Figure F29. Sites 1232–1235 are located at the southernmost reaches of the Peru-Chile Current system, in the transition between the subtropical and subpolar gyres. A. Contours of annual mean surface water temperatures. Arrows indicate surface water currents. ACC = Antarctic Circumpolar Current, PCC = Peru-Chile Current, PCCC = Peru-Chile Countercurrent, CFW = Chilean Fjord Water, CCC = Coastal Countercurrent. B. Salinity contours showing influx of Chilean Fjord Water (CFW). Site 1233 is best located to monitor low-salinity surface waters that advect northward, a measure of the strength or location of the westerly winds. Sites 1234 and 1235 are located to the north, within the eastern boundary current setting, in an upwelling center off of Concepción.
