SDI Marine Ecosystem Awareness £110

Divers have a vested interest in protecting the marine environment. In many cases, divers do not have environmental information about local sites. This specialty is designed to increase the open water diver’s understanding of marine and freshwater environments, the problems facing these unique ecosystems, and the role that diver’s play in protecting our marine resources.

Cuttlefish are plentiful in Cornwall and always bring much joy to divers. Studies have shown that cuttlefish can display an extraordinary high level of intelligence on par with octopuses and yet despite this, they do not have the same levels of protection.

Upon successful completion of this course, graduates may engage in diving activities without direct supervision of the SDI Instructor* so long as the following limits are adhered to:

  • The diving activities approximate those of training

  • The areas of activities approximate those of training

  • Environmental conditions approximate those of training

*Note: Junior divers (ages 10-14) must participate in diving activities with a parent, guardian, or dive professional.

Also, the SDI Marine Eco Systems Awareness Diver certification counts towards a single specialty rating to achieve the SDI Advanced Diver Development Program.

  • Complete all open water requirements efficiently

  • Demonstrate mature and sound judgment concerning dive planning and execution

The purple/pink structure on the rock is a type of coral that can only be found in certain places around Cornwall. It is called an Elephant Sponge because it looks like elephant skin growing on the rocks but in some cases such as above, you can see what appears to be an elephants head with ears, eyes and a long trunk!
