Cruise Inventory Information

Long name RRS James Cook (740H) cruise JC010_2 (JC10)
Short name JC010_2 (JC10)
Objectives and Narrative The major objective of RRS James Cook 10 was to increase our understanding of how seafloor environmental variables affect the biodiversity, structure, function and dynamics of faunal communities in two specific 'biological hotspot' environments, mud volcanoes and submarine canyons, on the NE Atlantic continental slope. The cruise was jointly supported by OCEANS 2025 (Theme 5) and the EU Hotspot Environment Research on the Margins of European Seas (HERMES) project.

The cruise comprises three legs, of which this is the second.

The objective of this cruise was to investigate ecosystems in the Nazare, Cascais and Setubal Canyons where the supply of organic material is considerably greater than on the adjacent continental slopes. To achieve this goal, a series of ROV dives will be made at different water depths to address the following scientific questions:

1) How do the ecosystems vary down canyon, between canyons where the environmental drivers may be different, and between the canyons and the adjacent slopes?
2) What is the small scale variability in seabed faunas related to local topography e.g. boulders, ledges and local changes in environmental parameters e.g. current strength or water mass?
3) Are cold water corals present in the canyons and under what environmental conditions?
