The dataset was colected by whale watching companies in the Azores between 2009 and 2020 as a contribution to the long term monitoring of cetaceans. It contains the identification of the species observed, the geographic position of the observation, the life stages and its respective abundance and behavior, as well as related environmental variables (sea state, visibility). more

"MONICET is a collaborative platform to collect, organize and disseminate cetacean occurrence data and photo-identification images collected by whale watching companies in the Azores. Data were collected from 2009 to 2020 in collaboration with twelve different whale watching companies located in four different islands: São Miguel, Terceira, Pico and Faial. Data was collected and inserted in the MONICET database by qualified guides or biologists onboard and validated by the research team responsible for the MONICET platform."
