Comment:
The Brunhes/Matuyama (0.75 Ma) and Matuyama/Gauss (2.54 Ma) paleomagnetic boundaries were established using shipboard measurements of natural remanent magnetization (NRM) such as inclination reconstructions (Wefer et al., 1998 doi:10.2973/odp.proc.ir.175.110.1998). An existing age model based on oxygen isotope (delta18O) records from planktonic (Globorotalia inflata) and benthic (Cibicoides wuellerstorfi) foraminifera (Dupont et al., 2005 doi:10.1130/G21401.1) was compared to the alkenone record and the LR04 benthic foraminifera oxygen isotope stack (Lisiecki and Raymo, 2005 doi:10.1029/2004PA001071). Through graphical correlations of peaks obtained from Analyseries 1.2 software (Paillard et al., 1996 doi:10.1029/96EO00259), we improved the previous age model for the past 3.5 Ma at Site 1082. The Pleistocene high resolution alkenone record (1.5-0 Ma) clearly revealed the last fifty glacial/interglacial stages. Patterns of change (3.5-2.8 Ma) in delta18O from benthic foraminifera (Site 1082 and LR04 stack) showed outstanding similarities for the oldest part of the record. For the intermediate period (2.8-1.5 Ma), strong cooling events (Marine Isotopic Stages 58, 78, 82, 96, 100, G6 and G14) were identified in our SST record in agreement with a high resolution alkenone record from the Eastern Equatorial Pacific (Lawrence et al., 2006 doi:10.1126/science.1120395).
