Such an understanding has hitherto been limited because the temperate marine environment has lacked an absolute timescale of the kind provided by tree-rings for the terrestrial environment and by corals for the tropical marine environment. Here we present the first annually resolved, multi-centennial (489-year), absolutely dated, shell-based marine master chronology. The chronology has been constructed by detrending and averaging annual growth increment widths in the shells of multiple specimens of the very long-lived bivalve mollusc Arctica islandica, collected from sites to the south and west of the Isle of Man in the Irish Sea. The strength of the common environmental signal expressed in the chronology is fully comparable with equivalent statistics for tree-ring chronologies. Analysis of the 14C signal in the shells shows no trend in the marine radiocarbon reservoir correction (ΔR), although it may be more variable before ∼1750. The δ13C signal shows a very significant (R2=0.456, pb0.0001) trend due to the 13C Suess effect. STUDY NOTES: These datasets include raw measurements of annual growth increments in shells of the mollusc Arctica islandica from sites close to the Isle of Man, Irish Sea; crossdated chronologies derived using mean value functions of the detrended raw measurements; delta 13C data and radiocarbon data, including the marine radiocarbon reservoir correction (delta R). All these data are used in Butler et al 2009, and the chronologies are also used in Butler et al 2010, Quaternary Science Reviews 29(2010) 1614-1632 Keywords: Sclerochronology, Irish Sea, Arctica islandica NCDC-Paleoclimatology https://www.ncdc.noaa.gov/data-access/paleoclimatology-data - Bauer Bruce Investigator : Butler, P.G.
