Project Baseline is a call to action for the most important environmental cause of our time: to protect and sustain the world's rapidly diminishing fresh and marine ecosystems, and the treasures contained within them.

Project Baseline's goal is to foreground the critical condition of our most valuable natural and cultural underwater resources by developing and sustaining a record that charts underwater conditions over time. Participating in Project Baseline is a way for all divers of all levels to validate their training, create and grow local communities, and preserve the underwater world.
