The framework agreement involves the assignment of establishing monitoring points of preservation conditions for archeological deposits from the Middle Ages through continuous logging of selected parameters. Some assignments are MOV level 2, which only involves extraction and analysis of samples. Often samples from profile, excavation or drilling point will be taken out by the archaeologist also delivered for analysis. Other assignments are MOV level 3, i.e. both sample taking, analyzing and installing environment monitoring equipment at selected locations in and outside the Medieval Norwegian towns. The preservation condition (MOV level 1) is documented by NIKU at the same time that samples are extracted for analysis and any equipment is assembled by the supplier.
