The SBE43 dissolved oxygen sensor (DOFST-K) was incorrectly assembled and stored resulting in the membrane drying out and, in one case, tearing. Clarification with the vendor on the proper assembly and storage techniques corrected the problem, however the data collected by the DOFST-K during deployments 1-3 is erroneous and should not be used. The data for this time period is excluded to avoid having it incorrectly used and disseminated.

The surface expression for the profiler mooring broke free during a storm event on December 06, 2015 and ended up drifting north to Vancouver Island where it was recovered. No further telemetered data will be available from this mooring or profiler system for this deployment.

The surface expression for the profiler mooring broke free during a storm event in October 2016. On March 13, 2017, the subsurface sphere came to the surface and drifted north towards Vancouver Island where it was recovered from the shore. The mooring wire was severed near the base and showed signs of abrasion and other damage consistent with a ship strike. The profiler was no longer on the wire and is presumed lost at sea. No recovered profiler data is available for this deployment.

UPDATED, 2017-03-13: The subsurface float came to the surface at 06:16 UTC and drifted north towards Vancouver Island where it was recovered. The mooring wire was severed and showed signs of abrasion and other damage consistent with a ship strike. The profiler was no longer attached to the wire and is presumed lost at sea. * The buoy of the offshore Washington profiler went adrift at sometime around noon local time October 14, 2016. The subsurface beacons have not reported, so it is likely that the stretch hose between the buoy and the subsurface float parted, just as it did last year. If this is the case, the profiler is continuing to collect data, but it is no longer able to telemeter data to shore.

There is an intermittent issue with the dissolved oxygen sensor during deployment 7 (2017-04-12 through 2017-10-03). For a period during June 2017 and then again from the end of July 2017 through the end of the deployment, the CTD to which the dissolved oxygen sensor is connected records a 0 for the raw frequency. Suspect either a connector or sensor failure.

At noon on July 10, 2017, the IMM port of the profiler mooring was turned off due to the incorrect configuration of the VEL3D-K. The instrument's sample rate was set too high, resulting in unusually large data files which caused a significant increase in the IMM telemetry time and an unsustainable power draw from the profiler battery pack. To insure the profiler continues to collect data over the course of the deployment, the IMM will remain off for the duration of the Spring/Summer 2017 deployment.

Battery pack on the profiler was getting low. Sensors did not have enough power to fully operate (most noticeable in the VEL3D-K data streams), and the profiler did not have enough power to descend to the full operating depth. Stopped operating altogether on 2019-04-26 after completing 1728 profiles over the course of the deployment.

Data indicates that profiler travel up the wire is periodically blocked near 150 m, keeping it from fully ascending during a profile. Suspect fouling on the wire is impeding travel.

Review Notes

CE09OSPM-WFP01

Deployment 6 for all instruments:
Update annotation ID # 925 to indicate that the profiler was lost at sea and no recovered data are expected.
Two other issues with telemetered data need to be mentioned:
(1) the gaps in the data.
(2) the change in the sampling rate.

Are the gaps in the data as a result of a change in the sampling rate?

Deployment 9 for all instruments except FLORT (instrument was not deployed):
The data missing at the end of the deployment in recovered_host are found in the telemetered stream. Are recovered_host data incomplete?

Deployment 1 for all instruments:
