“…Nevertheless, other factors, such as the width of the continental shelf (Sabatés, 1990) and mesoscale circulation patterns (Sabatés & Masó, 1992;Torres et al, 2011;Rodriguez et al, 2013) can also control this horizontal distribution.…”

An oceanographic survey was carried out during the summer of 2009, from June 25 to July 3 in the Gulf of Gabes. The study area was characterised by a wide continental shelf.A plankton sampling scheme was carried out to study the structure of the larval fish assemblages that characterised the surface mixed layer, and to assess the influence of the environmental parameters on their spatial distribution.A total of 36 taxa were identified, three classified to the level of genus, five to the family and 28 to the species. The majority of identified fish larvae belonged to the demersal species, mainly picarel Spicara smaris (23.76% of the total larval fish abundance), followed by red mullet Mullus barbatus (14.92%) and several species of the Sparidae family (9.15%). Small pelagic species such as Sardinella Sardinella aurita and European anchovy Engraulis encrasicolus were also abundant (27.75%) and dominated the fish larvae community in offshore stations. Five large pelagic species were found among the larvae, including bullet tuna Auxis rochei, Atlantic black skipjack Euthynnus alletteratus, albacore Thunnus alalunga, swordfish Xiphias gladius and the highly migratory Atlantic bluefin tuna Thunnus thynnus. All these apex predator species appear in 38.5% of the sampling stations and contributed to about 7.9% of the total larval catches.The larval fish assemblage of the Gulf of Gabes is predominantly composed of the neritic species in correspondence with the shallow depths of the study area. Canonical Correspondence Analysis (CCA) showed that larval distributions were mainly conditioned by depth. However, other factors, such as, hydrographic processes, also play a very significant role in shaping the spatial pattern of larval fish distribution.

“…In fact, only a few studies provide information on the entire ichthyoplankton community in which tuna larvae are present in the Mediterranean (Somarakis et al, 2002;Alemany et al, 2006;Koched et al, 2011;Torres et al, 2011;Rodriguez et al, 2013).…”

“…Also near the continental slope, a cascading of colder and even denser water was found , affecting biological processes over the whole water column (e.g. Company et al, 2008;Rodríguez et al, 2013;Carbonell et al, 2014;Hidalgo et al, 2014). In the last years, linked to the growing interest in Mediterranean Sea health state, new variables (pH, Total Inorganic Carbon, NO 2 , CH 4 ) have been added to the original sampling (Amengual et al, 2010).…”

Abstract. Since its foundation, 100 years ago, the Spanish Institute of Oceanography (IEO) has been observing and measuring the ocean characteristics. Here is a summary of the initiatives of the IEO in the field of the operational oceanography. Some systems like the tide gauges network has been working for more than 70 years. The standard sections began at different moments depending on the local projects, and nowadays there are more than 180 coastal stations and deep-sea ones that are systematically sampled, obtaining physical and biochemical measurements. At this moment, the Observing System includes six permanent moorings equipped with current meters, an opensea ocean-meteorological buoy offshore Santander and a sea-surface temperature satellite image station. It also supports the Spanish contribution to the Argo international programme with 47 deployed profilers, and continuous monitoring thermosalinometers, meteorological stations and vesselmounted acoustic Doppler current profilers on the research vessel fleet. The system is completed with the contribution to the Northwest Iberian peninsula and Gibraltar observatories, and the development of regional prediction models. All these systematic measurements allow the IEO to give responses to ocean research activities, official agencies requirements and industrial and main society demands such as navigation, resource management, risks management, recreation, as well as for management development pollution-related economic activities or marine ecosystems. All these networks are linked to international initiatives, framed largely in supranational programmes of Earth observation sponsored by the United Nations or the European Union. The synchronic observation system permits a spatio-temporal description of some events, such as new deep water formation in the Mediterranean Sea and the injection of heat to intermediate waters in the Bay of Biscay after some colder northern storms in winter 2005.
