Waterlogged wood is a wooden object that has been submerged or partially submerged in water and has affected the original intended purpose or look of the object. . Waterlogged wood objects can also include wood found within moist soil from archaeological sites, underwater archaeology, maritime debris, or damaged w
The major archaeological problem with waterlogged finds, particularly wood, is that they deteriorate rapidly when they are uncovered, beginning to dry and crack almost at once. They therefore need to be kept wet until treated in a laboratory. Conservation measures explain why wet archaeology costs around four times as much as dry archaeology.
As a result, marine waterlogged archaeological wood preserved in museums becomes more sensitive to changes in humidity,” researchers from Beijing and Quanzhou said in a separate study published ...
Archaeological Waterlogged normally looks well preserved; however, it is very weak and deteriorates because of the soluble water substance making it dissolve in marine environments. [8] The cellulose of the wood goes through the process of hydrolysis and attacked by anaerobic bacteria that decompose the wood, leaving it only with the lignin ...
Underwater logs are safe from many of the forces which cause decomposition, including fungi. Log salvage operations began in the early 20th century across the United States. John Cayford and Ronald Scott's book Underwater Logging describes the process and prospects for retrieving sunken wood from American waterways, known as salvage logging. [4]
The five common chemical agents that damage wood are: Light – Creates a chemical reaction within the cell walls of wood, leading to a change in color or texture; Acids – Cause wood to become brittle. Alkalies – Cause the fibers of the wood to separate and break down. Salts – Similar to alkalies, salts break down the fibers of wood.
Waterlogged: Preservation of plant material can also occur when it is deposited in permanently wet, anoxic conditions, because the absence of oxygen prohibits microbial activity. This mode of preservation can occur in deep archaeological features, such as wells, and in lakebed or riverbed sediments adjacent to settlements.
