Abstract
The geological significance of seismic reflectors within large sediment deposits of the Gerlache Strait
(Schollaert Drift) and the mouth of Andvord Bay (Andvord Drift) has been examined using synthetic seismograms. The
seismograms generated from the physical properties in jumbo piston cores taken at each of these drifts (28JPC and
18JPC respectively) show good agreement with the field seismic profiles when core disturbance is taken into
consideration. Both cores suggest an under-sampling of up to 30% (or compaction) during coring. This leads to
inaccuracy in the evaluation of past sedimentation rates and thus interpretations on these rates may be biased.
