Technological innovation demonstration report

Résumé

The technological innovation demonstration activities within the JERICO-S3 project’s WP7 work package have showcased significant advances for ocean observation. Three observing system solutions have been demonstrated that combine the physics, chemistry and biology compartments: The Autonomous Coastal Observing Benthic Station (ACOBS), the Water-Sample Filtering and Preservation Device (WASP) and the Plankton dynamics Sensor Package (PSP). ACOBS integrates data from various sources simultaneously, such as bottom seawater characteristics, diffusive and total oxygen fluxes at the sediment-water interface, benthic activity at the sediment-water interface and in the upper sediment column. ACOBS enhances our understanding of coastal processes, sediment-water interactions, and benthic ecosystems. WASP enables automated collection of bulk seawater samples for nutrient analysis and automated filtration of phytoplankton samples for environmental DNA (eDNA) and metabarcoding. The sample collection is complemented by real-time observation of essential ocean variables, including hydrographic characteristics, chlorophyll-a fluorescence, coloured dissolved organic matter fluorescence, and turbidity. WASP contributes to both scientific research and environmental monitoring by providing valuable data on water quality and phytoplankton communities. PSP is built around the COSTOF2 technological core, also used to develop the EGIM (EMSO Generic Instrument Module) and enhances it with new biologically related sensors, including zooplankton and nitrate sensors, and a processing unit that dynamically adjusts the sampling strategy based on real-time observations. The PSP also aims to provide standardised, real-time data flow for plankton dynamics, contributing to a better understanding of marine ecosystems. These three developments collectively advance integrated ocean observation by addressing scientific and technological needs. They represent crucial steps toward a more comprehensive understanding of our oceans and their ecosystems. The deliverable content consists in tables summarising the demonstration mission objectives and outcomes. As reminded in each table, since a Steering Committee decision of the 23-25 April 2024, Brussels, the details of this deliverable have been moved to D7.7 for confidentiality reasons and to allow for using the content in journal publications.
