evidence: Carlingford Lough is a glacial fjord or sea lough that forms part of the border between the United Kingdom and the Republic of Ireland. On its northern shore is County Down (United Kingdom) and on its southern shore is County Louth (Irish Republic). At its extreme interior angle (the northwest corner) it is fed by the Newry River and the Newry Canal. [...] The Carlingford Lough Ramsar site (wetlands of international importance designated under the Ramsar Convention), is 2,052.23 acres in area, at Latitude 54° 03' 00" N and Longitude 06° 07' 00" W. It was designated a Ramsar site on 9 March 1998. It is a cross-border site. The northern shore is in Northern Ireland and includes the most significant mudflats in the lough, and an area of salt marsh. The southern shore is in the republic of Ireland. At the mouth of the lough are several small rock and shingle islands which are of importance to terns.[4] [...] - ↑ 5.0 5.1 "Carlingford Lough Ramsar site".
