Drilling and sampling of the harbour silts and rock head interface were carried out using 98/89 mm steel casing and a Rambo 85 recovery tool. Silts were recovered in 1m plastic liners complete with "tulip" catcher for the retention of soft silts. Drilling Techniques: Diamond drilling & rotary coring in soft & hard ground.
