Oxygen isotopic composition of benthic foraminifers and magnesium to calcium (Mg/Ca) ratios in ostracodes were used as temperature proxies, with sea-ice duration interpreted from dinocyst assemblages. Chronology for both cores was established with radiocarbon dating Data Include: 1. 14C chronology for both cores 2. GGC19 bottom water temperature from d18O of benthic foraminifer Islandiella helenae 3. GGC19 bottom water temperature from d18O of benthic foraminifer Nonion labradoricum 4. GGC19 sea-ice duration (months/year) from dinocyst assemblages 5. P1/B3 ostracode Mg/Ca and BWT, and sea-ice duration ABSTRACT SUPPLIED BY ORIGINATOR: We reconstructed subsurface (~200-400 m) ocean temperature and sea-ice cover in the Canada Basin, western Arctic Ocean from foraminiferal d18O, ostracode Mg/Ca ratios, and dinocyst assemblages from two sediment core records covering the last 8000 years. Results show mean temperature varied from -1 to 0.5°C and -0.5 to 1.5°C at 203 and 369 m water depths, respectively. Centennial-scale warm periods in subsurface temperature records correspond to reductions in summer sea-ice cover inferred from dinocyst assemblages around 6.5 ka, 3.5 ka, 1.8 ka and during the 15th century Common Era. These changes may reflect centennial changes in the temperature and/or strength of inflowing Atlantic Layer water originating in the eastern Arctic Ocean. By comparison, the 0.5 to 0.7°C warm temperature anomaly identified in oceanographic records from the Atlantic Layer of the Canada Basin exceeded reconstructed Atlantic Layer temperatures for the last 1200 years by about 0.5°C.
