متن کاملNumerical modelling of mud volcanoes and their £ows using constraints from the Gulf of Cadiz
It is estimated that the total number of submarine mud volcanoes is between 1000 and 100 000. Because many are associated with greenhouse gases, such as methane, it is argued that the global flux of these gases to the atmosphere from the world’s terrestrial and submarine mud volcanoes is highly significant. Clues to the processes forming submarine mud volcanoes can be found in variations to the...
متن کاملChemosynthetic bacteria found in bivalve species from mud volcanoes of the Gulf of Cadiz.
As in other cold seeps, the dominant bivalves in mud volcanoes (MV) from the Gulf of Cadiz are macrofauna belonging to the families Solemyidae (Acharax sp., Petrasma sp.), Lucinidae (Lucinoma sp.), Thyasiridae (Thyasira vulcolutre) and Mytilidae (Bathymodiolus mauritanicus). The delta(13)C values measured in solemyid, lucinid and thyasirid specimens support the hypothesis of thiotrophic nutriti...
متن کاملTotal mercury in sediments from mud volcanoes in Gulf of Cadiz.
Mercury emissions into the environment have both natural and anthropogenic sources. Natural sources include volcanic activity, erosion of mineral deposits (the earth’s crust contains 0.5 parts per million of mercury) (Gochfeld, 2003; Gustin, 2003), association with hydrocarbons (Miedaner et al., 2005; Wilhelm et al., 2006), and volatilization from the oceans, whereas man related sources include...
متن کاملIntegrated analysis of bacterial and microeukaryotic communities from differentially active mud volcanoes in the Gulf of Cadiz
The present study assesses the diversity and composition of sediment bacterial and microeukaryotic communities from deep-sea mud volcanoes (MVs) associated with strike-slip faults in the South-West Iberian Margin (SWIM). We used a 16S/18S rRNA gene based pyrosequencing approach to characterize and correlate the sediment bacterial and microeukaryotic communities from MVs with differing gas seep ...
