Axis 1 leaders: Alex Costa da Silva, Fabrice Hernandez & Anne Lebourges-Dhaussy

In Axis 1 TAPIOCA proposes developing specific capacity on ecosystem acoustics (Axe 1.1) and turbulent microstructure measurements (Axe 1.2). A third mid-term objective (Axe 1.3.) is to build in Recife the group of reference in the western tropical Atlantic for the French-US Surface Water & Ocean Topography (SWOT) satellite to be launched in 2021.

 

Axis 1.1. Ecosystem acoustics

Problematic and gaps:

Underwater acoustics: multi-component observations of abiotic and biotic ecosystem characteristics. No local expertise.

Scientific and technical capacity building:

Objective: development of savoir faireon ecosystem acoustics.

Main follow-up:

Launch a Chair in Acoustics

 

Axis 1.2. Microstructure vertical measurements

Problematic and gaps:

Ocean mixing: impacts both the climate system and marine resources. Lack of local capacities.

Scientific and technical capacity building:

Objective: turbulence in situ measurement with up to date methods; train the members of the Platform.

Main follow-up:

Oceanographic cruises to measure and model turbulence mixing/dissipation (e.g, AMAZOMIX proposal, PIRATA cruises, …).

 

 

Axis 1.3. Referent structure for SWOT

Problematic and gaps:

Current satellites cannot resolve features <10 km that play a significant role in circulation, biochemistry and ecosystem function.

Scientific and technical capacity building:

Develop operational oceanography tools for monitoring the Tropical Atlantic.

Main follow-up:

Anticipate CNES-NASA SWOT (Surface Water and Ocean Topography) launch in 2021 and organize a SWOT-Ocean Brazil group.
