Task 7.1 Development of mobilized planktonic mesocosms

Task 7.2 Emerging automated, high-frequency imaging techniques for breakthroughs in aquatic food web research in mesocosms

Task 7.3 Applying GHG flux measurements to benthic/pelagic and pelagic mesocosms


AQUACOSM-plus WP7 builds on the JRA developments in AQUACOSM, by introducing a series of new approaches to reach the next level in tackling prevailing historical restrictions of non-standard, spatially fixed mesocosm facilities (Task 7.1), as well as methodological restrictions in obtaining high-frequency data on aquatic community change (Task 7.2) and greenhouse gas (GHG) fluxes (Task 7.3). For the latter, development and testing of benthic mesocosms for use in soft sediments is also carried out. These JRAs create new Technological Readiness Levels needed for effective process studies and modelling, on the temporal and spatial scales required for experimental aquatic research tackling climate change-related Grand Challenges.
