We visit Tyrell Bay, Carriacou (north of Grenada) to talk with Richard and Diane, owners of a local dive operation steps from the beach. They share how they built a relaxed, concierge-style shop—complete with a private jetty and dinghy pickups for cruisers—and why Carriacou's 38 dive sites keep photographers and explorers coming back. We break down two signature dives—Sisters Rock and Tropical Hill—plus the island's hands-on fight against the invasive lionfish (weekly culls, restaurant partnerships, even artisan jewelry). Most sites sit inside the Sandy Island Oyster Bed Marine Protected Area, where biomass and juvenile fish thrive. Hear how teaching local eels to predate lionfish reduced sightings on popular reefs and why Carriacou feels like "old-school Caribbean" diving done right.

On this first Expedition Grenada Sound Scene Tour, Joe Cocozza and explorer–filmmaker Jill Heinerth take you along from their breakfast table on Grand Anse Beach to the dive boat and back again. Jill shares the not-so-glamorous reality of red-eye flights, rushed uploads for a Japanese TV crew, and arriving in paradise on zero sleep. Joe and Jill paint an audio picture of their beachfront base at Coyaba Resort—bird nets, volcanic mountains, British-Caribbean vibe, and all. Then they walk the 85 feet to Eco Dive Grenada to meet marine biologist and dive operator Christine Finney, who gives a crash course on Grenada's geography, underwater volcano Kick 'em Jenny, and the island's leeward dive sites. In the afternoon, the team splashes into the Molinière–Beauséjour Marine Protected Area to explore Flamingo Bay Reef and the world's first underwater sculpture park. From long, shallow macro dives over fishy reefs to art installations transforming into living coral, this episode puts you right on the boat for Day One of Expedition Grenada.

A sitdown with legendary explorer, instructor, and authorJeff Bozanic to dissect what really kills rebreather divers — and how to break the accident chain before it reaches the fatal endpoint. Bozanic walks through the true incident picture for CCR vs open circuit, why early adopters skew the stats, and how advanced cave and deep wreck missions intersect with a steep learning curve on new life-support technology. Using detailed case studies (including a trimix instructor fatality involving wrong bailout gas, missing regulator, entanglement, and an isolation valve in the wrong place), he shows how most CCR deaths are not "one big mistake" but layers of small errors stacked together. Key technical topics include: Why rebreather incident rates appear ~10x higher than OC — and why that comparison is misleading How OC muscle memory (dropping a reg, response to gas emergencies) can be lethal on CCR The role of checklists: why long ones get ignored and how a short, targeted pre-dive CCR check could prevent 60–80% of known fatalities Human factors, complacency, and the "I got away with it last time" mindset in advanced dives Why 5-minute prebreathe "CO₂ tests" are functionally nonsense and how hypercapnia destroys your ability to self-assess Where rebreather tech, procedures, and training are headed over the next 20 years If you dive or teach CCR — especially in caves, deep wrecks, or mixed-gas environments — this episode is a blunt, data-driven look at accident analysis for rebreather diving and the mindset required to keep pushing the envelope without becoming a statistic.
