Baleen Whale Vocalisations

Many baleen (mysticete) whales produce high-intensity calls, the frequency content of which resides primarily in a band below 1 kHz. Consequently, there is a reasonable probability of vocalising animals being detected on hydrophones designed to collect marine-acoustic geophysical data, such as towed and bottom-mounted seismic streamers. This represents an opportunity to collect potentially untapped data […]

Spatial Impact of Wind Farm Construction on Harbor Porpoise Detectability

To combat impacts of climate change, offshore wind farm construction is accelerating globally. Accompanying increases in construction activity have raised concerns about associated noise impacts on acoustically sensitive species, including harbor porpoises (Phocoena phocoena). This study investigated spatial impacts from the construction of ScottishPower Renewables’ East Anglia ONE (EA1) offshore wind farm (310 pin-piles), located […]

Detection of invasive fish species with passive acoustics: Discriminating between native and non-indigenous sciaenids

Invasive alien species have been rising exponentially in the last decades impacting biodiversity and ecosystem functioning. The soniferous weakfish, Cynoscion regalis, is a recent invasive sciaenid species in the Iberian Peninsula and was first reported in the Tagus estuary in 2015. There is concern about its possible impacts on native species, namely the confamiliar meagre, […]

A framework for net environmental benefit analysis-based comparative assessment of decommissioning options for anthropogenic subsea structures: a North Sea case study

Nicolette, J.J., Nelson, N.A., Rockel, M.K., Rockel, M.L., Testoff, A.N., Johnson, L.J., Williamson, L.D., and Todd, V.L.G. A framework for net environmental benefit analysis-based comparative assessment of decommissioning options for anthropogenic subsea structures: a North Sea case study. Frontiers in Marine Science. https://doi.org/10.3389/fmars.2022.1020334 Taxpayers and operators worldwide have significant current liabilities associated with decommissioning of offshore Oil & Gas (O&G) […]

Effect of a new offshore gas platform on harbor porpoise in the Dogger Bank

Offshore Oil and Gas (O&G) exploration and production has been cycling from cradle to grave for over 100 years, spanning many generations of marine fauna. Despite global occurrence of offshore infrastructure, implications of their presence for apex predators, including cetaceans, is under-studied. We analyzed data from autonomous underwater passive-echolocation-click detectors (C-PODs) deployed at an offshore […]
