Magnetic Anomaly image data, Reykjanes Ridge, Langseth cruise MGL1309 (2013, investigators Fernando Martinez and Richard Hey)

This magnetic anomaly data was derived from magnetic total field data acquired with a Geometrics G-882 Cesium magnetometer towed 200 m behind the ship. The International Geomagnetic Reference Field was removed from the total field values to produce the magnetic anomaly which was gridded in 0.5 minute cells using GMT-5 software (Wessel et al., 2013). The magnetic survey was conducted at the southern end of the Reykjanes Ridge, a segment of the Mid-Atlantic Ridge, in 2013 during Langseth cruise MGL1309 (investigators Fernando Martinez and Richard Hey). The data file is in PDF format. It is cited in Martinez and Hey, 2017, and was generated as part of the project called Test Between Thermal and Tectonic Hypotheses for North Atlantic Seafloor Spreading Geometry Reorganization. Funding was provided by NSF award OCE11-54071.
