An impact assessment of a Fishery Observing System (FOS) network in the Adriatic Sea was
carried out with an ocean circulation model fully-coupled with a data assimilation system.
The FOS data are single point vertical values of temperature collected in 2007. In this study,
we used the Observing System Experiment (OSE) and Observing System Simulation
Experiment (OSSE) methodologies to estimate the impact of different FOS design and
sensors implementation. OSEs were conducted to evaluate real observations and they show …

The impact of a ship of opportunity observation system such as the Fishery Observing
System (FOS) in the Adriatic Sea is assessed for year 2007. The temperature and pressure
observations were made by seven purse seiners and mid-water trawlers in the northern and
middle Adriatic Sea, collecting data in the first 100 m of the water column. The assimilation of
FOS observations corrected the temperature fields significantly, reducing the temperature
root mean square error by 50% during the summer with respect to the simulation. Moreover …
