EVALUACION DE LA SENSIBILIDAD DEL BUCLE MICROBIANO AL IMPACTO DE MULTIPLES FACTORES EN ECOSISTEMAS ACUATICOS MEDITERRANEOS OBJETIVOS: De acuerdo con los planteados en el proyecto Microsens, los objetivos de la campaña serán los siguientes: 1. Cuantificar la biodiversidad de la comunidad planctónica, mediante la determinación de: 1.1 La abundancia y biomasa de bacterias y picoplancton autótrofo 1.2. La composición taxonómica, abundancia y biomasa de fitoplancton 1.3. La composición taxonómica, abundancia y biomasa de nanoflagelados y ciliados. 1.4. La composición taxonómica, abundancia y biomasa de micro y macrozooplancton. 2. Cuantificar el flujo de carbono entre los distintos grupos funcionales que constituyen el bucle microbiano y la cadena de consumidores, para lo cual se llevarán a cabo medidas de la producción primaria y respiración en diferentes fracciones del plancton 3. Determinar las respuestas funcionales y metabólicas de la comunidad planctónica ante cambios en el espectro de radiación solar y en la concentración de nutrientes mediante experimentos de micro-cosmos realizados a bordo.

FICARAM cruise aims to investigate the evolution of decadal anthropogenic carbon and to evaluate the CO2 uptake capacity in the sector South Atlantic Ocean and its spread to Ecuador and Nord-tropical zone. The section of this cruise is a repeat section following the trace made in 1994 by IFREMER (Laboratoire de Physique des Oceans) into the French project CITHER as a WOCE (http://wwz.ifremer.fr/lpo/Moyens-a-la-mer/Les-campagnes-a-la-mer/Cither-2). This section was repeated in 2001 and 2002 by the Oceanology Group of the Instituto de Investigaciones Marinas of CSIC as part of CAVASSO and CARBOOCEAN European projects. This section is part of the international programs GOSHIP (http://www.go-ship.org/CruisePlans.html) and IOPCC. These programs allow the coordination between the various activities in the global ocean (http://www.go-ship.org/RefSecs/GOSHIPMap_April2011.pdf). The objectives of this cruise are framed in the EU FP7 project CARBOCHANGE (http://carbochange.b.uib.no/) under grant agreement nº 264879. Another important component of FICARAM cruise aims examine the biological and biogeochemical mechanisms that hinder total dissolved organic carbon (DOC) remineralisation in marine systems, taking a multidisciplinary perspective and applying many different approaches. This objective is the global objective of the Spanish project DOREMI that join this FICARAM cruise. Along the section, the DOREMI project will test the effect of different factors (carbon and nutrient additions, and microbial structure) on DOC degradation in epipelagic, mesopelagic and deep waters, developing some experiments determining the potential degradability of mesopelagic and epipelagic DOM, and the role that labile C supplements plays regulating this process and by the microbial structure.

The objective of the project RADIALES, formulated in 1990, aims at “understanding and modelling the response of the marine ecosystem to the sources of temporal variability in oceanographic and planktonic components, particularly foccusing in those factors and processes affecting biological production and potentially altering the ecosystem services”. This project represents the oldest multidisciplinary ocean observation initiative still active in Spain.
