Figure F98. Fraction of drilling-induced cohesive aggregates (DICAs) in the bulk >4 mm cuttings size fraction for the interval 1800–2004.5 mbsf in comparison with times when the bit was off bottom, Hole C0002F. Underreamer depths of minima in DICAs (blue arrows) seem to correlate with depths when the bit was off bottom for long times (yellow arrows).
