Resumo

Site 1237 is located on Nazca Ridge ~140 km off the coast of Peru and thus within the offshore region of the Peru-Chile Current. A total of 83 samples were used to provide an initial radiolarian biostratigraphic framework for Site 1237; radiolarians are present to Sample 202-1237B-19H-2, 58-60 cm (186.45 meters composite depth [mcd]) and are of good to fair abundance and preservation. Site 1237 is influenced by both subtropical and northward-transported southern latitude waters, has 55 ash layers within the uppermost 166 m, and has minimal to gross reworking. Shipboard paleomagnetic results showed that the upper 200 m spanned the last 12 m.y., and in the upper 100 mcd, the paleomagnetic inclination pattern could be directly correlated to the geomagnetic polarity timescale (GPTS). Tropical biostratigraphy was used to establish the zonal boundaries for Site 1237, and the paleomagnetic and radiolarian stratigraphy were well correlated.
