Satellite Record Gives Unprecedented View of Changing Antarctic Ice Melt Pattern over 25 Years

Scripps News (August 10th 2020)

Using 25 years of satellite data, a new paper by lead author Susheel Adusumilli provides "convincing evidence" that changes in the Southern Ocean are driving Antarctic ice loss. The authors also constructed the longest and most comprehensive record of ice sheet melting in Antarctica, describing the unique changing environment across both Antarctic ice sheets.

New research: Viscous and elastic buoyancy stresses as drivers of ice-shelf calving

Cambridge University Press (June 3rd 2020)

A new paper written by Cyrille Mosbeux, Till J.W. Wagner, Maya K. Becker, and Helen A. Fricker describes the elastic and viscous driving forces of ice-shelf calving. Developing these effects allows for better modeling and prediction of future mass loss from the ice sheets.

NASA Space Laser Missions Map 16 Years of Ice Sheet Loss

NASA (April 30th 2020)

"Using the most advanced Earth-observing laser instrument NASA has ever flown in space, scientists have made precise, detailed measurements of how the elevation of the Greenland and Antarctic ice sheets have changed over 16 years." The new findings track the large-scale mass loss of ice sheets with the laser altimetry ICESat-2 satellite launched in 2018.

Scripps Researcher in Antarctica Fights Time, the Elements to Reach Planet’s Oldest Ice

Times of San Diego (November 26th 2019)

Polar Center researcher Jeff Severinghaus and colleagues recently traveled to Antarctica to sample the oldest ice on the continent. With an improved drilling system, the team are hoping to acquire ice core climate records stretching further back than ever before.
