Statement

Sediment samples were collected from megacores (max 60 cm), pushcores (max 30 cm, one pushcore of 60 cm) and gravity cores. Megacores and gravity cores were wireline deployed over the vessel side. ROV video footage and imaging allowed groundtruthing and precise landing location for megacores and gravity cores. Push cores were taken by ROV. Gravity cores were sectioned into 1 m sections labelled (surface) A to E (base). Sediment samples were collected using cut off syringes and porewater extracted using rhizomes and split into aliquots for different analyses. Megacore and pushcore sediment was sampled by extrusion and slicing 1 cm slices in the top 10 cm, 2 cm slices below 10 cm. Porewater was extracted at similar intervals using rhizomes. Dissolved oxygen measurements were taken using oxygen probes following collection at comparable intervals to sediment and porewater sampling.
