Data Release to Multi-proxy record of ocean-climate variability during the last 2 millennia on the Mackenzie Shelf, Beaufort Sea (2013)
April 29, 2023
A 2,000 year-long oceanographic history of a Canadian Beaufort Sea continental shelf site (60-meters water depth) near the Mackenzie River outlet is reconstructed from various proxies: ostracode faunal assemblages, shell stable isotope ratios (δ18O, δ13C) and sediment biogenic silica. These proxies are extracted from three sediment cores that made a composite section, HLY1302 JPC32, GGC30, MC29. The composite core has chronology derived from radiocarbon dating and 137Cs and 210Pb correlations.

Multi-proxy record of ocean-climate variability during the last 2 millennia on the Mackenzie Shelf, Beaufort Sea
A 2,000 year-long oceanographic history, in sub-centennial resolution, from a Canadian Beaufort Sea continental shelf site (60meters water depth) near the Mackenzie River outlet is reconstructed from ostracode and foraminifera faunal assemblages, shell stable isotopes (delta 18O, delta 13C) and sediment biogenic silica. The chronology of three sediment cores making up the composite section was es
