Geophysical evidence for the extent of crustal types and the type of margin along a profile in the northeastern Baffin Bay [PDF]

Journal of Geophysical Research: Solid Earth, 2015
AbstractInvestigating the crust of northern Baffin Bay provides valuable indications for the still debated evolution of this area. The crust of the southern Melville Bay is examined based on wide‐angle seismic and gravity data. The resulting P wave velocity, density, and geological models give insights into the crustal structure. A stretched and rifted

The Northern Margin of Greenland from Baffin Bay to the Greenland Sea

1981
Greenland, with a surface area of about 2,186,000 km2, is the largest island in the world. It is composed of a central depression, now totally filled by the Inland Ice, and a mountainous coastal “ice-free” zone forming 20% of the total area.

Characteristics of the West Greenland Margin in the Southern Baffin Bay

Proceedings (EAGE), 2012
For reliable hydrocarbon assessment of the West Greenland margin information about the structural inventory including the location of the continent ocean boundary is of special importance. There is still no consensus about the nature of the underlying crust in central Baffin Bay. A new multichannel seismic traverse extending from the outer shelf of the

Arctic phytoplankton spring bloom diversity across the marginal ice zone in Baffin Bay

2022
Abstract Phytoplankton under-ice blooms have been recently recognized as an important Arctic phenomenon for global primary production and biogeochemical cycling. Drastic sea-ice decline in both extension and thickness enables the development of early blooms, sometimes hundreds of kilometers beneath the pack ice ...

A new oil-window indicator? The magnetic assemblage of claystones from the Baffin Bay volcanic margin (Greenland)

AAPG Bulletin, 2012
Identifying independent parameters to bracket the oil window in sedimentary basins is of first importance for petroleum exploration. We investigate the magnetic assemblage of Cretaceous claystones collected from the western volcanic margin of Greenland.

The Continental Margins of Eastern Canada and Baffin Bay

1974
Canada’s eastern continental margin extends over some 40 degrees of latitude from Georges Bank to Ellesmere Island. This account describes only a few of the features of this extensive continental margin, illustrative of the variations in geologic style. Full accounts have been written recently by a number of investigators (e.g., Barrett and C. E. Keen,

NE Canada Rifted Margin Composite Tectono-Sedimentary Element, Baffin Bay, Davis Strait and Labrador Sea

Geological Society, London, Memoirs, 2023
The NE Canada Rifted Margin (NCRM) Composite Tectono-Sedimentary Element (CTSE) developed during a long and complex history that produced two tectono-sedimentary elements (TSEs): (1) the pre-rift TSE of pre-Cretaceous age; and (2) the synrift TSE of Early Cretaceous–Paleocene age.

Linking marine core lithofacies and mineral and grain-size compositions on the Baffin Island margin: changes in provenance and transport

Journal of Sedimentary Research, 2020
ABSTRACT We evaluate the linkages between lithofacies and mineral composition of late Quaternary sediments along the Baffin Slope for cores 2013029 64, 74, and 77. Four major lithofacies were identified: diamicton (L1), laminated red-brown mud (L2), tan carbonate mud (L3), and brown bioturbated mud (L4).

Along-slope variations in sediment lithofacies and depositional processes since the Last Glacial Maximum on the northeast Baffin margin, Canada

Marine Geology, 2018
Abstract Twelve piston cores were used to characterize late Quaternary lithofacies, depositional processes and deglacial history along the Baffin Bay slope between Lancaster Sound and Home Bay. Core investigations show four distinct laterally correlatable lithofacies along the slope – basal and upper diamicton, laminated red brown mud, tan carbonate ...

Late glacial ice margins and deglacial chronology for southeastern Baffin Island and Hudson Strait, eastern Canadian Arctic

Canadian Journal of Earth Sciences, 1992
Radiocarbon dates from marine piston cores and from onshore raised marine stratigraphic sections in the Hudson Strait region were used to reconstruct deglacial isochrons for 9900, 9500, 8800–8500, and 8000 BP. At the culmination of the Gold Cove readvance (9900 BP), Labrador–Ungava ice flowed northeastward across Hudson Strait and outer Frobisher Bay ...
