T–S relations of sea waters based on Argo profiles between 4° N and 6° N within 5° of longitude from 150° E in the western basin (a), and between 6° N and 8° N within 5° from 165° W and from 130° W in the central (b) and the eastern (c) basins. CTD station profiles at 8° N, 127° E and 0.45° S, 133.5° E representing the intermediate waters of the MC and NGCUC are overlapped in (a) to represent the typical water masses from the North and South Pacific. Salinity distributions (thin black contours with color shading) in meridional sections of 150° E (d), 165° W (e), and 130° W (f). In (d–f), the NESC cores are marked by the westward mean geostrophic velocity contours (white) at the interval of 1.0 cm s−1 and the density surfaces are plotted as thick grey contours. Units of the potential temperature, salinity, and potential density are degree Celsius, psu, and kg m−3, respectively. Salinity maxima of the North Pacific Tropical Water (NPTW) and South Pacific Tropical Water (SPTW), and salinity minima of the North Pacific Intermediate Water (NPIW) and the Antarctic Intermediate Water (AAIW) are marked in the panels (d–f). (a–c) is generented by Ocean Data View software version 5.1.0 (https://odv.awi.de/). (d–f) is generented by MATLAB software version R2019b (https://www.mathworks.com/).
