| This deliverable includes several documents that reflect the operational implementation of the tool FlowCAM / ZooPhytoImage in the framework of REPHY. Among these documents, three reports make an assessment of the entire year 2015, which is not the case with other documents (Master 2 report issued in spring 2015, and minutes of meetings over the year). This summary will be limited to the findings of the three reports providing an updated view of the implementation of the tool. Work completed in 2015 for the operational implementation. The many scans performed in 2015 with the three FlowCAM present at Ifremer (Boulogne‐sur‐Mer, Arcachon and Nantes) allowed, one hand to feed the training sets of the tool FlowCAMZoo/PhytoImage, the other test its routine use.... |

| This deliverable contains all development work of the FastCAM, new tool for fast imaging of the phytoplankton, which took place in 2015. It consists of: One report of the FastCAM and its comparison with the FlowCAM presentation: The FlowCAM enables the digitalization of a sample of phytoplankton with X10 and X 4 magnifications. The first allows a better morphological description and therefore a higher taxonomic resolution but with a longer scan time (16 X). Thus, for routine analyses, only scanning at 4 X is possible. A considerable gain would be able to do an acquisition to the magnification 10 X with a time of analysis more short, comparable to 4 X. A fast flow imaging system has therefore developed in this sense. He was called FastCAM. The system is... |

| Phytoplankton distribution and primary productivity were investigated in the Bay of Seine (eastern English Channel, France) in spring and early summer of 1992 and 1994. In 1992, the horizontal distribution of phytoplankton species was determined over the whole Bay of Seine. In 1994, species distribution and primary productivity were studied along the salinity gradient of the Seine plume and in the neighbouring marine waters. Phytoplankton distribution was characterised by the permanent diatom dominance from early spring to early summer. The spring bloom did not occur uniformly over the bay, but was initiated in the marine waters, in the middle of the bay and progressed towards the coast where it developed, in June, in the diluted waters of the Seine plume.... |

| In the Urdaibai estuary, despite its small volume in relation to the tidal prism, phytoplankton grows massively in the upper and intermediate zones of the estuary during summer when rainfall is low to moderate. Data obtained in 23 sampling transects along the longitudinal axis of the estuary, undertaken in July 1993 and August 1994, showed three distinct zones in terms of the phytoplankton species composition: in the upper zone the phytoplankton assemblage was dominated by the diatoms Cyclotella spp., the dinoflagellate Glenodinium foliaceum, cryptophytes and euglenophytes; in the intermediate zone the diatom Chaetoceros ceratosporus, the dinoflagellates Peridinium quinquecorne and Prorocentrum minimum and cryptophytes were the most abundant; in the lower... |

| Biomass and phytoplankton photosynthetic response were studied in the lower Tagus estuary weekly, and related to environmental conditions in February, March and April 1994. The Photosynthesis-Irradiance ((P-I)-I-B) relation was studied based on the light-saturated photosynthesis rate (P(B)m) and the light-limited initial slope (a(B)). The nutrient concentrations observed were high enough to be considered as not limiting phytoplankton growth. Tagus estuary phytoplankton seems, to a certain extent, adapted to high turbid conditions, being able to utilize the low light levels more efficiently, which was translated by high values of a(B) [0.10-0.20 mg C (mg Chl a)(-1) h(-1) (W m(-2))(-1)]; however, light seems to limit phytoplankton production in the water... |

| L’Ifremer met en oeuvre, à l’échelle de l’ensemble du littoral métropolitain, une surveillance de la qualité du milieu marin côtier pour répondre aux objectifs environnementaux de la Directive Cadre sur l’Eau (DCE), aux obligations des conventions régionales marines (OSPAR et Barcelone) et aux objectifs sanitaires réglementaires concernant le suivi de la salubrité des coquillages des zones de pêche et de production conchylicoles. Cette surveillance s’appuie sur plusieurs réseaux de surveillance : le réseau de contrôle microbiologique (REMI), le réseau de surveillance du phytoplancton et des phycotoxines (REPHY), le réseau d’observation de la contamination chimique (ROCCH) et le réseau de surveillance benthique (REBENT). Ces réseaux sont mis en oeuvre par... |

| Le LER/MPL joue un rôle important dans la mise en œuvre des réseaux côtiers d’observation et de surveillance des écosystèmes marins et de la ressource de la Bretagne sud et des Pays de Loire sur les trois départements (Morbihan -56-, Pays de Loire -44- et Nord Vendée -85-). Cet écosystème anthropisé et productif (zones de production de Mytilus edulis, Crassostrea gigas, Ostrea edulis, Pecten maximus), sous l’influence des deux grands fleuves, la Loire et la Vilaine constitue la zone littorale la plus à risque vis-à-vis de l’eutrophisation au niveau de la côte Atlantique. Les réseaux permettent l’acquisition et la qualification de nombreuses données qui sont utilisées pour répondre aux avis et expertises réalisés en appui aux politiques publiques notamment... |
