The 100 Island Challenge is a collaborative effort based at Scripps Institution of Oceanography to describe the variation of coral reefs from across the globe. We combine classical field surveys with innovative imaging and data technologies to archive reefs digitally and watch how populations change through time.

A NOTE FROM THE TEAM: The 100 Island Team has made necessary adjustments due to current public health and safety concerns. With field seasons canceled or postponed and our team members working remotely– we encourage our colleagues, collaborators and followers to take care of themselves and their communities while fostering conversation and engagement.
