The Pofatu Database is a resource for archaeologists. The database contains geochemical information on rock material. This is used by archaeologists to determine the source of the material. In the spring of 2020, the data contained over 7700 samples from sites in the Pacific Ocean region. The samples are from both archaeological sites and geological sites. The geological samples are used for comparison, to identify the source of the archaeological samples. In addition, information on provenience, context, analytical methods and bibliography are maintained. "The database also provides instrumental details, analytical procedures and reference standards used for calibration purposes or quality control." The open-access database is supported by research organizations from Germany, Australia, New Zealand, and the United States.
