Figure 8From: Spatial and temporal changes in zooplankton abundance, biovolume, and size spectra in the neighboring waters of Japan: analyses using an optical plankton counter T-S diagrams of the six groups (A, B1, B2, B3, C, and D) identified from cluster analysis on mesozooplankton biovolume size spectra (cf. Figure 5 A). In the Western North Pacific and adjacent seas from May and June to August 2011. To construct T-S diagrams, hydrographic data from 0 to 1,000Â m were applied. The numbers in parentheses indicate the number of stations belonging to each group.Back to article page
