名为WP-2的新井下地震观测站由ODP Leg191成功地布设在西北太平洋海盆的ODP1179E钻孔。为了研究地球构造,WP-2台站被安置在一个独特的点位。两套宽频带地震仪用水泥固定在玄武岩层内,通过ROV号潜艇来驱动系统并检查系统的工作状态。ROV也用于回收初始数据。WP-2台站的地震噪声水平对地震观测而言是足够低的。
A new downhole seismic station called WP-2 was successfully deployed by the ODP Leg 191 in the ODP1179E borehole in the Pacific Northwest. In order to study the Earth’s tectonics, the WP-2 station is housed at a unique point. Two sets of broadband seismometers were fixed in basalt with cement and the ROV submarine was used to drive the system and check the system’s operating status. ROV is also used to recover the initial data. Seismic noise levels at WP-2 stations are low enough for seismic observations.
