Sedimentary environment and glacial history of the Northwest Passage (Canadian Arctic Archipelago) reconstructed from high-resolution acoustic data
A 2420 km long profile of high-resolution sub-bottom echosounder data (PARASOUND) is interpreted for facies distribution and stratigraphy across the Canadian Arctic Archipelago including the
Seismostratigraphic and Geomorphic Evidence for the Glacial History of the Northwestern Chukchi Margin, Arctic Ocean
High‐resolution seafloor mapping provides insights into the dynamics of past ice sheets/ice shelves on high‐latitude continental margins. Geological/geophysical studies in the Arctic Ocean suggest
Sedimentary record from the Canada Basin, Arctic Ocean: implications for late to middle Pleistocene glacial history
Abstract. Sediment core ARC4-BN05 collected from the Canada Basin, Arctic Ocean, covers the late to middle Quaternary (Marine Isotope Stage – MIS – 1–15, ca. 0.5–0.6 Ma) as estimated by correlation
Glacial geomorphology of the Central Arctic Ocean: the Chukchi Borderland and the Lomonosov Ridge
The last decade of geophysical seafloor mapping in the Arctic Ocean from nuclear submarines and icebreakers reveals a wide variety of glaciogenic geomorphic features at water depths reaching 1000 m.
Seafloor evidence for ice shelf flow across the Alaska–Beaufort margin of the Arctic Ocean
New imagery of ∼14 100 km2 of seafloor along a 640 km stretch of the Alaska and Beaufort margins (ABM) in water depths from 250 to 2800 m depicts a repetitive association of glaciogenic bedforms


Quaternary history of sea ice and paleoclimate in the Amerasia basin, Arctic Ocean, as recorded in the cyclical strata of Northwind Ridge
The 19 middle-early Pleistocene to Holocene bipartite lithostratigraphic cycles observed in high-resolution piston cores from Northwind Ridge in the Amerasia Basin of the Arctic Ocean, provide a
The impact of glaciation, river-discharge and sea-level change on Late Quaternary environments in the southwestern Kara Sea
Abstract. Sedimentary records from the southwestern Kara Sea were investigated to better understand the extent of the last glaciation on the Eurasian Arctic shelf, sea-level change, and history of
Late Pleistocene–Holocene retreat of the West Antarctic Ice-Sheet system in the Ross Sea: Part 2—Sedimentologic and stratigraphic signature
Sedimentologic, geotechnical, geochemical, and accelerator mass spectrometer (AMS) radiocarbon data from two marine geologic cruises in the Ross Sea have allowed us to constrain facies relationships
Early to mid-Holocene Atlantic water influx and deglacial meltwater events, Beaufort Sea Slope, Arctic Ocean
Subglacial bedform evidence for a major palaeo‐ice stream and its retreat phases in Amundsen Gulf, Canadian Arctic Archipelago
Ascertaining the location of palaeo‐ice streams is crucial in order to produce accurate reconstructions of palaeo‐ice sheets and examine interactions with the ocean–climate system. This paper reports
