The Glomar Challenger定位到原文第二段第二句Using techniques first developed for the offshore oil and gas industry,the DSDP's drill ship,the Glomar Challenger,was able to maintain a steady position on the ocean's surface and drill in very deep waters extracting samples of sediments and rock from the ocean floor.

推理判断题[考频：66]。原文第二段讲述了对海底进行第一次探索的情况。对海底首次进行探索始于 1968年的深海钻井工程，而在这一工程中发挥了主要作用的正是Glomar Challenger，它能在海平面上保持稳定并且能够钻入深水中，从而抽取样本。故D正确。

Taking APCN2 fiber-optic cable system Guard Wire Protection Project on the East China Sea Continental shelf as an example, this paper discussed side scan sonar data applications for undersea cable maintenance.

但是，侧扫声纳无法有效探测既不出露海底又没有明显埋设沟痕的海底光缆，同时也无法确定光缆的埋设深度，对这些状况的了解须结合使用其它专门探测设备。

Said shaft with enclosed two ends passes from marine extraction platform through submarine water-bearing stratum into submarine oil bed and has water pumping and injecting openings corresponding to the water-bearing stratum and oil bed respectively. A sand control filter is mounted to water-pumping opening. A packer is provided in the shaft between water and oil beds.

井筒从海上采油平台穿过海底水层后伸入海底油层中，其井口和井底均为封闭，对应于水层和油层处的筒壁上分别开有抽水孔和注水孔，抽水孔内侧的井筒中装有防砂过滤器，水层与油层之间的井筒中装有封隔器。

During this time, they have witnessed countless sea floor wonders, have found the colliery of sea floor and treasure of the sunken ship, fight with big shark , octopus richly, beat back the siege of the original inhabitant.
