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.

recovered_host data aren't expected - according to the ingest csv the raw data files are blank. This dataset should be annotated.

wavelength_a and wavelength_c are arrays of fill values for this deployment. These variables should contain the measurement wavelengths.

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.

Fuel cell impacted available instrument power, so telemetered data are not available or reliable. Recovered data are available for instruments that could record internally.

CP04OSSM D00009 buoy broke free and went adrift on 1/30/2019, 1500UTC. All instruments on the MFN ceased telemetry on 1/30/2019 and instruments on the buoy/NSIF continued to sample through 2/1/2019. No more telemetered data expected for this deployment.
