Seamounts and Deep Walls

Manned submersibles allow making direct observations in steep and highly structured grounds in deep-water environments whilst providing high maneuverability for surveys.

The LULA1000 has carried out video surveys at seamounts and along vertical walls near Pico and São Jorge islands, revealing new evidence of unique coral gardens, sponge aggregations and a diverse associated fauna. These habitats are real hotspots of deep-sea marine life and need to be studied better. Cold-water coral habitats are considered Vulnerable Marine Ecosystems of high conservation value. They have a wide diversity associated fauna, such as fish, echinoderms, crustaceans and other invertebrates.

Several cold-water reefs and gardens have been documented and mapped with the LULA1000 submersible.
