We investigate the geometry and ventilation of the water masses within bathyal depths (~1500 - ~2500 m) of the Southeast Pacific (SEP), inferring the lower depth limit variations of the Antarctic Intermediate Water (AAIW) since ~22 kyr cal. BP. We use three cores collected at the upper limit of the...
