Geochemistry, Geophysics, Geosystems – Community infrastructure and repository for marine magnetic identifications

magnetic_picks_globeMagnetic anomaly identifications form the primary data set from which the age of the oceanic lithosphere can be determined, a critical component of reconstructing the seafloor spreading history of ocean basins. This data is now available as part of an open source, community-driven online repository that contains quality-checked magnetic anomaly picks, organised by ocean basin and publication source.

The data is available for download here.

This collection of magnetic anomaly and fracture zone picks can now be explored interactively on a 3D globe on the GPlates Portal.
