The objective of this task is to develop EOV synthesis products from WP2 and WP3 networks and historical data sets for ocean, carbon, ecosystem and climate research. We will develop an innovative methodology to merge satellite ocean colour and Bio-Argo in-situ measurements into 3-dimensional fields of ocean biological and biogeochemical EOVs (chlorophyll concentration, backscattering coefficient) [D7.9] [PML, UPMC]. Within task 7.5 we will provide surface carbon EOV syntheses [D7.10]: Preparation of intermediate data products based on the most recent SOCAT release, augmented with pCO2 data from the AtlantOS networks that will be subject to secondary QC [UiB]. Usage of statistical techniques to produce a proof-of-concept for the feasibility of ocean carbon system estimates resolving seasonal and inter-annual variability [CNRS]. We will provide ocean carbon interior syntheses by integrating WP2 andWP3 data in the GLODAP data base [D7.11] [GEOMAR]. The GLODAP data product includes EOVs such as the carbonate system (pH, DIC, TA), inorganic nutrients, transient tracers, oxygen, carbon isotopes, salinity and temperature. We will further provide temperature, salinity and oxygen syntheses of the Atlantic Ocean over the last 10 years [Ifremer]. These products will be used to compute ocean climate indices such as heat and freshwater content and steric sea level variations [D7.12)]. Extension toward the South-Atlantic will be achieved as function of data availability (in particular for oxygen). Task 7.5 will provide ecological EOVs from CPR rich biodiversity data [SAHFOS]. Processed EOVs will target specific areas relevant to observing change and will directly deliver key information of significant societal relevance such as human health climate change impacts on ecosystems, ocean acidification, biodiversity and fisheries [D7.13]. The impact of in-situ surface current observations (mainly drifter and ADCP data) on merged high resolution satellite/in-situ surface current products will be quantified [D7.14] [CLS, Ifremer] based on the ESA Globcurrent project.
