ClamAge

Count and measure growth rings in bivalve shell cross-sections

Scientific AIFree

ClamAge automates growth increment counting and measurement in bivalve shell cross-section images for sclerochronological age determination. The tool traces the acetate peel or thin section growth line pattern using edge detection tuned for annual, tidal, and daily increment scales in species including Arctica islandica, Mercenaria, and geoduck. Growth rate chronologies from increment width time series serve as proxies for marine environmental reconstruction spanning centuries to millennia.
