Comment:
Age model dates is SPCZ 14C and 210Pb dates used for BACON age models from Lac Lanutavake (cores UC1 and UC4 combined for a single age model), Lac Lalolalo (cores UC13, UC14, UC22, and UC24) on 'Uvea (Wallis and Futuna), Lake Lanoto'o on 'Upolu (Samoa), and Lake Ematul on Efate (Vanuatu).
Fossil leaves from both cores (UC1 and UC4) were used to make a single LATVK age model.
