\"Proportion<\/a>Marine Scotland is currently running a world leading monitoring programme to detect the presence of dolphins and porpoises at 30 sites along the east coast of Scotland. The aim of the programme is to establish the distribution of dolphins and porpoises, providing valuable information on which to base future marine renewable developments.<\/p>\n

In May 2014, work began on the second annual deployment of moored CPODs (echolocation click detectors), which detect the presence of dolphins and porpoises.\u00a0 These are clustered in sets of three at increasing distance from shore, at 10 locations around the coast.\u00a0 One mooring out each group of three also holds a broadband acoustic logger, which records ambient noise levels, as well as dolphin whistles.\u00a0 Analysis of whistles allows identification of dolphins to species level.<\/p>\n

Last year, porpoises were detected at most sites every day, and at the Fraserburgh site, porpoises were detected for an average of 19 hours.\u00a0 However, the known aggressive interactions between dolphins and porpoises mean that porpoises were not detected as often in areas that bottlenose dolphins are known to visit.<\/p>\n

\"Proportion<\/a><\/p>\n

The data will allow assessments to be made about whether planned wind farm developments may affect the broad scale distribution of dolphins and porpoises across the east coast and the ambient noise measurements will also be used to inform Marine Strategy Framework Directive (MSFD) noise descriptors. The noise measurements are also being analysed by the National Physical Laboratory as part of a project developing underwater soundscapes.<\/p>\n

Dr Kate Brookes, the leader of this project commented: \u201cThis project is ambitious in scale; monitoring the whole east of Scotland simultaneously.\u00a0 It will provide the first broad scale data on how and when dolphins and porpoises use particular areas.\u00a0 Analyses from last year\u2019s deployments are ongoing, but show that porpoises use many areas of the east coast every day.\u00a0 They also seem to avoid areas where dolphins spend more time, presumably to avoid the well documented aggressive interactions seen between the two species.\u201d<\/div>\n
