Distribution of common dolphin sightings
(click to enlarge)

The Cetacean Offshore Distribution and Abundance in the European Atlantic (CODA) project estimated the abundance and investigated the habitat use of cetacean species in waters beyond the continental shelf and developed a management framework for determining safe bycatch limits for the common dolphin in this area. The results were intended primarily to inform assessments of the conservation status of all cetacean species and to help assess the impact of bycatch of common dolphin.

The project was supported by institutes and governments in France, Ireland, Spain and the UK.
