Metadata: CLiP Vanuatu Microplastics in water 2018
Abstract:
This dataset contains 2 csv files. One file contains data on microplastic abundance expressed in number of particles from 12 transects in Port Vila Bay and Mele Bay in Efate Island (Vanuatu) in 2018 with indication of volume and surface surveyed and transect info (duration, coordinates, comments). The file also contains information on blank used and contamination checks. The other file contains spectrum analysis of particles carried out with a ATR-FTIR. A READ-ME text file contains the description of columns content for the two csv files and a brief description of particles that have been analysed with the FTIR and photographed . A .zip file includes two folders with pictures of microplastics (particles with size less than 5 mm, Arthur et al., 2008) and macrolitter in diameter (particles with size greater than 5 mm).

| 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. | CLiP Vanuatu Microplastics in water 2018 |
| 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. | CEFAS34550f45-e558-432e-a300-2281705f7a3a |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS19784 |
| 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 | 2018-11-19 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2018-12-05 |
| 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'. | notPlanned |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The Commonwealth Litter Project (CLiP) supported Solomon Islands to take action on plastics entering the oceans. The assessment of microplastics in seawater was part of the action plan to define scientific baselines for future monitoring purposes and comparison. Samples were acquired towing a manta trawl from a 7.5m vessel for 30 mins at less than 3 knots. The trawl had a mouth of 60x18cm and a net mesh size of 335 micron. The amount of water filtered was measured by a General Oceanics mechanical flowmeter (one-way clutch). The sample was then rinsed in a jar through a 315 micron sieve and frozen at -18 degrees centigrade. High concentrations of organic matter were found in Mele Bay (coral spawning event). In the lab, visible plastic particles greater than 5mm were removed and analysed with a ATR-FT-IR to identify particle composition comparing their spectrum to a polymers library. The rest of the sample was chemically digested with 30 percent KOH:NaClO solution with an incubation of 1 day at 40 degrees centigrade. Samples were then filtered, stained with Red Nile dye and a digital image was acquired through a microscope. Number of particles was counted and corrected for blank samples. A subsample of particles (between 1 and 10 percent) was processed through a ATR-FT-IR. In case of samples with high organic content, a sieving stage through a 5mm mesh wad added at the beginning of the process. ATR-FT-IR is the attenuated total reflection Fourier Transform infrared spectroscopy. A Thermo Fisher Scientific Nicolet iS5 ATR-FTIR with an OMNIC software (version 9.9.473) was used and polymers were identified based on the percentage match of IR spectra to a polymer library. Only spectra matched greater than 70 percent were accepted Spectra were collected in the range 4000 – 650 1/cm at a resolution of 4 1/cm. |
