Appendix C. Equatorial undercurrent (EUC) conditions at the study sites.

TABLE C1. EUC conditions at the study sites. Each row represents a separate cast. 216 total CTD profiles. Data from casts where EUC conditions didn’t occur are not shown. EUC frequencies reported in Appendix A as part of the multivariate site classification. Site abbreviations as in Fig. 4. EUC frequency was calculated as the number of casts with EUC “boundary” conditions ( < 20.0 0 C temperature, >  35.0 psu salinity) at a site divided by the total number of qualifying casts per site: RC = 8/21, RB = 7/17, DM = 18/22, BAL = 9/11, GOR = 21/25, GF = 7/18, PIN = 13/16, CHE = 15/16, LAB = 23/24, CHA = 7/18, LC = 7/10, GAR = 15/18.
