Results from manganese nodules analyses from the Cook Islands area in the Pacific Ocean

This cruise was undertaken as part of the CCOF/SOPAC Work Programme CCSP-1/CK-1 (Sea bed investigation for manganese nodules in oceanic areas adjoining Cook Islands), CCSP-1/CK-2 (Distribution and economic potential of submarine phosphate deposits in Cook Island waters), CCSP-1/CK-3 (Investigation for precious coral in the near shore waters surrounding the Cook Islands), and CCSP-1/CK-4 (Study of sediments and sedimentary processes of beach, lagoon and adjacent offshore areas of Rarotonga and other islands to assist with coastal management programmes). Manganese nodules were recovered in the Pacific Ocean from the Maniki Plateau and the South Penrhyn basin areas. These samples were analysed using atomic absorption analysis (AAS) by the Australian Mineral Development Laboratory.本次科考航次隶属于CCOF/SOPAC工作计划，涵盖四项专项任务：CCSP-1/CK-1（毗邻库克群岛的大洋区域锰结核海底调查）、CCSP-1/CK-2（库克群岛海域海底磷酸盐矿床分布及经济潜力研究）、CCSP-1/CK-3（库克群岛周边近岸海域贵珊瑚资源调查）以及CCSP-1/CK-4（针对拉罗汤加岛及其他岛屿的海滩、泻湖与邻近近海区域的沉积物及沉积过程开展研究，以辅助海岸管理规划工作）。本次航次在太平洋的马尼基高原（Maniki Plateau）与南彭林盆地（South Penrhyn basin）区域获取了锰结核样品。上述样品由澳大利亚矿产开发实验室采用原子吸收分析法（Atomic Absorption Analysis, AAS）完成分析检测。
