Values are means with SE across replicates for each turbidity level taken at test initiation T0 and test termination T24. Abbreviations: DO, dissolved oxygen; NTU, nephelometric turbidity unit; PSU, practical salinity unit; Spec. Con., specific conductance; T0, time point at test start; T24, time point at test termination.
