1. Chemical lot - HOW: Infrastructure set up based on SeaDataNet V1 efficient distributed Marine Data Management Infrastructure; Principle of “ADOPTED AND ADAPTED” SDN Standards for metadata,data and products : metadata  CDI (xml ISO 19115); BODC Standard Vocabs (P021,P011,P061...) for common terms; for background data exchange  ODV data format; Data-products: Diva NetCDF files and ODV plots loaded as WMS layers. Infrastructure: CDI mechanism to access data with data policy management, SDN Security Services for users registrations (CAS), SDN Products viewing Ocean Browser services for discovery, visualization and downloading of products. WMS layers; Sextant products metadata catalogue linked Products viewing services

2. Chemical lot - HOW: Infrastructure set up based on SeaDataNet V1 Principle of “ ADOPTED AND ADAPTED” Softwares: MIKADO → metadata mapping and xml generator NEMO → data formatting tool DIVA software → to produce gridded data products and error maps as NetCDF files, ODV software → for “time series” products generation and QC check

3. Chemical lot - HOW: Web portal developement Portal: JBOSS framework with java engines driving html and css to manage contents; A Postgres database for the contents handling; A wiki done with “wikimedia”  PHP language.
