Toward an Improved Understanding of the Antarctic Coastal Zone and Its Contribution to Future Global Sea Level

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Understanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate and sea level. This region has multiple tipping mechanisms that could trigger large, rapid, and potentially irreversible changes in the AIS ...

Instruments and Methods: An Effective Pressure Room Seal in Ice

, 1965
Several methods were tried to seal a room in ice which could be pressurized to the overburden pressure of the ice. We found that a keyed bulkhead consisting of two ice walls with an in-place frozen mixture of water, clay and styrofoam pellets between ...

From Highlands to Henge: Refining the Provenance and Transport Pathways of Stonehenge's Altar Stone

Journal of Quaternary Science, Volume 41, Issue 6, Page 888-895, August 2026.
ABSTRACT The Altar Stone, the 6000 kg central sandstone megalith at Stonehenge in southern England, is suggested to have originated from the Orcadian Basin in northeast Scotland, some 700 km away. However, its source location within this large basin remains unresolved and its mode of transport uncertain.

Acquisition of a 3 min, two-dimensional glacier velocity field with terrestrial radar interferometry

Journal of Glaciology, 2017
Outlet glaciers undergo rapid spatial and temporal changes in flow velocity during calving events. Observing such changes requires both high temporal and high spatial resolution methods, something now possible with terrestrial radar interferometry. While

Estimating the elastic modulus of landfast ice from wave observations

Journal of Glaciology, 2023
Progress in our understanding of wave–ice interactions is currently hindered by the lack of in situ observations and information of sea-ice properties, including the elastic modulus.

Utilizing NASA's Operation IceBridge Airborne SWE and Precipitation Products to Assess Surface Snow Over Alaskan Glaciers

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Accurately estimating Snow Water Equivalent (SWE) in glacierized regions is critical for glacier modeling and mass balance analysis yet remains challenging due to sparse observations and uncertainties in precipitation products. The objectives are twofold: (a) assess how well three widely used precipitation datasets—Stage IV (a radar–gauge ...

Instruments and Methods - A novel method for obtaining very large ancient air samples from ablating glacial ice for analyses of methane radiocarbon

, 2008
We present techniques for obtaining large (similar to 100 L STP) samples of ancient air for analysis of C-14 of methane ((CH4)-C-14) and other trace constituents.

Direct measurement of optical properties of glacier ice using a photon-counting diffuse LiDAR

Journal of Glaciology, 2022
The production of meltwater from glacier ice, which is exposed at the margins of land ice during the summer, is responsible for a large proportion of glacier mass loss.

Evolution of Global Sea‐Level Rise Projections and Their Uncertainty

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract For more than 40 years, scientists have projected future sea‐level change. Documenting how sea‐level projections have evolved is vital for tracking progress, uncertainties, and future research needs. Here, we update and analyze a database of global‐mean sea level (GMSL) projections dating from 1982 to 2025, identifying five key findings. First,
