as well as the signal transfer to surface waters in
the coastal upwelling regions (GeoB 1023-5). However, ifthe hypothesis is correct that the thermodynamic imprint is transferred by AAIW, regions
with little or no AAIW should record a different
signal. The Southern Caribbean is a region where
the AAIW is already considerably diluted by Upper North Atlantic Deep Water. Core M35003-4
