Please make sure you’ve read the Description sheet for this project before you undertake your dive. Please take a photo* of each sea fan you check, from both sides if possible. Once you return to your dive boat, make sure you record the GPS entry and exit positions for your dive from the skipper’s log. You’ll also need the mid-time of your dive (so that you can subtract the predicted tide height at that time to give your depth below chart datum).

* Photo filename must include: specimen number, site name, your name, date (e.g. 1_KnollPins_JohnDoe_2025-06-26)
