COMPOSITE DEPTH SCALES
FOR THE JAPAN TRENCH, ODP LEG 186
SITES 1150 AND 11511
Jennifer C. McGuire2 and Gary D. Acton3
ABSTRACT
We present composite depth scales for the multiply cored intervals
from Sites 1150 and 1151. These new depth scales place coeval strata re-
covered in cores from different holes at a single site into a common
stratigraphic framework. At Site 1150, double coring between Holes
1150A and 1150B occurred over only a short interval between ~703 and
713 meters below seafloor (mbsf), but this is sufficient to tie the upper
portion of the stratigraphic section cored in Hole 1150A to the lower
portion cored in Hole 1150B. The upper ~100 m of the sedimentary sec-
tion at Site 1151 was double cored with the advanced piston corer and
partially cored with the rotary core barrel, resulting in the complete re-
covery of this interval. The composite depth scales were constructed us-
ing Splicer software to vertically adjust the relative depths of various
cores from one hole to the depths from another hole so as to align dis-
