Bulk sediment uranium concentrations from IODP Expedition 329 to the South Pacific Gyre

Abstract: "The Integrated Ocean Drilling Program (IODP) Expedition 329 to the South Pacific Gyre on board the D/V Joides Resolution (Chief scientists Steven D’Hondt and Fumio Inagaki) took place in Fall 2010 and had as one of its major objectives to document the habitats, metabolic activities, genetic composition, and biomass of microbial communities in subseafloor sediment with very low total activity. To meet this objective the entire sediment column at seven sites (U1365 through U1371) were cored along two transects in the region of the South Pacific Gyre.
We present here uranium concentration measurements in bulk sediment samples from IODP Expedition 329. Samples were collected during the expedition by Prof. Richard W. Murray (Boston University) and sample preparation and analysis was performed by Dr. Ann G. Dunlea in the Analytical Geochemistry Facilities at Boston University.

摘要：综合大洋钻探计划（Integrated Ocean Drilling Program, IODP）第329次航次搭乘“乔迪斯·决心号”（D/V Joides Resolution）科考船赴南太平洋环流区（South Pacific Gyre）开展科考，首席科学家为Steven D’Hondt与Fumio Inagaki，航次执行于2010年秋季。本次航次的核心目标之一，是探明总活性极低的海底以下沉积物中微生物群落的生境、代谢活动、遗传组成与生物量。为实现该目标，研究团队在南太平洋环流区的两条断面上，对7个站位（U1365至U1371）的完整沉积物柱完成了取芯作业。

本文报道了综合大洋钻探计划第329次航次采集的bulk沉积物样品（bulk sediment samples）中的铀浓度测量数据。样品由波士顿大学Richard W. Murray教授于航次期间采集，样品制备与分析工作由Ann G. Dunlea博士在波士顿大学分析地球化学实验室完成。
