title: CATT F-POD Data - England, Channel Islands

description: These data gathered and contributed to CATT by:Governments of Jersey, Guernsey and DolFin ID Project<i>England Channel Islands ~ Bailliwick's Spatial and Marine Plans</i>Each site has a unique Site Code of 13 characters GB 050N 005W XXX the first three characters are landmass, the next six are latitude and longitude, the last three identify the specific site.The data set contains files generated by the Chelonia Limited passive acoustic logger, F-POD. The files can be analysed using the freeware available on a link in related materials. This dataset is updated regularly with new recordings.Classification and noise risks are scored from 0 to 11 for each file using ‘Classification Warnings’ (Files & Filters Tab) Quick view or export.Summed risks of 3 or 4 require user evaluation.Summed risks of 5 or 6 likely require special handling.Summed risks of 7 and above are likely highly misleading.The CATT project aims to track trends in the population of those cetacean groups that can be monitored acoustically by logging their echo-location activity using the F-POD instrument made by Chelonia. These groups are porpoises, dolphins and all other toothed whales except the Sperm Whale.Long term population monitoring projects are notoriously difficult to establish using conventional funding streams, so CATT is supported by the participants and by Chelonia Limited. Chelonia is loaning instruments and providing free data curation, some data analysis, and funding for the deployment of F-PODs on some coastal observation sites maintained for other purposes. After 5 years it should be possible to form a clear assessment of the utility of the project and how it might best proceed.The data will become openly available within 6 months of being brought ashore, on the basis that users should notify and acknowledge the participants whose data is used.The data can support various types of analysis and opportunities that will include:Detection of trends over time in levels of cetacean acoustic activity.Insights into local patterns of cetacean activity of particular interest to participating citizen groups.Studies of cetacean acoustic behaviour – F-POD data has already given major insights intoclick-based social communication in riverine and marine dolphins, and in porpoises.Opportunities for Master’s projects and larger academic studies.Opportunities for training in relevant skills including handling and analysing the data set.Opportunities for raising awareness of ocean life.<b>Governments of Jersey, Guernsey and DolFin ID Project</b>CHI Sark CHI049N002WSRCHI COQ GB048N002WCOQCHI E_MINQS GB048N002WEMQCHI W_MINQS GB048N002WWMQCHI NOIRE GB049N001WGSECHI NOIRE GB049N001WNOICHI AMMO GB049N002WAMOCHI Burhou GB049N002WBURCHI COQ GB049N002WCQBCHI WestMinquiers GB049N002WGEWCHI W_GUERNSEY1 GB049N002WGN1CHI W_GUERNSEY2 GB049N002WGN2CHI Guernsey GB049N002WGNECHI Guernsey GB049N002WGNYCHI NE_HERM1 GB049N002WHM1CHI NE_HERM2 GB049N002WHM2CHI NOIRMONT GB049N002WJESCHI JER PLEMONT GB049N002WJNWCHI Noire GB049N002WNOICHI NOIRMONT GB049N002WNRMCHI PLEMONT GB049N002WPLMCHI S_ALDERNEY GB049N002WSALCHI W_ALDERNEY GB049N002WWAL<br>
