1750 years of hydrological change in southern Australia: a bivalve oxygen isotope record from the Coorong Lagoon
Oxygen and carbon isotope ratios from A. helmsi samples from each centimetre of sediment from core C18 from The Coorong South Lagoon. Each sample is comprised of five shells of A. helmsi. Also shown is the age in years BP and years CE for each sample as determined by radiocarbon dating and age modelling. The oxygen isotope values are interpreted to reflect the balance of evaporation and inflow in this coastal lagoon.
