Two ITB Researchers Participate in Ocean Research on a Chinese Ship

Two researchers from the Bandung Institute of Technology (ITB), along with nine researchers from the National Research and Innovation Agency (BRIN), Gadjah Mada University (UGM), the University of Indonesia (UI), and China, departed from Tanjung Priok Port to conduct research on marine biodiversity and geology in the waters south of Sumba Island on Sunday (August 10, 2025).

The research, aboard the R/V Tan Kah Kee research vessel owned by Xiamen University, is an initiative of the Second Institute of Oceanography (SIO), China, in collaboration with BRIN, Gadjah Mada University, and the LPDP (Lembaga Penida Disaster Mitigation Agency). The research focuses on the collision zone between the Australian and Eurasian Plates and its impact on geological hazards.

Using various geophysical methods, including floating passive-source seismometers, active-source ocean bottom seismometers (OBS), ocean bottom electro-magnetometers (OBEM), and geological methods such as seafloor sediment sampling and analysis, the study was conducted by Gabriella Alodia, S.T., M.Sc., Ph.D. from the Hydrography Research Group (KK), Faculty of Earth Sciences and Technology (FITB), ITB, will focus on observing supporting data, such as seafloor morphology analysis using a multibeam echosounder, gravity observations using a marine gravimeter, and positioning the OBS and OBEM instruments, which will be placed on the Indian Ocean floor at depths of two to six kilometers using acoustic methods. Meanwhile, research by Dr. Alvina Kusumadewi Kuncoro from the Earth Physics and Complex Systems Research Group, Faculty of Mathematics and Natural Sciences (FMIPA), ITB, will focus on two-dimensional physics-based numerical geodynamic modeling of the survey area.

The resulting geodynamic model will then be validated with observational data from nearby global navigation satellite system (GNSS) frameworks, seismic profiles generated from the OBS, and local earthquake distribution.
