Color version of Figure 5d, located in Figure 3. Line 78 is shown interpreted
in the published article. Line 77 is shown as black and white seismic with
color interpretation because the color amplitude did not look so good
because of low signal to noise (related to ice conditions). The free air gravity
shows a high within outer Colbeck Trough. The northern part of Colbeck Trough
affects only undeformed late Oligocene and younger strata and therefore its
position is not controlled in this area by rift structure. Vertical exaggeration
is about 7 times at the seafloor in the .pdf version of this figure.
