During deployments 2 - 8 and 10, there are 7 - 40 pressure (dbar) data points that are outliers (much deeper than the max deployment depth of 25m).

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.

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”.

The profiler looks like it got stuck on the bottom - this should be annotated.

Deployment: 3

77%-80% of beam_attenuation and optical_absorption data for this deployment are fill values, outside of global ranges, or outliers (+/- 5 SD).
