WP5: Observatory Infrastructure

The existing but fragmented European glider infrastructure is analysed in WP5, and a future European infrastructure for gliders will be defined based on what exists. A focus will be given to 1) the currently existing, distributed ground-segment , 2) the glider scientific payload, 3) the tools to plan/dimension the glider effort to be made in order to fulfil the scientific objectives defined in WP2 and WP3 and 4) the costs of the individual Member State glider activity. All activities in WP5 will serve as input to WP1 assessment.

Task 5.1 Ground segment description

(responsible: HZG, contributors: UCY, IFM-GEOMAR, CNRS, UIB, CSIC, PLOCAN, SAMS, NERC) Describe in detail the role “gliderports” will play in the infrastructure, This will include the description of the entire ground segment of the glider operations, such as equipment and building facilities required for maintenance, repair, testing, calibration, ballasting. The required logistical needs regarding deployment, recovery, shipping will be described, as well as the required tools and equipment for piloting gliders and collecting and transferring the observational data to data centres. Finally, the number and distribution of “gliderports” will be recommended. start month 1 – end month 33

Task 5.2 Glider payload assessment

(responsible: UCY, contributors: IFM-GEOMAR, HZG,FMI, CNRS, NURC, UIB, CSIC, PLOCAN, UEA, NERC) An overview and assessment of sensors predominately used on gliders will be provided: measured parameters, power requirements, method, if any, of performance assessment, and usefulness or acceptability of their data. Recommendations for incorporation of new sensors on gliders will also be provided: desired parameters, existing sensors for each parameter, integration requirements (communication, power), and suggestions for assessing their performance. Based on these recommendations, the most mature technology in terms of glider integration will be developed or purchased, integrated, and (in WP4) tested. Finally, assessment of sensor performance and data quality will be achieved by the development of an inter- calibration/inter-comparison system, which allows the verification of glider sensor measurements with “conventional and widely acceptable” methods (e.g., chemical analytical methods, calibrated CTD sensors). The system will consist of documentation describing sampling protocols (if necessary), analytical protocols, inter-calibration/inter-comparison mission procedures, and data analysis procedures. The above activities will be finalized only after the execution of specific field exercises by WP4.

Task 5.3 Mission planning and analysis

(responsible: NURC, contributors: UCY, UPMC, CNRS, HZG, AWI, FMI, NERSC, CSIC, NERC) In order to maximize the use of resources and utility of measurements collected by gliders, mission need to be designed with the desired outcomes in mind. In particular, the processes (and therefore time and space scales) of interest must be identified. These processes vary by region and time period as well, so sophisticated tools have been developed to plan missions to achieve certain goals. This task will design a glider mission planning system for the glider observing network using the following science and technology approach: 1) develop approaches for glider fleet observation system sampling experiments (OSSE) and observing network optimisation, 2) determine the impact of the environment (currents, waves, winds) on the success of glider missions, 3) analyse glider mission risk against maritime and littoral activities, and 4) integrate mission planning tools with ocean observatories. The effectiveness of a particular mission is evaluated with post-processing tools, namely data assimilation tools, which will be evaluated in this package as well. The recommended tools for planning and analysis will be tested in WP4. start month 1 – end month 30

Task 5.4 Estimated setup and running costs

(responsible: CNRS, contributors: All) The costs associated with implementing the tasks above will be analysed in detail. These costs include 1) costs to build infrastructure (one time only, such as building, software development, equipment purchases for outfitting glider ports), 2) costs to operate the infrastructure (staff, refilling stock, building running costs, consumables), and 3) costs to operate gliders (gliders themselves or their effective depreciation, communications, batteries, calibrations, servers, pilot staff). start month 1 – end month 33
