Dashed line, two-sided least-squares linear regression fit to data for the SPSG, NPSG, TP, STA, NASG and NTA (n = 6). For completeness, the mean value for PSO bins outside our eight primary regions is indicated by the white symbol. Symbols, regional mean ±s.e.m. (SISG, n = 19; SASG, n = 18; TP, n = 115; NASG, n = 16; NTA, n = 23; NPSG, n = 59; STA, n = 22; SPSG, n = 59; other, n = 302). Symbol colours identify region (labelled on the right) and correspond to the colours shown in Fig. 3a. Numbers next to each symbol indicate the median number of days with ADCP data within the 32-year field record for the 5°× 5° bins.
