SUBNOTE (Notice to Submariners) provides advance notification of local restrictions, required approvals, and safety considerations for submersible operations, helping operators plan dives responsibly and safely. Familiarity with SUBNOTE publications also helps submariners protect the hobby, preserve access, and maintain the integrity of the submersible community.
