Gunnet Ledge 2013 Mooring Quality Report
Screening and Quality Control
Data have had quality control applied by the Scottish Environment Protection Agency (SEPA) with suspect data being removed. Data then went through BODC quality control procedure where suspect data are flagged but not removed.
There are a few periods through the data where power failure has occurred. These breaks in the data occur from 03 April 2013 to 12 April 2013, 26 June 2013 to 12 July 2013 and 29 October 2013 to 28 November 2013.
During screening any obvious spikes were looked at in closer detail but were generally left unflagged due to the quality control and expertise applied by SEPA.
There are instances in the data were a channel is null for a period of time due to SEPA quality control removing suspect data. These null periods have been removed from the data in the following channels:
- CPHLZZXX between 08 August 2013 and 20 September 2013
- PHXXZZXX between 14 March 2013 and 31 May 2013
- TURBXXXX from 31 May 2013 to 12 July 2013 and 08 August 2013 to 20 September 2013
CPHLZZXX was zero for a period from 04 March 2013 to 03 April 2013 and so has been flagged suspect as although CPHLZZXX was low throughout the data, it was not deemed it was likely to be zero for a considerable period. In addition to this sustained period, there are also points where CPHLZZXX drops to zero. Any instances of this have been left unflagged as SEPA have already applied quality control to data and deemed these points to be good data.

YSI 6-Series multiparameter water quality sondes
Basic information
Comprehensive multi-parameter, water quality monitoring sondes. Designed for long-term monitoring, profiling and spot sampling. The 6-series may be split into several categories: V2 Sondes, 600 Sondes, Drinking Water Sondes and System. Each category has a slightly different design purpose with V2 Sondes ideal for long-term monitoring with a greater number of parameters, whereas 600 sondes are ideal for specific applications with fewer parameters available.

SEPA Mooring Instrumentation
The SEPA long-term monitoring project has obtained hydrographic data across various moorings through the deployment of a YSI 6600 multi-parameter-sonde attached to a fixed mooring buoy at the surface of the water column.
These mooring sites include: Dunoon, Gunnet Ledge, Inner Clyde Estuary, Campbelltown, Loch Striven, Ythan, Loch Sunart, South Alloa, and Moray Firth.
The South Alloa site had two Hydrolab MS5 probes up until the 3rd of March 2011, at which point a YSI 6600 probe was used.
The Inner Clyde Estuary site also has a probe attached approximately 1 m from the sea floor in addition to the probe at the surface.
The Moray Firth site was monitored solely between July and December 2018.
The depth of the sensors at the time of measurement at each site is available upon request for the 2016 and 2017 data.
The turbidity sensors are deemed, by the manufacturer, to be used as guidance in events such as observing storm events or spotting discharges. SEPA rely on a suspended solids laboratory procedure for their turbidity reported data. The same situation occurs for chlorophyll, SEPA have a lab method they use to report it as high turbidity can interfere with the readings. This is not generally an issue in low turbidity areas.
BODC processing of SEPA's long-term monitoring buoys
Data Acquisition and Transfer
The data were sent by SEPA as yearly .csv files and following BODC's procedures the files were checked for consistency and subsequently archived.
The data were reformatted to QXF format using BODC's established procedures. During the transfer process each yearly file was split into cruise-to-cruise series events. The table below shows how the originator's parameters were mapped to BODC parameters and their units:
Originator's Parameter | Originator's Units | BODC Parameter Code | BODC Units | Comments |
---|---|---|---|---|
Temp | deg C | TEMPPR01 | °C | |
pH | pH Units | PHXXZZXX | pH Units | |
Salin | ppt | ODSDM021 | ppt | |
DO% | % Sat | OXYSZZ01 | % | For legacy data Oxygen saturation is not derived by BODC but taken from the data supplied. |
DO | mg/l | DOXYZZ01 | µmol/l | Conversion of * 31.252 was applied during transfer (Bittig et al., 2018) |
Turb | NTU | TURBXXXX | NTU | |
Chl | µg/l | CPHLZZXX | mg/m3 | |
Depth | m | PPSBPS01 | m | Depth has been transferred for 2018 onwards, and is available on request for 2016 and 2017. Depth is not available for data previous to 2016. |
Data Quality and Screening
Not all parameters occur in all series, particularly pH, turbidity and chlorophyll.
Oxygen saturation is not derived by BODC for consistency across all years and due to missing channels as mentioned in the originator's processing document.
The standard unit conversion factor of * 31.252 was applied to oxygen concentration during transfer to obtain the BODC units of µmol/l. (Bittig et al., 2018)
Post transfer analysis and crosschecks were applied according to BODC procedures. This involved the screening of data to check flags were appropriately applied whilst also applying further quality control flags where appropriate. Originator flags for "No sensor; Quality Control failure; Quality Control Spike Removed; Quality Control Spike removed, wiper incorrectly parking over sensor; Power Failure, Sensor failure" were all flagged as 'Null' as no data were available when these were applied.

SEPA originator's processing document for Gunnet Ledge long-term monitoring buoy
Data Acquisition and Analysis
Data were obtained from a YSI probe attached to a mooring deployed in the inner Firth of Forth, off Gunnet Ledge. The mooring was serviced and deployed by the Scottish Environment Protection Agency (SEPA) for the purpose of long-term monitoring. The raw data were downloaded directly from the instruments sometimes remotely. This initially caused problems as sometimes data strings would be overwritten if the function was set up incorrectly leading to one parameter being downloaded at the expense of another. Data were sent in GMT format.
Quality and Screening
Once downloaded the data went through SEPA data quality checks with suspect data removed and relevant flags attached to inform future users of the reason for any missing data. This information is available upon request.
Submission
The data were then submitted to BODC through ftp as yearly .csv files.

Period of data collection | Initiated in 1993 |
The buoy is located in the Inner Firth of Forth, at Gunnet Ledge, and provides measurements of dissolved oxygen, salinity, temperature, pH, chlorophyll and turbidity. Its maintenance is done on a monthly basis and is done in such a way as to prevent loss of information, this usually involves a change in the probe that is installed in the buoy, thus making readings continuous through time. The monitoring at this location is used in conjunction with regular collection of physical samples to assess the status of the coastal waters of the Inner Firth of Forth, as part of SEPA's obligations to the Water Framework Directive and OSPAR.
The sampling interval was initially set to collect a measurement every 30 minutes but this interval has been changed to collect samples every 15 minutes.
The water depth where the buoy is moored was retrieved from a nautical chart. The depth should be used with caution.
More information may be found at the SEPA monitoring buoy network page for Gunnet Ledge.
