  1. EMODnet -Progress Meeting- Chemistry Lot A. Giorgetti M. Vinci – 7 th February 2012 , Bruxelles -

  2. Chemical Lot -Introduction and summary of last year; -WPs activities/progresses discussion; -Summary of project activities; -Lessons learned; -Agenda specific questions.

  3. NORTH SEA BLACK SEA MEDITERRANEAN SEA Chemical lot – WHERE - focus on the 3 Geographic areas Regional Leaders: North Sea – NERI Black Sea– MHI Med Sea – HCMR 5 spots

  4. Chemical lot – WHAT- the Parameters • Choice based on MSFD requirements • Time series, geographically representative datasets • Selected from 8 groups in 3 matrices • 17selected for product generation in the three regions

  5. Summary of last year activities First half:the main activities were: • Data collection & Metadata compilation; • Products Generation; • Coordination activities. Second half: • A Critical revision of Products began in September 2011. • A preliminary work for products QC was donefor each partner. This brought to the open discussion of the last Liverpool coordination meeting; • Beside this, following the suggestions of MODEG advisory group, the viewing services were upgraded.

  6. WP2 Data Collection Metadata compilation • Status at February2012

  7. WP2 North Sea • Samples per parameter (described by CDI)

  8. WP2 Med Sea

  9. WP2 Med Sea

  10. WP2 Black Sea

  11. WP2 Black Sea

  12. WP3 QC/QA and Products

  13. Products generation work flow summary...About available data and related products... Available data Homogeneous ditribution In time and space (basins) Not homogeneous ditribution In time and space (basins) Expert workshop –Venice, September 2010-discussion and 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”. Show station maps with plots of measured time series (not trendsnot Emodnet Chemistry target) with link to metadata. Thisfor not homogeneous datasets as: • coastal points repeated in time, • datasets with fragmented coverage.

  14. Products generation work flow summary Work done by Regional Leaders Work shared between NODCs Homogeneous ditribution In time and space (basins) Not homogeneous ditribution In time and space Metadata collection (new) DIVAdo Xml Tools for “Time series” plots, suggested ODV Diva software for NetCDF maps Index file (By Gher) (By Gher) Products Metadata Catalogue (By AWI) (By IFREMER) (By Gher) Ocean Browser Products viewing service

  15. Products generation work flow summary and tech dev Work done by Regional Leaders Work shared between NODCs Homogeneous ditribution In time and space (basins) Not homogeneous ditribution In time and space Diva software for NetCDF maps Tools for “Time series” plots, suggested ODV (new) DIVAdo Xml Metadata collection Index file (By Gher) (By Gher) Ocean Browser (By AWI)

  16. WP3 – QC/QA and Products

  17. WP3 – QC/QA andProducts Products QC (for Diva maps): -Scientific QC of the source data is the first step (to ensure that only trustworthy data will be used for the gridding procedure); • the periodiceducated evaluation of the gridded field for each Region is the core element in QC process, to identify and check: • analysis parameter and temporal resolution; • source datasets that needs to be checked again.

  18. WP3 – QC/QA Products Revision: Maps -MediterraneanSea: Adriaticarea: • torevisetheanalysistemporalresolution(fromannual-->toseasonal); • torevisetheDIVAanalysisparameters(S/Nration,correlationlengths); • toreducetheextensionoftheinterpolatedfieldtothenorthernsideofAdriatic; • toimprovethedefinitionoftheregulargrid toavoidoverlapping betweentheinterpolatedfieldandthecoastline. Spanisharea:arevisionoftheinterpolatedmapsisexpected(tocheckwithchemicalexpertswinternitratemap); Frencharea:acriticalrevisionofseasonalproductsisexpected; Cyprusarea:acriticalrevisiontotheavailablemapsisexpected. • ;

  19. WP3 – QC/QA Products Revision: Maps Black Sea: -focus on nitrate and phosphate for products validation (with expert QC check); - a selection of products is needed between SeaDataNet and Emodnet maps (now both available on the Ocean Browser). Greater North Sea: - the interpolated maps will be better at seasonal scale – agreed that this generally is the best way to represent data – Greater North Sea will maintain its seasonal definition, eg: winter as Dec to Feb;

