Deployment 1: profiler stopped ascending to the minimum depth in the second half of the deployment.

Unreasonably high chl-a and backscatter outliers are scattered throughout all deployments.

I submitted a helpdesk question on 11/12/2018 regarding an offset between recovered and telemetered data for all global HYPMs: "There appears to be a substantial offset between data with the same timestamps from recovered_wfp and telemetered methods for all deployments of all global WFP CTDs, and I have included information from two representative deployments of two different profilers as examples. It looks like the values recorded for the first common timestamp are exactly the same, and as the profiler moves along in time the offset between the values recorded for the same timestamp become increasingly more offset. Then, the profiler reaches the end of the profile (either at its shallowest or deepest point), resets, and the pattern begins again. This is most easily seen in the pressure data, but there is an offset for all science parameters.

The *_intersect.csv files attached contain data where recovered and telemetered timestamps intersect. For each timestamp and science parameter there are recorded values (from .nc files downloaded from the system) and the difference. For each parameter, the difference between the values at the bottom and top of the profiler's range are exactly zero, and (particularly for pressure) the differences steadily increase until they are reset at zero at the bottom/top of the profile. This pattern continues throughout the deployment. The plots attached are zoomed in to one upcast and one downcast, and highlight the offset in the data between the two methods."

Excluding data from the beginning of deployment 2 from the final statistics as the mooring was recovered and re-deployed (annotation ID 580)

The mooring was deployed 9 - 10 km from the location of the previous 4 deployments of this mooring. If this location is correct, the platform should be annotated to inform the users as to why the deployment location changed.

Deployment 5: Telemetered data are not available for this deployment because gliders were not deployed.

Deployment 7: No telemetered data are expected from any instruments on the upper WFP after 2019-09-26. These data should be avaible upon recovery.

Deployment 7: Due to a clock rollover issue, all WFPs have ceased sampling on 1/1/2020. No WFP data are being collected after this date. A resolution is being researched by the vendor.
