Irish Sea


a marginal sea of the Atlantic Ocean between the islands of Great Britain on the east and Ireland on the west. It is joined to the ocean by the North Channel in the north and St. George’s Channel in the south.

The Irish Sea is on the continental shelf, which is intersected by a narrow trench that is parallel to the coast of Ireland. The maximum depth is 272 m. The bottom deposits are pebbles, sand, and coquina. Major islands are the Isle of Man and Anglesey. The shoreline is indented by small gulfs and bays. Westerly winds prevail over the sea during most of the year. Storms are frequent in winter. In winter, the air temperature is about 5°C and in summer, 15°C. The water temperature varies from 5°-9°C in February to 13°-16°C in August, changing little with depth. The salinity is from 32 to 34.8 parts per thousand. The surface currents form cyclonic circulation patterns. The tides are semidiurnal, and their heights range from 1.2 to 6 m. There is fishing (herring, sprat, cod, and anchovy). Major ports are Liverpool (in Great Britain) and Dublin (in Ireland).
