Bronze sculptures exposed to seawater face unique challenges due to the corrosive nature of saltwater. To preserve these artifacts, several effective conservation techniques can be employed.

1. Regular Cleaning and Desalination: Removing salt deposits is critical. Gentle rinsing with distilled water helps eliminate chlorides, while specialized desalination baths can extract deeper salts.

2. Protective Coatings: Applying microcrystalline wax or synthetic resins creates a barrier against moisture and oxygen, slowing corrosion. Innovations like silane-based coatings offer long-term protection.

3. Cathodic Protection: This electrochemical method uses sacrificial anodes to divert corrosion away from the sculpture, ideal for submerged or partially submerged pieces.

4. Environmental Control: For displayed sculptures, maintaining stable humidity (below 40%) and temperature reduces corrosion risks. Enclosed cases with silica gel can help.

5. Monitoring and Maintenance: Regular inspections using non-invasive techniques like X-ray fluorescence (XRF) detect early signs of deterioration, allowing timely intervention.

By combining these methods, conservators can significantly extend the lifespan of bronze sculptures in marine environments, ensuring their cultural and historical value endures.
