Those underwater archaeological objects were originally buried in underwater environments, which have resulted in serious damage. To conserve these objects, it is essential to fully understand the burial process and the mechanisms of damage formation and corrosion resulting from interaction between them and their surrounding environment. This research attempts to describe the marine underwater burial environment in terms of seawater, marine organisms and sediment. The paper also briefly lists and discusses China’s most commonlyseen types and causes of damage to ceramics, stone, metal and wooden artifacts.
