On clicking sounds in UK waters and a preliminary study of their possible biological origin
In recent years it has been noted that the ambient noise field in coastal waters at various sites around the southern UK contains an impulsive noise contribution. Specifically a clicking sound can be heard amongst the ambient noise, which is particularly evident at low sea states. The noise exhibits similar qualities to the snapping sound made by various species of crustacea, e.g. members of alpheus family. The range of such animals is not usually considered to include the UK, they are most commonly found in reefs in tropical regions. However, some animals have been captured during dredging operations and have also recently been photographed in UK waters.
This paper reports the results of our work exploring the acoustic aspects of this phenomenon. We shall present data recorded at various sites on the southern coast of the UK, from Cornwall in the West to Chichester in the East. These data have been collected on a variety of recording apparatus and in different recording environments. Results will be presented that detail the temporal and spectral characteristics of individual clicks. Further the results of analysis of data collected on a 3-D array will allow us to estimate source distribution through the water column.

Abstract

In recent years it has been noted that the ambient noise field in coastal waters at various sites around the southern UK contains an impulsive noise contribution. Specifically a clicking sound can be heard amongst the ambient noise, which is particularly evident at low sea states. The noise exhibits similar qualities to the snapping sound made by various species of crustacea, e.g. members of alpheus family. The range of such animals is not usually considered to include the UK, they are most commonly found in reefs in tropical regions. However, some animals have been captured during dredging operations and have also recently been photographed in UK waters.
This paper reports the results of our work exploring the acoustic aspects of this phenomenon. We shall present data recorded at various sites on the southern coast of the UK, from Cornwall in the West to Chichester in the East. These data have been collected on a variety of recording apparatus and in different recording environments. Results will be presented that detail the temporal and spectral characteristics of individual clicks. Further the results of analysis of data collected on a 3-D array will allow us to estimate source distribution through the water column.
