*Analytical age calculated using a radiocarbon
half-life of 5568 years and reported at one standard deviation in
radiocarbon years before 1950 CE by the National Ocean Sciences
Accelerator Mass Spectrometry (NOSAMS) Facility, Woods Hole,
Massachusetts.
§Calibrated ages in years before 1950 CE rounded to
nearest decade were calculated using OxCal (version 4.4.2, Bronk Ramsey
[2009; 2023]; 95% probability distribution) with the IntCal20
dataset of Reimer et al. (2020).
†Latitude, decimal degrees north; longitude, decimal
degrees west.
#Bivalve shell date calibrated using Marine20 dataset
(Heaton et al., 2020) with ΔR value of 311±48; a weighted mean of four
nearest ΔR values within 180 km of Palma Bay (Reimer and Reimer, 2001;
http://calib.org/marine/).
**Combined results of duplicate analyses of a single
sample ran by NOSAMS to assess impact of a combustion system problem
detected in December 2017. Because the replicated results were in good
agreement, NOSAMS recommended combining the results (Kathryn Elder,
NOSAMS, pers. comm., February 2018).
