Understanding High-Latitude Methane in a Warming Climate
Climate change could spur greenhouse gas release from the Arctic. A new project will synthesize existing data to improve uncertain predictions.
NSF’s Budget Details Provide Some Good News for the Geosciences
The budget features significant funding for polar region science, including efforts to document and understand rapid changes in the Arctic and to modernize Antarctic infrastructure.
Arctic Is Experiencing a Warmer “New Normal,” NOAA Reports
The acting head of the National Oceanic and Atmospheric Administration, Timothy Gallaudet, says the Trump administration is addressing the findings of the agency’s latest annual update on the Arctic.
Reducing Errors in Satellite-Derived Arctic Sea Ice Thicknesses
Salty snow throws off satellite-based estimates of Arctic sea ice thickness by up to 25%. A new method seeks to fix that.
Satellites Accurately Capture Ocean Salinity in the Arctic
On-the-ground measurements are notoriously difficult in the harsh environment of the Arctic, but satellites could help close the gap in measuring sea surface salinity.
Map Provides High-Resolution Look at Nearly Entire Arctic Region
Researchers highlight the value of the time element incorporated into imagery and having a baseline for revisiting and comparing topography.
