“…11). The high abundance of shallow infaunal taxa in mesotrophic settings is attributed to a diversification of infaunal niches (Milker et al, 2009). The present-day current system in the northern Gulf of Cádiz can be used as a possible analogue for the paleoceanographic setting in the study area during the Messinian.…”

Benthic foraminiferal assemblages of a drill core from the lower Guadalquivir Basin (northern Gulf of Cádiz, SW Spain) have been analysed in order to reconstruct the paleoenvironmental evolution in the vicinity of the Betic seaways during the Messinian. The core consists of marine sediments ranging from the latest Tortonian to the early Pliocene. Changes in the abundance of certain marker species, planktonic/benthic ratio (P/B ratio), paleodepth estimated with a transfer function, content of sand grains and presence of glauconitic layers indicate a complete transgressive-regressive sea-level cycle from the bottom to the top of the section. An abrupt sea-level rise, from inner-middle shelf to middle slope, is recorded at the lowermost part of the core (latest Tortonian-earliest Messinian), followed by a relatively rapid shallowing from middle slope to outer shelf. Magnetobiostratigraphic data show These assemblages are dominated by Nonion fabum and Bulimina elongata, two taxa that are able to feed from continental low-quality organic matter, most likely derived from river run-off. The paleoenviromental evolution on the Atlantic side of Betic and Rifian seaways is similar during the Messinian, with a Messinian continuous sea-level lowering driven by regional tectonic uplift and upwelling-related waters reaching the upper slope. This study will further contribute to understand the role of tectonics on the sea-level changes as well as on the closure of the Atlantic-Mediterranean gateways that led to the MSC, and on the paleoceanography on the Atlantic sides of these corridors.

“…In the DCA plot, it is located very close to C. ungerianus indicating it high quality food preferences. S. sagittula species has been reported as a common shelf species in the Mediterranean associated to sandy substrates and also to energetic environments (de Stigter et al, 1998;Milker et al, 2009;Schönfeld, 2002).…”

“…The Balearic shelf can be divided into two geographic sectors: the Mallorca-Menorca shelf, covering 6418 km 2 , and the smaller Eivissa-Formentera shelf, with a total surface of 2709 km 2 (Acosta et al 2002 ). Coastal detritic bottoms have been largely identified on the Mallorca-Menorca shelf (de Buen 1934, Alonso et al 1988, Forn ó s et al 1988, Canals and Ballesteros 1997, Forn ó s and Ahr 1997, Massut í and Re ñ ones 2005 and have been characterized in terms of Foraminifera (Milker et al 2009 ) and mega benthos (Massut í et al 1996 , Massut í and Re ñ ones 2005 , Ordines and Massut í 2009 ). Seaweeds are a major component of these coastal detritic bottoms, but they have been taken into account in a somewhat cursory manner in descriptive studies that try to cover all benthic groups (e.g., de Buen 1934 , Canals andBallesteros 1997 ); the only literature providing a full list of seaweeds thriving on these bottoms is the description of Peyssonnelia and ma ë rl beds by Ballesteros (1994) .…”

Abstract:We present a quantitative physiognomic characterization of major macroalgal-dominated assemblages on coastal detritic bottoms of the continental shelf off Mallorca and Menorca (Balearic Islands, Western Mediterranean). In late spring of 2007 and 2008, 29 samples were collected by bottom trawling at depths between -52 and -93 m. These samples were then sorted and identified to their lowest taxonomic level. Statistical analyses distinguished six different assemblage types: shallower water environments (-52 to -65 m in depth) were characterized by Osmundaria volubilis and Phyllophora crispa meadows and two types of Peyssonnelia beds; two assemblage types, Laminaria rodriguezii beds and ma ë rl beds, were only present in deep-water environments (-77 to -81 m); and an assemblage dominated by P. crispa and Halopteris filicina was found in both shallow and deep waters (-57 to -93 m). We assess the distribution of these six assemblage types through the studied area.
