Combining morphological and molecular data to study past foraminiferal communities from a temperate coastal sediment core

open access: yesBoreas, EarlyView.
This paper presents the results of a dual approach for assessing fossil benthic foraminiferal communities using both traditional morphology‐based analyses and sedimentary ancient DNA (sedaDNA) metabarcoding. The main objectives are to test the feasibility of sedaDNA analyses to assess foraminiferal biodiversity in temperate shelf sediments (Le Croisic,

Neoglacial and historical glacier changes around Kangersuneq fjord in southern West Greenland [PDF]

open access: yesGeological Survey of Denmark and Greenland Bulletin, 2012
The Nuup Kangerlua region in southern West Greenland became eglaciated in the early Holocene and by the mid-Holocene, the margin of the Inland Ice was located east of its present position.

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

open access: yesBoreas, EarlyView.
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 ...

Quaternary glaciation history and glaciology of Jakobshavn Isbræ and the Disko Bugt region, [PDF]

open access: yesGeological Survey of Denmark and Greenland Bulletin, 2007
The Disko Bugt region in central West Greenland is characterised by permanent ice streams, of which Jakobshavn Isbræ is by far the most important. The first thorough studies on the glaciology of the region were conducted over 150 years ago by H.J.

Shoreline and deglaciation chronology in southeast Norway

open access: yesBoreas, EarlyView.
The postglacial relative sea level history is reconstructed in four areas of mid‐ and inner Oslofjorden in southeast Norway. The reconstructions are based on radiocarbon‐dated raised shoreline levels from 42 sites, mainly isolation basins, and limiting ages from four lakes above the marine limit.

Use of LiDAR to derive a new model of glacial hydro‐dynamic events shaping southern Ontario landscapes, Canada

open access: yesBoreas, EarlyView.
High‐resolution LiDAR data with field validation of inferred southern Ontario ice stream terrains indicate that steady‐state ice streaming is difficult to reconcile with our observations. Rather, these new observations show strong evidence of significant fluvial scouring across the area in which meltwater sheet flow overtopped the landscape.
