In July 2005 we surveyed the entire EU Atlantic continental shelf to generate robust estimates of abundance for harbour porpoise and other cetacean species. The survey used line transect sampling methods and purpose built data collection equipment designed to minimise bias in estimates of abundance. Shipboard transects covered 19,725 km in sea conditions 6Beaufort 4 in an area of 1,005,743 km2. Aerial transects covered 15,802 km in good/moderate conditions (6Beaufort 3) in an area of 364,371 km2. Thirteen cetacean species were recorded; abundance was estimated for harbour porpoise (375,358; CV = 0.197), bottlenose dolphin (16,485; CV = 0.422), white-beaked dolphin (16,536; CV = 0.303), short-beaked common dolphin (56,221; CV = 0.234) and minke whale (18,958; CV = 0.347). Abundance in 2005 was similar to that estimated in July 1994 for harbour porpoise, white-beaked dolphin and minke whale in a comparable area. However, model-based density surfaces showed a marked difference in harbour porpoise distribution between 1994 and 2005. Our results allow EU Member States to discharge their responsibilities under the Habitats Directive and inform other international organisations concerning the assessment of conservation status of cetaceans and the impact of bycatch at a large spatial scale. The lack of evidence for a change in harbour porpoise abundance in EU waters as a whole does not exclude the possibility of an impact of bycatch in some areas. Monitoring bycatch and estimation of abundance continue to be essential.Please contact data providerData from three teams aboard different airplanes were merged.

'0' values in obs_count were converted to null (no group size recorded) for all species but harbor porpoise. For harbor porpoises, '0' was replaced with '1' according to the provider's consultation. 'NA' and '99' in numeric fields in the original data were replaced with null Permissible values for date and time and coordinates were validated by the data provider and the OBIS-SEAMAP data manager. Species identification by the data provider was matched with Integrated Taxonomic Information System. Erroneous effort data that have lat/lon coordinates (39.06755, -94.897666) were removed. All observation records are included. No species records (e.g. plastic, trash) are archived in the database but not available online.Data were put through the OBIS-SEAMAP data registration steps.20140508Point 1e-051e-05Decimal degrees D_WGS_1984WGS_1984 6378137.000000298.257224 Biogeographic dataBiogeographic dataNot applicableoidUnique ID number (generated by OBIS-SEAMAP)Data providerUnique ID number (generated by OBIS-SEAMAP)ltdefinition not providedData providerdefinition not providedsighting_nSighting numberData providerSighting numbertransect_nTransect numberData providerTransect numberflight_noFlight numberData providerFlight numberobs_datetimeDate and time of observation in local time calculated by OBIS-SEAMAPData provider2005-06-27 14:38:422005-08-04 10:32:47datetime_utcDate and time of observation in UTCData provider2005-06-27 14:38:422005-08-04 10:32:47observerObserver IDData providerObserver IDdec_angleVertical angle in degreesData provider090sp_obsSpecies name recordedData providerSpecies name recordedsp_tsnTaxonomic Serial Number added by OBIS-SEAMAPData providerTaxonomic Serial Number added by OBIS-SEAMAPData providerobs_countbest estimate of number of animalsData provider1150cueRecord of the initial cue for the sightingData providerRecord of the initial cue for the sightingswim_direcSwim directionData providerSwim directionreactionReactionData providerReactiondiveDiveData providerDivedist_alongdefinition not providedData provider-754305194169perp_distPerpendicular distance to the animal sightedData provider-431477xtedefinition not providedData provider-11618420other_tmdefinition not providedData providerdefinition not providedother_xtedefinition not providedData provider00latitudeLatitude in decimal degreesData provider0.00000061.943490longitudeLongitude in decimal degreesData provider-10.7543309.899150commentsCommentsData providerCommentsorig_pod_sPod size originally recordedData providerPod size originally recordedsideSide of the airplane (L or R)Data providerSide of the airplane (L or R)behaviourBehaviorData providerBehaviorData providercalvesNumber of calvesData provider1otcomputerComputer (also identifier of the team)Data providerComputer (also identifier of the team)geomGeometry field added by OBIS-SEAMAPData providerGeometry field added by OBIS-SEAMAPThis section explains attributes included in the original dataset.
