Location and distances to oceanic magnetic polarity block boundaries (anomalies 13ny-34ny) on a global ship track data set (South Atlantic, Indian, South Pacific, and North Pacific Oceans)
Location of magnetic polarity block boundaries and distances measured along plate tectonic flow lines in 154 ship tracks. File names are, e.g., "CAPANT-84000411_CAP_a.bmdisttrack.txt" where "CAPANT" denotes the plate boundary, "84000411" is the cruise identifier, "CAP" denotes the ridge flank, and "a" is a character distinguishing different track segments from the same cruise (additional track segments would be denoted with characters "b", "c", etc.). Each record in the data file lists a magnetic polarity block boundary (e.g., 'C13ny’), latitude and longitude of the boundary in the original track and on the track projected on a plate tectonic flow line, and distance to the boundary on the projected track. Specifically, each ship track file contains the following columns: (1) Boundary: Magnetic polarity block boundary, e.g., C13ny (young end of anomaly 13 normal block). (2) Long.: Longitude of block boundary on original track (decimal degrees). (3) Lat.: Latitude of block boundary on original track (decimal degrees). (4) Proj.long.: Longitude of block boundary on track projected on a flow line (decimal degrees). (5) Proj.lat.: Latitude of block boundary on track projected on a flow line (decimal degrees). (6) Proj.dist.: Distance to block boundary on track projected on a flow line (km). (7) Proj.dist.st.dev.: Standard deviation of distance to block boundary (km). The data files are in ASCII format and were generated as part of a project called A global survey of marine magnetic anomalies to constrain the Late Cretaceous-Eocene time scale. Funding was provided by NSF award OCE15-35937.'
