Dataset Details - ObSERVE Aerial Surveys for Seabirds and Cetaceans in the Irish Atlantic Margin
Visual detections of Cetaceans made during Aerial Surveys using aircraft based visual observers, conducted by University College Cork as part of the ObSERVE Project 2015 - 2017
To assess the occurrence, distribution and abundance of seabirds, cetaceans and other marine megafauna in the Irish Atlantic Margin
Visual detections of seabirds, cetaceans and marine megafauna by obervers during line transect surveys (for cetaceans) / strip transect surveys (for seabirds) conducted from aircraft
Irish Atlantic Margin
2015 - 2017
Surveys followed standard line-transect methodology for aerial surveys. The target weather and sea conditions for aerial survey work were broadly prescribed as requiring a surface wind strength of Beaufort Force 3 or less, with good visibility (1km or more). Flying speed over the ground was 90 knots (167km/hr) at a survey altitude of 600 feet (183m) above the sea surface. Observers recorded all sightings of marine megafauna seen from the air including cetaceans, seabirds, seals, turtles, sharks and fish. Summer 2015 surveys were conducted using observers with considerable aerial survey experience. These experienced observers also trained and assessed Irish based observers who then undertook the remaining surveys.
Use of the data in any publication is prohibited until 1st May 2019. Any publication post 1st May 2019 should acknowledge the ObSERVE project partners the Department of Communications, Climate Action and Environment and the Department of Culture, Heritage and the Gaeltacht
