Developing constraints on the relative sea-level curve for the northeast of Ireland from the mid-Holocene to the present day.
Tide-gauge records from the north of Ireland have been digitized to generate annual estimates of both mean-sea-level (MSL) position from Malin Head (1958-1998), and mean tidal level (MTL) from Belfast Harbour (1918-2002). Both sites exhibit substantial annual variation, but show overall long-term shallow rates of falling relative sea-level change (RSLC) that are very similar at -0.2 mma(-1) (+/-0.37 mma(-1)) for Belfast and -0.16 mma(-1) (+/-0.17 mma(-1)) for Malin. Using these rates as constraints, plus other constraints of inferred RSLC rates from the mid-Holocene, an approximation of the likely profile of RSLC rates for the northeast of Ireland since 6 ka ago is presented.
