report. sources of data (spreadsheet), inventories, answers to questions
The first year of EMODNET Chemical pilot activity was dedicated to set up the system components (the three internal regional data pools dedicated to the product generation, the SeaDataNet vocabularies used for chemical parameters mapping and their extension to cover all the EMODNET Chemical lot parameters, the portal core services, discovery and viewing systems based on SeaDataNet CDI interface ).
The main difficulties in the EMODNET Chemical pilot are represented by the data complexity management.
The measurements we are dealing with are related to:
- 8 groups of parameters (pesticides, antifoulants, pharmaceuticals, heavy metals , hydrocarbons, radionuclides, fertilisers, organic matter)
- 3 matrices (sediment, water column and biota).
The Chemical Lot is facing the management and standardization of the heterogeneity of data and metadata:
- the sampling (coastal points time series Vs homogenous sampling on basin scale)
- different measurement methods and targets (instrument, method, target species, target basis, grain sizes)
Great attention on the collection and management must be kept. Will be crucial to provide the best metadata available describing for example: sediment fraction measured, dry/wet weights measurements, measurement methodology. This in order to help a correct comparison between homogeneous sets of data and analysis. The continuous update and upgrade of SDN common vocabularies will help to manage this.
It is clear that the use of DIVA standard interpolation is suitable only for the more “classic” sets of parameters measured in the water column.
For the parameters measured in the other two matrixes such as Biota and Sediment the spatial and temporal distribution of available data highlighted the need of a different commonly agreed analysis approach.
An Expert workshop (Venice, September 2010) was organised to deepen the discussion and define the most appropriate way to represent the data. The cooperation with Marine Conventions (OSPAR, HELCOM and BSC) and MEDPOL was crucial for products definition and for the success of the workshop.
The conclusion of the Expert workshop were:
- To show data availability maps. The matrix “Variables VS Marine regions” described in the technical development section could be a good answer to this.
- Standard Diva Interpolated maps will be produced for parameters with suitable data coverage, measured on basin scale.
- For parameters with a spatial coverage like:
- coastal points repeated in time
- datasets with fragmented coverage
the common idea is to focus the Chemical lot activity on the need to make a good work of analysis, normalization and metadata collection in order to obtain homogeneous datasets well described. Then the idea is to show stations on maps linked to ODV pre-calculated plots that describe the time series of measurements for each parameter considered.
The next Phase will be focused on:
- Progress with data population, analysis, normalization, products generation and dataset updates;
- Common products generation with the extension to the time series (ODV plots) and technical solutions to link them to the viewing service (WMS);
- SDN infrastructure upgrade to manage data complexity VS adopted standard needs (vocabularies, products metadata).
First Interim Report
letter indicating what has changed
EMODnet Chemical pilot is focused on the groups of chemicals required for monitoring the Marine Strategy Directive:
- synthetic compounds (i.e. pesticides, antifoulants, pharmaceuticals),
- heavy metals,
- radionuclides;
- fertilisers and other nitrogen- and phosphorus-rich substances;
- organic matter (e.g. from sewers or mariculture);
- hydrocarbons including oil pollution.
This First Interim Report describes the activities carried out during the first year of EMODnet chemical pilot ( 4th of June 2009 – 3rd of June 2010 ), the deliverables produced by each work package as specified in the Technical Tender Form for Lot 3 – Chemical Data and any deviation from the project tender.
Based on SeaDataNet experience, the following strategy was proposed as approach for the EMODnet pilots:
- Develop a high-end dedicated portal, outfitted with a powerful spatial database, that is complemented with WMS, WFS and WCS services (OGC) to serve users and to provide layers for e.g. the other EMODnet portals, the prototype European Atlas of the Seas, and the broad-scale European Marine Habitats map;
- Provide data sets for producing interpolated maps with specific resolution for each geographical region, that are loaded and integrated afterwards into the portals’ spatial database;
- Include a metadata discovery service in the portal, by adopting the SeaDataNet CDI metadata standard, that inter alia gives clear information about the background data, the access restrictions and distributors; this also ensures the connection of the EMODnet portals with the SeaDataNet distributed infrastructure.
In fact, EMODnet Chemical lot has used SeaDataNet V1 infrastructure for the technical set-up. This means:
- SDN Standards for background data, metadata and product,
- CDI mechanism to access data with data policy,
- ODV format for background data exchange,
- SDN Security Services for users registrations, and SDN Delivery Services for data access and downloading,
- DIVA software tool to produce gridded data products and error maps as NetCDF files,
- SDN Products catalogue (CAMIOON system) and SDN Products viewing services for free unlimited discovery, access, visualization and downloading of data products.
This First Interim Report is organised into 4 sections, where the progress made in the 4 work packages according to the tender planning of activities is summarised. These are:
- Project management,
- Data collection and metadata compilation,
- QC/QA and products,
- Technical development and portal operation.
Some final remarks are given in the final section.
