RC2901 Navigation:Primary

Processed ship-based Navigation Data from the Southern Chile Trench acquired during the Robert D. Conrad expedition RC2901 (1988)

This data set was acquired with a ship-based Navigation system during Robert D. Conrad expedition RC2901 conducted in 1988 (Chief Scientist: Dr. Steve Cande). These data files are of Text File (ASCII) format and include Navigation data and were processed after data collection. Data were acquired as part of the project(s): Paleogene Geomagnetic Polarity Timescale, and funding was provided by NSF grant(s): OCE86-14508 and OCE85-11388.
