Demersal surveys performed with bottom longline during research cruises around Azorean islands and several seamounts. Surveys conducted annually (few exceptions) from 1996 to 2013.

Annotations of species recorded on video by Remote Operated Vehicle (ROV) during dives performed in the Faial-Pico Channel in the Azores archipelago, Portugal. Videos were recorded between 80 and 250 meters depth.

Recorded sightings of seabirds close to the boat and/or interacting with the tuna fishing, while capturing the tunas.

Sightings of turtles were recorded daily, at 6 different fixed periods (snap shots), when the boat was in navigation or search mode.

Tuna species caught and commercialized by pole and line tuna fishery boats.

Recorded sightings of seabirds close to and/or interacting with the boat, while capturing the live bait.

Sightings (snap shots) of marine mammals collected by Biosphere Expeditions collaborators specifically for POPA. Since 2004 Biosphere Expeditions (www.biosphere-expeditions.org) collects data for POPA in the Azores central group in April and May.

Reference collection of the IMAR/DOP-UAz, consisting in several taxa preserved with different methods and collected mostly in the Azores area. The reference collection has been created in order to be a referential of marine species of the Azores, both common and rare. Thus, new occurrences could be compared with new ones. Therefore, material in the collection can be useful for new scientific and taxonomic studies.

Non declared species that are caught during fishing events (rejected, food for the crew, etc).

Sightings (snap shots) of sea turtles collected by Biosphere Expeditions colaborators specifically for POPA. Since 2004 that Biosphere Expeditions (www.biosphere-expeditions.org) collects data for POPA in the Azores central group in April and May.
