Measuring the cored sediments every 2 to 4 cm on the MST provided us with the highest temporal resolution data set collected during Leg 177.
Physical properties are a function of sediment composition, structure, and porosity.
Glacial-interglacial fluctuations in sediment composition were observed in GRA bulk density. High values in sediments at the northern sites are consistent with overall high carbonate contents, particularly in interglacial intervals. The opposite is observed in the alternating glacial deposits that have higher terrigenous percentages. At Site 1094, magnetic susceptibility and NGR show high signal amplitudes, but with different character. This indicates that both signals contain different information regarding terrigenous sediment components.
