Última On the limits of Antarctic and marine climate records synchronization: Lag estimates during marine isotopic stages 5d and 5c ArchiMer Landais, A; Waelbroeck, Claire; Masson-delmotte, V. North Atlantic sediment records (MD95-2042), Greenland (Greenland Ice Core Project (GRIP)) and Antarctica (Byrd and Vostok) ice core climate records have been synchronized over marine isotopic stage 3 (MIS 3) (64 to 24 kyr B. P.) (Shackleton et al., 2000). The resulting common timescale suggested that MD95-2042 delta(18)O(benthic) fluctuations were synchronous with temperature changes in Antarctica (delta D-ice or delta(18)O(ice) records). In order to assess the persistency of this result we have used here the recent Greenland NorthGRIP ice core covering the last glacial inception. We transfer the Antarctic Vostok GT4 timescale to NorthGRIP delta(18)O(ice) and MD95-2042 delta(18)O(planktonic) records and precisely quantify all the relative timing...

The hydrological impact of the massive iceberg discharges during Heinrich events has been quantified for Heinrich 4 about 37 kyr ago. This event took place in a context of relatively stable orbital forcing and global ice volume. In this article, we propose to quantify the hydrological impact of the Heinrich event 1 which occurred at about 16 kyr BP. This time period is particularly interesting because orbital forcing was strong and it marks the onset of the last deglaciation. The results obtained here show that Heinrich event 1 has a larger isotopic amplitude than Heinrich event 4 when considering the cores located near the melting source. Concerning surface circulation, the northward progression of the North Atlantic Drift is affected only by Heinrich...
