MAREMAP presentation

We present recently collected swath bathymetry from the Firth of Lorn. 553km2 of data were collected during 2012 as part of the INIS Hydro program (Ireland, Northern Ireland and Scotland Hydrographic Survey). The inshore waters covered by this survey represent a priority area for the renewable industry, for shipping, tourism and encompass a number of Special Areas of Conservation (SAC) including for rocky reef habitat. Surprisingly, given this interest, this project is the first comprehensive bathymetric survey in the area. This region of near shore continental shelf is revealed as predominantly bedrock-dominated seabed, characterised by a series of narrow, strongly fault-controlled troughs, part of the Great Glen Fault Zone complex. The region includes the Corryvreckan Whirlpool and Great Race tidal flows beneath which occur active sand waves and submarine dunes.
