Marine sampling field manual for microplastics

An increasing number of organisations are undertaking research, monitoring, and data collection on the presence of plastic contamination in the environment. Recognising the imperative need for improved data harmonisation, there is a requirement to develop standardised approaches to allow reliable data comparison. This includes developing sets of reproducible practices and guidelines, covering all steps from sample collection, processing, laboratory procedures, and plastic characterisation. It also includes ensuring consistent terminology and data reporting parameters.

This manual is part of a suite of marine sampling field manuals that aim to facilitate reliable data comparisons across regions, and national and international collections, by implementing reproducible and comprehensive guidelines, covering all steps from sample collection, processing, laboratory procedures, and plastic characterisation. The approaches in these manuals provide methods for collecting data that are endorsed by researchers, managers, and technicians from multiple agencies with a variety of experience and subject-matter expertise.
