Northern Ireland has a close connection with the sea. We have over 650 kilometres of coastline and the sea is home to an amazing variety of marine life, some of which are found nowhere else in the world.
The marine environment of Northern Ireland is important for a variety of reasons. Marine life in the seas surrounding Northern Ireland is rich and varied and includes marine mammals such as harbour seals, whales and dolphins, seabirds, waterfowl and other species that migrate here such as salmon and eels (both of which are endangered). The majority of the sea life however, largely remains unseen and includes animals such as sponges, corals, sea squirts, octopus etc.
Northern Ireland is geographically situated in a unique biological location; with both cold water arctic boreal and southern lusitanian species. We are the junction between these significant water bodies and they appearance and disappearance of species may indicate climate change.
We are responsible for designating and protecting marine sites at both International and National level. We do this by monitoring the condition of the designated sites and identifying damaging activities. We also respond to consultations on activities which may impact these sites and advise on appropriate mitigation to ensure the continued ecological sustainable use of the marine environment. Our area of responsibility extends from the high water mark out to 12 nautical miles.
We work in partnership with the Ulster Museum to monitor the state and condition of our marine biodiversity through a scientific dive survey programme using technology such as high definition digital video, Remotely Operated Vehicles (ROVs), extended range diving techniques and GPS navigation systems.
You can find out more on what we do by studying our published research and monitoring reports or looking at presentations we have given in the past. You can also check out some of our videos and photographs of our local fantastic marine biodiversity.
