lODP Exp. 317 will focus on the relative importance of global sea level (eustasy) versus local tectonic and sedimentary processes in controlling continental margin depositional cyclicity. M. Urbat is invited to sail as a shipboard paleomagnetist. Principal objectives (this proposal) include the establishment of a robust time frame for the sediment drilled using Magnetostratlgraphy, both shipboard and postcruise for refinements. Further objectives, mainly of the post-cruise studies, comprise environmental magnetic methodology as to characterize (paleo-)environmental factors includeing ocean circulation which control the Canterbury Basin sedimentary record. Magnetic minerals have been shown to sensitively reflect minute depositional/geochemical changes in a variety of marine sediments. Results will improve the so far mainly seismically resolved sequence architecture and respective depositional controls. Post-cruise environmental magnetic research will focus on sequence boundaries 4 - 5 (12.4 - 11 Ma) and will be integrated with non-magnetic data (e.g. geochemistry, sedimentology) to be determined on-board by the shipboard scientific party and in post-cruise collaboration.
