Internship - Global Model

The Ocean Cleanup

Posted on Feb 23, 2026

MISSION TO METRICS

In our mission to rid the world's oceans of plastic, we rely on a thorough understanding of the ocean plastic pollution problem. The research team aims to refine our understanding of the sources, transport, and fate of ocean plastics with the goal to increase the effectiveness of The Ocean Cleanup's actions. An important aspect of our research is understanding and mapping the input of plastic into the ocean via s in both space and time. For this, we are developing a novel global model to guide our efforts.

THE ASSIGNMENT

Your project will be centered around processes that prevent plastic from being transported through a system - either temporarily or indefinitely. This task includes creating a literature review, condensing its results into an expression that can be included in the existing model and finally testing this formulation by comparing the updated model results against observational data.

Being able to structure and document your research process and findings is a crucial part of this internship as the success of this project relies on a thorough and consistent work style.

"Our global model is at the intersection of academic outreach and providing data for internal decision making. By contributing to its quality, you are supporting two important goals for this organization, expanding our knowledge of and reducing the extent of plastic pollution." Ronja Ebner, data scientist & modeler.

RESPONSIBILITIES

You will be responsible for the improvement of a "state of the art" model by focusing on the aspect of sinks and interruption of plastic transport

This includes:

• Literature research
• Identifying a formulation based on acquired knowledge
• Implementing the expression into an existing model (Python)
• Comparing the results against observational datasets
• Documenting the process and reasoning

PROFESSIONAL QUALIFICATIONS

• Experience with Python is crucial
• Familiarity with ine transport processes is very beneficial
• Experience with object-oriented programming is beneficial
• Experience with jupyter is beneficial
• Experience with GitHub is beneficial
