These data include magnetic susceptibility measured at high and low frequency on discrete sediment samples collected from the Terrebonne Basin, Gulf of America, drilled as part of the Deepwater Hydrate Coring Expedition (UT-GOM2-2) at Walker Ridge 313 Site H Holes H003 and H002.This 2023 Department of Energy funded project was focused on better understanding microbial methane generation in marine sediments and characterizing coarse-grained gas hydrate reservoirs. Sediments were recovered continuously down ...
