According to Roesler and Barnard (Optical proxy for phytoplankton biomass in the absence of photophysiology: Rethinking the absorption line height, Methods in Oceanography, 2013), “absorption meters are highly prone to biofouling, particularly biofilms which not only attenuate the collimated beam but also impact the scattering properties of the optical surfaces and tubes. In productive coastal waters biofouling can have significant impacts (i.e. 10% of the signal) within one to two weeks”.

There is no pressure variable in the .nc files. This should be a coordinate.

Per vendor feedback, the first 1-2 min of each AC-S instrument sampling period should be considered suspect. Signal drift can occur as the instrument warms up, flushes with seawater, and the filter wheel spins up.

Data telemetry disabled due to chronic issues with power generation and management. The instruments could be revived to send data via telemetry when sufficient power is available. Note: Instruments may continue to collect data on internal battery power.

Deployment 11: UPDATED 2020-04-27: As of 2020-03-12 telemetered data for most instruments are being sent home via Iridium. A gap in telemetered data is expected between 2020-01-08 and 2020-03-12 and will not be backfilled but these data will be available upon recovery.* As of 2020-01-08 both fleet broadband telemetry pathways have failed and data can no longer be telemetered to shore from this mooring. Instruments will continue to log data which will be available upon recovery.
