Measurements of underwater conductor hammering noise: compliance with the German UBA limit and relevance to the harbour porpoise (Phocoena phocoena) (PDF)

Cetaceans (whales, dolphins and porpoises) rely heavily on sound for communication, foraging, predator avoidance, orientation, and navigation. Noise generated by offshore construction work, such as piling during wind-farm construction and conductor hammering during exploration-drilling operations, has the potential to cause behavioural changes, masking of communication signals or, in extreme cases, a temporary loss of hearing […]

Rigs-to-reefs and porpoises: Précis of evidence to support leaving offshore installations in situ at the end of the operational lifetimes (PDF)

Condensed highlights from a decade of Marine Mammal Observer (MMO) and Passive Acoustic Monitoring (PAM) projects carried out from stationary and on-tow Oil & Gas (O&G) exploration jack-up drilling-rigs and production platforms is presented. The majority of work was undertaken as routine monitoring and mitigation permit requirements, but a partial aim was to investigate the […]

Marine Mammal Observer and Passive Acoustic Monitoring Handbook (PDF)

Marine Mammal Observer and Passive Acoustic Monitoring Handbook is the ultimate instruction manual for mitigation measures to minimise man-made acoustical and physical disturbances to marine mammals from industrial and defence activities. Based on more than two decades of offshore experience, and a decade of supplying MMO and PAM services (commercial and scientific), the Handbook is […]

A review of impacts of marine dredging activities on marine mammals (PDF)

Marine dredging is an excavation activity carried out worldwide by many industries. Concern about the impact dredging has on marine life, including marine mammals (cetaceans, pinnipeds, and sirenians) exists, but effects are largely unknown. Through consulting available literature, this review aims to expand on existing knowledge of the direct and indirect, negative and positive impacts […]
