Core sites and down-column water chemistry profiles. Maps of the southwest Iberian margin (a) showing modern ocean current trajectories of Mediterranean outflow water (MOW [shown in orange]), which flows around 500–2000 m depth, and locations of SHAK06-5K (open circle) and MD95-2042, U1386, and U1389 (black dots). Orange arrows show approximate sediment transfer courses out of the Gulf of Cadiz9,61,65,84. Bathymetric contours are shown at 50 m intervals as adapted from Ocean Data View (Schlitzer, R. Ocean Data View, odv.awi.de, 2018). b, Contemporary profile around 37.5 °N for salinity, which correlates with seawater density50. Also shown are estimates of the modern (solid hatches) and deglacial (stipled hashes) nepheloid layer mixing (peak) depths16,17,50,84, which are reflected by particulate-matter concentration maxima. Deglacial nepheloid layer depths are derived from numeric simulations50,84 considered together with complementary grain-size, isotopic and foraminiferal data regarding glacial MOW dynamics3,8,50.
