Background and Objectives
During the last few years, a significant number of projects were carried out to promote the use of the Earth Observation (EO) by satellite to the benefit of aquaculture and fisheries sectors (ACRI and Planetek Hellas have a long past of successful collaboration on exploitation of EO). The EU funded SAFI project has been the opportunity to establish deep relationship with aquaculture professionals and to a better level understanding of their requirements about environmental monitoring. A service has been put in place to supply aquaculture professional with EO derived data.
EO can regularly provide synoptic and useful information on the environment (Harmful Algal Blooms or HABs, thermal fronts, water quality) thanks to the Sentinel Programme of Copernicus. However, its standalone use is limited as key parameters like local current speed and direction are not retrievable from space. In addition, the spatial coverage of the imagery might be impacted by clouds presence or its quality affected by sun specular reflection.
We thus propose in EOSAI to combine EO data and coastal hydrodynamic modeling. This will be demonstrated over two sites (one in France and one in Greece) and will allow to get access to current fields to complement diagnostic for farms deployment, providing answers to :
- Where to put cages with an optimal water circulation?
- Are the farms vulnerable in case of external pollution?
- Where are dispersed the farms effluents? etc.)
and to offer prognostic on environmental issues :
- if a HAB or a surface pollution is detected, where will it drift in the next coming hours/days?
The EOSAI objective is thus to pursue the dialogue established in past projects and to expand the service offer to new parameters and new services that would be easy to deploy on any site. Copernicus Programme provides operationally modeled currents data for all European regional seas and also at the global level that will be exploited for efficient deployment of local hydrodynamic models.
