Diving P.J.'s Passage, Port Moresby: Eagle Rays and Sharks

P.J.'s Passage, located in the vibrant waters of Port Moresby, presents itself as a classic channel dive, a conduit where the ocean's lifeblood flows. As you descend, the surrounding reef structures guide you into the main thoroughfare of the passage. The dynamic nature of this site, shaped by the tidal movements, promises an ever-changing landscape of both reef residents and passing pelagics.

The dive profile here typically involves a drift, leveraging the incoming or outgoing tide to explore the passage's full extent. Starting your descent, you'll find the reef gently sloping, transitioning into deeper channels and plateaus. These varied depths, stretching from 10 meters down to 40 meters, create distinct ecological zones, each hosting its own set of marine life and offering different perspectives on the passage's activity.

It's within this current-swept environment that P.J.'s Passage truly distinguishes itself. Keep a keen eye on the blue, as this is where the larger inhabitants often cruise. The strong currents act as a conveyor belt, bringing a rich supply of nutrients that attract a notable congregation of marine predators. These conditions allow for compelling encounters with the site's larger inhabitants, including the majestic eagle rays (Aetobatus narinari).

Beyond the eagle rays, the passage is also a known haunt for sharks. While specific species are best left to surprise, the presence of these apex predators underlines the health and vitality of this underwater ecosystem. Divers also have the opportunity to spot mobula rays (Mobula mobular), graceful flyers that glide through the current with effortless precision, adding another layer of excitement to the dive.

The interaction with these pelagic species, particularly as they navigate the currents, is what defines the experience of P.J.'s Passage. The ebb and flow of the water dictate their movements, creating a natural ballet that unfolds before your eyes. Maintaining situational awareness and practicing good buoyancy control are key to fully appreciating the spectacle and embracing the natural rhythm of the passage.
