Annotated record of the detailed examination of Mn deposits from JOIDES Preliminary Cruise with M/V Caldrill I on the Blake Plateau

In May 1964 the Institute of Marine Science (University of Miami), Scripps Institution of Oceanography (University of California), Woods Hole Oceanographic Institution, and Lamont Geological Observatory (Columbia University) joined in the establishment of the JOINT OCEANOGRAPHIC INSTITUTIONS DEEP EARTH SAMPLING (JOIDES) program. The long range purpose of this organization is to obtain continuous core samples of the entire sedimentary column from the floors of the oceans. It was decided that initial efforts would be limited to water depths of less than 1000 fathoms (6000 feet), and tentative locations were selected for drilling operations off the eastern, western and Gulf coasts of the United States. Near the end of December 1964 it was found that the M/V Caldrill I, a drilling vessel capable of working to depths of 6000 feet, was to engage in drilling operations on the Grand Banks of Newfoundland during the summer of 1965 for the Pan American Petroleum Corporation. Thus it was agreed to organize a drilling program along the track of Caldrill between California and the Grand Banks. Selection was made of an area on the continental shelf and the Blake Plateau off Jacksonville, Florida. Based upon many previous geological and geophysical investigations by the participating laboratories, a considerable body of knowledge had been gained about this region of the continental-oceanic border. For this initial program of JOIDES, the Lamont Geological Observatory was chosen as the operating institution with J. L. Worzel as principal investigator, and C. L. Drake and H. A. Gibbon as program planners.1964年5月，迈阿密大学海洋科学研究所（Institute of Marine Science, University of Miami）、加州大学斯克里普斯海洋研究所（Scripps Institution of Oceanography, University of California）、伍兹霍尔海洋研究所（Woods Hole Oceanographic Institution）与哥伦比亚大学拉蒙特地质观测站（Lamont Geological Observatory, Columbia University）联合发起了联合海洋机构深海钻探计划（Joint Oceanographic Institutions Deep Earth Sampling, JOIDES）。该组织的长期宗旨为获取大洋底完整沉积柱的连续岩芯样本。初步钻探作业被限定在水深小于1000英寻（6000英尺）的海域，并初步选定了美国东海岸、西海岸及墨西哥湾沿岸的钻探点位。1964年12月底获悉，“M/V Caldrill I”这艘最大作业水深达6000英尺的钻探船，将于1965年夏季为泛美石油公司（Pan American Petroleum Corporation）在纽芬兰大浅滩开展钻探作业。为此各方商定，沿“M/V Caldrill I”从加州前往纽芬兰大浅滩的航线组织钻探计划，选定区域位于佛罗里达州杰克逊维尔外的大陆架与布雷克高原（Blake Plateau）。基于参与实验室此前开展的大量地质与地球物理调查，学界已对该大陆-海洋交界区域积累了相当丰富的认知。针对JOIDES的首个钻探计划，选定拉蒙特地质观测站作为执行机构，由J·L·沃泽尔（J. L. Worzel）担任首席研究员，C·L·德雷克（C. L. Drake）与H·A·吉本（H. A. Gibbon）担任计划规划者。
