Corr., correlation coefficients; the top 3 combinations are given. Chla, chlorophyll-a (μg/g); Pha, phaeophytin-a (μg/g); TOC, total organic carbon (%); T, the temperature of the surface sediments in intertidal zone and the bottom water temperature on the continental shelves and deep-sea plains (°C); MGS, median grain size (μm); WC, water content (%). The temperature and salinity of North Pacific was represented by the data of one site (160°E, 35°N, water depth 4,330 m).
