description |
A primary objective of Ocean Drilling Program Leg 177 was to document changes in circulation and biogeochemical cycling on glacial/interglacial time scales across a wide latitudinal range of the south Atlantic Ocean. One of the more northerly sites drilled, Site 1089 (41°S, 10°E), is located within the present-day Subantarctic Zone, south of the Subtropical Front. The drilling site itself is located in the southern Cape Basin at a water depth of 4620 m. Pleistocene sediments at this site are dominated by interbedded carbonate and opal oozes. Initial shipboard stratigraphy identified the opal-rich sediments as deposited during glacial intervals and the carbonate-rich sediments as deposited during interglacial intervals (Gersonde, Hodell, Blum, et al., 1999, doi:10.2973/odp.proc.ir.177.1999). Postcruise isotopic stratigraphy, however, verified that this site displayed a Pacific Pleistocene sedimentation pattern with glacial intervals marked by high carbonate content (Hodell and Charles, 1999). To assess changes in biological productivity and terrigenous inputs at this site, a number of geochemical indicators were determined. Phosphorus concentrations and P/metal ratios were determined to assess changes in export production on glacial/interglacial time scales. Metal concentrations, along with elemental ratios, were used to assess terrigenous inputs. Sediment geochemistry allows us to identify changes in the lithologic component using elemental data based on Fe, Al, and Ti concentrations. Records of concentrations and ratios of biologically related elements identify changes in export production. The P and metal results are important to assess the glacial/interglacial changes in P burial and the relationships between a major nutrient such as P with metals (and possibly trace nutrients) like Fe. |
