Abstract

14C dates from core PC1 collected from T Lake, Palau in September 2013 using a Colinvaux‐Vohnout Livingstone‐type rod‐operated piston corer.

Sediment core PTLN‐PC1 was collected September 2013 in sequential 1‐m sections using a 5‐cm‐diameter Colinvaux‐Vohnout Livingstone‐type rod‐operated piston corer (Geocore, Columbus, Ohio). Each section was sealed in the field and refrigerated at 4 °C until core splitting and subsampling.

Thirteen macrofossils were pulled from the core and were pretreated with an acid‐base‐acid procedure according to the protocol in Brock et al. (2010) to remove extraneous organic materials. Accelerator mass spectrometry 14C dating was performed by DirectAMS in Bothell, WA, United States.
