Estimates of Collision Risk of Harbour Porpoises and Marine Renewable Energy Devices at Sites of High Tidal-Stream Energy

The aim of this study was to investigate how often porpoises occurred in two areas of immediate interest for tidal-stream development on the west coast of Scotland. These two sites were the tidal narrows of the Sound of Islay (between the islands of Islay


Footnotes

1. A third minke whale was sighted opportunistically during an acoustics-only transect through Area 1 (see Figure. 3B), but was not considered during subsequent analyses.

2. Note: A second run of drifters was performed in 2011 and provided much more spatial resolution on porpoise occurrence - see Appendix 2. Because this survey was funded using other resources the results were not included in the main body of this report.
