6. Context
Paradigm change in ocean studies.
Multiplatforms observing systems are combined with
forecasting numerical models in response to science and
society needs.
8/11/2016 Rencontre Pôle - Université de Liège

7. New technologies
– Single platforms ship observations  Multiplatforms observing systems (e.g.
autonomous and remotely operated vehicles, ARGO floats).

8. Satellite products have various applications
– Examples (not exhaustive!):

9. Challenge
– Observing the ocean synoptically in space and time (e.g. from
minutes to months) at global scale in a cost-eective way and long
term run.
– NEED for a Coordinated observation data: Constellation of SmallSats + Combination of
in-situ robotic capabilities will considerably boost the study of the oceans, provide
synoptic views potentially close to real-time (Guerra et al., 2016)
– Detection of targeted features by satellite for driving robotic assets in situ.
– To feed numercial models with collected observations for forcasting (opeartional
oceanography)
– Application: climate change, security, monitoring of the ocean (e.g. plume, front, currents,
SST, sea surface elevation), detection of harmfull events (e.g. anoxic zones, harmfull
Algal bloom), maritime traffic, . . . .
