| Purpose | Research |
| Objectives | Fourth in a series of five cruises investigating the activity, behaviour and distribution of deep-sea scavenging fish.
Main tasks: 1) Trawling (OTSB) to sample deep-sea fish and invertebrates for a range of studies. 2) Lander deployments to observe in situ behaviour of deep-sea fish. 3) Lander experiments to investigate bioluminescence. 4) Box-coring to sample deep-sea corals. |
