English Channel Glycymeris glycymeris increment widths

Live specimens and dead shell valves of the dog cockle (Glycymeris glycymeris) were collected from the seabed using a dredge in September 2013. The collection site was Mid-South Cornwall (49° 50.821'N, 03° 11.93'W) at depths of 70-71 m. A total of 29 shells were collected, of which four were live specimens used to anchor the chronology in time.After obtaining the increment-width measurements from each shell, the age-related trend was removed by fitting a negative exponential curve to the power-transformed data and the resulting record was prewhitened retaining environmental correlation using the software ARSTAN.
