The Post-glacial marine transgression in N. Ireland-Conclustion from Esturine and raised beach deposits: A contrast

Studies of the raised beaches in Co. Down have suggested a water level of + 30 ft. (9.2 m.) I.O.D. in the Atlantic period (c. 8,000-5,000 B.P.).
Stratigraphical, palynological and radiocarbon investigations of estuarine deposits in Co. Down indicate that the maximum of the post-glacial relative sea-level rise was shortly before 3,000 B.P. when high-water reached to 12 ft. (c. 3.6 m.) above present mean sea-level. The regression since the maximum is apparently of the order of 4 ft. (c. 1.2 m.). These findings stand in contrast to earlier tentative conclusions from open coast 'raised beach' studies that the sea rose at its maximum to c. 22 ft. (6.46 m.) above mean sea-level before 5,000 B.P.
