The CETUS dataset contains effort-based occurrence records collected during a cetacean monitoring programme in the Eastern North Atlantic, since 2012. more

The CETUS dataset contains data collected within the CETUS Project (, a cetacean monitoring programme in the Eastern North Atlantic, running since 2012. The project is led by the Interdisciplinary Centre of Marine and Environmental Research (CIIMAR - University of Porto, Portugal), in partnership with TRANSINSULAR - Grupo ETE, a Portuguese company for maritime transport, that offers its cargo ships to be used as a platforms of opportunity to monitor cetaceans along routes between Continental Portugal and Madeira, Azores, Canary and Cape Verde islands. On-board trained marine mammal observers collect data on: survey effort, cetacean and other megafauna occurrences, as well as marine traffic and meteorological conditions. Data is provided in the recent OBIS-ENV-DATA format, and comprises 8913 georeferenced positions associated with 3195 occurrences of 44 marine taxa.
