- Abstract
We developed predictive distribution models of deep-sea elasmobranchs for up to 2000 m depth in the Azores EEZ and neighboring seamounts, from approximately 33°N to 43°N and 20°W to 36°W. Georeferenced presence, absence, and abundance data were obtained from scientific surveys and commercial operations reporting at least one deep-sea elasmobranch capture. A 20-year 'survey dataset' (1996-2017) was compiled from annual scientific demersal surveys using two types of bottom longlines (types LLA and LLB), and an 'observer dataset' (2004-2018) from observer programs covering commercial fisheries operations using bottom longline (similar to type LLA) and vertical handline ('gorazeira').

Occurrence data: 38 fishery-independent surveys from R/V Arquipélago and on-board observer data surveys from PNRD collection, CoralFISH and Discardless/MERCES/SPONGES. Bathymetric Position Index derived from multibeam data for the Azores EEZ and bathymetry data extracted from EMODNET. To read the sources of nitrates, phosphates, silicates concentration, dissolved oxygen, % of oxygen saturation, temperature and current speed near the ocean bottom, see the Description.
