Maintenance and Update Frequency: notPlanned Statement: Sediment was recovered using a Kullenberg core, aboard the research vessel Marion DuFresne. The method used to produce diatom slides from sediment samples is described in the 'methodology' document uploaded with this record. Statement: Sediment samples for analysis were taken at 10cm intervals from the sediment surface down to a depth of 1030cm. The core age model must be considered provisional since additional independent tie-points to age have not been made for the cores, such as AMS 14C dating of the foraminifera in the surface sediments, nor was the oxygen isotopic data of the cores at high resolution. There is room for error in the positioning of the last abundant appearance datum of H. karstenii at the base of the core, as the core ends just where the signal begins to increase. Parameters: Core depth (cm), delta 18O (using N.pachyderma), tie-points in SPECMAP age scale (ka), correspoding SPECMAP age scale (ka), linear sedimentation rate (cm/ka), Analyseries extrapolated age scale (ka) at 10cm interval, core sample dry weights (gm), field of views counted, diatom subtotal count, number of diatom frustules (x1000000)/gm dry weight, diatom transfer function factor 1 loading, diatom transfer function factor 2 loading, diatom transfer function factor 3 loading, diatom transfer function factor 4 loading, diatom transfer function factor 5 loading, diatom transfer function factor 6 loading.
