Consultancy projects involving these methods have included an analysis of diatom records from sediment cores across Scotland to assess their eutrophication status for SEPA (Bennion et al. 2004), analysis of diatoms in sediment cores from Norwegian lakes to define reference communities and the degree of ecological change for the Norwegian Institute for Water Research (Bennion et al. 2010), and most recently the combination of sediment trap and sediment core records to assess the extent to which acidified lakes in the UK uplands have recovered from the effects of acid deposition (Battarbee et al. 2014)
