There were 13 cores taken (11 Kasten cores and two piston cores) at depths from 2100 to 3356 metres. Samples for diatom analysis were collected on board ship immediately after core recovery. Samples were dried in an oven at 50 degrees C prior to analytical work. For further details, see cited metadata record.
