Internship (River Analysis)

The Ocean Cleanup

Rotterdam, , NL


The mission of The Ocean Cleanup is to rid the world’s oceans of plastic. Therefore, we also need to ‘close the tap’. Our research indicates that 1000 rivers are responsible for 80% of riverine plastic influx into the ocean. The River Analysis Intern will collect as much data as possible on these rivers and classify them.

“The Data & Monitoring Team supports the deployment and development of Interceptors by researching the spatial and temporal behavior of plastic in rivers and providing data on rivers where deployments are planned. We collect data, create models, and collaborate with universities across the globe to obtain accurate data and knowledge on plastic emitting rivers. I’m looking forward to working with a student with affinity with hydrology and spatial analysis to improve our global analysis on plastic polluting rivers” – Lourens Meijer, Team Lead Data & Monitoring


Our Global River Model identified the 1000 rivers responsible for 80% of plastic emissions. In order to be able to classify these rivers and deploy the Interceptor in the most suitable rivers, additional data on these rivers is required. A structured database on these rivers, containing hydrological data such as tide, discharge, geographical data, and socioeconomic data needs to be further elaborated. We are looking for a student who is experienced with analyzing large spatial (satellite) datasets and processing this data within a Geographical Information System (GIS). Intelligent solutions to map and classify boat navigation on rivers, variable width and flow velocities need to be further developed.

This assignment will require you to spend five to six months in the office in Rotterdam, the Netherlands.
