Ocean bottom seismometer survey line OBS2016-2 across the magnetic quiet zone and continent-ocean boundary in the northeastern South China Sea

<p>OBS2016-2 dataset was collect in July, 2016.&nbsp;The ~320 km long NW-SE oriented profile OBS2016-2 is located to the east of the Dongsha Islands, extending from the Chaoshan Depression to the East Subbasin of the South China Sea. Seismic data were collected by R/V Shiyan-2 of South China Sea Institute of Oceanology (SCSIO), Chinese Academy of Science.&nbsp;The seismic sources are composed of four large volume Bolt airguns and the total airgun volume is 6000 in3. The firing interval was 90 s in time and 204 meters in distance, and the sailing speed of R/V Shiyan-2 was about 4.5 knots during the experiment. A total of 1572 shots were fired. Fifteen 4-component broadband OBSs were deployed, and fourteen of them were retrieved successfully with good data records. Data format is SAC.</p>
