L086 Marine Geophysical survey North West Continental Shelf, 1968

The Bureau of Mineral Resources has carried out two large scale reconnaissance marine geophysical surveys in the Joseph Bonaparte Gulf and Timor Sea areas in 1965 and 19670 It is proposed to continue this geophysical reconnaissance to the south over the northwest continental shelf from Ashmore reef to Barrow Island. 16 000 line miles should be covered in 3 months on mainly east-west lines 9 nautical miles apart. The boat speed will be about 10 knots. The survey will be done by Ray Geophysics (Australia) Pty Ltd under contract.

矿产资源局已于1965年与1967年在约瑟夫·波拿巴湾及帝汶海海域完成两次大规模海洋地球物理普查勘测。现拟将该类地球物理普查工作向南延伸至阿什莫尔礁至巴罗岛覆盖的西北大陆架海域，计划于3个月内完成总计16000测线英里的作业，测线主体呈东西走向，间距为9海里。作业船航速约为10节。本次勘测将由澳大利亚雷地球物理私人有限公司（Ray Geophysics (Australia) Pty Ltd）按合同承接实施。
