Shipwreck

- temperature
The above mentioned, especially the stratification (silt/sand sediments piled up on the shipwrecks) and the damages caused by marine creatures is better described as "stratification and contamination" of shipwrecks. The stratification not only creates another challenge for marine archaeology but also a challenge to its primary state, the state that it had when it sank.
Stratification includes several different types of sand and/or silt, as well as tumulus and encrustations. In addition to these, these "sediments" are tightly linked to the type of currents, depth, and the type of water (salinity, pH, etc.), which implies any chemical reactions that would lead to affecting the hypothetical/possible main cargo (such as wine, olive oil, spices, etc.).
