Since Zone 3 mapping began in July 2000, the west coast seabed has been thoroughly investigated to reveal massive valleys, canyons and rocky outcrops. This information is of primary geological importance, while also providing a good picture of the sub-sea landscape! In addition we have also achieved a better understanding of the cold-water coral reef ecosystem which borders Ireland's continental shelf. This scientific information is vital for the sustainable management of the marine ecosystem.
Marine Environment Monitoring
During INSS cruises, the RV Celtic Explorer also carries out detailed marine environment monitoring by sampling water at different depths and by taking samples of the seabed. Data gathered is used to understand water movements, the spread of pollutants and fish behaviour in the oceans. This information facilitates habitat mapping and an understanding of how our oceans operate.
Offshore Resource Exploration
Scientists also gather information on the composition of the rock and sediments which form the seabed and underlying structures. This baseline information is of value for the future of offshore resources including fisheries, telecommunication cables, aggregate extraction, and oil and gas exploration. Accurate seabed data can also help in the planning of wind and wave power station placements around our coasts in the years ahead.
Safe Navigation
Accurate seabed maps are essential for ensuring safe navigation at sea, both commercial and leisure. The INSS is producing a comprehensive series of bathymetric (water depth) and geological maps which will be of interest to mariners, offshore energy, telecommunications companies and the tourism and leisure industry. Seabed classification maps are also produced showing the distribution of sediment type on the seabed.
Structures on the Seabed
Many ships have sunk off the coast of Ireland over the years, and Seabed Survey techniques can be used to identify the position of significant wrecks on the seafloor. To date, the INSS has delivered location data of more than 1,000 shipwrecks off our coasts.
