devoted to investigate the behaviour of the sensor system under flow conditions to simulate the situation when the frame is moved or towed in the water. Here, hydrodynamic tests were performed and compared with model calculations using computational fluid dynamics. Further to these investigations, the marinised optodes are being subjected to chemical tests under flow condition. Fig. 4 shows the SERS optode in such an experiment. Fig.4 SERS optode in a flume tank experiment The objective of this task is to characterize the sensor’s response under controlled large scale conditions. This is the final test of function of the assembled instrument necessary before moving the SOFIE system to the stage of field trials. Initial results with the SERS optode showed encouraging response in the frequency and time domain detecting pollution with a naphthalene cloud in the flume tank. CONCLUSION AND OUTLOOK The construction of SOFIE prototype instrument is finished with CI and SERS optode. The other optodes and the FT-IR instrument are nearly finished. The equipment is currently engaged in the testing phase under controlled large scale conditions. Fig. 5 shows as an outlook, the SOFIE system mounted to the open frame ROV which is under construction. Fig.5 SOFIE system integrated into an open frame ROV In conclusions we may state that the optode-based instrument has promising potential for qualitative and quantitative detection of pollutants and chemical parameters in sea-water. The sensitivity is high enough to reach the low ppb level with selected analytes and with response times in the range of few minutes. The palette of analytes and their limits of detection are certainly subject to further improvement. 699
The concept of optodes linked to a core spectrometer offers great flexibility to fit for different deployment scenarios and future applications. It is a new analytical tool opening interesting perspectives for in-situ measurements - not only to the ocean scientist. ACKNOWLEDGEMENTS The SOFIE project is funded by the European Community within the MAST III Programme under the contract no. MAS3-CT97-0157.
