a,b, Meridional sections showing the thermal (a) and haline (b) structure of the Atlantic. The inset in a shows the transect (red box) used to derive these sections. Hydrographic data are from World Ocean Atlas 2023 (WOA23)7,8 and were plotted using Ocean Data View44. Open circles show the locations of sediment cores from the Northwest Atlantic used in this study. Modern deep-ocean water-mass geometry is well resolved in salinity space (b).
