Contemporary (2001) and ‘Little Ice Age’ glacier extents in the Buordakh Massif, Cherskiy Range, north east Siberia [PDF]

, 2010
The Buordakh Massif of the Cherskiy Range of sub-arctic north east Siberia, Russia has a cold continental climate and supports over 80 glaciers. Despite previous research in the region, a georeferenced map of the glaciers has only recently been completed

Aldegondabreen glacier change since 1910 from structure-from-motion photogrammetry of archived terrestrial and aerial photographs: utility of a historic archive to obtain century-scale Svalbard glacier mass losses

Journal of Glaciology, 2021
Photogrammetric reconstructions of the Aldegondabreen glacier on Svalbard from 17 archival terrestrial oblique photographs taken in 1910 and 1911 reveal a past volume of 1373.7 ± 78.2 · 106 m3; almost five times greater than its volume in 2016 ...

Radiofrequency ice dielectric measurements at Summit Station, Greenland

Journal of Glaciology, 2023
We recently reported on the radio-frequency attenuation length of cold polar ice at Summit Station, Greenland, based on bi-static radar measurements of radio-frequency bedrock echo strengths taken during the summer of 2021.

"Two tribes": Handaxe shape variation shows distinct regional cultural groups in southeastern Britain between 424 000 and 374 000 BP

Journal of Quaternary Science, EarlyView.
ABSTRACT This paper examines regional and chronological variations in Acheulean handaxe morphology during Marine Isotope Stage 11 (c. 425–365 ka BP) in Britain. Using a data set of 737 handaxes from 13 securely dated sites in East Anglia and the Thames Valley, we apply three‐dimensional geometric morphometric analysis to examine morphological ...

Vulnerability of the North Water ecosystem to climate change

Nature Communications, 2021
The North Water polynya is a unique but vulnerable ecosystem, home to Indigenous people and Arctic keystone species. New palaeoecological records from Greenland suggest human abandonment c.

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 ...

Decoupling climate and human impacts on the nitrogen cycle during the Irish Bronze Age

Journal of Quaternary Science, EarlyView.
ABSTRACT Disentangling climate variability and human activity in past nitrogen cycling is key to understanding ecosystems. Previous studies in Ireland observed a widespread, permanent shift in terrestrial nitrogen cycling during Later Prehistory, potentially linked to intensifying land‐use.

Massive subsurface ice formed by refreezing of ice-shelf melt ponds

Nature Communications, 2016
The influence of surface ponding on the interior of ice shelves is currently unknown. Here, the authors combine surface and borehole geophysics on the Larsen C Ice Shelf, Antarctica, with remote sensing and modelling and show how pond refreezing ...

Modelling spatial patterns of near-surface air temperature over a decade of melt seasons on McCall Glacier, Alaska

Journal of Glaciology, 2020
We examine the spatial patterns of near-surface air temperature (Ta) over a melting glacier using a multi-annual dataset from McCall Glacier, Alaska. The dataset consists of a 10-year (2005–2014) meteorological record along the glacier centreline up to ...
