Table 4. Product-moment correlations in sediment for Pacific coast reference and nonurban sites. Correlations of log₁₀ element concentrations for all reference and non-urban sites, including some exploratory sites. Sites include Bodega Bay, Boca de Quadra, Chukchi Sea, Channel Islands, Dana Point, Estero Bay, Farallon Islands, Kamishak Bay, Lutak Inlet, Oliktok Point, and San Luis Obispo. Number of measurements between 39 and 57 for stations over years for each element. Bold entries are significant at alpha = 0.00033.
