Abstract
Oceanic fracture zone traces are widely used in studies of seafloor morphology and plate
kinematics. Satellite altimetry missions have resulted in high-resolution gravity maps in which
all major fracture zones and other tectonic fabric can be identified, and numerous scientists have
digitized such lineaments. We have initiated a community effort to maintain low-cost
infrastructure that allows seafloor fabric lineaments to be stored, accessed and updated. A key
improvement over past efforts is our processing software (released as a GMT5 supplement) that
allows for semi-automatic corrections to previously digitized fracture zone traces given
improved gridded data sets. Here we report on our seafloor fabric processing tools, which
complement our database of seafloor fabric lineations, magnetic anomaly identifications and
plate kinematic models.
