Carbonate record of ODP Leg 167 sites
Listed in PANGAEA
One of the expected scientific results of Ocean Drilling Program Leg 167 was to reconstruct the Neogene history of biogenic calcium carbonate accumulation in the northeastern Pacific along the California margin (Lyle, Koizumi, Richter, et al., 1997).
Description
This aims to constrain inorganic carbon burial rates, deep-water hydrography in the North Pacific, and linkages between deep Atlantic and Pacific circulation and carbonate accumulation or dissolution patterns.
Data are presented for four sites. Two of them are located in the California bight-East Cortez Basin (Site 1012: 32°16.970?N 118°23.024?W, 1773 m) and San Nicholas Basin (Site 1013: 32°48.040??, 118°53.992?W, 1564 m). The others are the dedicated Hole 1017E at Site 1017 (34°32.099?N, 121°6.430?W, 955 m) and Site 1019 in the Eel River Basin (41¢X40.972?N, 124°55.975?W, 977 m).

Reconstruction of paleo-sea-surface temperatures (SST) by determining the alkenone unsaturation index of the extractable organic matter is an independent technique and helps to verify oxygen-isotope-based estimates. Results from the uppermost 600 cm of the dedicated Hole 1017E are expected to reveal the local temperature history of the last 30 k.y.
