Tracing recovery from acidification - a multivariate approach (ICP Waters report 69/2002)
Halvorsen, G.; Heegaard, E.; Raddum, G. (NIVA-rapport;4564, Research report, 2002-09)This report presents a method based on use of multivariate statistics to detect trends in aqutic biota as a results of chemical recovery from acidification. Three datasets from Norway, Sweden and UK are used in the work. ...
