TLDR
In this paper, the authors studied sediment distribution on the Bear Island Trough Mouth Fan during the last glacial period using high resolution reflection seismics and gravity cores and found that large debris flows were generated when the Barents Sea Ice Sheet reached the shelf break.About:

TL;DR: In this paper, the maximum limits of the Eurasian ice sheets during four glaciations have been reconstructed: (1) the Late Saalian (>140 ka), (2) the Early Weichselian (100-80 ka),(3) the Middle Weichsellian (60-50 ka), and (4) the late Weichselsian (25-15 ka) based on satellite data and aerial photographs combined with geological field investigations in Russia and Siberia, and with marine seismic and sediment core data.

The last Eurasian ice sheets - a chronological database and time-slice reconstruction, DATED-1
TL;DR: In this paper, the authors present a new time-slice reconstruction of the Eurasian ice sheets (British-Irish, Svalbard-Barents-Kara Seas and Scandinavian) documenting the spatial evolution of these interconnected ice sheets every 1000 years from 25 to 10 years and at four selected time periods back to 40 years.

Debris-flow deposition: Effects of pore-fluid pressure and friction concentrated at flow margins
Jon J. Major,Richard M. Iverson +1 more
TL;DR: This paper measured porefluid pressure and total bed-normal stress at the base of several ~10 m 3 experimental debris flows to understand the process of debris-flow deposition, and found that pore-fluid pressures nearly sufficient to cause liquefaction were developed and maintained during flow mobilization and acceleration, persisted in debrisflow interiors during flow deceleration and deposition and dissipated significantly only during postdepositional sediment consolidation.

Trough mouth fans — palaeoclimate and ice-sheet monitors
Tore O. Vorren,Jan Sverre Laberg +1 more
TL;DR: In this paper, the authors identified trough mouth fans, depocentres dominated by debris flows accumulated in front of ice streams draining the former large northwest European ice sheets, as the main sites of fresh water supply to the ocean during the mid/late Pleistocene ice ages.
Journal ArticleDOI
Glacio-seismotectonics: ice sheets, crustal deformation and seismicity
TL;DR: In this paper, the authors highlight some of these recent field-based investigations and new postglacial rebound models, and examine their implications for understanding crustal deformation and seismicity during glaciation and following deglaciation.

Features of the physical oceanographic conditions of the Barents Sea
TL;DR: The Barents Sea is a shallow continental shelf sea and the physical conditions are determined by three main water masses: Coastal Water, (North) Atlantic Water, and Arctic Water as discussed by the authors.

The Role of Subaqueous Debris Flow in Generating Turbidity Currents
TL;DR: In this article, the transition from landsliding to turbidity currents was examined in the oceans as part of the sequence from landslides through debris flow to a turbidity current flow, and the mechanics of subaqueous debris flow were examined.

Apparent radiocarbon ages of recent marine shells from Norway, Spitsbergen, and Arctic Canada
Jan Mangerud,Steinar Gulliksen +1 more
TL;DR: The mean apparent radiocarbon ages of marine shells, colleted alive before the initiation of atomic bomb testing, and also before the main input of dead carbon derived from fossil fuels, are found to be 440 yr for the coast of Norway, 510 yr for Spitsbergen, and 750 yr for Ellesmere Island, Arctic Canada as discussed by the authors.

Sedimentation beneath ice shelves — the view from ice stream B
TL;DR: The Ross Sea is characterized by a regional unconformity overlain by a diamicton of probable latest Pliocene-Pleistocene age measuring several meters to tens of meters thick and tens of kilometers long.
