Title:
Raw seafloor magnetotelluric, CSEM, and seismic data acquired over the Goban Spur, during James Cook cruise JC251 (2023)
Abstract:
These raw seafloor electric and magnetic field time series data files were acquired on RRS James Cook cruise JC251 in 2023 during a joint magnetotelluric, controlled-source EM, and active source seismic experiment near the Goban Spur (https://marineemlab.ucsd.edu/Projects/Goban/) in the northeastern Atlantic Ocean. They were collected using 34 SIO Mk III OBEM seafloor magnetotelluric/electromagnetic sensors navigated with LBL acoustics. The data files are in the Scripps EM data logger binary format with Ch1 = magnetometer coil, instrument N, Ch2 = magnetometer E, Ch3 = electric field N, Ch4 = electric field E, Ch5 = seismic hydrophone. The instruments, data format, and playback software are described at https://marineemlab.ucsd.edu/instruments/. The data set was generated as part of the joint NSF GEO-NERC project called Quantifying evolution of magmatism and serpentinisation during the onset of seafloor spreading. Funding was from NSF award OCE-2026866 and from the UK Natural Environment Research Council grants NE/T007419/1 and NE/T007192/1).
