New insights into one of the oldest glacial deposits in the northern Alpine foreland (Höchsten, SW Germany)

open access: yesBoreas, EarlyView.
Diamictic deposits within a presumed Early Pleistocene overdeepened basin are investigated with a combined sedimentological‐geotechnical approach including analysis via μCT scans. Sedimentary facies, geotechnical properties, and microstructures reflect a transition from glacier‐proximal deposition towards direct ice contact and subglacial deformation ...

Impacts of Hydrostatic Pressure on Distributed Temperature-Sensing Optical Fibers for Extreme Ocean and Ice Environments

open access: yesPhotonics
Optical fiber is increasingly used for both communication and distributed sensing of temperature and strain in environmental studies. In this work, we demonstrate the viability of unreinforced fiber tethers (bare fiber) for Raman-based distributed ...

Responses of shallow subarctic ponds to a warming climate in the Anthropocene: a palaeolimnological perspective from the Hudson Bay Lowlands, Canada

open access: yesBoreas, EarlyView.
We show that the biological assemblage of two lakes in the Hudson Bay Lowlands experienced shifts in their biological assemblages in a very similar period as inferred hydrological change; yet, we also show that both ponds also had a clear anthropogenic warming signal as demonstrated by similar results in a chironomid‐based palaeo‐temperature ...

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.

Volcanically induced glacier collapses in southern Jan Mayen (Sør‐Jan), Norway

open access: yesBoreas, EarlyView.
A formerly unknown glacier totally covered with tephra was found in an area of Jan Mayen where no Holocene glaciation was known. This glacier and three others in the same area melted abruptly creating jökulhlaups due to volcanic activity impacting the glacier catchments at different times in the Holocene.

Can shrubs help to reconstruct historical glacier retreats?

open access: yesEnvironmental Research Letters, 2012
In the 21st century, most of the world’s glaciers are expected to retreat due to further global warming. The range of this predicted retreat varies widely as a result of uncertainties in climate and glacier models.

Increased aeolian activity linked to Neoglacial cooling and glacier advance in southern Greenland

open access: yesBoreas, EarlyView.
Intense aeolian activity observed in the Igaliku Kujalleq records in S Greenland is not related to Norse activities. Instead, we suggest that changes in the North Atlantic atmospheric circulation pattern combined with Neoglacial glacier advances led to increased katabatic wind activity and triggered increased aeolian activity from large outwash plains.

AMIGOS-3 multi-sensor stations and the climate, ice and ocean conditions at Thwaites Eastern Ice Shelf during 2020–22

open access: yesJournal of Glaciology
The Automated Meteorology—Ice—Geophysics Observation System 3 (AMIGOS-3) is a multi-sensor on-ice ocean mooring and weather, camera and precision GPS measurement station, controlled by a Python script.
