Metadata: DAERA Annual Chlorophyll a Survey (2008-2017)
Abstract:
The chlorophyll a survey is an annual assessment of the Chlorophyll a concentration in micrograms per litre found in surface waters in coastal and transitional (estuarine) waters around Northern Ireland. Spot samples are taken at established sample sites and returned to the laboratory for analysis. The dataset contributes to Water Framework Directive (WFD) classification, as well as providing a eutrophication indicator under Nitrates Directive (ND), and Urban Waste Water Treatment Directive (UWWTD). Selected samples are submitted to the MERMAN database for inclusion in the CSEG (Clean Seas Evidence Group) work programme. The data held in MERMAN fulfils the UK's mandatory monitoring requirements under the Oslo and Paris Convention (OSPAR), Joint Assessments and Monitoring Programme (JAMP). Within DAERA, this survey forms part of the Marine Phytoplankton and Chlorophyll work programme (MM(YY)-14)

| Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | DAERA Annual Chlorophyll a Survey (2008-2017) |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | 2fd970bce0d98968d0c9017bf049571e |
| Resource Identifier | This is the code assigned by the data owner. | DAERA-CHL |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | dataset |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 2008-01-22 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2017-12-06 |
| Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | inapplicable |
| Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | annually |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Samples are collected from a boat by surface water collection in sterilised glass nalgene bottles. Samples are filtered within 24 hours under vacuum filtration, using Whatman GF/C47mm glass microfibre filter papers. Filter papers are left overnight at 4 degrees celcius in the dark with cold acetone to extract. Analysis is performed in house on a Turner Designs 'Trilogy' fluorometer. Samples are analysed in duplicate and the average is reported. Solid standard QCs are used at the start and end of runs and reported on Shewart charts. Calibration is carried out at 4 points using RS AQUA liquid standards. Participation in QUASIMEME is mandatory for all staff who take part in the analysis. In house training is provided by competent staff members. Analysis is of Chlorophyll a only. |
