Exploring the Towed-CSEM Resistivity Model of GOFAR's Transform Fault: AGU 2023

Updated: Dec 24, 2023


At AGU Fall Meeting 2023, MIT-WHOI Ph.D. student  Bailey L. Fluegel  presented a preliminary resistivity model of the GOFAR on-axis Transform Fault (GTF) derived from deep-towed CSEM receiver (Vulcan) data. In collaboration with E. Attias and D. Sherman (OCEEMlab), Bailey processed and modeled the Vulcan data for the past six months using the non-linear finite element code MARE2DEM. Unlike seafloor nodal-CSEM, modeling Vulcan data is particularly challenging due to inherent navigational uncertainties associated with deep-towed receiver arrays. Hence, the 2D electrical resistivity inversion model shown in the poster below is the first step towards rigorous high-resolution imaging of GOFAR GTF's shallow structure.

Well done, Bailey! Excellent work
