A substantial percentage of data for all deployments is outside of global ranges. It looks like the instruments biofouled shortly after each deployment (1-2 months) - the suspect data should be annotated for all deployments, and further analysis should be done using shipboard bottle data (which is outside the scope of this project).

Prior to the use of UV lamps for biofouling mitigation, this sensor would routinely biofoul after the first 6-8 weeks of a deployment (more common during a spring/summer deployment). Users should carefully examine the data to determine if biofouling has begun to dominate the signal.

The use of UV lamps has been implemented for biofouling mitigation on this instrument as of 2018-04-03T18:16:00Z.

Due to a bug in the mooring telemetry system, data during this time range was not telemetered to shore. It was recorded on the mooring and instruments and will be available in the recovered data streams.
