Aberystwyth to Skomer subtidal lifeforms map
Description
This is the final report on sublittoral mapping of Milford Haven, Pembrokeshire and south Cardigan Bay which formed part of the Broadscale Mapping Project: a project funded by the Crown Estate, the Countryside Council for Wales, English Nature, Scottish Natural Heritage and the Newcastle University (SeaMap). It is supported by the European Commission under the Life programme. The survey of the Milford Haven, Pembrokeshire and south Cardigan Bay has contributed to the development of a methodology for broad scale survey and mapping of large areas of sea floor using acoustic remote sensing techniques. The methodology relies on the relatively inexpensive acoustic ground discrimination system (AGDS) based on a single beam echo sounder. Image processing requires ground truth samples of the biota and habitats from the sea floor and the sampling techniques range from the traditional grab, trawl and dredge to the deployment of remote video.
