Deployment 1: Buoy log files showed that seawater was first detected inside the buoy well on 3/26/2015. Both leak detectors showed increasing presence of water over the period of deployment. Upon recovery of the mooring, no external damage was visible and the buoy did not appear to be floating lower than normal.

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

A substantial percentage (between 25-33%) of data are outside of global ranges for every deployment. Zooming in on the x-axis in the plots shows that all of the values that are outside of global ranges are negative.

Suspect data for deployment 2 - signal gradually decreased to the end of this deployment. The values at the end of deployment 2 are significantly lower than the overlapping values at the beginning of deployment 3 - could be evidence of biofouling.

Downwelling spectral irradiance should start increasing again in Sept (after the austral winter). This increase is seen in the data from the SPKIR on the surface buoy, and is observed to a certain extent in the data from this instrument at the end of 2017 for wavelength=555nm, but not in the data from other wavelengths. This could indicate possible biofouling. Data are suspect - this should be investigated and annotated.
