Description

Supplementary Table 2: Drill fluid contamination testing. GC mass spectrometry measurements of concentrations of the tracers PFMD and PFMC in drilling fluid and sample materials.

Methods & Sampling

Contamination controls. Rotary coring contaminates the exteriors of core samples due to the circulation of drilling fluids (a mixture of Sepiolite and surface seawater) around the drilling bits. Extreme care was taken to remove/minimize this contamination and to not introduce new contamination during sample handling and analysis. During IODP Expedition 360, a new less volatile tracer, perfluoromethyldecalin (PFMD), was successfully tested and calibrated and thus used to quantify intrusion of drilling fluids into the interior of samples.
