Off the coast of Estonia, near Hiiumaa island, lie the wrecks of German warships from 1916, posing a significant ecological threat.
What happened
In November 1916, German torpedo boats S57, V72, and V75 sank after entering a minefield during a failed attack on the port of Paldiski. The ships were carrying thousands of liters of heavy fuel oil, which remains inside their hulls to this day.
A recent study by researchers from the Estonian Maritime Museum and Finland assessed the wrecks and the environmental threat they pose. The study found that while the wrecks are not currently leaking, the metal corrosion on the seabed could lead to a potential oil spill in the future.
The Baltic Sea's unique conditions, including cold, low-salinity, and oxygen-poor water, have helped preserve the wrecks and slow the breakdown of any fuel released. However, researchers warn that the threat should be addressed before the wrecks deteriorate further and the oil spills into coastal waters, potentially causing a major environmental disaster.
