The cruise mainly focused on two areas in the Hola Trough: at node 7 where methane seeps have been mapped, and further north (node 1) where are located cold coral reefs. The aim of the cruise was to characterize the seafloor and local biology, bubbles characteristics, the water column chemistry and methane dynamic. We also performed corals transplant to study adaptation and installed Piezometers and temperature probes for fluid flow calculation. The cruise may be known as: CAGE22_3
