MGL1309 Backscatter:Acoustic
Acoustic Backscatter data, Reykjanes Ridge, Langseth cruise MGL1309 (2013, investigators Fernando Martinez and Richard Hey)
This processed acoustic backscatter data was extracted from the R/V Langseth Kongsberg EM122 multibeam files and processed using MB-System software (Caress and Chayes, 2008) including corrections for angular equalization. The data was gridded using GMT-5 software (Wessel et al., 2013) in 0.0005 x 0.00025 degree cells in longitude and latitude. The data file is in netCDF:GMT grid 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.
