What is it about?
Recently revised satellite altimetry products (AVISO 2104) are shown to better represent near-shore mesoscale activity in the Eastern Boundary Upwelling Systems (EBUS). The increased resolution of these altimetry products impacts on identified eddy radii and thereby on transport estimates, including those issued from composite analysis (satellite+ARGO).

Why is it important?
Eddy-driven zonal transport is known to affect the interannual variability of primary production in the EBUS that supports about 20% of the world fish catch.
Perspectives
These results calls for a reassessment of (1) global eddy-driven fluxes, (2) impacts of mesoscale activity on biogeochemical cycles in the EBUS, using revised altimetry products.
