This dataset contains two CSV files. One CSV file reports locations and
technical details for the cores, along with their slices, subsamples and the
number of microplastic particles and fibres recorded in each 5g sample
processed. Details of how the cores were sampled and processed can be found in
the publication and its supporting information.
The second CSV file contains x-y data for the micro-ATR-IR analysis of
representative particles picked from some of the filters, to provide some
numerical data on polymer types and fractions of Nile Red positive particles
that could be positively identified as plastics (positives), those that were
biological in origin (false positives) and those that could not be confidently
identified. Details of the procedure for this appear below. Images of the
particles along with their IR spectra can be found in the ESI accompanying the
publication.
