Located area of the 92 dated Atlantic deposit cores (see Online-only dining table 1 for accurate coordinates and water depths regarding the cores). The figures had been generated by using the water information View computer software 53 , the ETOPO bathymetry 54 (left board), and the WOA13 imply yearly salinity 55 along a mid-Atlantic north-south section (proper board).

Means

We gathered existing paleoceanographic information from Atlantic deposit cores addressing part of or even the whole 0aˆ“40 ka interval, with sedimentation costs of at least 5 cm/ky, that there exists here dating implies: radiocarbon times for middle and reasonable latitudes sediment cores, and SST or magnetized reports for sediment cores present poleward of

40A°S. Unique cores comprise added to complete spaces according to the offered geographical and liquids depth insurance, and extra radiocarbon schedules were produced to improve the prevailing era varieties of some cores (Online-only desk 1).

38A°N), reservoir ages are assumed to not have highly varied in reaction to sea blood circulation changes of the finally glacial and deglaciation. Alike holds true anyway latitudes throughout the Holocene. Hence, in middle and reasonable latitudes, and while in the Holocene at greater latitudes, the sediment cores comprise dated in the shape of calibrated radiocarbon ages. Because of this, 1427 released and 104 brand new radiocarbon schedules currently calibrated making use of the Bayesian calibration program aˆ?MatCalaˆ? 18 , therefore the IntCal13 and SHCal13 calibration shape 19,20 for North and southern area Atlantic cores, correspondingly.

We accounted for both spatial and temporary variability in 14 C tank years. To approximate spatial modifications in reservoir centuries we removed bomb-corrected reservoir centuries from the GLobal Ocean facts evaluation work for Carbon (GLODAP) data set 21 . Leia mais →
