Ocean Travelers - Ocean Travelers

The Ocean Travelers project is a citizen science project promoted by theSmithsonian Environmental Research Center and by the Chilean NGO Cientificos la Basura and represents a joint effort of multiple institutions, which values international collaboration and the involvement of a wide community of stakeholders.


The aim of the project is to identify organisms (epibionts) which travel across the ocean on floating objects, for example on logs and wooden boards, pumice, seeds and other organisms, and which more recently also use plastic and other materials as substrates created by Man. Unlike natural materials, new artificial habitats persist for a long time on the surface of the ocean, and allow epibionts to travel great distances, reaching new continents and remote areas where they can become invasive species.

The aim is to identify these organisms, their origins and abundances, with a view to protecting local marine communities.

1. How much marine litter reaches us from elsewhere?

2. What organisms are carried by marine litter? And how many ? 

3. How does the amount of marine litter and epibionts on the beaches of the world vary?

Ocean Travelers

Do you want to participate in the 1st international sampling campaign?

We are looking for volunteers who want to coordinate sampling on beaches in Portugal and in the Portuguese-speaking countries. Friends, family, students, everyone can participate.

As a group coordinator, you must register and have special attention to the guide and videos that explain how to proceed to collect samples in order they can be included in this study. You will be responsible for selecting the site to be sampled, organizing the team of volunteers and sending the data. If you want to participate individually you can also register.


The methodology in Portuguese will be made available soon.
