Use of multibeam imaging sonar for observation of marine mammals and fish on a marine renewable energy site. [PDF]

PLoS ONE, 2022
Environmental data is crucial for planning, permitting, execution and post construction monitoring of marine renewable energy projects. In harsh conditions in which marine renewable energy is harvested, integrated monitoring platforms comprising ...

Automated Detection and Tracking of Marine Mammals in the Vicinity of Tidal Turbines Using Multibeam Sonar [PDF]

Journal of Marine Science and Engineering, 2023
Understanding how marine animals behave around tidal turbines is essential if we are to quantify how individuals and populations may be affected by the installation of these devices in the coming decades. Our particular interest is in collision risk, and

Marine mammals and sonar: Dose‐response studies, the risk‐disturbance hypothesis and the role of exposure context [PDF]

Journal of Applied Ecology, 2017
Abstract Marine mammals may be negatively affected by anthropogenic noise. Behavioural response studies (BRS) aim to establish a relationship between noise exposure conditions (dose) from a potential stressor and associated behavioural responses of animals. A recent series of BRS have focused on the effects of naval sonar sounds on cetaceans.

Automated detection and tracking of marine mammals: A novel sonar tool for monitoring effects of marine industry [PDF]

Aquatic Conservation: Marine and Freshwater Ecosystems, 2019
Abstract Many marine industries may pose acute risks to marine wildlife. For example, tidal turbines have the potential to injure or kill marine mammals through collisions with turbine blades. However, the quantification of collision risk is currently limited by a lack of suitable technologies to collect long‐term data on marine mammal behaviour ...

Marine mammal mitigation through financial risk measures and probabilistic formalism of sonar exposure [PDF]

Abstract Many countries use mathematical modelling and decision aids for mitigating the risk of harm to marine mammals due to active sonar tests. A model for the distribution of harm to marine mammals due to sonar exposure is developed and risk measures from financial mathematics are used to quantify worst-case scenarios. The distribution model

Behavioural responses of common dolphins to naval sonar [PDF]

Royal Society Open Science
Despite strong interest in how noise affects marine mammals, little is known for the most abundant and commonly exposed taxa. Social delphinids occur in groups of hundreds of individuals that travel quickly, change behaviour ephemerally and are not ...

Combining real-time and historic marine mammal information for sonar risk assessment forecasting and backtesting [PDF]

Abstract Incorporating (near) real-time detection data into active sonar risk assessments has been difficult due to challenges in collecting the data and fusing multiple sensing modalities. A mixture model is developed in this work which splits marine mammals in the area into known and unknown mammals according to the detections made by sensors.
