Eurasia-North America Chrons 1-6 plate reconstruction data: Arctic and north Atlantic basins

Identifications of magnetic reversals from Anomaly 1 (0.78 Ma) to Anomaly 6 (~20 Ma) from a wide range of shipboard and airborne magnetic data from the Arctic Basin and northern Atlantic spreading centers are embedded in a text file along with fracture zone (and transform fault) traces that were digitized from best-available bathymetric and satellite gravity data. These include all the data that were used to estimate the high-resolution Eurasia-North America plate rotation sequence described by Merkouriev and DeMets (2014). A detailed description of the file contents is found at the start of the file. The data file is in ASCII text format and was generated as part of a project called Toward an understanding of Neogene plate dynamics: Completion of a high-resolution, closure-enforced chronology of global plate motions since 20 Ma. Funding was provided through NSF award OCE14-33323 and Russian Foundation grant 05-04-64297.
