The data suggest that northern s ourced waters dominated the water mass mixture during the LGM\, and that A AIW was shallower than ~850m. A d18O decrease early in Heinrich Stadial 1 (HS1) is attributed to the incorporation of deglacial meltwater into the n orthern sourced waters that continued to influence the site. Two interpret ations for the mid-to-late HS1 data will be discussed\, having opposite im plications for the vigor of the Atlantic Meridional Overturning Circulatio n (AMOC) during this interval. After HS1\, the data conform to the consens us view of AMOC variability – increased AAIW presence during the Bolling-A llerod and the Holocene\, when the AMOC was strong\, and reduced AAIW pres ence during the Younger Dryas when the AMOC was weak.
