Abstract:
Vibracores (7.5 cm diameter) were collected from Drinkwater Sinkhole in the Northern Bahamas using a Rossfelder-P3 submersible vibracoring system in December 2018. The recovered cores sampled the upper ~15.5 m of the preserved stratigraphic succession of the lake bed. After collection, cores were sectioned into lengths (up to 150 cm long) and shipped to Texas A&M University at Galveston for lengthwise splitting in the laboratory. After sectioning, cores (C11-D1, C8-D4, C8-D3, C7-D4, C7-D5, C6-D4, C9-D3) were shipped to the International Ocean Discovery Program in College Station for linescan imaging. This dataset is the high resolution tif files for the line scan images.
