Table T20. Differences between depths to seismic horizons and corrected depths.

Seismic horizons	Predicted intersection (mbsf)	ITT corrected depth (mbsf)	Difference (m)
Horizon 1C_1	38
Horizon 1C_2	83
Horizon 1C_3	179	182	+3
Horizon 1C_3a	261	267	+6
Base of Cenozoic	602

Notes: Predicted intersection depths were derived using high-resolution site-survey seismic data stacking velocities. Corrected depths were based on interval transit-time (ITT) data.
