent 14-year dry spell in the Middle East was the worst drought in the past 900 years, according to a new NASA study released this week.
Astronomers using some of the world’s most powerful telescopes have determined that an ocean at least a mile deep covered a significant fraction of the Martian surface four billion years ago.
Globally, soils hold a tiny fraction of Earth’s water. But that moisture is nevertheless a crucial quantity in water, carbon, and energy cycles.
BOEM, NASA and NOAA to Participate in Monitoring Projects
(From BOEM) — The Bureau of Ocean Energy Management (BOEM) plans to join NASA and the National Oceanic and Atmospheric Administration (NOAA) in supporting an initiative that …
Arctic sea ice coverage continued its below-average trend this year as the ice declined to its annual minimum on Sept. 17, according to the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado, Boulder.
UMass Dartmouth’s School for Marine Science & Technology (SMAST) has received $228,000 from NASA to continue its collaborative project to discover how coastal waters store and remove carbon dioxide (CO2) from the atmosphere.
Sea ice in summer looks dramatically different than sea ice in winter, even in the polar Arctic. Summer snowmelt, pools of water on thinning ice and exposed ocean replace vast winter expanses of white snow-covered ice — and this weekend NASA’s high-flying laser altimeter begins a campaign to investigate these features.
