Processed Seismic Navigation Data (P1 format) from the Puerto Rico Trench, acquired during Langseth cruise MGL2315 (2023)

This data set was acquired with the LDEO Multi-Channel Seismic system during a seismic survey of the Puerto Rico Trench, as part of R/V Marcus G. Langseth cruise MGL2315. The data files are in U.K.O.O.A. P1/90 format and contain Seismic Navigation data that was processed after acquisition. These processed P190 navigation files should be used for processing the MCS data. The data set was collected as part of the project called Seismic Hazard, Lithosphere Hydration, and Double-Verging Structure of the Puerto Rico Subduction Zone: A Seismic Reflection and Refraction Perspective. Funding was provided by NSF awards OCE23-09734 and OCE23-09735.
