“…Mud volcanoes and mud diapirs are common features in the Alboran Sea in the Western Mediterranean (e.g., Sautkin et al, 2003) and along the Atlantic margin of the associated Gulf of Cadiz (e.g., Pinheiro et al, 2003;Somoza et al, 2003;Fernandez-Puga et al, 2007). Mud volcanism and associated phenomena such as cold seepage, hydrocarbon venting and gas hydrates in the Gulf of Cadiz have been investigated since 1996 (Baraza and Ercilla, 1996;Baraza et al, 1999;Ivanov et al, 2000Ivanov et al, , 2001Somoza et al, 2000;Gardner, 2001;Kenyon et al, 2001;Mazurenko et al, 2002;Pinheiro et al, 2003).…”

An exploratory cruise of R/V Belgica in 2002 on an accretionary setting in the Gulf of Cadiz (Gutscher et al, 2002) off Larache (Morocco), led to the discovery of a cluster of nine mud volcanoes: the El Arraiche mud volcanoes field (Van Rensbergen et al, 2005).…”

Growth and demise of cold-water coral ecosystems on mud volcanoes in the West Alboran Sea: The messages from the planktonic and benthic foraminifera

The Dhaka and Maya mud volcanoes (MVs), located in the Mud Diapir Province in the Western Alboran Basin along the Moroccan Coasts, were cored during the TTR-17, Leg 1 cruise. Cores were taken on the top of the volcanoes at a water depth of 370 m on the Dhaka MV (core TTR17-MS411G) and at 410 m water depth on the Maya MV (core TTR17-MS419G), respectively. On both mud volcanoes the extruded mud breccia provides the nucleation point for the colonization and development of cold-water corals and associated ecosystems. Two phases of cold-water coral growth are observed: (1) between slightly older than 4175± 62 years BP and around 2230± 59 years BP at Dhaka, and (2) between slightly older than 15583 ± 185 years BP and around 7613 ± 38 years BP at Maya MV. On the top of the Maya MV only a small patch reef and/or isolated corals proliferated, whereas a more extended patch reef colonized the top of the Dhaka MV. At both sites the cold-water coral development was triggered by the availability of a suitable substrate for initial coral settling, provided either as a firm ground or as single clasts. Subsequently coral growth was supported by enhanced nutrient flux possibly related to upwelling and/or strong currents. During the intervals of coral growth planktonic foraminiferal assemblages were dominated by Neogloboquadrina incompta. The decline of coral ecosystems on the mud volcanoes is accompanied at surface by a shift from the N. incompta dominated assemblage to a Globorotalia inflata dominated assemblage, possibly reflecting more oligotrophic conditions. This shift is coeval to the passage from wet to arid conditions at the end of the African Humid Period at Maya MV. It is interpreted as an effect of an early human impact on a fragile environment, which was already stressed by desiccation at the time of the development of complex human society along the Mediterranean coasts, at Dhaka MV.

“…For more than a decade, the international marine scientific community has deployed considerable efforts in studying the occurrence of mud volcanism, cold seepage and gas hydrates in the Gulf of Cadiz (Baraza and Ercilla, 1996;Pinheiro et al, 2003;Somoza et al, 2003). Since the discovery of the Gulf's first mud volcano in 1999, research cruises have steadily unveiled one mud volcano after another (Gardner, 2001;Pinheiro et al, 2003;Somoza et al, 2003;Van rensbergen et al, 2005).…”

“…The compression between the Eurasian and African tectonic plates creates an interesting geophysical template (Sartori et al, 1994;Maldonado et al, 1999;Gutcher et al, 2002) shaped by volcanic activity and by the interaction between the topography and the circulation of the Atlantic and Mediterranean Waters (Peliz et al, 2007). Found in water depths between 200 and 4000 m, these mud volcanoes are clustered in several fields on the Portuguese, Spanish, and Moroccan margins and show considerable variations in dimension, morphology and composition of erupted material and fuids (Pinheiro et al, 2003;Van rensbergen et al, 2005;Hensen et al, 2007;niemann et al, 2006).…”

SuMMArY: Collections of Frenulata made by the rV Professor logachev in the Gulf of Cadiz in 2006 contain two new species, one belonging to the genus Spirobrachia, and another that was assigned to a new genus. Spirobrachia tripeira n. sp. is the first record of the genus in the north Atlantic ocean; it has a very stiff, straight, orange tube; its tentacles have pinnules and are arranged in a spiral crown without a lophophore. Bobmarleya gadensis n. gen. et n. sp. is characterised by an unusually long tentacular crown composed of about 40 free tentacles. it shares many characteristics with the genus Oligobrachia but the large number and extreme length of the tentacles and a combination of other characters justify the designation of a new genus. The specimens of Lamellisabella denticulata Southward, 1978 collected during the M.S. Merian 03/01 cruise provide the first record of this species in the Gulf of Cadiz.
