The magnetic record of sediments of Sites 1138 and 1140 established by shipboard measurements is extended and corrected. About 600 sediment cubes were stepwise demagnetized with alternating fields to determine their characteristic remanence. For some samples from Site 1138, standard shipboard demagnetization at 20 mT turned out to be insufficient to obtain the characteristic remanence. Selected samples were examined by laboratory-induced magnetization analysis, hysteresis measurements, and thermomagnetic measurements. Titanomagnetites with varying Ti content are the main magnetic minerals in the sediments of Sites 1138 and 1140.
