Dive Site: Joelle’s Reef

About Joelle’s Reef

Joelle's Reef is a renowned seamount located in the pristine Kimbe Bay, Papua New Guinea, named after the daughter of liveaboard skipper Alan Raabe. Positioned close to the open waters of the Bismarck Sea, it is one of three iconic seamounts in the bay that are celebrated for their incredible marine biodiversity. This site features a pinnacle reef rising from considerable depths, its summit reaching around 16 to 20 meters from the surface. The topography is characterized by exceptional hard coral cover, sea whips, gorgonians, and a multitude of reef fish, creating a dense biomass and a visually stunning underwater landscape. The seamount acts as a self-contained ecosystem, attracting both abundant reef life and larger pelagic species. Divers can anticipate encounters with schooling barracuda and bigeye trevally, along with resident species like bumphead parrotfish and Napoleon wrasse. Pygmy seahorses can be found in the sea fans, while a variety of anemones host clownfish, shrimp, and crabs. The reef thrives with an eclectic range of corals and sponges, making it a hotspot for macro and wide-angle subjects alike. Diving Joelle's Reef typically involves exploring the pinnacle, observing the dense reef fish populations, and watching for pelagics in the blue. Conditions often feature clear water with minimal currents, although the site is best dived when conditions allow, due to its exposure to the open sea. It offers a captivating experience for divers seeking vibrant coral gardens and diverse marine encounters.

Conditions & Currents

Joelle's Reef, being a seamount located near the open waters of the Bismarck Sea, is primarily dived when conditions are favorable, allowing for its accessibility. While the site is often characterized by clear water and no current whatsoever, according to some reports, its exposure means that currents can occasionally be present, influencing dive plans. When currents are mild, divers can leisurely explore the pinnacle, while stronger flows would necessitate drift diving techniques. Visibility is typically excellent, often exceeding 30 meters, contributing to wide-angle photography opportunities. Water temperatures in the Bismarck Sea average around 31°C, eliminating concerns about thermoclines at typical dive depths. Entry is usually via tender boat, with divers descending along the reef structure. Dive operators coordinate schedules to ensure that Joelle's Reef is not crowded, providi

Dive profile & how the dive runs

Dives at Joelle’s Reef typically begin with a descent onto the pinnacle’s shallower sections, which rise to about 16 to 20 meters from the surface. Divers often explore the top and sides of the reef, characterized by abundant hard corals, sea whips, and a high biomass of reef fish. The route usually involves circling the seamount, observing smaller creatures like pygmy seahorses in sea fans and the symbiotic life within the numerous anemones, before gradually spiraling deeper along the reef’s slopes. Attention is also paid to the blue water surrounding the pinnacle, where schools of bigeye trevally and barracuda are frequently sighted. The dive progression is generally slow, allowing ample time for observation and photography, with the deepest points reaching around 30 meters. The turn point is determined by air consumption and no-decompression limits, allowing for a reverse profile ascent. Safety stops are conducted in the shallower sections of the reef, usually around 5 meters, where divers can enjoy the vibrant coral gardens and reef activity before surfacing.

Underwater photography

Joelle's Reef offers exceptional opportunities for both wide-angle and macro photography, thanks to its pristine corals and diverse marine life. For wide-angle shots, a fisheye lens or wide rectilinear lens is recommended to capture the expansive hard coral coverage and the dramatic scale of the seamount, particularly with schools of barracuda or trevally in the background. Abundant light from strobes is crucial to bring out the vibrant colors of the corals and sponges, which thrive in the clear waters. Macro photographers will find a wealth of subjects, including pygmy seahorses nestled in sea fans, various species of clownfish in their anemone hosts, and a host of other critters like shrimp and crabs. A macro lens with a diopter can be advantageous for capturing the intricate details of smaller subjects. Careful buoyancy control is essential to avoid disturbing the delicate corals and to position yourself for optimal shots. Patience is key when photographing shy subjects like pygmy seahorses, requiring a slow and non-intrusive approach.
