EMODnet Chemistry 2 Advanced services Progress by Deltares Service Contract MARE/2012/10 S By Dick M.A. Schaap – Technical Coordinator Istanbul – Turkey, 15 June 2015, 2 nd plenary meeting

Contract requirements for EMODnet Chemistry gather all measurements of a particular chemical species with their appropriate metadata within a given space and time window visualise the measurement density in a given time and space window visualise a time evolution of a selected group of measurements show concentration plots for a given time and space window and also along the coast calculate spatially distributed data products specifically relevant for selected Marine Strategy Framework Directive Descriptors

NODCs data collection Regional Buffer 1 Central Data Buffer Robot Harvester Regional Buffer 2... Workflow from data to regional data collections Original plan

Regional Buffers Regional Validation Regional QC’d Buffer Time Series DIVA Maps Visualisation Workflow from data collections to products to viewing Implemented Sextant product catalogue

Advanced services The validated and aggregated buffers of data sets are input for the products and advanced services: Interpolated maps as produced with DIVA software Time series graphics for all collected data sets via WPS (Deltares) OceanBrowser viewer (Ulg) as common service for viewing the DIVA maps and giving access to the time series graphics Sextant catalogue (Ifremer) to document all products with metadata

From QA/QC observations to dynamic data products Deltares services ODV to geodata From geodata to information services by OGC WPS services according to user specified choices

OGC services WFS, WPS ODV Metadata enriched ODV files Oceanbrowser Data architecture Step 1 Step 2 Step 3 Step 4

Data model for metadata enriched ODV collections into PostgreSQL/PostGIS database (hosted at CINECA)

Committing ODV data collections to the database Creation of data model Reading QA/QC’d files from regional coordinators Adding vocabularies, EDMO, Local_CDI_ID, Fill table observed_cindex (does not give values, but a color index based on the range of values and transformed to rgb scale) Create/Refresh GeoServer for location and intensity map

Structure of Request What services GetCapabilities Query all observations using cdi Cdi_Get_Parameters Query all observations using bbox Bbox_Get_Parameters Plot a map in binary mimetype Cdi_Plot_Maps Plot a profile in binary mimetype Cdi_Plot_Profiles Plot a timeseries Cdi_Plot_Timeseries Plot a map in binary mimetype bbox_Plot_Maps Plot a profile in binary mimetype bbox_Plot_Profiles Plot a timeseries bbox_Plot_Timeseries Plot a timeprofile Cdi_Plot_Timeprofile Plot a timeprofile bbox_Plot_Timeprofile

Status of regional data uploads – by number of CDI’s (status )

Status of regional data uploads – by number of observations (status )

Spatial distribution by GeoServer layers in OceanBrowser Circles show data location (within depth and time range) Circle are semi- transparent (intensity of a color gives an indication of number of observation points)

Plot of data at selected location as Time Series Clicking on a circle Time series plots (x- axis: time; y-axis: parameter) Depth is represented by color

Plot of data at selected location as Profile One can switch between time series and profile view For profiles (x-axis: parameter and; y-axis: depth) Time is represented by color

Remaining actions by Deltares Tuning and improving speed of viewing service Tuning and improving speed of access by WPS Improving density plots Documentation of services Transfer to MARIS for operation
