<br/><br/> Current research methods for studying dolphins rely heavily on boat-based surveys using photographic identification (photo-ID) of individual’s unique features such as scarring and marks on dorsal	fins.	By building up	a sightings history of individuals, we can apply mark-recapture statistical methods to investigate ranging patterns, survivorship, and population	abundance.However, these boat-based	methods are inefficient	for small,	widely spread populations such as the Namibian coastal bottlenose dolphins which range over at least 400 km between Lüderitz and Walvis Bay. Therefore, we aim to develop a framework using biological sounds and a spatial capture-recapture approach (Borchers, 2012) to assess population density and abundance of Namibian bottlenose dolphins, contributing to long-term monitoring of this population.
