Iceland underwater depths:

Slowly but surely, Iceland is torn. The island is located on the Mid-Atlantic Ridge, straddling two continental plates. As they move away, the earth fracture faults and fissures through the country. Some stay dry and others open up the cold water table. Length up to 400 m to a maximum depth of 60 m.

Jónína Herdís Ólafsdóttir, biologist and diver explores the underwater fissures known. While they may seem devoid of life, just look more closely to see fish among the rocks spinning. It is often dwarf trout knights, but there are sometimes bigger trout, from neighboring lakes. Algae like green fluorescent Tetraspora cylindrica leave their mark surrounding; thick cyanobacterial mats cover the walls, providing food and shelter to tiny invertebrates.

The young scientist and his team hypothesized that the cave crustaceans, are among the few species endemic to this island geologically very young, lived in the cracks. They ended up flush in one of Huldugjá, 40 m deep. A discovery that encourages further exploration of this mysterious world.
