Oceanography, Vol. 24(3), pp. 26-41 doi: 10.5670/oceanog.2011.52 http://dx.doi.org/10.5670/oceanog.2011.52 ABSTRACT: Retreat of glacier ice from Nares Strait and other straits in the Canadian Arctic Archipelago after the end of the last Ice Age initiated an important connection between the Arctic and the North Atlantic Oceans, allowing development of modern ocean circulation in Baffin Bay and the Labrador Sea. As low-salinity, nutrient-rich Arctic Water began to enter Baffin Bay, it contributed to the Baffin and Labrador currents flowing southward. This enhanced freshwater inflow must have influenced the sea ice regime and likely is responsible for poor calcium carbonate preservation that characterizes the Baffin Island margin today. Sedimentologic and paleoceanographic data from radiocarbon-dated core HLY03-05GC, Hall Basin, northern Nares Strait, document the timing and paleoenvironments surrounding the retreat of waning ice sheets from Nares Strait and opening of this connection between the Arctic Ocean and Baffin Bay. Hall Basin was deglaciated soon before 10,300 cal BP (calibrated years before present) and records ice-distal sedimentation in a glacial bay facing the Arctic Ocean until about 9,000 cal BP. Atlantic Water was present in Hall Basin during deglaciation, suggesting that it may have promoted ice retreat. A transitional unit with high ice-rafted debris content records the opening of Nares Strait at approximately 9,000 cal BP. High productivity in Hall Basin between 9,000 and 6,000 cal BP reflects reduced sea ice cover and duration as well as throughflow of nutrient-rich Pacific Water. The later Holocene is poorly resolved in the core, but slow sedimentation rates and heavier carbon isotope values support an interpretation of increased sea ice cover and decreased productivity during the Neoglacial period. GEOGRAPHIC REGION: Nares Strait, Arctic-North Atlantic Oceans PERIOD OF RECORD: 10300 YrBP - present FUNDING SOURCES: US National Science Foundation (NSF) grant OPP 0713755. DESCRIPTION: The sedimentologic (sieve fractions), paleoceanographic (foraminifers, stable isotopes) and mineralogic (quantitative x-ray diffraction mineralogy: qXRD) data from radiocarbon-dated core HLY03-05GC, Hall Basin, northern Nares Strait are included in this dataset. Sieve data were acquired during sieving for foraminiferal sample preparation. Sieve fractions include >1mm, 1mm-106µm, 106-63µm. Stable C and O analyses were made at WHOI on C. neoteretis and N. pachyderma sinistral. QXRD data were measured at INSTAAR using X-ray diffraction. Core HLY03-05GC: 81°37.286'N, 63°15.467'W, 372cm long, 797m water depth. DATA: Table 1. Radiocarbon dates from core HLY 03-05GC, Hall Basin, northern Nares Strait.
