Only 1 or 2 spots available. A California Ships to Reefs sink site survey, data collection dive(s) will be voluntarily performed by HardcoreDiveTeam and The Goby Dive Boat . The exact dive date will be updated according to plans. The site(s) are in 100’+ so advanced divers only. What we’ll be doing: collecting pin-point depth data coordinates, bottom samples, fish counts recordings via video/stills. 1 or 2 sink site (1 square mile to work in, 95’ to 130’ in calculated grids) dives, in teams of 2. Then 1 dive at Star of Scotland (75’) or 1 dive at Marina del Rey artificial reefs (45’-50’.) We can fill these spots in seconds but will let the So Cal diving community get a chance at going. Details of the day, and what doors it can open can be found here or facebook page. If you love diving, you will be glad you looked into this! Guaranteed.
