    • Bivalve Shell Growth Indices, Chukchi Sea, Alaska, 1867-2015

    Metadata Updated: November 13, 2025

    This dataset contains the growth index from annual growth bands in the shells of two bivalve clam species (Astarte borealis and Liocyma fluctuosa) captured in the Chukchi Sea, Alaska. The growth index is based on a measurement of the annual growth increment width that has been detrended for age-related differences in growth.
