Abstract:
Here we present a new astronomically tuned age model for ODP site 887. Age control points established by correlation of GRAPE WBD at site 887 to our site 883 composite and the excellent shipboard magnetostratigraphic age model, with reversal depths updated to fit the new composite section. Where paleomagnetic polarity reversals were recorded in sediments from both 887A and 887C, the mean composite depth of the reversal was used for the age model. In all cases, the discrepancy of the paleomagnetic reversals in composite depth between 887A and 887C was approximately the same as the sampling interval of the magnetic inclination measurements (10 cm).
