Definition of Rank

  • Rank 1 is a one-dimensional parameter
  • Rank 2 is a two-dimensional parameter
  • Rank 0 is a one-dimensional parameter describing the second dimension of a two-dimensional parameter (e.g. bin depths for moored ADCP data)

Screening and QC

The data have had QC applied by SEPA with suspect data being removed. Data then went through BODC QC procedures.

During BODC screening noisy periods were observed in several parameters but these periods were generally left unflagged. Spikes in all channels were looked at in closer detail and M flags were applied if necessary. Null values were assigned an N flag.

Several series (1217890, 1217969, 1217970, 1217994 and 1218008) exhibit noisy CPHLZZXX and TURBXXXX data. These data have not been flagged as they were considered real events, however they should be used with caution. TURBXXXX and CPHLZZXX also exhibit occasional high values in some series which may be related to particles adhering to the sensor. For series 1217945, 1218740 and 1218764, CPHLZZXX appears to have quality issues and suspect flags were applied to any values of 500 mg m-3, all other points were left unflagged. Users are advised to use caution when dealing with these data. The same caution is advised for DOXYZZ01 and OXYZZ01 data for series 1218703, as the channels are extremely noisy.

Duplicate cycles were found in series 1218531 and 1218579 during BODC processing. All parameters in the duplicate cycle in series 1218531 were null and so the duplicate cycle was deleted. In series 1218579, all parameters were null in the duplicate cycles apart from TEMPPR01. The duplicate cycles were removed and TEMPPR01 was then interpoltaed and flagged T during BODC QC for these cycles.

Ship service visits were taken at a single point in time, where stated in the originator's data.

During BODC processing, any null periods in the data were removed where a parameter was null for the duration of a cruise-to-cruise event. Null periods were removed as follows:

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 and South Alloa.

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 depth of the sensors at each site is available upon request for the 2016 data onwards.

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

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
Turb NTU TURBXXXX NTU  
Chl µg/l CPHLZZXX mg/m3  
Depth m - - Depth is included in the 2016 data onwards. The channel is not transferred but is available on request.

 

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.

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.

More information may be found at the SEPA monitoring buoy network page for Gunnet Ledge.
