These fluctuations do not appear to have affected the temperature data and therefore no flags have been added.

Orkney Passage Moorings: 2015 - 2017 Quality Control Flags

Flags were added to each parameter by the data originator. These flags correspond to WOCE quality control flags.

The flags were converted to BODC flags during BODC processing procedures and the conversion is displayed in the table below:

Originator Flag Originator Flag Description BODC Flag BODC Flag Description Comments
0 no quality control done - - No flag added
1 good data - - No flag added
2 probably good data - - No flag added
3 probably bad data L improbable data value - originator's quality control -
4 bad data L improbable data value - originator's quality control -
5 changed - - No flag added as none were included in the originator's files

Originator's improbable data flags (L flags) were applied to the following SBE37 series reference numbers: 1880975, 1881106, 1881167, 1881211, 1881223, 1881235, 1881247, 1881259, 1881260, 1881303, 1881339 and 1881376.

Originator's improbable data flags (L flags) were applied to the following RCM11 series reference numbers: 1893710 and 1893734.

Sea-Bird SBE 37-SMP MicroCAT

The SBE 37-SMP MicroCAT is a high accuracy conductivity and temperature recorder (pressure optional) with Serial interface, internal battery, non-volatile FLASH Memory and integral Pump. The Integral Pump runs for 1 second each time the MicroCAT samples, improving the conductivity response and giving improved anti-foul protection.

Designed for moorings and other long-duration, fixed-site deployments, MicroCATs have non-corroding titanium housings rated for operation to 7000 meters or pressure sensor full scale-range. Communication with the MicroCAT is over an internal, 3-wire, RS-232C link. The MicroCAT's aged and pressure-protected thermistor has a long history of exceptional accuracy and stability (typical drift is less than 0.002°C per year). Electrical isolation of the conductivity electronics eliminates any possibility of ground-loop noise.

BODC Data Processing

Data Processing

The data arrived at BODC as individual .mat files containing data collected on moorings OP1, OP2, OP3, OP4, OP5, OP6, OP7, CI1 and CI2. They were submitted as part of an accession which includes data from several mooring instruments e.g. Aquadopp, RCM8, RCM11, RBR, SBE37 and SBE39.

Reformatting

Parameters in the originator's files were reformatted into an internal file format using BODC standard procedures.

The following table lists all the parameters included in the internal format files, showing how the originator's variables as named in the matlab files were mapped to appropriate BODC parameter codes.

    2017 - 2019 only    
press dbar PREXPR01 dbar Used for both SBE39 and SBE37 data where a pressure sensor was available on the intrument

No derived parameters were calculated by BODC. Please note that not all parameters are present in all files.

Screening

Quality control flags were automatically added to data outside the expected parameter specific range during the reformatting process. All parameters were then visualised and screened using in house software, and any improbable or missing data point was assigned a quality control flag.

Originator's Data processing

Sampling strategy

Sampling was carried out as part of the BAS LTMS (British Antarctic Survey Long Term Monitoring and Survey) until 2016. From 2016 onwards the moorings are split between 'The Ocean Regulation of Climate by Heat and Carbon Sequestration and Transports (ORCHESTRA)' project and 'Dynamics of the Orkney Passage Outflow (DynOPO)' project.

The projects involve the deployment of moorings CI1, CI2, OP1, OP2, OP3, OP4, OP5, OP6 and OP7 in the Southern Ocean, situated north of Coronation Island and the Orkney Passage in the Weddell and Scotia Sea.

Moorings CI1 and CI2 were deployed from 2005 to 2007 and moorings OP1, OP2, OP3, OP4, OP5 and OP6 have been continuously maintained since 2007 with the addition of OP7 in 2015.

SBE 37 and SBE39 instruments were deployed on the moorings. Data have been collected at variable intervals: 5 minutes interval on the Coronation Island moorings, 7.5 minute interval on the instruments deployed on OP2 and OP3 in 2007 and 15 minute intervals since then. Gaps in the series may be caused by either instruments not being recovered, or data not being collected due to instrument malfunction.

Data processing

Little information is known with regards to the exact details of the calibrations carried out on the mooring data. Data processing, visualisation and calibration were carried out through the use of scripts for Matlab version R2014b produced and ran by the originator.

An offset has been applied some of the channels. The values for each deployment/instrument/channel combination are shown in the table below:

Several instruments deployed in the 2013/15 period show evidence of knock-down but the data colleaction seems to be unnafected. According to the originator some of the moorings were deployed with insufficient buyoancy which caused the knockdowns. These instances are especially visible on moorings OP1 and OP2, Series Reference number 1840205, 1840229, 1840254, 1840266 and 1840278

Several instruments deployed in the 2015/17 period did not have a pressure sensor and used inferred pressure calculated from the closest neigbhouring pressure sensor. This includes five SBE39 instruments (s/n 4413, 4716, 4713, 4418 and 4409) and one SBE37 instrument (s/n 8267).

Several instruments deployed in the 2017/19 period did not have a pressure sensor, therefore no pressure channel was transferred with the data and only a nominal depth is used in the metadata. This includes all SBE39 instruments (s/n 4413, 4409, 0083, 4713, 4418 and 4716) and one SBE37 instrument (s/n 8267).
