Mulberry Marine Experiences is an SSI-affiliated centre located in Selsey, West Sussex. Unlike traditional dive shops focused solely on scuba, this centre places a significant emphasis on the connection between the diver and the marine environment through snorkeling, freediving, and marine ecology.
Operating as a social enterprise, the centre focuses on ethical and sustainable ocean experiences. Their approach integrates citizen science and community involvement into their core activities, ensuring that local marine conservation is a central part of their mission.
The teaching programmes are designed for a wide demographic, ranging from junior clubs and children's ecology groups to dedicated sessions for those over 50. Whether you are looking for structured freediving training or guided marine life walks, the instruction is rooted in a deep understanding of the local Sussex ecosystem.
The course catalogue is extensive, with a particular strength in freediving and marine biology. SSI certifications are available for Snorkel Diver, Basic Freediver, and more advanced disciplines including Free Immersion and specialised Training Techniques (Freediving). They also offer the Ocean Mermaid programme.
For those looking to deepen their scientific knowledge, the centre provides a suite of ecology courses. These include Manta and Ray Ecology, Shark Ecology, Sea Turtle Ecology, Marine Mammal Ecology, and Nudibranch Ecology, alongside foundational courses in Fish, Coral, Invertebrate, and general Marine Ecology.
The centre provides complete equipment hire for most activities, though they recommend that divers bring their own mask and snorkel for certain sessions to ensure a perfect fit.
Training is conducted in various environments, including pool sessions during the winter months and open water sessions throughout the rest of the year. For those pursuing freediving, the availability of pool-based training provides a controlled environment to master technique before moving to the coast.
Selsey Bill and Hounds Marine Conservation Zone is a highly biodiverse area ideal for snorkeling and freediving exploration. It serves as a vital habitat for a wide array of local marine life.
Bognor Rocks at the Aldwick end offers a rocky terrain that is perfect for practicing snorkeling skills and observing specialised marine life in the crevices.
East Beach in Selsey provides an accessible shore-based site for exploration, featuring mussel beds that support a variety of smaller organisms.
And some of the dive sites the centre runs.
The marine life in the Selsey area is remarkably diverse, ranging from large pelagics to delicate invertebrates. You can encounter rays, various species of sharks, and resident or visiting marine mammals such as whales, dolphins, and seals.
In the water, you will find a variety of fish species, including those typically found in UK waters, as well as sightings of turtles. The presence of corals and diverse marine invertebrates adds significant texture to the seabed habitats.
For those interested in macro life, the area is an excellent place to observe nudibranchs and various other invertebrates. The rocky sections and mussel beds provide the necessary structure for these smaller, more specialised species to thrive.
Open water sessions are heavily dependent on weather conditions, particularly regarding swell and sea state. While snorkeling and freediving can take place year-round, certain specialised programmes, such as the Ocean Mermaid sessions, are focused on the summer months from June to September.
Winter months are typically utilised for pool-based training to ensure consistent skill development regardless of the coastal conditions.
