Data collected on multi-channel hydrophone arrays to determine 3D locations of cetaceans off the Holyhead coast. Two passive acoustic monitoring (PAM) approaches have been developed for measuring the underwater behaviour of porpoises and dolphins using passive acoustic localisation. One approach was designed to collect behavioural data over large spatial areas and the other can be targeted at specific locations. Access to the MCRP data is strictly subject to the MCRP Data Terms of Use. Please ensure that you read and understand the Terms of Use prior to using any of the data as you will be bound to comply with the same. The MCRP Terms of Use are the prevailing Terms of Use and supersede that of Marine Data Exchange Terms of Use in relation to MCRP data. https://www.marinedataexchange.co.uk/content/info/terms-of-use otherRestrictions Once published, there will be no constraints on access and use.

In some instances, this compliance will not be feasible. True Commission Regulation (EU) No 1089/2010 of 23 November 2010 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards interoperability of spatial data sets and services 2010-12-08T00:00:00 publication Conformity with the Commission Regulation (EU) No 1089/2010 was either not relevant to this dataset or not a requirement of the Marine Data Exchange for the creation and submission of this dataset ; therefore, conformity has not been assessed and cannot be declared True series These data consist of high frequency raw acoustic recordings collected on hydrophone arrays to localize the underwater location of dolphins and porpoises. Hydrophone arrays consist of multiple dispersed hydrophones. Two types of hydrophone array were used to collect data, a drifting vertical array and bottom mounted arrays. This dataset has been collected by the University of St Andrews as part of the The Marine Characterisation Research Project (MCRP) which forms part of the Morlais tidal energy project, managed by Menter Môn and funded by the European Regional Development Fund and The Crown Estate. The Marine Characterisation Research Project (MCRP) is an innovative research and development project that will ensure the safe phased deployment of tidal energy turbines in the Morlais Demonstration Zone.
