Missing annotation in the system: the instruments on the profiler quit long before the deployment end date.

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”.

10% of optical_absorption data are outside of global ranges or outliers (+/- 5 SD).

The file coordinate pressure_depth is an array of all zeros. 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.
