Backyard Buoys delivers wave data to those who need it the most. We are a partnership of regional ocean observing systems (NANOOS, AOOS, PacIOOS), Indigenous communities, and a sensor company (Sofar Ocean). Together, we are co-designing wave buoy programs that are community-led and community-stewarded, working in partnership to assure technical training and sustained support. Backyard Buoys is funded by the National Science Foundation's Convergence Accelerator Program.
