APPENDIX 2 (6) O/C index (Wiederholm, 1980) is calculated as: the density of oligochaetes divided by the density of oligochaetes and sediment-living chironomids (not including non-sediment-living species such as Procladius sp.), expressed as a percentage. Values are depthcorrected by dividing the ratio obtained above by the sampling depth. References Armitage, P.D., Moss, D., Wright, J.F. & Furse, M.T.
