Two of 4 beams are reporting bad measurements. The instrument was bumped on frame during deployment, and may have been compromised. Investigation and resolution may have to wait until the next deployment in Summer 2017.

A brief violent storm caused loss of power to both the North and South cable lines and the deployed infrastructure during this time. For more information please contact help@oceanobservatories.org. (Redmine # 13109)

On Wednesday Aug 22 2018, an automatic protective shutdown of primary power to the OOI Cabled Array occurred during installation of a new chiller system. Power was restored on Aug 24. Due to loss of power to the Cabled Array marine infrastructure, data were not collected by the instruments.

The .nc files are missing the pressure coordinate.

RS01SUM1-LJ01B-12-VEL3DB104

3% of seawater velocities are outside of global ranges. For eastward_turbulent_velocity there are periodic readings of >12 m/s, northward_turbulent_velocity periodic readings of 7 m/s, and upward_turbulent_velocity periodic readings of 10 m/s.

Seawater velocities look suspect for this deployment and don't follow the same pattern as the velocities for deployment 1. This should be investigated and the dataset should be annotated if there was an issue.
