Reconstruction of Late Pleistocene-Holocene Deformation through Massive Data Collection at Krafla Rift (NE Iceland) Owing to Drone-Based Structure-from-Motion Photogrammetry

open access: yesApplied Sciences, 2020
In the present work, we demonstrate how drone surveys coupled with structure-from-motion (SfM) photogrammetry can help to collect huge amounts of very detailed data even in rough terrains where logistics can affect classical field surveys.

A twofold development and demise of pine stands in the Netherlands during the Allerød interstadial: two hypotheses to explain a link to climate change recorded in Greenland ice

open access: yesJournal of Quaternary Science, Volume 41, Issue 4, Page 575-586, May 2026.
ABSTRACT The second half of the Allerød interstadial in the Netherlands is characterised by pine forest. Excavated trunks of 165 pine trees at Leusden‐Den Treek in the central Netherlands (LETR16) were dated by dendrochronology and radiocarbon. Two chronologically separated pine forest phases occurred during relatively warm periods as recorded in ...

Ostracod assemblages indicating a low water level episode of Lake Peipsi at the beginning of the Holocene [PDF]

open access: yesEstonian Journal of Earth Sciences, 2009
Three sediment cores from the northern part of Lake Peipsi in eastern Estonia were analysed for their ostracod content. The investigated sediments consist of late Weichselian glaciolacustrine varved and homogeneous clay, lake marl, and gyttja. Altogether

A Hydrogeophysical Survey Utilising the sTEM and sTEMprofiler Systems: Transient Electromagnetic Data and Resistivity Models

open access: yesGeoscience Data Journal, Volume 13, Issue 2, April 2026.
We present a transient electromagnetic dataset from northwestern Denmark acquired with the novel sTEMprofiler system, mapping buried Quaternary valleys. The open dataset, including raw data and resistivity models, enables benchmarking of inversion methods and integration into geological and hydrological studies. ABSTRACT Transient electromagnetic (TEM)

Palaeoenvironmental evolution of the Baltic Sea basin during the Last Interglacial (Eemian, Mikulino stages)—a review

open access: yesBoreas, Volume 55, Issue 2, Page 282-307, April 2026.
This review presents an investigation of the evolution of the Baltic Sea basin and its connections through the Eemian Stage, based upon sequences of marine and associated deposits from the White Sea to the Southwest Baltic, via the Karelian channel. Pollen analyses, foraminiferal and ostracod analyses provide the evolution of relative sea‐level change,

Late Weichselian Potholes Near Wolverhampton, England [PDF]

open access: yesJournal of Glaciology, 1970
AbstractThree potholes and a narrow channel cut into bedrock in a side-hill position were observed beneath an Irish Sea till west of Wolverhampton, England. The potholes and the channel are believed to have been cut by subglacial or latero-glacial streams flowing beneath or immediately beside the Irish Sea ice sheet.

Late Weichselian Glaciation in the Cheshire–Shropshire Basin [PDF]

open access: yesNature, 1966
RECENTLY, Boulton and Worsley1 have interpreted the huge composite morainic suite which occurs in the Wrexham–Bar Hill area of the Shropshire–Cheshire Basin as an end-moraine marking the southern limit of the advance of an ice-sheet in the Weichselian Glaciation. This interpretation is based on a radiocarbon dating of about 28,000 years B.P.

Late Quaternary environmental changes recorded in the Danish marine molluscan faunas: Appendices 1-6 [PDF]

open access: yesGeological Survey of Denmark and Greenland Bulletin, 2004
Late Quaternary, marine deposits in Denmark have yielded 247 subfossil species of molluscs. The sites are presented, and comparisons are made between the subfossil mollusc assemblages and the 278 shell-bearing mollusc species presently living in the ...

The Late Weichselian glacial maximum in western Svalbard

open access: yesPolar Research, 1987
The glacial history of Svalbard and the Barents Sea during the Late Weichselian has been much debated during the last few years; reviews are presented by Andersen (1981), Boulton et al. (1982), ElverhBi & Solheim (1983) and Vorren & Kristoffersen (1986). In our opinion (Mangerud et al.
