  • Submerged or partially submerged sea caves

    Typically associated with reefs, caves that are either underwater all the time or welcome the sea at high tides, caves provide a habitat for a wide variety of plants and animals.

  • Reefs

    Areas where the bedrock, stable boulders and cobbles or structures created by animals arise from the surrounding seabed. They attract and provide a home to a huge variety of plant and animal life.

Some Seasearch diving has taken place in the site over the geologically-diverse reef habitats and communities. The chalk reefs on the south-western side of the island (the Needles and Freshwater Bay) and limestone/sandstone reefs in the south-east off Bembridge have also been explored by volunteer divers. It is a challenging site to dive, exposed to the prevailing winds from the south-west along the English Channel.
