abstract = {Extensive beds of the deep-sea mussel Bathymodiolus mauritanicus (currently also known as Gigantidas mauritanicus) linked
to active cold seeps related to fissure-like activity on Al Gacel mud volcano, Gulf of Cádiz, were filmed and sampled for the
first time during the oceanographic expedition SUBVENT-2 aboard R/V Sarmiento de Gamboa. Al Gacel mud volcano is one
of up to 80 fluid venting submarine structures (mud volcanoes and mud volcano/diapir complexes) identified in the Gulf of
Cádiz as result of explosive venting of hydrocarbon-enriched fluids sourced from deep seated reservoirs. This mud volcano
is a cone-shaped edifice, 107 m high, 944 m in diameter constituted by mud breccias and, partially covered by pavements
of seep carbonates. Extensive beds of this deep-sea mussel were detected at the northern flank at 810–815 m water depth
associated with bacterial mats around intermittent buoyant vertical bubble methane plumes. High methane concentrations
were measured in the water column above living mussel beds. Other chemosymbiotic species (Siboglinum sp., Solemya
elarraichensis, Isorropodon sp., Thyasira vulcolutre and Lucinoma asapheus) were also found in different parts of Al Gacel
mud volcano. Al Gacel mud volcano may currently represent one of the most active mud volcanoes in the Gulf of Cádiz,
delivering significant amounts of thermogenic hydrocarbon fluids which contribute to foster the extensive chemosynthesisbased
communities detected. This finding is of paramount importance for linking extremophile bivalve populations along
the North Atlantic, including cold seeps of the Gulf of México, hydrothermal vents of the Mid-Atlantic Ridge and now,
detailed documented at the Gulf of Cádiz.},
