联合探测爪哇海沟俯冲带结构

Core Viewpoint - The joint geological and geophysical survey conducted by the Second Institute of Oceanography of the Ministry of Natural Resources and the National Research and Innovation Agency of Indonesia has successfully completed its scientific tasks, achieving significant results in the deep structure detection of the Java subduction zone [1] Group 1 - The survey lasted 17 days and covered a total distance of approximately 2,800 nautical miles, focusing on active source seismic and controlled source electromagnetic joint detection in the Java Trench subduction zone [1] - Seawater and sediment core samples were collected, and relevant scientific data was obtained during the survey [1] - The collaboration between Chinese and Indonesian scientists resulted in a 100% recovery rate of seabed observation equipment within a limited weather window [1] Group 2 - The seismic and electromagnetic data obtained from the Java Trench subduction zone will provide key evidence for a deeper understanding of the lithosphere's solid-fluid structure and dynamic processes in the region [1] - The Second Institute of Oceanography will closely collaborate with the National Research and Innovation Agency of Indonesia and Gadjah Mada University in subsequent data processing and scientific analysis [1] - This collaboration aims to enhance scientific understanding of the Southeast Asian circum-subduction system's plate convergence theory and the mechanisms of marine geological disasters [1]
