Changes in version 2.0

1. Updated coral-based estimates of ΔR and its uncertainty in south Florida using data from the the Marine20 radiocarbon calibration curve, published as FKRT_Coral_Based_DeltaR_Marine20.zip.

2. Produced new models of ΔR variability through time (230Th) and versus radiocarbon (14C) ages at 5-year resolution using the updated coral-based ΔR estimates, published as Modeled_Nearshore_DeltaR_vs_230Th_Marine20.zip, Modeled_Nearshore_DeltaR_vs_Conventional_14C_Marine20.zip, Modeled_OpenOcean_DeltaR_vs_230Th_Marine20.zip, and Modeled_OpenOcean_DeltaR_vs_Conventional_14C_Marine20.zip.

3. Filenames for coral-based estimates of ΔR and its uncertainty and models of ΔR variability through time (230Th) and versus radiocarbon (14C) ages at 5-year resolution based on the Marine13 radiocarbon calibration curve (published in the first version of this data release) were updated by adding "_Marine13" to the end of the filenames.
