More Greenland glaciers threatened by climate change than previously thought

Press Release— 

New maps of Greenland’s coastal seafloor and bedrock beneath its massive ice sheet show that two to four times as many coastal glaciers are at risk of accelerated melting due to climate change as previously thought.

In a new study, researchers at the University of California at Irvine (UCI), NASA and 30 other institutions have published the most comprehensive, accurate and high-resolution relief maps ever made of Greenland’s bedrock and coastal seafloor. The new study was published today in Geophysical Research Letters, a journal of the American Geophysical Union.

The top 200 meters (600 feet) of ocean water around Greenland comes from the Arctic and is relatively cold. But the water below 200 meters comes from farther south and is 3 to 4 degrees Celsius (6 to 8 degrees Fahrenheit) warmer than the water above…More

Early Results: Juno at Jupiter 

Early results from Juno's mission at Jupiter including approach to Jupiter and the first perijove pass (PJ1). Juno's scientific objectives include the study of Jupiter's interior, atmosphere and polar magnetosphere with the goal of understanding Jupiter's origin, formation and evolution. This collection of papers provides early results from Juno's measurements of the gravity and magnetic fields, deep atmospheric microwave sounding, infrared, visible and ultraviolet images/spectra and an array of fields and particles instruments as well as context for the early results with respect to current theory and models of Jupiter's formation and evolution. Topics include both Juno - Jupiter related theoretical models and data analysis as well as collaborative observations made from Earth based assets.
