Annotation ID 85 should be updated when the issue is resolved.

By Lori Garzio, on 3/19/19

GS01SUMO-RID16-06-DOSTAD000
Deployment: 1

Deployment 1: there is no pressure coordinate in the recovered_host data file. int_ctd_pressure is available in the file, however there are no units and this variable is not listed as a coordinate.

Deployment: 1
7/25/15, 12:00 AM 12/28/15, 12:00 AM

Excluding data from the second half of the deployment from summary data range calculation. Instrument likely biofouled (see annotation ID 778) and a high percentage of DO (umol L-L) values are outside of global ranges.

Excluding data from part of the deployment from summary data range calculation. Instrument likely biofouled (see annotation ID 779)

Deployment: 2
11/26/16, 8:45 AM 11/26/16, 11:48 PM

There is one day (2016-11-26) for which there is telemetered data but no recovered_host data. These data should be available in the recovered_host data stream.

By Lori Garzio, on 3/19/19

GS01SUMO
Deployment: 3

Annotation ID 834 needs to be updated: "Deployment 3: Recovery of the mooring was planned during the NBP 17-09 cruise (Nov - Dec 2017) but not completed due to adverse weather conditions. Recovery options are pending. Instruments that are still operational are likely reaching (or have surpassed) their deployment lifespan."

* UPDATED 2020-06-19: Deployment 3: The calibration data has been corrected so O2 data products for this deployment are now correct. * The derived O2 products (L1 Temperature Compensated and L2 Salinity Corrected Dissolved Oxygen) are suspect, due to errors during vendor calibration. Until a correction can be applied, they should not be used from 11/25/2016 onwards.

Deployment 3: *UPDATED 2020-04-28: This mooring was recovered 2018-12-09 which was a year later than originally intended. Some instruments were able to continue sampling for the extended deployment.* Recovery of the mooring was planned during the NBP 17-09 cruise (Nov - Dec 2017) but not completed due to adverse weather conditions. Recovery options are pending. Instruments that are still operational are likely reaching (or have surpassed) their deployment lifespan.

The use of UV lamps has been implemented for bio-fouling mitigation on this instrument as of the start date/time of this annotation.

Deployment 4: The NSIF experienced power failure on 2/3/19 1800UTC and power was restored on 2/11/19 1200UTC. All NSIF instruments will have this gap in their telemetered data.
