The volume low-field susceptibility (k) and the Anhysteretic Remanent Magnetization (ARM) divided by k were measured using u-channel sampling technique on 2G cryogenic magnetometers at the Laboratoire des Sciences du Climat et de l'Environnement (LSCE). The Summer sea surface temperature has been determined by N. pachyderma s. percentages and planktic foraminifera assemblages (in the >150µ fraction) at LSCE. The percentage of clay and silt were measured at Laboratoire d'Océanologie et de Géosciences, Université de Lille, using a laser (0.02 -2000 µm) Malvern Mastersizer 2000.
