Cruise Inventory Information

Long name RRS James Cook (740H) cruise JC010_1 (JC10)
Short name JC010_1 (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 first.

The objective of this leg was to improve understanding of the processes involved in transporting organic-rich fluids from the geosphere into the biosphere. To achieve this goal, a series of ROV dives investigating mud volcanoes in the Gulf of Cadiz, addressing the following scientific questions:

1) What are the rates of fluid venting and what is the source of the fluids?
2) What is the composition of cold-seep communities associated with the mud volcanoes and how do these compare to cold-seep communities from other areas in the Atlantic and elsewhere?
3) What is the total contribution of mud volcanoes to the carbon cycle in the Gulf of Cadiz?
4) Does the new NOC methane sensors produce good results at a range of water depths?
