This report provides an overview of all the relevant data concerning methane-derived authigenic carbonate (MDAC) and other features associated with shallow gas and seabed fluid flow in the Irish sector of the western Irish Sea. The report complements the MDAC report produced for the SEA6 area by Dr A. G. Judd.

The report makes use of some previously published data, but mainly analyses the datasets held by the Petroleum Affairs Division of the Irish Department of Communications, Marine and Natural Resources. Over the last 40 years the IRL-SEA6 area has been surveyed with a range of remote sensing and ground-truthing techniques providing information at various scales of resolution. The main driving factors for these investigations were exploration for hydrocarbons in the Kish Bank and the Central Irish Sea basins, as well as cable and pipeline route surveys. The existing data includes the following: seismic data including conventional seismic and high-resolution seismic (e.g. Sparker, Boomer, GeoChirp, etc.); echosounder; side-scan sonar and multibeam coverage over certain areas; video and photographic imagery of selected parts of the seabed, located based on remotely sensed data; and seabed samples collected with various techniques (e.g. Gravity cores, dredge samples etc.).
