A diatom intercomparison exercise on sampling, slide preparation, countsand identification has been carried out in September 1999 with 24French-speaking diatomists on the River Loup (Alpes Maritimes, France). Fewoperators strictly respected the standard, especially for the number ofindividuals to be counted. It has however been demonstrated this had a very lowimpact on the index value and that old counts can be used for indexcalculation,if there are at least 300 frustules or valves. Counts… CONTINUE READING
