SOARC/SOMLIT - High Frequency: Arcachon Bay Observation Service/Coastal Environment Observation Service (UMR EPOC)

The Arcachon Bay Observation Service (SOARC) is a local deconvolution of the Coastal Environment Observation Service (SOMLIT: http://somlit.epoc.u-bordeaux1.fr/fr/), certified as an Observation Service by INSU (1996) and as an Observation platform by LabEx Cote (2013). Since 1997, the PFO SOARC/SOMLIT has taken an interest in the functioning of Arcachon Bay (a continent-ocean interface) and in its long-term evolution. The current bimonthly sampling strategy does not allow for taking into account the frequently intense impulse phenomena which can have a powerful effect on the functioning of coastal ecosystems. The objective of the current project is to set up High Frequency monitoring with a limited series of parameters (temperature, salinity, turbidity, fluorescence) in addition to the current low frequency monitoring with a wide-ranging series (16 physical, physico-chemical, biogeochemical and biological parameters). The PFO SOARC/SOMLIT data are obtained using a quality-controlled approach (the SOMLIT quality system is based on the ISO 17025 standard) and are available on the SOMLIT website. The same applies to the High Frequency data. The High Frequency data will potentially be used by the different LabEx COTE teams studying Arcachon Bay (ECOBIOC, METHYS, EA, LPTC, LER IFREMER), the GEO-TRANSFERT cell and the socio-economic stakeholders (CRC - Regional Shellfish Farming Board, SIBA - Arcachon Bay Inter municipal Union).

PINELINE: Development of a database relating to radial micro-variations of maritime pine trunks associated with environmental variations (UMR BIOGECO)

The PINELINE project is a "Database" platform for storing and for facilitating access to high-throughput phenotyping data on radial micro-variations and environmental data for the maritime pine populations. These phenotyping data, linked to the tree's water status, have been used since 2011 by BIOGECO geneticists as an indicator of the trees' response to abiotic stresses.  They are recorded in the field every 5 minutes thanks to electronic dendrometers attached to the trees, in parallel with environmental variables (ground humidity, height of the water table, temperature, incident radiation) recorded at the same frequency.

Our PINELINE project has two principal objectives: i/ the construction of a database specifically dedicated to this kind of high-throughput phenotyping and environmental data, ii/ accessible to the scientific community thanks to a customized interface. PINELINE will also participate in the maintenance of field monitoring devices installed as part of other completed projects (Abiogen ERDF project) or ongoing projects (Fortius region project, the ANR WUETree project). PINELINE will be designed to be inter operable with other existing databases such as Pinus Portal for genetic data (https://w3.pierroton.inra.fr/PinusPortal/). This platform will be a tool both for researchers at the BIOGECO unit and at Labex COTE, but also for external researchers at national or international level whose research topics concern the adaptation of trees to climate change (STReESS COST Action European network: http://streess-cost.eu/).

ResIntBio: OASYS project: "Low input" vineyard AgroSystems Observatory OASys (UMR SAVE)

The ResIntBio platform, located since 2011 at the INRA Grande Ferrade site, aims to evaluate the performance of vineyard agrosystems with low consumption of inputs and to document their operation. Thanks to an experimental randomized device, the ResIntBio platform can compare 3 systems with different approaches to the use of pesticides (i) a conventional system (using organic pesticides) (ii) a biological system (using inorganic pesticides) (iii) a system using no pesticides. The multi-criteria assessment is carried out with the help of agronomic indicators (quality and quantity of production, growth of pests, functioning of the plants), economic indicators (working time, costs) and environmental indicators (pesticide consumption, fuels).

The objective of this project is to complete this observatory by incorporating data regarding the transfer of organic and inorganic pesticides (copper) in various environments (soil, air, groundwater). This observatory is part of the national Dephy-Expe network; it is open to any project designed to assess the impact of the reduction of the usage of pesticides on the vineyard agrosystem.

VitAdapt: observatory of the evolution of vine phenology in the context of climate change (URM EGFV)

VitAdapt is a vine phenotyping platform which aims to study the effect of climate and genotype on phenology, yield components and grape composition. It was set up in 2009 on the INRA (National Agronomic Research Institute) Grande Ferrade campus. Its originality lies in the fact that all potential sources of variation in phenology and fruit development are perfectly controlled. Indeed, the scheme includes 52 genotypes planted on a single rootstock, with 5 repetitions of 10 strains, meaning that any soil variability within the plot can be disregarded (Figure 1). Furthermore, the crop management technique is perfectly controlled. Accordingly, the only variable factors are the genotype and the weather conditions of the relevant year. This platform is open to LabEx COTE researchers. As part of its basic objectives, the scheme generates data that allow for improvements in phenology models and fruit maturation models. Amongst the most applied objectives, is the gathering of data on a great number of varieties with the result that the vines genetic diversity can be used to help them adapt to a changeable climate.
