Description:
Transient electromagnetic data, self-potential data and plume survey data (temperature data and turbidity data) were collected at the Trans-Atlantic Geotraverse (TAG) hydrothermal mound. A double-towed system allows us to measure the transient electromagnetic data near the seafloor continuously. A deep-towed system allows us to measure the self-potential data near the seafloor continuously, meawhile, RBR sensor mounted on the steel cable measured the temperature data and turbidity data along with the self-potential survey line (RBR sensor at an altitude of approximately 80m above the seafloor). Self-potential survey and transient electromagnetic survey line are very close. All the data match to the ultra-short baseline (USBL) positioning data. By Inverting the self-potential data and transient data, delineates the geometry of the seafloor massive sulfide deposit at TAG.
