In order to achieve a successful cleaning of our oceans, we need to gain more knowledge of riverine plastic debris through conducting research. The River Research Intern will support the development, testing, and application of various riverine plastic models.


The Ocean Cleanup’s river research team aims to provide global estimates of riverine plastic debris using a combination of (1) fundamental experiments, (2) targeted fieldwork and (3) modeling exercises. Understanding riverine plastic composition, transport, sources and sinks help us to better predict the inflow of plastic waste into the ocean. We are looking for river research interns, year-round, to assist the current team.

Tasks will include:

  • Collect and analyze plastic and hydrological data for specific rivers
  • Plan and execute field measurements
  • Help improve The Ocean Cleanup’s measurement methods for river monitoring
  • Report back upon your findings, including recommendations for future research

Current open specific assignments include:

  • Plastic transport model development to simulate the spatiotemporal variation of plastic transport along rivers
  • Observing and conceptualizing the vertical distribution of riverine plastic transport


  • Currently a student at a university (of applied sciences) in for example environmental sciences, hydrology, geosciences, water management or similar
  • Preferably experienced with planning and executing (hydrological) fieldwork
  • Experienced with finding, processing, analyzing and visualizing data
  • Ideally some experience with Python, R, or MATLAB
  • This internship can be combined with writing a BSc or MSc thesis


  • Independent work ethic (and knows when to ask for help)
  • Problem solver
  • Practical (for example: you can fix your own bike and enjoy building things)
  • Strong command of English, verbal and written
  • Intrinsic motivation to work on our ambitious and meaningful goal
