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

Missing data at the end of deployments 2 and 3 should be annotated.

CE02SHBP-LJ01D-08-OPTAAD106

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”.

optical_absorption, beam_attenutation, wavelength_a and wavelength_c are all arrays of fill values for this deployment. This should be investigated and annotated.

By Lori Garzio, on 10/3/19

CE02SHBP-LJ01D-08-OPTAAD106
Deployment: 2

Suspect data: 16% of beam_attenuation and 59% of optical_absorption values are NaNs, fill values, or outside of global ranges for this deployment.
