Automatically checked observations from dives during the past 14 days. Three reports are visible at a time; scroll for more.A report that passes the automatic checks will appear here with the dive date, diver’s display name, and temperatures at each depth.
Reports are automatically checked for plausible dates, depths, and temperatures. They are observations, not forecasts; confirm conditions before diving.

Before you arrive
Access notes
Technical dive only. Confirm current conditions, access, gas plan, decompression plan and operator requirements before departure. Published coordinates are research references, not navigation instructions.
Plan within your training
Conditions and hazards
Depth beyond recreational limits, decompression obligations, cold water, limited light, changing visibility, entanglement and possible wreck overheads. Penetration requires separate wreck-penetration training and planning.
Independent resource notice
This record is a starting point for independent verification. Access, closures, moorings, weather, currents, depth, visibility, operator availability, and site conditions can change without notice. Confirm current information with the responsible operator, property owner, managing authority, or another qualified local source before planning or attempting a dive.
