Per vendor feedback, the first 1-2 min of each OPTAA instrument sampling period should be considered suspect. Signal drift can occur as the instrument warms up, flushes with seawater, and the filter wheel spins up. Users are encouraged to delete the first minute of data, at a minimum, from each measurement burst and then calculate a median average of the remaining data from the burst before working further with the OPTAA data.

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. Id: 868 By: michaesm |

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.

The buoy and mfn battery voltages have been drawn down faster than expected. Have shutdown further power to DCL16, DCL17, CPM3, and DCL37 (DCL35 failed several weeks ago). This takes the following instruments offline: DCL17

During a large storm event on 2020-01-11, the surface buoy and NSIF broke free and went adrift. As a result, telemetry from the data loggers and instrumentation on the seafloor platform has ceased. We expect the system to continue autonomous operations and hope to download data from the data loggers and instruments after the seafloor platform is recoverd in the spring of 2020.

According to Roesler and Barnard (Optical proxy for phytoplankton biomass in the absence of photophysiology: Rethinking the absorption line height, Methods in Oceanography, 2013), “absorption meters are highly prone to biofouling, particularly biofilms which not only attenuate the collimated beam but also impact the scattering properties of the optical surfaces and tubes. In productive coastal waters biofouling can have significant impacts (i.e. 10% of the signal) within one to two weeks”. By Lori Garzio, on 6/21/19 |
