Séquence sédimentaire du secteur aval de la rivière Coppermine, Territoires du Nord-Ouest [PDF]

, 1985
L'étude des sédiments exposés dans 31 coupes le long du cours inférieur de la rivière Coppermine, entre les monts September et Coppermine et le golfe du Couronnement, a permis de reconstituer l'évolution postglaciaire de la région.

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

Nouvelle séquence glaciaire antérieure aux Sédiments de Saint-Pierre, Sainte-Anne-de-la-Perade, Québec [PDF]

, 1991
Trois nouvelles unités, d'origine glaciaire et glaciolacustre, antérieures aux Sédiments de Saint-Pierre, sont définies sur la rive nord du Saint-Laurent, entre Sainte-Anne-de-la-Pérade et Grondines.

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 ...

Origin, evolution and dynamic context of a Neoglacial lateral-frontal moraine at Austre Lovénbreen, Svalbard [PDF]

, 2013
Moraines marking the Neoglacial limits in Svalbard are commonly ice cored. Investigating the nature of this relict ice is important because it can aid our understanding of former glacier dynamics.

Insights into glacial processes from micromorphology of silt-sized sediment [PDF]

The Cryosphere
Silt-rich meltwater plume deposits (MPDs) analyzed from marine sediment cores have elucidated relationships that are clearly connected, yet difficult to constrain, between subglacial hydrology, ice-marginal landforms, and grounding-zone retreat patterns ...

Sedimentology and geomorphology of tufa barrages on rock coast shore platforms

Sedimentology, Volume 72, Issue 7, Page 2173-2200, December 2025.
ABSTRACT Despite tufa deposits being widely distributed and increasingly recognised globally on rock coasts, their distribution in the tidal frame and geomorphology is poorly understood. The distribution, sedimentology and geomorphology of tufa barrages on supratidal rock coasts are assessed and their controls established.

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 ...
