Figure 6 in Inter-oceanic comparison of planktonic copepod ecology (vertical distribution, abundance, community structure, population structure and body size) between the Okhotsk Sea and Oyashio region in autumn
Figure 6. Vertical distribution of the prosome length ratios of the copepods (PLOkhotsk: PLOyashio) (left) and temperature anomalies (°C: TOkhotsk – TOyashio) (right) between the Okhotsk Sea (St. OK24) and Oyashio region (St. 19) evaluated by IONESS from October to November 1996. The vertical distribution of each copepod is calculated by daily duplicate samples in the Okhotsk Sea (symbols and bars indicate the means and standard deviations of D50%, respectively). For inter-oceanic comparison, the dashed lines in each panel indicate that the positions of values of both regions are equal.
