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. Id: 653 By: lgarzio |

Deployment 1: Upon recovery, the bottom of the buoy was heavily biofouled with gooseneck barnacles. The barnacle coverage likely caused imporper sea water flushing at the location of the intakes and sensor faces for the subsurface instruments. Id: 654 By: lgarzio |

salinity_corrected_nitrate is all fill values for every deployment. According to the provenance.json file, the temperature and salinity data from the collocated CTD is missing. By Lori Garzio, on 7/23/19 |

Data generally look suspect for all deployments of this instrument (the ISUS model) because of the prevalence of negative values. The dataset should be annotated if there is a known issue with this instrument to inform users if all or some data should be considered suspect. By Lori Garzio, on 7/23/19 |

GA01SUMO-SBD11-08-NUTNRB000 Deployment: 2 |
Suspect data - 19% of the values for nitrate_concentration are outside of global ranges (too high). By Lori Garzio, on 7/23/19  |

GA01SUMO-SBD11-08-NUTNRB000 Deployment: 3 |
Suspect data - 75% of the values for nitrate_concentration are outside of global ranges (mostly negative). By Lori Garzio, on 7/23/19  |
