Boreas, 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 ...

PhotonicsOptical 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 ...

Boreas, 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]
Geological 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
Boreas, 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?
Environmental 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
Boreas, 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.
