Artefacts from long submerged wrecks will be saturated

Explain that artefacts from long submerged wrecks will be saturated with dissolved chlorides and sulfates


  • Seawater contains approximately 3% dissolved salts.
  • Chloride and sulfate are the most abundant anions in seawater.
  • Artefact: A human-produced object, especially one of cultural or archaeological significance.
  • The pores of artefacts from long submerged wrecks become impregnated with seawater containing chlorides and sulfates.
  • Porous materials, such as leather and wood, become very saturated with chlorides and sulfates.
