Without conservation most artifacts will perish and important historic data will be lost.〔Hamilton, D. (1996). Introduction and Overview of Conservation in Archeology. In Basic methods of conserving underwater archaeological material culture (pp. 1-7). Washington, D.C.: U.S. Dept. of Defense, Legacy Resource Management Program.〕 In archaeological terms, it is usually the responsibility of archeologist and conservator to see that material recovered from a shipwreck is properly cared for. The conservation phase is often time consuming and expensive, sometimes costing more than the original excavation. One of the most important considerations when planning or implementing any action that will result in the recovery of material from a shipwreck of any marine archaeological site. ==Background== Artifacts recovered from the sea, a saltwater environment, are often preserved but fragile and friable by nature. Once the artifacts are brought to surface, and exposed to air and light, the artifacts will degrade rapidly.〔Martin, C. (n.d.). An Introduction to Marine Archaeology. Retrieved from: http://www.bbc.co.uk/history/ancient/archaeology/marine_01.shtml#four〕 Artifacts that are not conserved in timely manner will deteriorate at a rapid rate. Organic material, such as wood, leather, textiles, etc.,. if allowed to dry without conservation treatment, can in a matter of hours deteriorate and crumble. Other materials such as bone, glass, pottery, and similar materials, if not conserved, will slowly (devitrify ) and in extreme cases will degenerate to a pile of (slivers ).〔 Conservation must be part of any archaeological project, especially for underwater archeological sites. Artifacts found in salt water has the greatest challenge to a conservator. Artifacts from a saltwater environment are saturated with salt that must be removed when the artifacts are recovered.〔Hamilton, D. (1996). Basic Conservation Procedure. In Basic Methods of Conserving Underwater Archaeological Material Culture (pp. 8-11).
