EW9510 Navigation:Primary

Shapefile of Processed ship-based Navigation Data acquired during the Maurice Ewing expedition EW9510 (1995)

This data set was acquired with a ship-based Navigation system during Maurice Ewing expedition EW9510 conducted in 1995 (Chief Scientist: Dr. Brian Taylor). These data files are of Shapefile format and include Navigation data and were processed after data collection. Data were acquired as part of the project(s): Propagating Rifts and Spreading Centers into Continents: The Woodlark Basin, and funding was provided by NSF grant(s): JOI-X-XX, OCE92-01691, and OCE95-03505.
