The Pilot Project highlights two main subsets of available data - homogeneous distribution in time and space (basins) and not homogeneous distribution in time and space (basins). Guidelines and tools for generating standard interpolated maps and time series plots for ocean data products are provided. Recommendations include focusing on selected parameters, nutrients in the water column, and annual/seasonal scales, among others. The use of specific software and metadata collection guidelines are outlined as well. Links to references and data products are included for further information.

The Pilot Project Highlighted 2 main subsets of available data: Homogeneous ditribution In time and space (basins) Not homogeneous ditribution In time and space (basins) Expert workshop, summary of decisions for Products: -Standard Diva Interpolated maps produced for parameters with homogeneous and suitable data coverage, measured on basin scale; -“Time series plots”. Showing stations geographic distribution linked to plots of measured time series. This for not homogeneous datasets as: • coastal points repeated in time, • datasets with fragmented coverage.

Guidelines for data products DIVA interpolated maps: • Focus on the selected parameters; • Focus on nutrients in the water column based on data availability; • Focus on annual and seasonal scale based on data availability; • Interpolated maps generated by Diva software; • Metadata file generated by DivadoXML script;

Guidelines for data products Time Series plots: • -Focus on the selected parameters; • -Focus on the parameters with fragmented coverage (spatial/temporal); • -suggested use of ODV software for plots generation; • -ratio of 1plot:1station (EDIOS) :1parameter:1depth; • -metadata collected in a INDEX file (http://www.data-assimilation.net/mediawiki/index.php/OceanBrowser#Observation_index_files ) Recommendations: • -to avoid plots for stations with less than 3 points; • -to avoid linkage lines between single points; • -to provide TS plots in vector format as SVG;
