Abstract

Bathymetric data were collected from May to August 2014 in the northwest channel of Inishmore Island, Ireland by the Marine Institute and Geological Survey of Ireland as part of the INFOMAR Project. The vessel used to collect this data was the R/V Celtic Voyager, with a Kongsberg EM2040, and 2D and 3D bathymetric and backscatter surfaces were created using CARIS HIPS and SIPS 9.1. During the Carboniferous Period (359-299 Ma) a shallow sea formed causing the formation of the Aran Islands and nearby Burren. The shallow, warm tropical seas allowed for the deposition of biogenic carbonate sediments which would eventually form limestone. This study site has since been greatly affected by tectonic uplift, sea level rise and fall and glacial action. The submarine glacio-karst features were examined to help understand the relationship of the study site to the adjacent terrestrial areas.
