What is the size of the designated marine area in Ireland?

The designated marine area in Ireland is correctly approximated at about 880,000 km². This figure represents Ireland's exclusive economic zone (EEZ), which extends to 200 nautical miles from the coast. Within this area, Ireland has special rights over the exploration and use of marine resources, including fish and mineral resources, as well as activities related to marine energy production.

Understanding the significance of this area is vital in hydrographic surveying, as it involves mapping and studying the sea floor and seabed resources, which are critical for sustainable management and environmental protection. The precise measurement of a country’s marine territory can also play a role in international maritime law and resource allocation among countries.

Other figures mentioned do not accurately reflect the size of Ireland's designated marine area, which is based on international agreements and national legislation concerning maritime boundaries.
