摘要为了获得典型海洋岛弧系统的详细地壳结构,我们利用日本海洋地球科学技术机构(JAMSTEC)的R/V Karei在伊豆-小笠原地区进行了多道地震(MCS)反射调查。在航行期间,同时观测了swath水深测量、地磁和重力数据。在2004财政年度,我们共收集了2030.9 km的MCS数据:KR 04 -10为228.20 km,KR 04 -13为384.70 km,KR 04 -15为1417.95 km。船上处理结果显示了太平洋俯冲板块、弧前构造特征和弧后盆地结构的清晰地震反射图像,表明采集的MCS数据质量良好。
Abstract In order to obtain detailed crustal structures in a typical oceanic island arc system, we have been conducting multichannel seismic (MCS) reflection survey in the Izu-Ogasawara region, by using R/V Kairei of Japan Agency for Marine-Earth Science and Technology (JAMSTEC). Swath-bathymetry, geomagnetic and gravity data are simultaneously observed during the cruises. In 2004 fiscal year, we collected a total of 2030.9 km of MCS data: 228.20 km in KR04-10, 384.70 km in KR04-13 and 1417.95 km in KR04-15 cruises. On-board processing results demonstrate clear seismic reflection images of the subducting Pacific plate, forearc tectonic features and backarc basin structures, showing that all of the MCS data collected are of good quality.
