On transit cruise NBP 0207 they will take advantage of the planned track on the Pacific plate to survey across several major fracture zones, across part of the Manihiki Plateau and the Osbourne trough (to test aspects of the Mesozoic plate motion history of this region, when it may have been much farther south, adjacent to Antarctica), and along the Hikurangi trench (to study the rheology of the downgoing plate).
Also during the cruise the principal investigators will conduct a formal class in marine geophysics for 16 graduate and undergraduate students from a variety of institutions. In this way teaching activities can be integrated with the real field work of a research project.

Research Objectives:
Well-constrained Cenozoic plate reconstructions of the circum-antarctic region are critical for examining a number of problems of global geophysical importance. This group seeks to improve reconstructions involving the Antarctic and Pacific plates by surveying gravity, magnetics, and swath bathymetry on Palmer transit cruises of geological importance.
