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”.

beam_attenuation and optical_absorption are all fill values for deployments 2 and 3

The file coordinate pressure_depth is an array of all zeros for every deployment. The variable in the file called int_ctd_pressure has what appears to be valid pressure data. The coordinate variable pressure_depth should contain valid pressure data.

During deployments 2, and 3 there are several pressure (dbar) data points that are outliers (much deeper than the max deployment depth of 90m).

Missing data for all deployments should be annotated
