Well, a close look at the currents below surface will tell that it would be almost negligible for most of the heavy parts sinking right after impact (see, for example, this SHOM study about this spot hydrography available on the BEA site).
Consequently, the wreckage field should be pretty close from the actual crash site. Most wreckage would sink immediately with very little drift and only some of the parts with any remaining buoyancy would drift further away on the surface before sinking when its buoyancy will become negative.
