|a 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. |
