“…Interface Waters (A-MIW, Gascard and Richez, 1985) eastwards into the W. The pattern of phytoplankton distribution following the mixed layer, and thus shoaling from west to east across the front, was consistent throughout the three fine scale surveys. During FSS3, however, distinct tongues of fluorescence were observed lying between the 27.4 and 28.4 σ 0 isopycnals at the bottom of the thermocline, under the surface waters of the Alboran gyre and extending to depths of ~200 m (Figure 4).…”

“…These latter stations are close to the Strait of Gibraltar, a well-known region of water mass exchange between Atlantic Ocean and Mediterranean Sea marked by salinity and temperature gradients (Gascard and Richez, 1985;Béranger et al, 2005). The Mediterranean Sea presents a range of trophic conditions and it is known to harbor endemic phytoplankton species (for example, Gómez, 2006).…”

Diversity and oceanic distribution of prasinophytes clade VII, the dominant group of green algae in oceanic waters

Prasinophytes clade VII is a group of pico/nano-planktonic green algae (division Chlorophyta) for which numerous ribosomal RNA (rRNA) sequences have been retrieved from the marine environment in the last 15 years. A large number of strains have also been isolated but have not yet received a formal taxonomic description. A phylogenetic analysis of available strains using both the nuclear 18S and plastidial 16S rRNA genes demonstrates that this group composes at least 10 different clades: A1-A7 and B1-B3. Analysis of sequences from the variable V9 region of the 18S rRNA gene collected during the Tara Oceans expedition and in the frame of the Ocean Sampling Day consortium reveal that clade VII is the dominant Chlorophyta group in oceanic waters, replacing Mamiellophyceae, which have this role in coastal waters. At some location, prasinophytes clade VII can even be the dominant photosynthetic eukaryote representing up to 80% of photosynthetic metabarcodes overall. B1 and A4 are the overall dominant clades and different clades seem to occupy distinct niches, for example, A6 is dominant in surface Mediterranean Sea waters, whereas A4 extend to high temperate latitudes. Our work demonstrates that prasinophytes clade VII constitute a highly diversified group, which is a key component of phytoplankton in open oceanic waters but has been neglected in the conceptualization of marine microbial diversity and carbon cycle.

“…At the surface (0 -~200 m), inflowing Atlantic water enters the Mediterranean basin (Millot, 75 1999). On its way, it mixes with upwelled MOW within the Strait of Gibraltar (Folkard et al, 1997) and with surface waters of the Alboran Sea, creating the Modified Atlantic Water with temperatures of 15-16 °C and salinity of 36.5 (Millot, 1999), which follows two anticyclonic gyres, the Western Alboran Gyre (WAG) and the Eastern Alboran Gyre (EAG) (Gascard and Richez, 1985;Vargas-Yáñez et al, 2002). The northern Alboran Sea is affected by upwelling along the Spanish coast providing nutrients and enhanced 80 primary productivity (Minas et al, 1991;Peeters et al, 2002;Sarhan et al, 2000).…”

Abstract. Mediterranean-Atlantic exchange through the Strait of Gibraltar plays a significant role in the global ocean-climate dynamics in two ways. On one side, the injection of the saline and warm 10 Mediterranean Outflow Water (MOW) contributes to North Atlantic deep-water formation. In return, the Atlantic inflow is considered a sink of less saline water for the North Atlantic Ocean. However, while the history of MOW is the focus of numerous studies, the latter has received little attention so far. The present study provides an assessment of the Mediterranean-Atlantic exchange with focus on the