  20. Path from DATA to PRODUCTS (time series products sample) NODC – TS Sample volounteers: OGS, BSH and 3 Regional Leaders Create: - Plots with ODV - INDEX file Commonly agreed ratio: 1plot:1sta:1param:1depth Images of time series, ... GHER OceanBrowser Map (GetMap) and URL of images (GetFeatureInfo)

  21. TS products – products available until now -

  22. TS products sample extended to OGS, BSH and Regional Leaders

  23. WP3 – QC/QA Products Revision Time series: • Defined a minimum number of points per plot, set to 4; • Use of scatter points plots (avoid lines to connect plotted measures); • Svg format for new plots

  24. WP4 Tech Development

  25. WP4 -Tech Development- About Ocean Browser viewing service... As suggested by MODEG products menu are now at the same level

  26. WP4 -Tech Development- Products Metadata Catalogue • ...from Camioon to GEONETWORK: • First idea→ to manage Chemistry Lot products metadata with • Camioon service used by MyOcean. Several analysis highlightedthat it • does not match SDN/Emodnet needs. • Actual situation → Geonetwork open source software will now be adopted • for this task. It was experimented with Ifremer Sextant Geoviewer. • The products metadata profile XML ISO 19139 need to be checked. • Maps Metadatahas been loaded from DivadoXML by Regional Leaders; • TS plots Metadatamanually loaded by partners in Sextant CMS. • http://www.ifremer.fr/geonetwork/srv/en/main.home

  27. -Chemitry Lot- Activities summary • First year activities → • Set up of the web portal (OGS), filled with core services (Gher, Maris). • Working group Mailing lists were activated (OGS). • All Partners started Data collection and metadata compilation (WP2). • Regional Leaders & Gher group. Products generation and web visualization. • Second year activities → • Continuation of data collection, metadata compilation and products generation . • Expert meetingto discuss data and metadata complexity. TS products generation was common agreement. • Web questionnaire (BODC) for users Feedback to increase portal functionalities . • Started TS plots generation(OGS,BSH,IFREMER) and web prototype (Gher).

  28. -Chemitry Lot- Brief activities summary Third year activities: • Continuation of data collection, metadata compilation . • Continuation of TS plots generation (all partners) and Diva maps. • Updates for the web as suggested by MODEG advisory group. • Products critical revision (from September 2011) A Coordination group open • discussion followed revision, this brought to a Validation Guideline available • on the web.

  29. -Chemitry Lot- Lessons Learned Source data are not always easily accessible → need to improve data flow (MSFD reporting); For some areas huge work of data/metadata standardization from source datasets; The complexity of the measurements covering 8 groups of parameters collected on 3 matrices → need to have wide metadata description and continue with adapting process ofSDN infrastructure; The geographic heterogeneity of the measurements (coastal points time series Vs homogenous sampling) and of measurement methods (instrument, method, target species, target basis, grain sizes) → need to split subsets of homogeneous datasets to generate suitable products; The “exotic parameters” → need an ad hoc QC protocol; Products → need to have a regular expert revision; Users → need to evaluate different classes of users as planned in SDN2

  30. -Chemitry Lot- Anybody using data? – year 2011 AWstats- Web portal CDI OceanBrowser

  31. -Chemitry Lot- What products for the Directive Reporting? → we could make Diva products with observations before a key date (such as when the MSFD was implemented) to compare any change after implementation; → we could produce histograms (in ODV), that can tell how "exceptional" a given measurement is relative to all previous measurements; → we could evaluate long-term trends. However, this was not recommended during the Experts workshop (to be undertaken by other initiatives); → we could consider nutrients ratio (with silicates, nitrogen and phosphorus); → we could include additional metadata with products, if needed; → we could consider products related to parameters like chlorophyll, DO, AL and CORG in EMODNET chemistry. Plots along a coast can be produced already from the Diva maps as a vertical section.
