On Wednesday Aug 22 2018, an automatic protective shutdown of primary power to the OOI Cabled Array occurred during installation of a new chiller system. Power was restored on Aug 24. Due to loss of power to the Cabled Array marine infrastructure, data were not collected by the instruments.

RS03AXBS-LJ03A-11-OPTAAC303

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

By Lori Garzio, on 12/13/19

RS03AXBS-LJ03A-11-OPTAAC303

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

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

61% of beam attenuation and 84% optical_absorption values for this deployment are NaNs, fill values, outside of global ranges, or outliers (+/- 5 SD)
