RS01SLBS-LJ01A-11-OPTAAC103

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”.

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

RS01SLBS-LJ01A-11-OPTAAC103

The .nc files for deployments 1-4 are missing the coordinates pressure, lat and lon.

By Lori Garzio, on 12/13/19

RS01SLBS-LJ01A-11-OPTAAC103

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