Data Quality

Quality Control Procedures Employed:

Currently, the CBIBS data is quality controlled in the CBIBS middleware system acting on incoming data. The data gets associated with a QC flag based on threshold values set for each parameter and the buoy status. The various flags include: -1 = Unknown(NaN), 0 = Good Data, 1 = Buoy Offline, 2 = Hard Limit Test Failed, 3 = Filled Value. The data will continue to be quality controlled in this way until QARTOD (Quality Assurance of Real-Time Ocean Data) standards are implemented or if the QARTOD standards are not used for a particular parameter.

QARTOD QC Tests will be applied in a module of the CBIBS middleware, acting on incoming data at 60 minute intervals and returning resultant flag values, which are stored with the data. Parameters for the tests, which can vary by Buoy, Sensor, Measurement Parameter, and Test Type, are stored in a dynamically accessible and editable QC Test matrix. There are Primary and Secondary Flags; Primary flags represent overall Data Quality, based on QARTOD Tests; Secondary flags complement the first level by providing the justification for the quality flags, based on quality control tests or data processing history.

Data Management

Have Resources for Management of these Data Been Identified?: Yes
Approximate Percentage of Budget for these Data Devoted to Data Management: ~35%
Do these Data Comply with the Data Access Directive?: No
Is Access to the Data Limited Based on an Approved Waiver?: No
Approximate Delay Between Data Collection and Dissemination: <10 minutes
If Delay is Longer than Latency of Automated Processing, Indicate Under What Authority Data Access is Delayed:

N/A

Actual or Planned Long-Term Data Archive Location: NCEI-MD
Approximate Delay Between Data Collection and Archiving: 24 hr.
How Will the Data Be Protected from Accidental or Malicious Modification or Deletion Prior to Receipt by the Archive?:

All data operations and storage take place on secure FISMA-compliant servers.

Lineage

Lineage Statement:

The nitrate sensor sends hourly concentration values to the Watchman500 in ASCII string format. The Watchman500 sends the data via a cellular antenna to a shoreside server. Here, the data is processed (including Qa/Qc flagging) and then updated hourly on the website in real-time, where it can be downloaded (.csv file format).
