大洋钻探 1 91航次由两部分组成 :(1 )在西北太平洋深海海底 (WP- 2站位 )钻探并下套管 ,同时将安装用于长期浅海底钻孔观测的宽频道地震检波器 ;(2 )硬岩石重反装置 (HRRS)以及其他设备的工程检验。地震观测是国际大洋地震网站的一个重要组成部分 ,该站位弥补了全球地震网站的
Ocean Drilling 1 91 voyages consist of two components: (1) drilling and casing under the deep sea floor of the Northwest Pacific (station WP-2) and installing a wide-band geophone for long-term shallow sea bottom borehole observations; ( 2) Engineering testing of HRRS and other equipment. Earthquake observation is an important part of the International Oceanic Earthquake website that complements the Global Earthquake website
