Technical Bulletin No. 0386: A Review of In-Situ and Laboratory SOD Measurement Comparisons

This technical bulletin compared the estimation of sediment oxygen demand (SOD) by laboratory and in-situ measurement methods. The comparison was important because it related directly to the selection of a measurement method during model calibration and/or verification. The objective was to explain reported differences between in-situ and laboratory SOD measurements by examining (a) the specific operating characteristics of the measurement devices, and (b) the organic and physical characteristics of the sediment itself.
