98% of sci_abs_oxygen values are NaNs - the only data available are near the surface. Lat and lon are parameters used in the data product algorithm, so I think this got messed up with the re-organization of the glider lat/lon parameters. See Redmine ticket #14486

It looks like the bin_depths changed in March 2015, after which there is a lot of noise in the upper 300m of the water column.

Approximately 50% of the seawater velocities for deployment 1 are NaNs, outside of global ranges, or outliers (+/- 5 SD)

By Lori Garzio, on 12/18/19

The .nc files for deployment 1 are missing the coordinates pressure, lat and lon.

40-70% of seawater velocities for deployments 1-3 are NaNs, outside of global ranges, or outliers (+/- 5 SD).

bin_depths are incorrect for deployments 1-3. The bin_depth ranges are about 2100 - 2700 m for all three deployments.

Missing data for deployment 1 should be annotated.

40-55% of seawater velocities for deployments 1-3 are NaNs, outside of global ranges, or outliers (+/- 5 SD).

bin_depths are incorrect for deployments 1-3. The bin_depth ranges are about 2475 - 2930 m for all three deployments.

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

By Lori Garzio, on 12/13/19

Suspect data - lots of noise and negative values

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

By Lori Garzio, on 12/13/19

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

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

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”.
