“…Physical data were collected from CTD casts, and biogeochemical variables were determined from bottle samples collected at standard levels, with this study focusing in particular on chlorophylla and dissolved inorganic macronutrients (phosphate and nitrate). Further details can be found in Lopez-Jurado et al (2014) and Aparicio-González et al (2015).…”

Numerical modeling is a key tool to complement the current physical and biogeochemical observational datasets. It is essential for understanding the role of oceanographic processes on marine food webs and producing climate change projections of variables affecting key ecosystem functions. In this work, we evaluate the horizontal and vertical patterns of four state-of-the-art coupled physical-biogeochemical models, three of them already published. Two of the models include data assimilation, physical and/or biological, and two do not. Simulations are compared to the most exhaustive dataset of in situ observations in the North Western Mediterranean, built ad hoc for this work, comprising gliders and conventional CTD surveys and complemented with satellite observations. The analyses are performed both in the whole domain and in four subregions (Catalan Shelf, Ebro Delta, Mallorca Channel, and Ibiza Channel), characterized by a priori divergent primary production dynamics and driving mechanisms. Overall, existing models offer a reasonable representation of physical processes including stratification, surface temperature, and surface currents, but it is shown that relatively small differences among them can lead to large differences in the response of biogeochemical variables. Our results show that all models are able to reproduce the main seasonal patterns of primary production both at the upper layer and at the deep chlorophyll maximum (DCM), as well as the differential behavior of the four subregions. However, there are significant discrepancies in the local variability of the intensity of the winter mixing, phytoplankton blooms, or the intensity and depth of the DCM. All model runs show markedly contrasting patterns of interannual phytoplankton biomass in all four subregions. This lack of robustness should dissuade end users from using them to fill gaps in time series observations without assessing their appropriateness. Finally, we discuss the usability of these models for different applications in marine ecology, including fishery oceanography.

“…This multidisciplinary approach allows improved management of shortlifecycle species such as Octopus vulgaris (Vargas-Yanez et al, 2009). All the RadMed oceanographic stations are included in the Mediterranean Operational Network for the Global Observing System (MonGOOS) and in the IBAMar database (Aparicio et al, 2015). Along the Iberian Basin and NW slope, seasonality signals in the vein of Mediterranean Water have been detected in the area, with the vein constrained to the shelf break in the summer and widely distributed in winter (Prieto et al, 2013).…”

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 (OO). Some systems like the tide gauges network has been working for more than 70 years. The IEO 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 IEO Observing System (IEOOS) includes 6 permanent moorings equipped with currentmeters, an open-sea ocean-meteorological buoy offshore Santander and an SST satellital image reception station. It also supports the Spanish contribution to the ARGO international program with 47 deployed profilers, and continuous monitoring thermosalinometers, meteorological stations and ADCP onboard the IEO research vessels. The system is completed with the IEO contribution to the RAIA 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 as navigation, resource management, risks management, recreation, etc, 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 programs Earth observation sponsored by the United Nations or the European Union. The synchronic observation system permits following spatio-temporal description of some events, 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.

“…After that, the nutrients samples are collected using 12 mL vials that are kept frozen at −20 • C until they are analysed in the laboratory. Nitrate, nitrite and silicate concentrations are determined according to the method of Armstrong et al (1967), modified by Grasshof (1969). Phosphate concentrations are determined by the method of Treguer and Le Corre (1975).…”

“…In parallel, all the CTD data, nutrients and chlorophyll a are included in the IBAMar database. IBAMar is a regional database (Lopez-Jurado et al, 2014;Aparicio-González et al, 2015) that brings together all the physical and biochemical data provided by multi-parametric probes and water samples taken during the cruises managed by the Balearic Oceanographic Centre of the Instituto Español de Oceanografía (COB-IEO) during the last 4 decades. Initially it compiled data from hydrographic profiles obtained from CTDs equipped with several sensors, but it has recently been extended to incorporate data obtained with hydro casts using oceanographic Niskin bottles.…”

Abstract. In the Western Mediterranean, the IEO-RADMED monitoring program is already conducting many of the evaluations required under the Marine Strategy Framework Directive (MFSD) along the Spanish Mediterranean coast. The different aspects of the ecosystem that are regularly sampled under this monitoring program are the physical environment and the chemical and biological variables of the water column, together with the planktonic communities, biomass and structure. Moreover, determinations of some anthropogenic stressors on the marine environment, as contaminants and microplastics, are under develop. Data are managed and stored at the IEO Data Center that works under the SeaDataNet infrastructure and are also stored under the IBAMar database. In combination with remote sensing data they are used to address open questions on the ecosystem in the Western Mediterranean sea.
