Multiplatform measurements to study ocean meso‐submesoscale dynamics
Dra. Maristella Berta (Consiglio Nazionale delle Ricerche- Istituto di 
Scienze Marine (CNR-ISMAR), Lerici (SP), Italy)

The dynamics of the ocean currents and fronts result from the 
interaction of simultaneous mechanisms at different scales. Large and 
mesoscale oceanic features (10 to 100 km, days to weeks) are globally 
monitored through satellite remote sensing, but the submesoscale range 
(a few hundred meters to 10 km, hours to a few days) remains 
particularly challenging to observe directly, due to the high 
variability in both time and space.
The development of multiplatform ocean observatories spanning the sea 
surface as well as the water column and the combination of independent 
and complementary measurements collected in targeted experiments is 
crucial to accurately resolve localized regions of ocean mixing and 
enhanced vertical velocities, such as fronts.
Meso-submesoscale fronts and filaments have been recognized to play an 
important role in the surface dispersion and patchiness of various types 
of tracers (biological, pollutants and marine debris) as well as in the 
transfer from the surface to the interior ocean.
Research efforts are put into the networking of multidisciplinary 
observing systems, on the optimization of multiplatform experiment 
strategies, and on the development of methods to blend multiplatform 
observations in order to reconstruct the 4‐D circulation and the 
current-driven passive transport. No less important is the development 
of metrics to unravel submesoscale properties, to estimate vertical 
velocities within the sea surface layer, and the response of sea 
properties to atmospheric forcing. The talk will introduce the subject 
and discuss some recent applications in the framework of different 
international scientific collaborations.

Maristella Berta holds a Master in Environmental Physics (Univ. of 
Torino, Italy) and a PhD in Environmental and Industrial Fluid Mechanics 
at the Univ. of Triesten (Italy). Her interests are mainly devoted to 
the reconstruction of the 3D ocean current dynamics and to the 
combination of sea observations coming from complementary instruments 
and approaches. The developed techniques and metrics are applied to the 
investigation of meso and submesoscale dynamics through the analysis of 
targeted Lagrangian observations in combination with Eulerian and 
modeled data. She participated and coordinated several Lagrangian 
experiments and coordinated an international multiplatform experiment in 
the Mediterranean Sea.

¡¡Les esperamos!!
