Common Sole Larvae Survive High Levels of Pile-Driving Sound in Controlled Exposure Experiments
In view of the rapid extension of offshore wind farms, there is an urgent need to improve our knowledge on possible adverse effects of underwater sound generated by pile-driving. Mortality and injuries have been observed in fish exposed to loud impulse sounds, but knowledge on the sound levels at which (sub-)lethal effects occur is limited for juvenile and adult fish, and virtually non-existent...
متن کاملRecovery of Barotrauma Injuries in Chinook Salmon, Oncorhynchus tshawytscha from Exposure to Pile Driving Sound
Juvenile Chinook salmon, Oncorhynchus tshawytscha, were exposed to simulated high intensity pile driving signals to evaluate their ability to recover from barotrauma injuries. Fish were exposed to one of two cumulative sound exposure levels for 960 pile strikes (217 or 210 dB re 1 µPa(2)·s SEL(cum); single strike sound exposure levels of 187 or 180 dB re 1 µPa(2)⋅s SEL(ss) respectively). This w...
متن کاملRecovery of Barotrauma Injuries Resulting from Exposure to Pile Driving Sound in Two Sizes of Hybrid Striped Bass
The effects of loud sounds on fishes, such as those produced during impulsive pile driving, are an increasing concern in the management of aquatic ecosystems. However, very little is known about such effects. Accordingly, a High Intensity Controlled Impedance Fluid Filled wave Tube (HICI-FT) was used to investigate the effects of sounds produced by impulsive pile driving on two size groups of h...
متن کاملIn Situ Mortality Experiments with Juvenile Sea Bass (Dicentrarchus labrax) in Relation to Impulsive Sound Levels Caused by Pile Driving of Windmill Foundations
Impact assessments of offshore wind farm installations and operations on the marine fauna are performed in many countries. Yet, only limited quantitative data on the physiological impact of impulsive sounds on (juvenile) fishes during pile driving of offshore wind farm foundations are available. Our current knowledge on fish injury and mortality due to pile driving is mainly based on laboratory...
متن کاملAutomatic Controlled Vibratory Pile Driving with Shock-stress Limitation
For several decades vibratory pile driving has been extensively applied in civil engineering, e.g. in the construction of bulkheads. On urban construction sites shock waves occur which could damage nearby building structures and annoy humans. State-of-the-art machinery provides three control inputs (frequency, excitation force and surcharge force) to achieve two almost contradictory goals: fast...
