The observations provided by oceanographic remote instruments are essential to the purposes of the operational oceanography that represents a constantly growing tool to monitor and predict the state of the marine resources. The management of a network of instruments deployed in the Mediterranean Sea is a complex task that may be greatly supported by the GRID technology. This paper presents the activity planned by the DORII EU-FP7 project concerning the floats and the glider. The aim of the project is to demonstrate the potentiality of the state-of-the-art eInfrastructure in the integration of the data driven control/interaction workflow that characterizes the instruments. We describe the communication between the elements of the workflow and the associated network topology.
