Metadata: CLiP Vanuatu Microplastics in sediment 2017
Abstract:
This dataset contains 3 csv files. One file contains data on microplastic abundance expressed in number of particles per 5g dried sediment from 14 grabs collected on Efate Island (Vanuatu) in 2017. One file contains spectrum analysis of particles carried out with a ATR-FTIR. A READ-ME text file contains description of columns content for these two csv files. One .zip file includes a csv file with the description of the plastic particles larger than 5mm (macroplastic) and pictures. Microplastics are plastic particles with size < 5 mm in diameter (Arthur et al., 2008).

| 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. Number of microplastic items per 5g dried sediment in samples from 14 grabs in Efate Island (Vanuatu). Sediment samples were taken from 6 riverine locations and five coastal ones. Samples were dried for 3 days (<50 degrees centigrade) and weighted. Density separation using NaCl solution and a centrifuge, filtering the supernatant. This was followed by a chemical digestion with a KOH:NaClO solution for 3 days at 50 degrees centigrade whilst shaking. Plastic particles were then stained with Nile Red dye and a digital image was acquired through a microscope. Microplastic particles were then counted and a subsample of particles (between 1 and 10%) was processed through a ATR—FTIR to identify particle composition comparing their spectrum to a polymers library. The presence and number of particles of plastic >5mm was also noted for each sample. |
