European glider capacity to research and observe oceans
The EU-funded GROOM (Gliders for research, ocean observation and management) project set out to fill gaps in current marine research infrastructures (RIs) for the benefit of science, industry and society. The new European infrastructure is based on several dedicated gliderports for the maintenance and operation of European gliders. GROOM scientists investigated and documented the advantages of using gliders for ocean prediction and optimal sampling in the OOSs as well as the policy and management of data collected by gliders. Authorities were approached regarding safety and legal aspects of glider operations and possible financial models were reviewed. In addition, the team carried out studies on performing synergistic experiments with other platforms and the testing of new sensors. Project partners studied the innovation aspect of operating gliders. They analysed a variety of novel sensors available in the market and under development, as well as their readiness for gliders. These sensors pave the way for broad perspectives in the design of experiments with gliders for physical, chemical and biological ocean research. Data flow and work flow protocols and formats were developed. GROOM also defined and implemented a dedicated data management system for gliders in Europe. Trial glider deployments were undertaken to test and assess the designed fleet operation techniques. Synergies with other ocean observing platforms were also explored, including testing sensor deployment. The team analysed existing European glider infrastructure and defined a future European infrastructure for gliders based on the current state of play. GROOM drew up a roadmap to establish and implement a European RI during the period 2015-2020. It will be most useful for academic oceanographic research and operational oceanography systems, which provide crucial information on marine activities to the commercial sector, governmental organisations and recreational users.
