Middle and Late Holocene sea-level changes in Eastern Maine reconstructed from foraminiferal saltmarsh stratigraphy and AMS C-14 dates on basal peat
A relative sea-level history is reconstructed for Machiasport, Maine, spanning the past 6000 calendar years and combining 2 different methods. The first method establishes the long-term trend of sea-level rise by dating the base of the Holocene saltmarsh peat overlying a Pleistocene substrate. The second method uses detailed analyses of the foraminiferal stratigraphy of 2 saltmarsh peat cores to quantify fluctuations superimposed on the long-term trend. The combination of the 2 different approaches produces a high-resolution, replicable sea-level record, which takes into account the autocompaction of the peat sequence
