Resistivity models inverted from Time-Domain Controlled-Source Electromagnetic (TD-CSEM) data from the southeastern North Sea acquired during expedition AL611

Description: Surface-towed time-domain controlled-source electromagnetic (TD-CSEM) data were acquired during expedition AL611 in the southeastern North Sea to map subseafloor electrical resistivity. The survey used a 100 m horizontal electric-dipole transmitter and two inline electric-field receivers towed at ~250 m and ~500 m offsets (SWAN system, Pestoressa et al., 2023). Transients (2 s period, 50% duty) were processed for timing alignment, transient selection and filtering, DC-offset removal, stacking, and logarithmic gating. Two-dimensional resistivity models were obtained with an extended time-domain implementation of MARE2DEM (Haroon et al., 2018; Key, 2016); parameter details are documented in the metadata. The dataset includes processed TD-CSEM inputs and inversion results both as SEGY and XYZ files with embedded positions.
