Table 2.
Summary of shells included in the Master Shell Growth Chronology. Excluded increments represents juvenile growth increments that were measured but not crossdated (see text for discussion). Crossdating corrections indicates how many corrections were made during the crossdating process where increments were either falsely identified or missed by the technician at first pass. *The first year in series extends before 1770 for the first two shells listed, however, these earlier years were not used for chronology construction.
