For each deployment, the deployment depth in asset management is 29-30, but the pressure in the files is 39-40.

By Lori Garzio, on 6/26/19

Deployment: 8

For deployment 8, only recovered_host data from the presf_abc_dcl_tide_measurement_recovered data stream are available for download. According to the ingest csv, recovered_inst raw data files are available. These data should be ingested or the dataset should be annotated to explain why recovered_inst data aren't available.

All of the inshore surface moorings suffer from an issue called the 'top of the day problem.' A race condition exists in the CPM firmware when transferring daily log files harvested from the various sub-components in a buoy system (e.g. DCL16, CPM3, DCL35, etc) over the Iridium RUDICS connection. The primary CPM rsync's data files from the various sub-components to a central data directory. The first time a daily file is created/copied into that directory (usually shortly after midnight), a compressed copy of the file is created and that compressed file is queued up in a separate text file for transmission to shore. The transfer routine reads that text file and processes the files from that list in order from top to bottom. Once that compressed file is transferred to shore, no further updates for that file are sent to shore. Meanwhile, the CPM continues to rsync data from the different sub-components, updating the original daily log file. The net result is that data is accumulating in the daily log file for an instrument, but we may see only one record (or none) depending on when the rsync job occurred and the compressed file was created and staged for transfer to shore. This affects telemetered data only.

Correcting the iridium data telemetry issues, permitting full telemetry of data files, resulting in greater power consumption than anticipated. Result is power level of the battery pack has dropped below operational limits and subsystems can no longer power instruments. Shutting the mooring down, and placing in a low power maintenance mode. 11 instruments offline.

The buoy main battery voltage is being drawn down faster than expected. Have shutdown further power to DCL17 and to the OPTAA on DCL16. This takes the following instruments offline:
CTDBP (with attached FLORT)
Have had to power off DCL17 and DCL16 and reduce call in frequency to 12 hours. Will still (at least should) receive data from MFN. Instruments affected are:
DCL17 (Buoy)
CTDBP1 (with DOSTA) (should internally log)
PCO2W1 (should internally log)
PHSEN1 (should internally log)
NUTNR (should internally log)
VELPT2 (should internally log)

Lost communication with DCL35, on the MFN of CE06ISSM sometime after 2017/05/11 12:32:17.552. Suspect failed/corrupted SD card based on results of minicom session with DCL35 (see attached). With the exception of the VEL3D, all instruments hosted by DCL35 are autonomous. No further data should be expected from: ADCPT (recording internally), PRESF (recording internally), PC02W (recording internally), PHSEN (recording internally), VEL3D (offline)

Updated, 2020-05-24: Between 2019-10-17 and 2020-05-24, the clock on CPM3 was off by approximately 27 minutes. Communications between the buoy and the MFN were out of sync during this time period. The clock was automatically updated during routine operations on May 24, 2020 to the correct time, allowing communications and normal operations on the MFN to resume. *Communications to the seafloor sensors failed. Status of the instrumentation and data loggers is unknown. With the exception of the VEL3D and OPTAA, the sensors on the seafloor platform should continue to autonomously sample for the remainder of deployment. Until we recover and redeploy the mooring in the spring of 2020, no further telemetered data will be available from the seafloor sensors.
