Welcome to the beach-litter section
This is a Management tool:
Based on hundreds of observations. Because to manage it, you need to measure it.
Pragmatic action:
Each trash sample remediates the problem(a little bit). Data collection is for tomorrow. Removing trash is for today.
Water is better without trash:
A clean beach is a guaranteed value.
Reproducible research:
You can DIY this if you like, gather your own data or use ours. Updated every time somebody makes a request to the server.
Methods and Analysis
Methods based on two programs:
Marine Liiter Watch and OSPAR. A brief description of how we define a 'beach-litter-survey':
Probability of garbage
Year over year results from beach-liiter-surveys on Lac Léman. Expressed as the probability distribution of finding a quantity of trash per meter of lake shore.
Comparing Swiss lakes
Comparing the survey results from 15 different lakes in Switzerland.
History and projects
All good things take time:
The project was built from the ground up. From the first set of observations noted on paper to developing the application that allows all stakeholders to use the data as they see fit.
Open access is a critical resource
