Bight Fracture Zone Experiment Moored Instrument Data

Two 2-year moorings were placed in the Bight Fracture Zone (BFZ), one in the north channel and one in the south channel, between July 2015 to July 2017. Each mooring was instrumented at four depths with a pair of instruments comprised of an SBE MicroCAT and a Nobska MAVS-4 Acoustic Current Meter. The four pairs of instruments were placed at 1500, 1750, 2000 meters depth and 22 meters above the bottom of the channel (2440 meters depth in the north channel and 2115 meters depth in the south channel). The initial processing for both the MicroCAT and MAVS-4 consisted of removing data collected while out of water, replacing data outliers with NaNs, and correcting drifts in the data. In addition, the MAVS-4 data were transformed from instrument coordinates to earth coordinates and magnetic declination was correction was applied.
