Figure F39. Locations of Sites 1233-1235 on subsurface oxygen contours. Circles mark the current site locations relative to the oxygen-poor Gunther Undercurrent (GUC) and the relatively oxygen-rich Antarctic Intermediate Water (AAIW). Vertical bars on the sites indicate the likely effect of last glacial maximum sea level fall of ~130 m on the position of the sites relative to the sea surface. PCW = Pacific Central Water.
