Aging snow is making Greenland darker, warmer

American Geophysical Union Researcher Gabriel Lewis measures reflectivity on Greenland’s ice sheet during a 2016 research expedition. A reduction in fresh snowfall has caused parts of Greenland to become darker and may lead to additional surface melt, according to a new study. Credit: Forrest McCarthy A lack of fresh snow is darkening Greenland’s surface, likely contributing to faster melting. The snow shortfall is a consequence of a persistent weather system that blocks precipitation and warms temperatures over the ice sheet interior, a new study finds. The Greenland Ice Sheet has warmed 2.7 degrees Celsius (4.85 degrees Fahrenheit) since 1982. It is experiencing the greatest melt and runoff rates in at least the last 450 years, and likely the greatest rates in the last 7,000 years, according to the authors of the new study, published today in Geophysical Research Letters, AGU’s journal for high-impact, short-format reports with immediate implications spanning all Earth an

Kaarta and EXI Join Forces to Address UXO Positioning in Challenging GNSS-Denied Environments

Kaarta and EXI Join Forces to Address UXO Positioning in Challenging GNSS-Denied Environments Share Article Technician scanning for UXO on steep terrain in wooded GPS-denied area. It’s exciting when a combination of technologies come together to address such a significant problem as locating UXO in the most challenging of environments. PITTSBURGH, and AUSTIN, Texas (PRWEB) May 14, 2021 Kaarta, the innovator of real-time mobile 3D reality capture, and Exploration Instruments LLC (EXI), the experts in near-surface geophysical equipment and applications, announced today a joint collaboration and distribution agreement to address the needs of the Unexploded Ordnance (UXO) and geophysical industry. EXI now offers rental, sales, and training for Kaarta s SLAM-based mobile mapping systems and the integration with geophysical equipment such as Digital Geophysical Mapping (DGM) and Advanced Geophysical Classification (
