Behavioural and Acoustical Responses of Coastal Dolphins to Noisy Environments
MetadataShow full item record
This thesis aimed to examine the behavioural and acoustical responses of coastal dolphins to noisy environments. A combination of monitoring techniques were employed, in the form of land-based theodolite-tracking and autonomous underwater acoustic recorders. First, the soundscape of dolphin habitats was described to identify prominent sound sources and spatio-temporal patterns. Dolphin responses to the most ubiquitous anthropogenic sound source – vessel traffic – were then assessed, revealing alterations to movement speeds, behavioural budgets, and whistle characteristics.

Atypical residency of short-beaked common dolphins (Delphinus delphis) to a shallow, urbanised embayment in south-eastern AustraliaMason, S.; Salgado Kent, Chandra; Donnelly, D.; Weir, J.; Bilgmann, K. (2016)Short-beaked common dolphins (Delphinus delphis) are typically considered highly mobile, offshore delphinids. This study assessed the residency of a small community of short-beaked common dolphins in the shallow, urbanized ...
Spatial and temporal variation in the acoustic habitat of bottlenose dolphins (Tursiops aduncus) within a highly urbanized estuaryMarley, S.; Erbe, Christine; Salgado Kent, C.; Parsons, Miles; Parnum, Iain (2017)© 2017 Marley, Erbe, Salgado Kent, Parsons and Parnum. There is growing awareness of underwater noise in a variety of marine habitats, and how such noise may adversely affect marine species. This is of particular concern ...
