Spatial Assessment of a Biocriteria Applied to Texas Tidal Streams

Table 2

Field parameters by tidal stream. Color coding of studies follows Figure 1. Temperature (Temp.) in °C, Dissolved Oxygen (D.O.) in mg/L, Specific Conductance (Specific Cond.) in μmhos/cm, Salinity in PSU, Secchi depth in m. Data are means, standard deviations in parenthesis. See text for individual stream sample sizes. Dashed lines (—) indicate parameter not measured.
