Abstract
  • Thomas Washington (Ship)
  • Whole-core magnetic susceptibilities were measured on unopened sections of sediment cores collected from the eastern equatorial Pacific during the Venture expedition Leg 1 on the RN Thomas Washington. The measurements were finished within hours of retrieving the cores on deck and were processed, plotted and stratigraphic correlations between cores were made during the cruise. Furthermore, by correlating down-core variations in the magnetic susceptibility to kn9wn Pleistocene global climatic fluctuations (glacial-interglacial), estimates of the absolute chronology and sedimentation rates were made. This report is a compilation of the measurements and stratigraphic correlations made during the cruise, supported by shorebased finetuning of the chronology of the cores. The reliability of the susceptibility­chronostratigraphy is unknown, since obtaining an absolute chronology using only correlations between the cheap and fast magnetic susceptibilities and climatic timescales during a coring cruise have very little or no precedence. Therefore, further traditional chronostratigraphy (magnetostratigraphy, biostratigraphy, oxygen isotope stratigraphy, etc.) of discrete samples are warranted to verify the results. At publication time of this report (March 1990), the cores have not been opened; splitting and sampling of the cores is scheduled for May 1990.
