Waiting on PI. This collaborative cruise aboard the RVIB N.B. Palmer collected seismic reflection, 3.5 kHz, gravity, and magnetics data as well as multibeam bathymetric and sidescan sonar data in the Terror Rift region of the Ross Sea, Antarctica. The purpose to map neotectonic faults and volcanic bodies reaching the seafloor, in order to improve the understanding of the structural history of the Terror Rift and Victoria Land Basin. Over 2500 km of multi- and single-channel seismic profiles were collected in the western Ross Sea.
