Citizen science for cleaner beaches and a healthier horth sea 

Marine litter is one of the biggest threats to Dutch beaches and the North Sea ecosystem. At present, Dutch beaches contain an average of 282 pieces of litter per 100 meters of coastline. The European target is clear: bring this number down to just 20 pieces per 100 meters. Reaching this goal requires accurate data, effective policies, and action at both local and international levels. 

Goal of the project 

This is an innovative research project that empowers citizen scientists to help tackle this challenge. Twice a year, trained volunteers collect data on the type and amount of waste along the Dutch North Sea coast. The methodology used is: 

• Large-scale – covering the entire Dutch North Sea coastline 

• Accurate – using a standardized approach for reliable results 

• Internationally aligned – based on the OSPAR monitoring protocol, the global standard for marine litter research 

From data to action 

The collected data is visualized in the Beach Litter Monitor – an interactive online dashboard. This tool: 

• Shows trends in waste composition and quantity 

• Helps identify the most common litter sources 

• Supports policymakers, NGOs, and coastal managers in developing targeted, effective measures to reduce litter at its source 

Impact beyond the Netherlands 

While the project focuses on the Dutch coast, the Meet Mee methodology and tools can be applied in other coastal countries. This makes it a valuable model for international collaboration in protecting our seas.
