Nathaniel B. Palmer 0304 geophysics

This cruise went from Lyttelton, New Zealand to Dutch Harbor, Alaska, via Honolulu, Hawaii. The data set includes gravity, magnetics, Simrad EM120 swath bathymetry, and ODEC Bathy2000 echo sounder with 100 m subbottom penetration.

The main scientific objectives of the cruise were a) to survey outboard of part of the Kermadec trench; b) to survey a line on the Manihiki Plateau; and c) to survey the Pacific-Kula magnetic anomalies that remain on the Pacific plate south of the Aleutian Trench. Underway geophysical data are archived with NGDC. Swath bathymetry data are archived at Lamont-Doherty Geophysical Observatory.
