The composite depth scale for Holes 1077A and 1077B (Shipboard Scientific Party, 1998) contains imperfections between 115 and 155 meters composite depth (mcd). The spliced magnetic susceptibility record shows discrepancies when compared to the record of Site 1075 at 120-125 and 140-150 mcd (Ocean Drilling Program [ODP] Site 1077 scale) around marine isotope Stages 22 and 34, respectively. In addition, the offsets applied to transform the standard meters below seafloor (mbsf) depths into composite depths cause overlaps between cores of the same hole at the transitions between Cores 175-1077A-12H and 13H, 175-1077B-12H and 13H, and 175-1077B-13H and 14H. These overlaps are supported neither by visual investigation of the lithology in the core photographs (see "Site 1077 Core Descriptions and Photographs" in Wefer, Berger, Richter, et al., 1998) nor by the pollen and dinoflagellate content. For these reasons, we have reassessed the Site 1077 composite depth scale.
