Novel Record of Intermittent Grounding of the Venable Ice Shelf Since 1935 From Operation IceBridge Airborne‐Gravity‐Derived Bathymetry and Landsat Imagery

open access: yesGeophysical Research Letters, Volume 52, Issue 9, 16 May 2025.
Abstract Future projections and past reconstructions of Antarctic Ice Sheet stability and sea‐level rise depend on knowledge of continental shelf bathymetry, which controls water circulation under floating ice and interactions between the ice shelf and seafloor.

ASSESSING THE RISKS OF A FUTURE RAPID LARGE SEA LEVEL RISE: A REVIEW [PDF]

open access: yes
Our aim is to make an appropriate characterization and interpretation of the risk problem of rapid large sea level rise that reflects the very large uncertainty in present day knowledge concerning this possibility, and that will be useful in informing ...

Modeling the Impacts of Antarctic Sea Ice Decline: Responses of Atmospheric Dynamics

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 9, 16 May 2025.
Abstract Rapidly changing climate in polar regions not only impacts their local environments but also influences weather patterns in tropical and mid‐latitude regions. A key indicator of these changes is the accelerated decline of sea ice in polar areas.

Satellite‐Estimated Microwave Emissivity and Emission Temperature Over the Arctic Sea Ice: ANN‐Based Algorithm

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 9, 16 May 2025.
Abstract Satellite microwave surface‐sensitive sounding channels have long faced limitations in polar data assimilation (DA) due to difficulties in specifying radiative boundary conditions over sea ice, particularly during winter. Previous studies have proposed using outputs from sea‐ice growth model to estimate microwave emissivities and emission ...

Solar Cycle Detected in Natural Tritium of Ice Layers Before the Nuclear Era

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 9, 16 May 2025.
Abstract The 11‐year cycle of the solar activity affects the production rate of cosmogenic isotopes. For tritium in precipitation, it has been just recently proven that this link exists. Here we show, for the first time, a tritium ice core time series which extends back to 1923, covering a time period that avoids the presence of artificial tritium from
