Dissolved nitrate plus nitrite, nitrite and phosphate from water column of the East Pacific Rise in April 2019 aboard the R/V Atlantis cruise AT42-09

These are dissolved inorganic nutrient concentrations from the eastern tropical north pacific ocean from the water column overlying the east pacific rise at 9°50'N 104°18.14'W including samples in hypoxic water. The measured nutrients are nitrate plus nitrite, nitrite, and phosphate. Samples were collected through two casts, one each on April 9 2019 and April 13 2019 by Dr. Benjamin Tully aboard the RV Atlantis cruise AT 42-09. Samples were run by Chesapeake Bay Laboratory's Analytical services facility following EPA method 353.2 with analysis overseen by Jerry Frank. While the cruise primarily focused on the hydrothermal vent field below, our team focused on measurements of suspended particles in the water column and their microbial communities. These nutrient data supported this analysis. These data support a paper in review titled "Quantitative microbial taxonomy across particle size, depth, and oxygen concentration" lead by Paulina Huanca.

本数据集包含东热带北太平洋（Eastern Tropical North Pacific）东经104°18.14′、北纬9°50′处东太平洋隆脊（East Pacific Rise）上方水柱的溶解无机营养盐浓度数据，涵盖低氧水体（hypoxic water）样品。本次检测的营养盐指标包括硝酸盐与亚硝酸盐总量、亚硝酸盐及磷酸盐。样品由本杰明·塔利（Benjamin Tully）博士于2019年4月9日、2019年4月13日通过两次下潜采集，采集工作搭载于“亚特兰蒂斯号”（RV Atlantis）科考航次AT 42-09。样品由切萨皮克湾实验室（Chesapeake Bay Laboratory）分析服务中心依照美国环境保护署（EPA）方法353.2完成检测，检测工作由杰里·弗兰克（Jerry Frank）负责监督。本次航次的核心研究对象为下方的热液喷口区域，本团队的研究重点为水柱中悬浮颗粒物及其微生物群落的测定，本次营养盐数据为该分析工作提供了支撑。本数据集为宝琳娜·万卡（Paulina Huanca）领衔、目前处于审稿阶段的题为《颗粒物粒径、深度与氧浓度梯度下的定量微生物分类学》的学术论文提供了数据支持。
