@article {1018, title = {Amplitude and timing of temperature and salinity variability in the subpolar North Atlantic over the past 10 k.y.}, journal = {Geology}, volume = {35}, year = {2007}, note = {id: 983}, pages = {315-318}, abstract = {Paired planktic foraminiferal δ18O and Mg/Ca data reveal trends of increasing temperatures (\~{}3 {\textdegree}C) and salinities in the subpolar North Atlantic over the course of the Holocene, which were punctuated by abrupt events. The trends likely reflect an insolation-forced northward retreat of the boundary between polar and North Atlantic subsurface waters. The superimposed variability does not appear to be periodic, but tends to recur within a broad millennial band. The records provide convincing evidence of open-ocean cooling (nearly 2 {\textdegree}C) and freshening during the 8.2 ka event, and suggest similar conditions at 9.3 ka. However, the two largest temperature oscillations in our record (\~{}2 {\textdegree}C) occurred during the past 4 k.y., suggesting a recent increase in temperature variability relative to the mid-Holocene, perhaps in response to neoglaciation, which began at about this time. }, keywords = {Bj{\"o}rn Drift, Mg/Ca, Neogloboquadrina pachyderma dextral, Ocean Drilling Program Site 984, paleotemperature}, doi = {10.1130/G23455A.1 }, author = {Came, R.
