About hammerdirt About this projectHammerdirt is a nonprofit associ-ation with no political or religious affiliations We are driven by our desire to create an environment that leverages technology and citi-zen participation to solve problems now and in the futureWe prefer action to words and our projects reflect this philosophy Collaborative by nature we actively seek feedback from all interested parties and we integrate that feed back into our operations

The project is based on a statistical approach and requires data collection regularly and systematically In order to establish a trend the data collected must have temporal quantitative and geographical parametersOnce collected the data can be used to evaluate the effectivenes of litter mitigation strategies The data is compared over time to demonstrate the evolution of the quantity and type of litter found at precise locations

We use an international standard developed by the EU and UNEP for categorizing the litter found during a litter-survey Our data is compatible with the Marine Litter Watch pro-gram

Our method is simple

1Separate material into categories

2Count each item in each category

3Record quantities

We have refined our methods and we use common technologies to mini-mize administrative overhead Data entry is completed on site and is im-mediately exploitable
