Scripps Institution of Oceanography is one of five research institutions to assist in the creation of the new Global Ocean Biogeochemistry Array, an NSF-funded expansion of biogeochemical ocean monitoring with autonomous floats. “It’s an evolution of how we’re observing the ocean,” says Lynne Talley, Scripps professor and co-principal investigator on the project. Scripps scientists will be building new floats and coordinating their deployments, producing readily-available data for researchers across the globe.

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.

After returning from the exploration vessel Polarstern amidst the Covid-19 pandemic, researcher Jeff Bowman shares his experience in the MOSAiC expedition, studying phytoplankton photosynthesis in the Arctic sea ice region.
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 (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.

Using new data from the NASA ICESat-2 satellite, researchers found that the Antarctic and Greenland ice sheets are melting at an unprecedented rate of 318 gigatons per year, greatly contributing to future sea level rise.

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.

Helen Fricker predicted that the Amery Ice Shelf would calve its “Loose Tooth” by 2015. The day after Amery calved D28, Fricker spoke to the BBC about the event and her earlier prediction. Though it remains “wobbly,” Amery shed a much larger iceberg, D28, which Fricker described as being “the molar compared to a baby tooth.” While this event is unrelated to climate change, “there is no cause for alarm yet for this particular ice shelf,” Fricker added.
