    • Data Release to Multi-proxy record of ocean-climate variability during the last 2 millennia on the Mackenzie Shelf, Beaufort Sea (2013)

    Metadata Updated: July 6, 2024

    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.
