Scientific history, sampling approach, and physical characterization of the Camp Century subglacial material, a rare archive from beneath the Greenland Ice Sheet [PDF]

The Cryosphere
Basal materials in ice cores hold information about paleoclimate conditions, glacial processes, and the timing of past ice-free intervals, all of which aid understanding of ice sheet stability and its contribution to sea level rise in a warming climate ...

New age‐estimate data and implications for marine isotope stage 7 and 5e sea levels in Fenland, eastern England

Journal of Quaternary Science, Volume 41, Issue 1, Page 36-60, January 2026.
ABSTRACT Only one last interglacial relative sea‐level indicator point (SLIP) has been recognised for Fenland, eastern England, and the nearest penultimate interglacial SLIP is located on the north Norfolk coast. Such limited information restricts the regional input to, and hence the relevance of, global reconstructions of late Middle and Late ...

Comments on ‘Late Middle Pleistocene Wolstonian Stage (MIS 6) glaciation in lowland Britain and its North Sea regional equivalents – a review’

Boreas, Volume 55, Issue 1, Page 258-271, January 2026.
Divergent views debated over the past 20 years on the Wolstonian depositional record of Fenland and the Peterborough area have centred on whether there is evidence of a single (middle or late) glaciation or of both a middle and a late glaciation. A recent review promoted a single late Wolstonian glaciation, despite there being incontrovertible evidence

Automated X‐ray computed tomography‐based analysis of clast fabric in drill‐cores of glacial diamicts using deep learning models

Boreas, Volume 55, Issue 1, Page 57-72, January 2026.
Clast‐fabric analysis is a widely used method for investigating depositional and deformation processes in glacial sediments. However, traditional field‐based approaches lack standardization, are time consuming and introduce sampling bias. This study aimed to develop a novel approach to automate clast‐fabric analysis using machine learning‐based image ...

The diamictons of Río Blanco basin, Cordon del Plata, Mendoza

, 2020
Both the sediments and the geomorphic setting of the diamictons along Rio Blanco on the piedmont east of the Cordon del Plata indicate that they could not have been deposited there by a glacier tongue, as I and several earlier observers have suggesred Rather, they must have been deposits of long-runout debris flows, as argued by Polanski.

Neoglacial readvance of the East Antarctic Ice Sheet to the northern Drygalski Basin (western Ross Sea)

Geoscience Letters
Our study investigates late Holocene ice-sheet activity in the northern Drygalski Basin (western Ross Sea) using a multi-proxy approach, including sediment properties, geochemical indicators, and diatom assemblages, combined with AMS 14C ages of a ...

Famennian glaciation in the eastern side of Parnaíba Basin, Brazil: evidence of advance and retreat of glacier in Cabeças Formation

Brazilian Journal of Geology
Glaciotectonic features studied in the siliciclastic deposits of Cabeças Formation, Upper Devonian, represent the first evidence of Famennian glaciation in Southeastern Parnaíba Basin, Brazil. Outcrop-based stratigraphic and facies analyses combined with
