Dolphins were located on each transect. During 12 transects a total of 64 dolphin groups were encountered with 547 individuals recorded. Group sized ranged from 1-50 overall. Lone dolphins were reported on two occasions. Dolphins were located throughout the survey area with concentrations off Kilcredaun Head, Kilbaha, Leck Point in the outer estuary and Carrig buoy in the middle estuary. The purpose of the is Project was to provide a population assessment for Bottlenose dolphins in the Lower River Shannon SAC. Previous abundance estimates for bottlenose dolphins in the Lower River Shannon cSAC ranged from 114 in 2008 to 140 in 2006. The present estimate is lower but lies within the 95% Confidence Intervals for all surveys carried out to date. This suggests that, within the power of the survey technique, the population of bottlenose dolphins in the Lower River Shannon cSAC is relatively stable.

A spot height may be expressed as AOD for "above ordnance datum". Usually mean sea level (MSL) is used for the datum. Malin Ordnance Datum Derivation of vertical height or depth (in metres) In the Republic of Ireland, OD for the Ordnance Survey of Ireland is Malin Ordnance Datum: the Mean Sea Level (MSL) at Portmoor Pier, Malin Head, County Donegal, between 1960 and 1969. 5731 EPSG Projection 5731 - Malin Head height Metres Derivation of Altitude OD based on Mean Sea Level, Malin Head 1960-1969 Esri shapefile v10+ National Parks and Wildlife Service Department of Housing, Local Government and Heritage Ecological Data Manager +353-1-8882000 n/a National Parks and Wildlife Service 90 North King Street Dublin 7 D07 N7CV Ireland datadelivery@housing.gov.ie.ie https://www.npws.ie/sites/default/files/general/BDLS10.zip zip Dataset Bottlenose Dolphin Survey Lower River Shannon cSAC, 2010 dataset published on NPWS website INSPIRE Data Specification on Provide Spatial Data Theme keyword INSPIRE Data Specifications v3.0 2011-06-15 The INSPIRE Directive or INSPIRE lays down a general framework for a Spatial Data Infrastructure (SDI) for the purposes of European Community environmental policies and policies or activities which may have an impact on the environment. false 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 INSPIRE Interoperability Regulation 2010-12-08 Level of conformance with the 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 false The route of the survey vessel and position of dolphin schools encountered was recorded on a hand-held Garmin 72 GPS and tracks and waypoints downloaded using Garmin MapSource® software. All dolphin schools, defined as all dolphins within 100m radius of each other (Irvine et al., 1981), were recorded and a waypoint entered on the GPS at the start and end of a group encounter. This recorded time as well as location. Each group was approached slowly and group size recorded as the total number of individuals present. The number of adults, juveniles (sub-adults) and calves within the group were recorded. The attribute table of shapefile BDLS10_allgoups.shp has the following fields:
