observatory's operational procedures, including instrumen- tation testing. The upgrade is to be operational after a trial run lasting three to four months, during which all the sen- sors, junction box and software will be tested. End-User Availability Every plug in the junction box will have a unique IP ad- dress corresponding to one seafloor observation sensor us- ing TCP/IP. All the sensors, including equipment being test- ed, can work and be controlled separately by users. All real-time data will be available in a password-protect- ed graphic download via WebGIS on the observatory's web- site, which is under construction. If an end user is testing equipment, the corresponding data will be available only to that user. Data from a few sensors may be made available to the public in a limited time frame. Conclusions Through the testing and upgrades, the East China Sea Sea- floor Observatory will become an integrated network and test bed for marine instrumentation testing and validation. The observatory will not only accumulate experiences in technology, engineering and test sensors for observation but will also pave the way for performing scientific projects using the long-term continuous, integrated observation platform. The observatory will play a role in Canada's VENUS (Vic- toria Experimental Network Under the Sea) and NEPTUNE (North-East Pacific Time-series Undersea Network Experi- ments) projects, and the MARS (Monterey Accelerated Re- search System) project in the U.S. Acknowledgments The authors are grateful to Pinxian Wang, who is in charge of the Xiaoqushan Seafloor Observatory program.

The authors give special thanks to pro- fessor Chuanlun Zhang from the University of Georgia. n Huiping Xu, a professor at Tongji University, has bachelor's and master's degrees in applied geophysics and a Ph.D. in geoexploration and information technology. His main re- search interests are seafloor observation, data processing in exploration geophysics, GIS and remote sensing. Yang Yu, a Ph.D. student of the School of Ocean and Earth Sciences at Tongji University, received a bachelor's degree in geoexploration and information technology in 2010. He is researching the architecture of the remote controlling sys- tem in the East China Sea Seafloor Observatory. Rufu Qin received his Ph.D. in geoexploration and informa- tion technology from Jilin University in 2006. He is now a lecturer in the School of Ocean and Earth Sciences at Tongji University. His research interests include GIS, data visualiza- tion and the seafloor observation system. Access Sea Technology Anywhere Sea Technology magazine will soon be available on iOS and Android devices.
