On ice floe across the Weddell Sea (thirty years since the opening of the first Antarctic drifting station)

Лëд и снег, 2022
The year 2022 marks the 30th anniversary from operation of the Russian-American drifting station in the Antarctic. It was first experience of organizing a research station on sea ice in the South Polar exploration. Russia and the U.S.

A Roadmap for Using Hybridisation Capture-Based Target Enrichment of Ancient Environmental DNA in Palaeoecology. [PDF]

Mol Ecol Resour
ABSTRACT Recovering ancient DNA from environmental samples is transforming the way we understand historical ecosystems. While high‐throughput sequencing of the total DNA in environmental samples (shotgun metagenomic sequencing) reveals the taxonomic contents of these samples, the genetic signals of some taxa (e.g., eukaryotes) can be weak compared to ...

Distributed acoustic sensing of microseismic sources and wave propagation in glaciated terrain

Nature Communications, 2020
In this study, Walter and colleagues deploy a 1 km long fiber optics cable on a glacier surface. Via the use of distributed acoustic sensing, the authors are capable of monitoring glacier dynamics and Alpine mass movements.

Grounding‐Zone Flow Variability of Priestley Glacier, Antarctica, in a Diurnal Tidal Regime

Geophysical Research Letters, 2021
Tidal modulation of ice streams and their adjacent ice shelves is a real‐world experiment to understand ice‐dynamic processes. We observe the dynamics of Priestley Glacier, Antarctica, using Terrestrial Radar Interferometry (TRI) and GNSS.

Early deglaciation history of the southeastern Baffin Island shelf (Eastern Canadian Arctic Archipelago)

Journal of Quaternary Science, EarlyView.
ABSTRACT During the last glacial period, the Laurentide Ice Sheet (LIS) was the largest terrestrial ice sheet on Earth. Its evolution since the Last Glacial Maximum profoundly influenced Earth's geodynamics and surface processes. Investigating the past dynamics of the LIS provides critical insights into how contemporary ice sheets may respond to ...

Modeling of ocean‐induced ice melt rates of five west Greenland glaciers over the past two decades

Geophysical Research Letters, 2016
High‐resolution, three‐dimensional simulations from the Massachusetts Institute of Technology general circulation model ocean model are used to calculate the subaqueous melt rate of the calving faces of Umiamako, Rinks, Kangerdlugssup, Store, and ...

Evaluating Greenland glacial isostatic adjustment corrections using GRACE, altimetry and surface mass balance data

Environmental Research Letters, 2014
Glacial isostatic adjustment (GIA) represents a source of uncertainty for ice sheet mass balance estimates from the Gravity Recovery and Climate Experiment (GRACE) time-variable gravity measurements.

Deglaciation of the Burren glacio‐karst, western Ireland, during Termination 1: Implications for North Atlantic climate and karstification

Journal of Quaternary Science, EarlyView.
Abstract The Burren uplands in western Ireland form one of the most extensive and best‐preserved examples of glacio‐karst in Europe. Subsumed by the Irish ice sheet during the Late Pleistocene, granite erratic boulders and in situ silica veins in the limestone bedrock provide a rare opportunity to reconstruct the timing and rate of deglaciation ...

Women in Glaciology, an Historical Perspective

, 2010
Women\u27s history in glaciology extends as far back in time as the discipline itself, although their contributions to the scientific discourse have for all of that history been constrained by the sociopolitical contexts of the times.
