| Internal code | Internally assigned metadata identifier | 3855 |
| 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. | Dataset for ROAME ST014 Sources, sinks and hazards of micro-plastics in Scotland’s seas |
| 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. | Marine_Scotland_FishDAC_12324 |
| Resource Identifier | This is the code assigned by the data owner. | Marine_Scotland_FishDAC_12324 |
| 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 | 2013-04-01 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2020-01-31 |
| Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | 200.00 |
| Spatial resolution unit | This describes the unit of spatial resolution which for distance must be metres. | http://standards.iso.org/ittf/PubliclyAvailableStandards/ISO_19139_Schemas/resources/uom/gmxUom.xml#m |
| 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'. | Not Planned |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Samples were collected using Marine Scotland Science protocols and SOPs. Sea surface water samples were collected with a 335 µm neuston net mounted on a catamaran swimmer body (Neuston Net acc. to David/Hempel Model 300) from January 2014 up to and including January 2020 using Marine Scotland Sciences’ research vessels MRVs Scotia and Alba na Mara and the Scottish Environment Protection Agency vessel the RV Sir John Murray. The primary purpose of these surveys is to collect water, sediment and fish samples for nutrient, chemical and biological effects monitoring. Piggybacking microplastic sampling on surveys with a different sampling purpose is the usual scenario, due to the expense of a dedicated survey and helps maximise the use of ship time. Towing times varied from 15 minutes to over 1 hour, depending on the available time and/or sea surface conditions. The average speed of the ship during towing was 5 knots (2.6 ms-1). Once towing was completed the net was rinsed into the cod end and the material in the cod end transferred to a sieve stack consisting of 5 mm and 125 µm aperture sieves and a base pan. The material was rinsed through the 5 mm sieve using fresh water. The material collected in the 125 µm sieve was examined and the microplastic particles collected and counted. Particular care was taken to check for microplastics adhering to larger material such as seaweed. The examination and picking of microplastics was carried out by two people, using a lighted magnifier, as a cross check that everything identified as plastic was collected. Potential microplastics were counted in categories – fibres, film, beads, nurdles, fragments, polystyrene and paint flakes. Although not included in this assessment material greater than 5 mm in its longest dimension was also collected and counted in the same categories. Post survey, a selection of microparticles were analysed by microscopy Fourier Transform Infrared Spectroscopy (microFTIR) to confirm that they were microplastics. Potential hotspots for microplastics were identified in the surveys. |
