Regional variability of diatoms in ice cores from the Antarctic Peninsula and Ellsworth Land, Antarctica [PDF]

open access: yesThe Cryosphere, 2022
The presence of marine microfossils (diatoms) in glacier ice and ice cores has been documented from numerous sites in Antarctica, Greenland, as well as from sites in the Andes and the Altai mountains, and attributed to entrainment and transport by winds.

Regional validation of the use of diatoms in ice cores from the Antarctic Peninsula as a Southern Hemisphere westerly wind proxy [PDF]

open access: yesClimate of the Past, 2022
The Southern Hemisphere westerly winds are among the most important drivers of recently observed environmental changes in West Antarctica. However, the lack of long-term wind records in this region hinders our ability to assess the long-term context of ...

Dynamic Anti‐Icing Surfaces (DAIS) [PDF]

open access: yesAdvanced Science, 2021
AbstractRemarkable progress has been made in surface icephobicity in the recent years. The mainstream standpoint of the reported antiicing surfaces yet only considers the ice–substrate interface and its adjacent regions being of static nature. In reality, the local structures and the overall properties of ice–substrate interfaces evolve with time ...

The contribution of melt ponds to enhanced Arctic sea-ice melt during the Last Interglacial [PDF]

open access: yesThe Cryosphere, 2021
The Hadley Centre Global Environment Model version 3 (HadGEM3) is the first coupled climate model to simulate an ice-free Arctic during the Last Interglacial (LIG), 127 000 years ago.

Physical properties of shallow ice cores from Antarctic and sub-Antarctic islands [PDF]

open access: yesThe Cryosphere, 2021
The sub-Antarctic is one of the most data-sparse regions on earth. A number of glaciated Antarctic and sub-Antarctic islands have the potential to provide unique ice core records of past climate, atmospheric circulation, and sea ice. However, very little

Ice Core Chronologies from the Antarctic Peninsula: The Palmer, Jurassic, and Rendezvous Age-Scales

open access: yesGeosciences, 2022
In this study, we present the age scales for three Antarctic Peninsula (AP) ice cores: Palmer, Rendezvous, and Jurassic. The three cores are all intermediate-depth cores, in the 133–141 m depth range.

Decadal Scale Variability of Larsen Ice Shelf Melt Captured by Antarctic Peninsula Ice Core

open access: yesGeosciences, 2022
In this study, we used the stable water isotope record (δ18O) from an ice core drilled in Palmer Land, southern Antarctic Peninsula (AP). Utilizing δ18O we identified two climate regimes during the satellite era.

Stochastic ice stream dynamics [PDF]

open access: yesProceedings of the National Academy of Sciences, 2016
Significance Ice streams form the backbone of the flow field of ice sheets. They are known to exhibit a complex spatiotemporal dynamics, which is largely not well understood. Understanding the controls on such dynamics is crucial to sea level change projections as well as to the interpretation of paleorecords.

An Unprecedented Sea Ice Retreat in the Weddell Sea Driving an Overall Decrease of the Antarctic Sea‐Ice Extent Over the 20th Century

open access: yesGeophysical Research Letters, 2023
Sea‐ice extent is predicted to decrease in a warming climate. However, despite global warming over the past century, total Antarctic sea ice remained relatively stable from 1979 until 2015, before strongly melting.
