What happened to the dead in the wreck of the Estonia? Would there still be remains to be found, or would they have already completely disappeared, as in the wreck of the Titanic?

dissolved? The conditions where the Estionia lies (water pressure, salinity, water temperature/currents/fish life) are completely different than where the Titanic lies.

Could it be that the bow hatch of the Estionia was deliberately opened at full speed during a storm in order to prevent a truck with explosive cargo from entering?

Baltic Sea so that this smuggling was not discovered and the ship sank because this went wrong and the vehicle deck immediately flooded?
