西太平洋热带海域是世界公认的海水最深、高温水层最厚的区域,它既是台风的发源地,又是大气中赤道辐合带活动的最活跃的海域。研究这一区域海气相互作用,不仅对全球气候变化会有许多重要发现,而且有助于预测我国气候的演变,为我国经济建设和自然灾害的预防做出贡献。为此,“七五”期间,中 相似文献

High resolution geophysical instruments were used to locate many buried paleo-channels. paleo-lakes, and river mouth paleo-deltas formed during low sea level at the end of Late Pleistocene and Early Holocene. Some paleo-rivers flowed southward into the paleo-lake and others southeastward into the Paleo-South China Sea. It may be inferred from data on buried paleo-channels that sea level remained for some time at the -50m (longest time here). -100m, and -130 to -140 m(lowest level) water depths, and that corresponding paleo-coastlines were formed at the respective depths. 相似文献

七十年代,世界上不少国家的海洋科学调查船都装备了剖面仪系统。我们研制的中深层剖面仪样机,1978年6月经海上试验,获得一千多公尺深的地层记录,效果是好的,为样机进一步完善迈出了可喜的一步。 中深层剖面仪是单道地震测量系统,与海上多道地震测量系统比 相似文献
