Open source plankton monitoring and analysis equipment PlanktoScope

Plankton help remediate 30-50% of the world's carbon dioxide and provide the foundation for the global food chain, making up the world's largest daily movement of biomass as it travels across the ocean. The shapes, colors, and movements of these billions of creatures are as vast as the oceans that sustain them. Understanding plankton is crucial to understanding the world around us and our impact on it.

One obstacle to this type of research is the sheer size of the area to be explored, as well as limited resources for research fleets and specialized equipment. By developing a method to scale up high-quality visual exploration and documentation, we can greatly increase our understanding of the complex web of life around us, and how we in turn influence it.
