Input data, results, and analysis datasets for 3D seismic tomography and lithospheric analysis offshore the northern Lesser Antilles - Klein et al. (2026), JGR Solid Earth

Datasets (Inputs, Outputs and additional analysis results) associated with Klein et al. (2026), 'Lithospheric inheritance and structural controls of the Atlantic lithosphere in the Northern Lesser Antilles', submitted to Journal of Geophysical Research: Solid Earth. This deposit includes: the final 3D P-wave velocity model; raw and noisy travel-time picks for both layer stripping inversion steps; MCS-picked seafloor and basement horizons used for RMS roughness analysis; OBS positions, ship navigation, and digital elevation model as used in the tomographic inversion (rotated and reprojected); initial PmP reflector geometries; initial 1D Vp starting models; and TOMO3D scripts for Monte Carlo inversion runs. Raw seismic data (OBS records and MCS profiles) are subject to coastal state approval under international maritime law (Antigua and Barbuda) and are not included in this deposit.
