| Purpose | |
| Abstract | SO185 prime objective was to recover high resolution sediment archives to decipher the variability of the Indonesian. Throughflow and the Australasian climate history on decadal to millennial timescales over the past 150 000 years. To achieve this objective 58 sediment and water stations were sampled between the edge of the Arafura Sea and the Argo Abyssal Plain in the eastern Indian Ocean. Angular coverage of the EM120 was typically set at 70° because the sea state was so calm. When the ship was slowed to under 10kn during formal surveys the angle could be increased to 72° on each side. The system behaved extremely well during the course of the cruise. |
