Abstract
Marine renewable energy (MRE) developments often coincide with sites
frequented by small cetaceans. To understand habitat use and assess
potential impact from development, echolocation clicks were recorded with
acoustic click loggers (C-PODs) in Swansea Bay, Wales (UK). General
Additive Models (GAMs) were applied to assess the effects of covariates
including month, hour, tidal range and temperature. Analysis of inter-click
intervals allowed the identification of potential foraging events as well
as patterns of presence and absence. Data revealed year-round presence of
porpoise, with distinct seasonal and diel patterns. Occasional acoustic
encounters of dolphins were also recorded. This study provides further
evidence of the need for assessing temporal trends in cetacean presence and
habitat use in areas considered for development. These findings could
assist MRE companies to monitor and mitigate against disturbance from
construction, operation and decommissioning activities by avoiding times
when porpoise presence and foraging activity is highest in the area.
