TL;DR: In this paper, a general overview of the geology and geophysics of western Iberia, and in particular of the western Portuguese Margin, is presented, where the links between the onshore and offshore geology, and geophysysics are especially emphasized.

TL;DR: A new deep water mud volcano field (between 2000 and 3500 m water depth) was discovered in the deep South Portuguese margin, as well as several new mud volcanoes in the South Spanish and Western Moroccan margins of the Gulf of Cadiz, during the TTR-10 (Training Through Research, UNESCO/IOC) cruise, in July/August 2000.

TL;DR: Arutyunov et al. as mentioned in this paper showed that thermogenic methane and associated higher hydrocarbons rising from deeper sediment strata are completely consumed within the seabed, and the presence of a distinct sulphate-methane transition zone overlapping with high sulphide concentrations suggests that methane oxidation is mediated under anaerobic conditions with sulphate as the electron acceptor.

TL;DR: In this article, the authors investigated six active sites and found that mud volcano fluids, on average, are highly enriched in CH4, Li, B, and Sr and depleted in Mg, K, and Br.

TL;DR: In this paper, a slope-to-basin sedimentary system comprising 21 sedimentary ridges up to 20 km long was mapped and described, and it was found that the sediments are mainly transported into the deep basins by mass transport processes across the steepest fault scarps forming a channel-levee system, while gravitational slides dominate the shallower slopes.
