I believe this was also discussed on another thread. One of the other factors is that the sediment deposit is near the shoe with depth of sediment tapering off the further from the shore it goes.
Subduction also occurs along shores (but not all), thus what gets subducted is more than an average thickness.
The areas where subduction is not occurring show buildup of sediments: the mississippii delta, and other flood plains types (bangladesh? amazon?)

Certainly these areas are building up in area from sediments.
I always find it humourous that creationists accuse science of being "uniforitarian" and then what they show is that their false "uniforitarian" strawman is false.
