Underway geophysics¹

L.M. Kalnins² and the Expedition 330 Scientists²

Introduction

Integrated Ocean Drilling Program (IODP) Expedition 330 to the Louisville Seamount Trail had long transits of ~1500 km from Auckland, New Zealand, to the first drill site on Canopus Guyot and from the last drill site on Hadar Guyot to Auckland, New Zealand, as well as substantial transits between sites (Figs. F1, F2). In total, more than 4600 km of underway geophysical data were collected during the expedition. Bathymetric and magnetic data were collected using a 3.5 kHz echo sounder and a towed marine magnetometer, respectively, and positioned using a gyrocompass and GPS navigation system.
