Abstract: A total of 260 OBSs were deployed in the marine TAIGER program from late March to late July, 2009. These data were collected by US Columbia University’s R/V Langseth as the big-power seismic shooting ship and 10 Taiwanese ships to take terms for supporting of the OBS experiment in the entire seismic cruises. The OBS were provided by the National Taiwan Ocean University, French IFREMER and Scripps Institution of Oceanography. During these 4 months, we have worked around Taiwan in the South China Sea, Luzon Arc, East Taiwan and West Philippine Basin. All efforts are put together by many earth scientists from Taiwan, USA and France under one major purpose, to get a better understanding of the Taiwan mountain building processes. As a result, these new data will provide as a base to combine with many other disciplinal studies, such as the multi-channel seismic, land recorded seismometer data, gravity and magnetic as well as the natural earthquake data recorded by the OBS during the experiment time. Four very preliminary OBS data analyses will be presented in the same T25 postal section. Beside the research, we also carried out our teaching to our students on board a Taiwanese student training ship, Yu-Yin No.2. Therefore, an educational post is also to be shown in the ED01 section. Even the data analyses are in an early stage, but we are exciting about it. For example, 3 OBS profiles (T4, T5 and T6) in the East Taiwan were shot twice in normal and reversed directions with different shot intervals (30 and 60 seconds per shot). This exercise will be important to interpret the complicate collision/subduction structures in the East Taiwan. Two OBS profiles (T1 and T2) in the Luzon Arc were shot 5 times in the separated R/V Langseth cruises (due to the typhoon effects), again with different shot intervals (20 and 60 seconds per shot). These will provide us more opportunities to examine the collisional features in between Taiwan and Luzon. One OBS long profile (550 km) was shot in the West Philippine Basin. The line was designed at 90 degree angle of the spreading fabric. Two additional OBS profiles were also shot in the South China Sea by Taiwanese shooting ship, R/V Ocean Research No. 1 in 2007 and 2008. We put together the data for a systematical interpretation of the whole TAIGER experiment. Dr. Char-Shine Liu, Francis Wu, Kirk McIntosh and Shu-Kun Hsu were the co-chief scientists on board R/V Langseth of Leg 1, 2 and 4..
