Abstract. An observing system simulation experiment
(OSSE) is presented in the Sea of Marmara. A highresolution
ocean circulation model (FESOM) and an ensemble
data assimilation tool (DART) are coupled. The OSSE
methodology is used to assess the possible impact of a Ferry-
Box network in the eastern Sea of Marmara. A reference experiment
without assimilation is performed. Then, synthetic
temperature and salinity observations are assimilated along
the track of the ferries in the second experiment. The results
suggest that a FerryBox network in the Sea of Marmara has
potential to improve the forecasts significantly. The salinity
and temperature errors get smaller in the upper layer of the
water column. The impact of the assimilation is negligible
in the lower layer due to the strong stratification. The circulation
in the Sea of Marmara, particularly the Bosphorus
outflow, helps to propagate the error reduction towards the
western basin where no assimilation is performed. Overall,
the proposed FerryBox network can be a good start to designing
an optimal sustained marine observing network in
the Sea of Marmara for assimilation purposes.
