Project Description

Funding Body: INTERREG IIIA, NPWS, Marine Institute, and Heritage Council

Programme: FP6
Project type: PhD – post-doc (in transition!!)
Period: 2003 – 2006 (INTERREG IIIA), 2006 – 2007 (NPWS and MI)

This project considered the spatial relationship of leatherback turtles and their jellyfish prey in the Irish Sea. Key elements of the project include aerial surveys of the Irish Sea, satellite tracking of leatherback turtles, shoreline jellyfish surveys, schools workshops and public seminars. Through collaboration with existing conservation bodies we tackled the long unanswered question of whether leatherbacks are merely oceanic wanderers that find themselves in our waters or whether they form an important part of our natural heritage. The continued success of this project was made possible thanks to the generous funding received from National Parks and Wildlife Service of the Department of Environment, Heritage and Local Government Ireland and the Marine Institute Ireland, and is part of an ongoing collaboration between University College Cork and University of Wales Swansea .
