Variations in absolute abundance (individuals/g) of total radiolarians (a) and 13 species and species groups (b–n) for 153 samples newly examined in this study (solid lines with dots). Relative abundances (percent) of the total assemblage for each species are also shown as pale bold lines. Reddish brown (b–g), green (h–j) and blue (k) indicate groups related to the Kuroshio water, mixed water and coastal Oyashio water, respectively. Deep-dwelling radiolarians are shown as black lines (l–n). The Tr curves (red lines) are overlapped in panels (a) and (k). Intervals of the total radiolarian maxima are shown as yellow vertical bands
