Dive Briefing
"St. John's Coastal offers diving to 25 metres with an average depth of 16 metres in the reef and shore_dive environment. The site features high biodiversity with Cod, Lobster, Capelin, and diverse North Atlantic organisms. Access is by shore. The shore diving on rocky atlantic coast defines the diving experience at this unique Newfoundland site. 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."
