SeaPaCS deliverable - protocol for plastic monitoring in citizen science

  • 1. ROR icon University of Siena
  • 1. University of Turin


This protocol in English and Italian is a deliverable of the SeaPaCS project (Participatory Citizen Science Against Marine Pollution), funded by IMPETUS (project ID 101058677). The protocol has been freely adapted from "LADI and the Trawl" by Coco Coyle with Melissa Novaceski, Emily Wells and Max Liboiron, as published by the Civic Laboratory for Environmental Action Research, August 2016 (in the protocol referred to as "original document", freely available at ). 

The protocol, in both languages, consists of three parts: 1) how to build a DIY low cost manta trawl device (LADI - Low-Tech Aquatic Detection Debris Instrument) to monitor plastic pollution,  adjusted to materials availability and costs in Italy; 2) how to monitor (the sampling itself and towing procedure); and 3) how to categorize plastic debris back on land. 

The protocol will be adopted by the sailing school of the Italian Naval League (Lega Navale Italiana) in 2024 who will be donated a low cost manta trawl device (LADI) to monitor plastic debris along the coast of Anzio (Rome, Italy), as a follow-up activity of SeaPaCS project. 

A video tutorial (in Italian only) is available on
