Figure F3. A. Water temperatures recorded during three consecutive runs of APCT12 at Site 1246. These observations show a rapid change in apparent bottom water temperature while a measurement was being made during acquisition of Core 204-1246B-5H. Such a rapid change is not likely and is interpreted to indicate a sudden "recalibration" of APCT12. We were not able to identify the source of the problem. B. The effect of shifting To estimates made at Site 1246 to correct for the problem illustrated in A. APCT12 was retired after Site 1246 and replaced by APCT11.
