Table 7. Product-moment correlations in sediment for West Coast reference and nonurban sites. Correlations of log₁₀ element concentrations for all reference and nonurban sites. Sites include Bodega Bay, Channel Islands, Dana Point, Estero Bay, Farallon Islands, and San Luis Obispo. Number of measurements between 24 and 38 for stations over all years for each element. Bold entries are significant at alpha = 0.00033.
