Dunoon 2009-2012 Quality Report

Screening and QC

The data has had QC applied by SEPA with suspect data being removed. Data then went through BODC QC procedures; BODC's QC practice is to flag suspect data but never delete them.

The BODC QC screening of the data observed some small periods of noisy data with realistic values which were left unflagged. A few spikes have been flagged as 'M' and all data considered to be null values were flagged as 'N' automatically by the transfer and then manually crosschecked.

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

User's should be aware in June 2011 there are periods when there are extremely high turbidity values which could affect the salinity values.

During September and October 2009 there are periods when the parameters have constant values. These have been flagged suspect as 'M'.

The morning of 06/06/2009, from 05:35 to 07:45 UTC, oxygen saturation takes a while to stabilise after deployment and although some of the data points have been flagged this should still be treated with caution.

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:

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 Dunoon long-term monitoring buoy

Data Acquisition and Analysis

Data were obtained from a YSI probe attached to a mooring deployed in the Clyde Estuary just off Dunoon. 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 downloaded in local time and following discussion with BODC these data 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.

Submission

The data were then submitted to BODC through ftp as yearly .csv files.

SEPA Dunoon Fixed Station Mooring

Location Name Dunoon
Nominal Latitude (+ve N) 55.94
Nominal Longitude (+ve E) -4.92
Water depth 20 m
Period of data collection Initiated in 2009

The buoy is located in the Clyde estuary, near Dunoon and provides measurements of dissolved oxygen, salinity, temperature, pH, chlorophyll and turbidity.

Maintenance takes place on a monthly basis using one of SEPA's support vessels.

Samples are mostly collected every 15 minutes, with occasional periods where a 10 or 30 minute sampling interval was collected.

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 Dunoon.
