Meteorological Organisation NDP Marine RTDI Desk Study Series REFERENCE: DK/01/007 Acknowledgements A study of this scope could not have been completed without the co-operation of a large number of organisations and individuals, both in Ireland and overseas. We thank the consultees, listed in Appendix 1, and in addition those who attended the Stakeholders’ Workshop for their time and constructive advice. The rapporteurs at the Stakeholders’ Workshop, Dr Francis O’Beirn and Capt. Kieran O’Higgins are acknowledged for their succinct summary of the outcome of two breakout sessions. We thank all those organisations and individuals who have given us permission to publish images and diagrams in this report. We are grateful to the Tenix LADS Corporation for their assistance in providing a survey strategy and associated indicative costs for airborne LIDAR mapping. A special acknowledgement needs to be given to the staff of the Marine Institute and the Geological Survey of Ireland who contributed professional advice and assistance. We would particularly like to thank Yvonne Shields (Marine Institute) for co-ordinating the constructive comments received in drafting this report. Drs Dick Pickrill and Brian Todd of the Geological Survey of Canada provided invaluable advice on their experience of inshore mapping. Dr Matthew Service of Department of Agriculture and Rural Development, Northern Ireland provided a welcome perspective on inshore mapping in Northern Ireland. We appreciate the advice and support of Dr Anthony Grehan of the Department of Earth and Ocean Sciences at NUI, Galway. Finally, we extend our appreciation to Jenny O’Leary of the Marine Institute who organised the Stakeholders’ Workshop and facilitated effective communication amongst the many contributors to the process that has resulted in this report. 4 NDP Marine RTDI Desk Study Series REFERENCE: DK/01/007 1.0 INTRODUCTION 1.0 Introduction 5 1.1 Context In 1999 the Irish Government allocated – €27 million to survey all of Ireland’s territorial waters. The National Seabed Survey involves the acquisition and processing of – 850,000 km2 of multibeam sonar swath bathymetry, sub-bottom seismic reflection, gravity, magnetic and ancillary geological and water column data in water depths of 50m to 4000m. The area is divided into Zone 3 (water depths 200m to 4000m), Zone 2 (50m to 200m) and Zone 1 (0m to 50m)1. By 2003, the Geological Survey of Ireland (GSI) had completed Zone 3 data acquisition and the Marine Institute had mapped a large area offshore northwest Ireland (especially Donegal Bay) as part of its Zone 2 responsibilities (Fig. 1.1). Mapping in Zone 2 will continue until 2006, by which time Ireland will be in possession of one of the most comprehensive seabed data sets in oceanic waters. Figure 1.1: National seabed survey zones.

Zone 1 was not part of the initial funding allocation for the Seabed Survey. NDP Marine RTDI Desk Study Series REFERENCE: DK/01/007 1.0 INTRODUCTION During the planning of the National Seabed Survey, it was obvious that the mapping requirements for Zone 1 (0m to 50m) were more complex than those in deeper waters. This was because of the technical difficulties in mapping Ireland’s variable coastline, its economic importance and the diversity of potential stakeholder interests in Zone 1 waters. As a consequence, the Geological Survey of Ireland and the Marine Institute focused on mapping Zones 3 and 2 respectively, where data could be collected easily and rapidly in spite of the large area. In the meantime, the Marine Institute commissioned this feasibility study to cost and prioritise a comprehensive mapping programme for Zone 1 as the final phase in the Government’s commitment to map Ireland’s entire offshore resource.
