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

description: This magnetic anomaly grid 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 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.

title: Seafloor Magnetization data, Reykjanes Ridge, Langseth cruise MGL1309 (2013, investigators Fernando Martinez and Richard Hey)

description: This three-dimensonal seafloor magnetization grid was derived from the magnetic anomaly data. To carry out the inversion for seafloor magnetization the MGL1309 magnetic anomaly grid was extended within a rectangular area using regional gridded values from Macnab et al. (1995) and ship data from Searle et al. (1998) regridded in ~1 km cells.  The multibeam bathymetry grid was extended within the same rectangular area using satellite-predicted bathymetry (Sandwell et al., 2014) to fill areas outside the multibeam coverage and regridded in ~1 km cells. The grids were mirrored to minimize edge effects and a three-dimensional Fourier inversion for seafloor magnetization (Parker, 1972) was carried out using Mirone Software (Luis, 2007) assuming a 500 m source layer with magnetization direction given by the axial geocentric dipole. Five terms in the Fourier series were used in the inversion. The resulting values were masked to the extent of the MGL1309 multibeam grid.  As the polarity transitions agreed well with two-dimensional reversal modeling of profile values no annihilator was added. 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.

title: Two-dimensional (2-D) tomographic P-wave velocity structure of the upper crust between the Mid-Atlantic Ridge and the Rio Grande Rise

description: These gridded data files present tomographic models of P-wave seismic velocity structure of the upper 2-3 km of oceanic crust between the Mid-Atlantic Ridge and the Rio Grande Rise. The models were derived from active-source data acquired during the CREST 2-D seismic experiment conducted during Langseth cruise MGL1601 in 2016 (chief scientists Bobby Reece and Gail Christeson). The models and results are described in Kardell et al. (2019). Using a 2-D constant gradient starting model of crustal velocity, iterative tomographic inversions were performed with traveltime picks of refracted arrivals on more than 2000 shot gathers. Traveltime residuals were inverted for 2-D slowness perturbations, and ray paths and traveltimes were predicted using a shortest-path algorithm. Ray tracing was performed on a 2-D grid constrained by seafloor topogrophy from multi-beam measurements and basement topography picked on migrated seismic images. The data set is in netCDF grd format, which can be used in GMT software. It was generated as part of the CREST project: Crustal Reflectivity Experiment Southern Transect. Funding was provided by NSF grants OCE15-37108 and OCE15-37169.

title: Processed high-resolution gridded multibeam bathymetry data from the New England Mud Patch

description: These multibeam bathymetry grids were collected in 2015 aboard the R/V Sharp, as part of the Office of Naval Research-sponsored Seabed Characterization Experiment (https://wwwext.arlut.utexas.edu/sbcex/). The rectangular survey region, oriented ~E-W in ~60-80 m water depths, measured ~11 km wide and 30 km long. It included 42 strike (E-W) lines spaced ~250 m apart that were used to form the data grids. Multibeam data were collected using a Reson 7125 instrument operating at 200 kHz, and processed using CARIS software. Differential GPS were used for navigation, and an Applanix POS MV inertial motion unit provided attitude control. Raw bathymetry were corrected for pitch, heave, yaw and roll. Raw bathymetry are also manually edited to remove erroneous echosounder pings, recognizable by large positive or negative anomalies from the norm. Conductivity-temperature-depth (CTD) casts were periodically collected and used to determine water depths from the swath soundings. However, this processing step posed a difficult challenge owing to the rapidly changing water masses in the survey region, which was influenced by eddies from the nearby Gulf Stream; CTD readings were insufficiently sampled both in time and space to adequately characterize the variability of the sound speed profile. Incorrect assumptions about sounds speed profile cause the cross-swath profile to either curve upwards (“smile” artifacts) or downward (“frown” artifacts). These effects can be empirically corrected within CARIS, but result in added uncertainty in the overall depth which are often expressed as mismatch between adjacent swaths. The data files are in NetCDF format (suitable for importing to GMT scripts), gridded at 1m to enhance visualization of small-scale features, which are numerous. Projection is in UTM Zone 19N. To keep file sizes manageable, the data grids are sectioned into eastern, central and western subregions.
