    Dive Briefing

    "Sable Island Expedition offers diving to 35 metres with an average depth of 22 metres in the wreck and reef environment. The site features high biodiversity with Grey Seal, Cod, Lobster, and diverse Atlantic organisms. Access is by boat with a 120-minute boat ride. The Atlantic conditions provide diving with remote expedition to offshore island. Divers should plan their descent carefully, monitoring depth and air consumption throughout the dive. The site rewards patient divers who take time to explore the smaller features and crevices where marine life shelters. Buoyancy control is essential for protecting the delicate marine ecosystems and maximising bottom time in the cold water environment. Communication with dive buddies is important given the cold water conditions and potential for rapid environmental changes. Safety stops should be planned conservatively given the cold water exposure and potential for thermoclines at depth. The dive plan should include careful assessment of entry and exit points, particularly for shore dives where rocky terrain requires appropriate footwear and caution. Underwater navigation follows the natural contours of the reef or wreck structure, with divers maintaining close buddy contact throughout the dive. Emergency procedures should be reviewed before entry, including the location of the nearest exit point and the availability of surface support. Post-dive warming is essential given the cold water exposure, with hot beverages and warm clothing readily available on the boat or at the shore base."
