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

\"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 potassium oxide 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.综合大洋钻探计划（Integrated Ocean Drilling Program, IODP）329航次搭乘“乔迪斯·决心号”（D/V Joides Resolution）科考船，于2010年秋季赴南太平洋环流区执行科考任务，首席科学家为Steven D’Hondt与Fumio Inagaki。本次航次的核心目标之一是探明极低总活性条件下，海底以下沉积物中微生物群落的栖息环境、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布设两条断面，在7个站位（U1365至U1371）完成了全部沉积物柱样的取芯工作。 本数据集公开了IODP 329航次采集的全沉积物样品的氧化钾浓度测量数据。本次样品由波士顿大学Richard W. Murray教授在航次期间采集，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。
