Metadata: Volumes, dredged area measurements and estimated contaminants of material disposed at licensed offshore sites around the UK coast from 2000 to 2020
Abstract:
The dataset contains data related to registered offshore sediment disposal sites around the UK coast and includes volumes of disposed material, dredged areas, calculated levels of contaminants in the disposal material and licence details. Data were collated for the years 2000 to 2020. The Centre for Environment, Fisheries and Aquaculture Science (Cefas) on behalf of Department for environment, food and rural affairs (Defra), report these data for the United Kingdom (England, Scotland, Wales, Northern Ireland), Jersey, Guernsey and Isle of Man, annually as a UK obligation under both the London Convention/London Protocol on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter (LCLP) and the Convention for the Protection of the Marine Environment of the North-East Atlantic (OSPAR).

| Other details | ||
| Internal code | Internally assigned metadata identifier | 9556 |
| 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. | Volumes, dredged area measurements and estimated contaminants of material disposed at licensed offshore sites around the UK coast from 2000 to 2020 |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | OSPAR Returns |
| 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. | CEFAS43704848-4285-4278-bc29-1a80983dfdc4 |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS2970 |
| 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. | series |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 2000 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2020 |
| 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. | The dataset was created by combining the regulatory data collected around the UK, including England and the Welsh, Scottish, Northern Irish and Isle of Man devolved administrations, with quality assurance and calculations of contaminant loads carried out by Cefas. Regulatory data includes disposal returns submitted to individual regulatory bodies by the licence holders, supplemented by chemical and physical analyses data of samples taken to characterise the disposed material. This information is provided annually to Cefas by the individual bodies. Cefas then collates the various returns datasets and carries out quality assurance. Cefas also calculates the contaminant loads from the sample analysis data, and scales up to individual sites to estimate how much contaminant has been disposed of. Reports produced by Cefas with the finalised data are submitted to LCLP and OSPAR secretariats on behalf of Defra. The spatial extents of the licensed disposal sites are described by the following published metadata `https://data.cefas.co.uk/view/407`_. Disposal volumes are measured using on board volume calculations and reported to the Regulator(s) annually. Contaminant information is measured in samples using established techniques for marine sediment (see `https://www.gov.uk/guidance/marine-licensing-sediment-analysis-and-sample-plans`_ for example) and are then weighted by dredged area proportions and scaled up to the disposal volume. .. _`https://data.cefas.co.uk/view/407`: https://data.cefas.co.uk/view/407 .. _`https://www.gov.uk/guidance/marine-licensing-sediment-analysis-and-sample-plans`: https://www.gov.uk/guidance/marine-licensing-sediment-analysis-and-sample-plans |
