Interest in the deep seas has increased dramatically in the last decade, due to the potential presence of natural resources. Although Colombia holds a large submerged territory, knowledge of the seabed and its biodiversity beyond a depth of 1000 meters is very limited. During 2015-2017, Anadarko Colombia Company (ACC) carried out hydrocarbon exploratory activities in the Southern Colombian Caribbean, at depths between 375 m and 2500 m. As an opportunistic result from these activities, several organisms from different phyla were spotted in ROV and towed camera surveys. We analysed a total of 9h 9min 26sec of video and 5066 photographs, looking for benthic and pelagic megafauna. The images were separated by Phylum and Class, and the fishes were identied to the lowest possible taxonomic level. The data presented here corresponds to 250 occurrences of deep-sea fishes and 190 were identified from order to species. This is the first of a series of datasets reporting visual confirmations on the occurrences of deepsea organisms in the Colombian Caribbean.Sampling Description
Study Extent
The exploratory wells and areas of interest are localized in the South-western Colombian Caribbean, at depths between 375 m and 2500 m. In general, wells and areas of interest are approximately 54 to 74 off shore from the nearest point in the Caribbean coast of Colombia.Sampling
Survey areas of interest were assessed using 25 towed camera transects. These transects registered seafloor features, during 3-hour surveys, taking still images every 20 seconds. Benthic and pelagic megafauna specimens were recorded in the images.Quality Control
Still images and pictures of towed camera were analysed twice by the same expert, who did preliminary identification to phylum and class. All fish images were then identified to the lowest possible. When in doubt about the identification, additional experts were contacted and the images were sent to them in jpg format for towed camera photographs.Method steps
- Towedcamera images: A total of 5,066 photographs, looking for benthic and pelagic fishes were analyzed. For each fish, coordinates and depth were registered and identified to the lowest possible taxonomic level.
Taxonomic Coverages
The data presented here corresponds to occurrences of deep-sea fishes from the South-western Colombian Caribbean, spotted over soft bottoms at depths between 375 to 2565 m. The taxonomic coverage of this dataset includes 3 class, 13 orders, 20 families, 21 genus and 8 species. There is a 25% classifed to the species level, 24% to kingdom, 23% to genus, 22% to family and 6% to order.

Geographic Coverages
Anadarko Colombia Company’s hydrocarbon exploratory activities in the Southwestern Colombian Caribbean, include four wells (i.e. Gorgon A-1, Calasu 1, Kronos 1, and Purple Angel C-1), and have other areas of interest (i.e. Chamana, Chamai, Yaduli, Cana Norte, and Cawa). The exploratory wells and areas of interest are localized in the South-western Colombian Caribbean, at depths between 375 m and 2500 m. In general, wells and areas of interest are approximately 54 to 74 o shore from the nearest point in the Caribbean coast of Colombia.
