Abstract:
Magnetic Susceptibility (Mag Sus) from gravity cores PS128_2-2 (69.4115°S, 5.5897°W) and PS128_2-3 (69.4107°S, 5.5890°W) (less than 100 m apart from each other), which were recovered from Bungenstock Plateau during R/V POLASTERN Cruise PS128 in 2022 (Tiedemann and Müller, 2022). Magnetic susceptibility measurements were conducted onboard using a GEOTEK Multi-Sensor Core Logger (MSCL) on cores PS128 2-2 and PS128 2-3 to assess magnetic mineral content, an indicator of terrigenous sediment variations. The MSCL provided continuous cross-sectional measurements at 1 cm resolution. Raw data were drift and volume-corrected to obtain true susceptibility values (kappa) in 10⁻5 SI units.
