OC Research @ CNR CNR OC Research involves: ISAC-GOS (Rome), ISMAR (Venice) and IREA (Milan)
The main aims are to contribute to European Operational Oceanography effort, to monitor the marine environment, to study the marine processes and coastal and inland water
Major Activities:
Development & implementation of the Satellite component of the European Copernicus Marine Environmental Monitoring Service
Development of OC new algorithms/products for European regional Seas and coastal and inland waters
Development of new products based on synergy of OC, SST, Altimeter, SSS, SAR and in situ data
Bio-optics and CAL/VAL
social drivers & operational service development marine environmental monitoring in support to marine policy coastal issues oil-spill pollution search and rescue Fishery
CNR role in CMEMS

OC PRODUCT EVOLUTION: (2018-2021)
• Sentinel 3A OLCI data streams in the NRT/DT/REP multi-sensor processing chains • Inclusion of Sentinel 3B OLCI & VIIRS//NOAA-20 • Evolution of the chlorophyll algorithm with a focus on optically complex waters
(particularly Baltic and Black sea) • Improvement of the L4 Chlorophyll products • Full resolution ocean colour (OLCI 300m) for European coastal areas • Phytoplankton type variables • Primary production (for Global ocean) • Long term chlorophyll trends and Ocean Monitoring Indicators

River plume structure variability • For Po River prodelta, Landsat 8 scenes from two paths:
Revisit time is 7-9 days, instead of the standard 16 days. • Turbidity patterns in the Po river prodelta as function of river
discharge, wind and wave to describe fine scale processes at 30m
Braga et al, 2017 ECSS; Manzo et al 2018, JAG
Correlation of Turdibity vs Discharge
High correlation values provide an envelope of plume persistence and extension
Key ingredients:
•Coastal Suspended Sediment Load
•Coastal Current
Toward an operative Coastal Morphodynamic monitoring and diagnosis
Shoreline evolution depends on along shore gradients of sediment
flux Qs
Positive flux divergence in absence of river discharge indicates areas subject to erosion processes
Use of OC data for sustainable fishery
Ichthyoplanktonic data: position, time, number of eggs and larvae, larvae length and otolith increments (proxy of age).
Going back to “age zero”: lagrangian back-trajectories to reconstruct connections between
spawning and recruitment areas
Chl (r) encountered by the larvae in their backward travel: Only those individuals that travel within Chlorophyll-rich waters have a significant survival probability.
Chl-weighted reconstructed Spawning areas
Objectives : Simulate anchovy eggs and larvae backward evolution to reconstruct location and inter-annual variability of spawning areas

What can we expect using the CMEMS/CNR L4 surface CHL?
(FUTURE WORKS) Improvement of the Altimeter derived currents using
CMEMS/CNR L4 remotely sensed SST
Improvement of the CMEMS L4 altimeter-derived currents via OPTIMAL MERGING with remotely-sensed surface oceanic tracers
Input data Altimetry: DUACS L4 gridded products SST: L4 OI maps (MW & IR) 1 year of global ocean data & Med regional data For validation (independent data): Drifting buoy velocities Chlorophyll L4 map

Significant Improvement of the velocity field for the meridional velocity (up to 20-30% in presence of strong SST gradient ),
