Intensification of the Southern Hemisphere westerly winds during the last deglaciation (18.5–14.0 cal ka BP): Evidence from Pearly Beach wetland on the southern Cape coast of South Africa

Journal of Quaternary Science, Volume 41, Issue 1, Page 25-35, January 2026.
ABSTRACT The southwestern Cape of South Africa experiences a complex and dynamic climate, shaped by the interplay between the temperate Southern Hemisphere westerly winds and the subtropical easterlies. Despite the climatic sensitivity of the region, relatively few studies have examined how conditions have varied since the last deglaciation in response

Mechanical analysis of pinning points in the Ross Ice Shelf, Antarctica

Annals of Glaciology, 2019
Ice shelves regulate the rate of ice-sheet discharge along much of the Antarctic coastline. Pinning points, sites of localised grounding within floating ice, can in turn, regulate the flow and thickness of an ice shelf.

The Grounding of an Ice Shelf in the Central Arctic Ocean: A Modeling Experiment [PDF]

, 2003
A numerical ice sheet model was used in a first test towards evaluating the hypothesis that, during a period of large-scale glaciation, an ice shelf emanating from the Barents/Kara Seas grounded across parts of the Lomonosov Ridge to a depth of around ...

Morphology of Antarctic Polygons and Implications for Polygon Evolution and Subsurface Ice Dynamics

Permafrost and Periglacial Processes, Volume 37, Issue 1, Page 143-153, January/March 2026.
ABSTRACT Polygonal terrain results from thermal contraction, is commonly found in periglacial environments, and serves as a valuable proxy for interpreting subsurface ice distribution and climate history on Earth and Mars. In this study, we investigate the morphology of polygons in Beacon Valley, Antarctica, to assess the relationship between polygon ...

The Evolving Decline of Landfast Sea Ice in Northern Alaska and Adjacent Waters: Results from an Updated Climatology

Journal of Geophysical Research: Oceans, Volume 131, Issue 1, January 2026.
Abstract We present a new 27‐year record of landfast sea ice extent in northern Alaska and adjacent waters, which uses ice chart data to extend a previous analysis based on synthetic aperture radar (SAR) imagery. This new climatology provides updated information on the decline of landfast ice in a region of the Arctic that has seen extensive losses of ...

Slip‐Event Timing and Ice Velocity Vary at Long‐Period Ocean Tidal Frequencies at Whillans Ice Plain, West Antarctica

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 1, January 2026.
Abstract Whillans Ice Plain (WIP), a region of West Antarctica flowing into the southern Ross Sea, lurches forward 0.2–0.6 m over 30–60 min once or twice per diurnal ocean tidal cycle. Combining 11 years (2008–2019) of 30 s or better resolution Global Navigation Satellite System (GNSS) data from past field campaigns is necessary to provide insight into

A comparison of automated approaches to extracting englacial-layer geometry from radar data across ice sheets

Annals of Glaciology, 2020
Radar surveys across ice sheets typically measure numerous englacial layers that can often be regarded as isochrones. Such layers are valuable for extrapolating age–depth relationships away from ice-core locations, reconstructing palaeoaccumulation ...

Ice Phenology and Thickness in Small Arctic Lakes: Field Observations and Mechanistic Controls

Water Resources Research, Volume 62, Issue 1, January 2026.
Abstract The Arctic is the fastest‐warming region globally. Lake ice is a sentinel indicator of Arctic change, with wide impacts on hydrological regimes, biodiversity, and ecosystem services. While small lakes are ubiquitous across northern boreal and tundra zones, ice observations remain biased toward large lakes with distinct freezing and melting ...

Surface velocity fluctuations for Glaciar Universidad, central Chile, between 1967 and 2015

Journal of Glaciology, 2016
For the Andes Cordillera, where observed mass-balance records are sparse, long-term glacier velocity measurements potentially represent a useful tool for assessing glacier health.
