Ocean Career: The Ocean Cleanup Coastal Ocean Modeler

The Ocean Cleanup Logo
The Ocean Cleanup is a global nonprofit that develops and scales solutions to rid the world’s oceans of plastic, driving systemic change, and creating a lasting positive impact for people, wildlife, and the planet. To be successful, we rely on a thorough understanding of the ocean plastic pollution problem. The research team at The Ocean Cleanup aims at refining our understanding of the sources, transport and fate of ocean plastics. You will support our mission by implementing plastic dispersal models simulating the coastal transport of floating plastics from river and offshore sources to accumulation areas, helping us quantify the impact of our different projects in rivers and the ocean across the world.

THE ASSIGNMENT

  • Implementation of numerical Lagrangian particle tracking models simulating the dispersion of floating ocean plastics from river and offshore sources in target coastal areas.
  • Sourcing high resolution ocean circulation data in coastal domains and where no suitable model exists, supporting its development.
  • Designing site-specific source scenarios reproducing land-based and maritime emissions of ocean plastics into the marine environment.
  • Guide and support the design of field work campaigns based on numerical modelling results.
  • Refinement of modelling processes for simulating the fate of plastic pollution in coastal environments such as beaching, sinking degradation etc., based on learnings from the field and the literature.
  • Creation of reports for impact monitoring and peer-reviewed scientific manuscripts.
  • Production of intuitive and data-rich geographical data visualizations to orient our field scientists, simulate The Ocean Cleanup’s impact as well as engage internal and external stakeholders.
  • Attendance and contribution to international scientific conferences.

PROFESSIONAL QUALIFICATIONS

  • Masters or PhD degree in environmental sciences, physical oceanography, coastal oceanography, numerical modelling or similar.
  • At least two years of experience with numerical modelling (e.g. ROMS, CROCO, NEMO, Delft3D or similar) and particle dispersal modelling (e.g. Parcels) for material in the ocean (plastics, oil spills, sediments, fish larvae etc.).
  • Knowledge of coastal and hydrodynamic processes.
  • Proficiency with mathematical scripting and data science using software such as Python (preferred), R or Matlab.
  • Proficiency with Geographic Information System (GIS).
  • Proficiency in working with cloud computing (AWS) and git version control.

PERSONAL QUALIFICATIONS

  • Self-motivated, “can do” mentality.
  • Intrinsic motivation to work on our ambitious and meaningful goal.
  • Ability to clearly present, explain and summarize results.
  • Excellent communications skills in English.
  • Able to perform well in a fast-paced and challenging environment.
  • Flexible team player.
  • Ability to work independently.

Starting date: September 2026
