Figure F2. Location map (Shipboard Scientific Party, 2003) showing Sites 1237 and 1236 on Nazca Ridge and their tectonic backtrack paths, plus annual mean sea-surface temperature (SST). Note that Site 1237 was within the subtropical South Pacific gyre during the late Oligocene. Also shown are positions of the Peru-Chile Current (PCC) and the South Equatorial Current (SEC).
