Discover a World Under the Waves

The extreme amount of rainfall in the fiords results in a freshwater surface layer that can be as deep as seven metres. The run-off from the surrounding mountains collects vegetable particles, which are responsible for the tannin-like colour of the water. This creates a light barrier and encourages deep-water plants and animals to thrive at shallower depths.

The marine reserves have an impressive variety of habitats and species from sponges, lampshells (brachipods), starfish lobsters, rock crabs and fish, to some of the world’s biggest populations of black coral trees. This black coral - said to be more expensive than diamonds - can be more than 300 years old.

What is an ROV? 

An ROV is an unoccupied underwater robot that is connected to a vessel, via a series of cables. The cables transmit command and control signals between the operator and the ROV, allowing remote control of the vehicle.
