Core D11956T/P (T stands for trigger core; P for piston core) was collected from the Tagus Abyssal Plain in 1989, photographed, and the magnetic susceptibility logged in 1992 with a Bartington Instruments point source sensor at a 2 cm resolution ^^ (Lebreiro, PhD., 1995). The core had been stored for 30 years and the sediment had dried considerably, when magnetic susceptibility was rerun using a Geotek MSCL-XYZ at BOSCORF (Southampton National Center) in 2019, with increasing resolution to 0.5 cm. Therefore, the depth of the elements had to be restored to the original depth. Depth correction was performed by adjusting the curves of the magnetic susceptibility acquired in 1989 and replicated in 2019.
