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

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 ...

Glaciological and Chemical Characteristics of an Antarctic Inland Plateau (Abstract) [PDF]

Annals of Glaciology, 1988
A glaciological research project in east Queen Maud Land, Antarctica, has been carried out by the Japanese Antarctic Research Expeditions between 1982 and 1986 (JARE-23 – JARE-27).In this paper, we deal with the area traversed by JARE-25 and JARE-26, a representative inland plateau in Antarctica.

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

Five decades of strong temporal variability in the flow of Brunt Ice Shelf, Antarctica

Journal of Glaciology, 2017
Data showing velocity changes on the Brunt Ice Shelf (BIS), Antarctica, over the last 55 years are presented and analysed. During this period no large-scale calving events took place and the ice shelf gradually grew in size. Ice flow velocities, however,

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 ...

A 700 year record of Southern Hemisphere extratropical climate variability [PDF]

, 2004
Annually dated ice cores from West and East Antarctica provide proxies for past changes in atmospheric circulation over Antarctica and portions of the Southern Ocean, temperature in coastal West and East Antarctica, and the frequency of South Polar ...

Combining morphological and molecular data to study past foraminiferal communities from a temperate coastal sediment core

Boreas, Volume 55, Issue 1, Page 198-215, January 2026.
This paper presents the results of a dual approach for assessing fossil benthic foraminiferal communities using both traditional morphology‐based analyses and sedimentary ancient DNA (sedaDNA) metabarcoding. The main objectives are to test the feasibility of sedaDNA analyses to assess foraminiferal biodiversity in temperate shelf sediments (Le Croisic,

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.
