Abstract
AbstractWe present the first direct assessment of marine reservoir effects in the Moreton Bay region using radiocarbon dating of known‐age, pre‐AD 1950, shell samples from the east coast of Stradbroke Island and archaeological shell/charcoal pairs from Peel Island in Moreton Bay. The resulting ΔR value of 9±19 14C years for the open ocean conforms to regional values established for northeast Australia of 12±10 14C years. Negative ΔR values of −65±61 14C years and −216±94 14C years for southern Moreton Bay highlight the potential for larger offsets over the last ∼900 years. These may be linked to changing terrestrial inputs and local circulation patterns.
