Alloa Quality Report

Screening and QC

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

During screening noisy periods were observed in several parameters, but these were left unflagged. M flags were applied to spikes and to slightly negative values in TURBXXXX, ODSDM021 and CPHLZZXX. In the TURBXXXX and CPHLZZXX channels there were also negative vlaues which where less than -1 NTU and -1 mg m-3 respectively that were flagged null. These values are available on request. Null values were assigned an N flag.

Prolonged periods with constant data were also considered anomalous and flagged, these can be identified for TEMPPR01 in a number of series including 1205004 and 1205028. Several series also exhibit anomalous TEMPPR01 data which were flagged (e.g. series 1204916, 1204941, 1204953, 1204965, 1204989, 1205028, 1205053, 1205065).

A period with anomalous DOXYSZZ01, PHXXZXX and PSALZZXX has been identified in series 1205201 (from 18 August 2009 12:00 hours to 21 August 2009 11:00 hours). After some investigation, it was decided not to assign any quality flags as it these data were found to be related with a meteorological event. Although readings are considered to be valid, the data should be used with caution.

For some series, TURBXXXX and CPHLZZXX exhibit some high values which might be related with particles adhering to the sensor. These instances have not been flagged.

Ship service visits were taken at a single point in time, where stated in the originator's 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 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
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
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 Alloa long-term monitoring buoy

Data Acquisition and Analysis

Data were obtained from a probe attached to a mooring deployed in Firth of Forth, off Alloa. The mooring was serviced and deployed by the Scottish Environment Protection Agency (SEPA) for the purpose of long-term monitoring. Up to 3 March 2011, a Hydrolabs probe was used and subsequently replaced by a YSI 6600 probe.

The raw data were downloaded directly from the instruments, occasional problems during the remote downloading of data meant that sometimes strings were overwritten, leading to one parameter being downloaded at the expense of another. So although all parameters were measured, not all were included in the originator's files. Data were downloaded in local time and following discussion with BODC they were then corrected to GMT before being submitted.

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.

SEPA South Alloa Fixed Station Mooring

Location Name Alloa
Nominal Latitude (+ve N) 56.10
Nominal Longitude (+ve E) -3.81
Water depth 5 m
Period of data collection Initiated in 1988

The buoy is located in the upper Forth estuary, near Alloa, and provides measurements of dissolved oxygen, salinity, temperature, pH, chlorophyll and turbidity. Its maintenance is done on a monthly basis using one of SEPA's support vessels and is done in such a way as to prevent loss of information, for more recent records, this includes a change in the probe that is installed in the buoy, thus making readings continuous through time.

Up until July 2010, the sampling interval was set to collect a measurement every 15 minutes. From then until July 2014, a measurement was collected every 30 minutes. From this point, a sample was collected every 15 minutes. This buoy has also seen a change in the measurement probes, up to 3 March 2011, the measurements were collected with a Hydrolab Ms5, which was subsequently replaced by a YSI 6600 probe.

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