Abstract

Integrated Ocean Drilling Program Expedition 317 drilled progradational sequences on the continental shelf and upper slope in the offshore Canterbury Basin on the eastern margin of the South Island of New Zealand. We measured δ¹⁸O and δ¹³C values in benthic foraminifers (Nonionella flemingi) from the upper 550 meters below seafloor at slope Site U1352. The results of the oxygen isotope ratios in conjunction with nannofossil datum levels allow identification of most of the marine isotope stages (MIS) shown in the LR04 stack since MIS 63 (1.76 Ma).
