Increasing the Glen–Nye Power‐Law Exponent Accelerates Ice‐Loss Projections for the Amundsen Sea Embayment, West Antarctica

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract Glacier flow is typically modeled using a power‐law rheology known as the Glen–Nye flow law, with the power n $n$ assumed to be 3. However, recent research and past observations suggest that n=4 $n=4$ may better represent ice flow in some locations.

Can Biogeochemical Tracer Observations Constrain Southern Ocean Diapycnal Mixing Rates?

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract Direct observations of background diapycnal mixing rates in the Southern Ocean (SO) are limited spatially and temporally, making the choice of an appropriate value to parameterize this mixing in Earth system models a challenge. However, the deployment of Argo floats throughout the SO has provided an extensive range of observations of both ...

Rapid Changes in Retrogressive Thaw Slump Dynamics in the Russian High Arctic Based on Very High‐Resolution Remote Sensing

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract We used very high‐resolution satellite images to map the development of retrogressive thaw slumps (RTS) at six sites in the Russian High Arctic for the period 2011 to 2020. The 3,466 mapped RTS revealed an overall high activity, with site‐specific increases of RTS‐affected area up to +2,700% and RTS numbers up to +1,294%.

Assessing the Duration of the Paleocene‐Eocene Thermal Maximum

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract The Paleocene‐Eocene Thermal Maximum (PETM) was a climate/carbon cycle perturbation recognized in stable carbon isotope (δ13C) records with a negative carbon isotope excursion (CIE). The PETM CIE termination has been associated with a δ13C inflection with pre‐PETM‐like values referred to as the G point.
