Notes: Detection limit = 0.01 µL seawater/g sediment, BD = below detection. The potential for microbial contamination is based on 5 x 108 cells/L surface seawater. This may be viewed as an upper limit for microbial contamination because it requires the sediment be porous enough to allow all of the contaminating cells to travel with the PFT. HTEW = high temperature (thermophile) enrichments whole-round core.
