Resumo: | This deliverable contains the work that was carried out in 2014 for the FlowCAM / ZooPhytoImage tool actually becomes a usable operational tool in the REPHY, and as such, can provide results supplying the assessments of WFD phytoplankton indicator. This deliverable is complementary to the deliverable 1, provided for the same action, entitled « Evolutive version of the operational tool for digitization and semi-automated analysis of phytoplankton images, using the FlowCAM device and the Zoo/PhytoImage software. New perspectives » This deliverable has five parts whose content is summarized below.  1. Work done for operational implementation in 2014 under the REPHY. These tasks affect either the scanning operations of the phytoplankton images by FlowCAM, or the using of ZooPhytoImage software.  2. Test the operational capability of the tool in a broader context of campaign to the sea. The system was deployed during the campaign CAMANOC 2014 in Channel. The results will contribute to the improvement of knowledge on phytoplankton compartment to another spatial scale.  3. Scanning Procedure reviewed and adapted to Nantes FlowCAM. Given the fact that the three FlowCAMs are not of the same model, the scanning procedure of the samples, initially developed in Arcachon, required an adjustment, in particular with regard to the computer environment, the formatting system auto focus, and equipment.  4. Report on the evaluation of a common recognition tool Channel-Atlantic 4X. Fusion of training sets built on three sites (Arcachon, Boulogne sur Mer and Nantes). The new error correction techniques added to the new ZooPhytoImage software user interface allowed the evaluation of a recognition tool from a training set consisting of sample images scanned by different FlowCAM, and from both coastlines of the Channel and the Atlantic. Such a comprehensive tool is considered in the context of the evolution of software to active learning and adaptive training set  5. Banking in Quadrige² data from the treatment by ZooPhytoImage of phytoplankton images scanned by the FlowCAM : work progress. Between September 2014 and January 2015, several meetings allowed to work on the first specifications, to estimate the sizes and volumes required for banking, to sketch a first pattern of organization, and to think on the possible aggregation methods of many data which will be available in supplement, that should be structured to fit into Q². Furthermore the interface between the ZooPhytoImage output file and Quadrilabo (file for direct integration into Q² bypassing the classic interface entry), was studied by Mons (described in deliverable 1).
