Resumen:

La necesidad de entender y predecir la evolución del sistema climático en todas sus escalas espacio-temporales, ha propiciado la creación del denominado “Sistema Global de Observaciones del Océano” (GOOS), uno de cuyos principales componentes es la red de observación Argo. Constituida por 3000 perfiladores oceánicos, permite determinar, en tiempo presente, el estado físico de los 2000 primeros metros del océano. El interés y la necesidad de esta red queda avalada al ser incluida dentro de la hoja de ruta redactada por el Foro Europeo Estratégico sobre Infraestructuras de Investigación (ESFRI). Argo-España es la contribución española para el sostenimiento de la red de observación Argo. La participación española siempre ha estado supeditada a objetivos científicos, ya sean como apoyo a objetivos de propuestas independientes aprobadas en el marco del Plan Nacional de I+D+i o como medio para alcanzar objetivos propios del programa Argo-España. Actualmente estos objetivos son: (o) Estudio de la variabilidad del transporte masa y evolución de las variaciones de temperatura y salinidad en el Atlántico Norte (24.5ºN). (o) Circulación estacional en el Índico equatorial. Aproximación geostrófica en las cercanías del Ecuador

Abstract:

The need to understand the evolution of the climate system, to predict the weather with greater accuracy and advance, and to determine the state of the sea for its socio- economic importance led to the development of the Global Ocean Observation System (GOOS) . The benefits of a Global Ocean Observation System, affect a wide range of socio-economic activities and not only in the marine sector. The management and protection of the coastal region requires accurate information on marine weather (waves, currents, etc. . ) and health ( nutrient content , heavy metals , hydrocarbons, harmful algal blooms , etc. . ) of coastal waters to develop policies related to waste treatment and disposal , pollution control , regulation of urban construction , beach protection , flood prevention , distribution and richness of the fishing grounds , ... etc. . Weather prediction from fortnightly to climatic time scales needs of accurate sea state information. This information also facilitates naval operations and maritime traffic. The European projection of this interest in ocean observation has resulted in the creation of Global Monitoring for Environment and Security The Argo observing network, whose idea was born in 2001, is one of the key components of the Global Ocean Observation System, and is one of the facilities included in the roadmap of the European Strategy Forum on Research Infrastructures ( ESFRI ) . The goal of the Argo observing network is to provide a quantitative description of the status of the 2,000 meters of the ocean surface every 10 days. This will allow to understand the spatiotemporal variability from months to decades, including heat and freshwater fluxes. Additionally, Argo data will be used to initialize ocean and atmospheric models, from an operational and research perspective. 1The Argo observing network consists of 3000 profiling floats that provide the necessary coverage to the objectives, this is a float every three 3rd longitude and latitude. The average lifespan of these profilers is 3.5 years and therefore the Argo network will require deploying 750 profilers per year to maintain the coverage indicated. Argo-Spain is the Spanish contribution to sustaining the Argo observing network . The spanish participation is based on scientific objectives, whether in support of independent proposals approved by the National Research council or as part of the its own scientific objectives. Currently these objectives are: (o) Study of mass transport variability and evolution of the temperature and salinity variations in the North Atlantic (24.5 ° N). (o) seasonal circulation in the equatorial Indian Ocean . Geostrophic approximation near the Ecuador
