Gridded geophysical shipboard data on the South Intra-Transform segment of the St. Paul transform system (COLMEIA cruise)

Gridded shipboard multibeam bathymetry and gravity datasets acquired during the COLMEIA cruise (2013). Gridded sediment thickness derived from seismic data. Gridded crustal thickness computed from gravity. The gridded datasets cover the South intra-transform segment of the St. Paul transform fault system. Grids created with the GMT software. Grid details as follows: Bathymetry: Grid file format: nf = GMT netCDF format (32-bit float), CF-1.7 x_min: -26.6678081446 x_max: -24.4991923884 x_inc: 0.000898349526186 name: longitude n_columns: 2415 y_min: 0.416125587833 y_max: 0.917145899441 y_inc: 0.000904368793517 name: latitude n_rows: 555 Sediment thickness: Grid file format: nf = GMT netCDF format (32-bit float), CF-1.7 x_min: -26.6697086826 x_max: -24.4984586826 x_inc: 0.00225 name: longitude n_columns: 966 y_min: 0.4154644221 y_max: 0.9194644221 y_inc: 0.00225 name: latitude n_rows: 225 Free air anomaly (merged shipboard and satellite data): Grid file format: nf = GMT netCDF format (32-bit float), CF-1.7 x_min: -26.6666666667 x_max: -24.5 x_inc: 0.0166666666667 (1 min) name: longitude n_columns: 131 y_min: 0.416666666667 y_max: 0.916666666667 y_inc: 0.0166666666667 (1 min) name: latitude n_rows: 31 Gravity anomalies (Mantle Bouguer, Residual Mantle Bouguer): Grid file format: nf = GMT netCDF format (32-bit float), CF-1.7 x_min: -26.6666666667 x_max: -24.5 x_inc: 0.00333333333333 (12 sec) name: longitude n_columns: 651 y_min: 0.416666666667 y_max: 0.916666666667 y_inc: 0.00333333333333 (12 sec) name: latitude n_rows: 151 Crustal thickness derived from the gravity anomalies: Grid file format: nf = GMT netCDF format (32-bit float), CF-1.7 x_min: -26.6666666667 x_max: -24.5 x_inc: 0.00333333333333 (12 sec) name: longitude n_columns: 651 y_min: 0.416666666667 y_max: 0.916666666667 y_inc: 0.00333333333333 (12 sec) name: latitude n_rows: 151
