TN250-10 CTD and Nutrient Data

This Conductivity Temperature Depth (CTD) data set, consisting of 242 casts, was collected during a multi-disciplinary Bering Sea ice cruise on the R/V Thompson (TN250, June 16 - July 13, 2010). The cruise was funded by NSF for the Bering Sea Ecosystem Study-Bering Sea Integrated Ecosystem Research Program (BEST-BSIERP), and supported by numerous agencies and institutions. BEST-BSIERP together are the Bering Sea project. The CTD operations on this cruise were managed by personnel from NOAA/PMEL in the EcoFOCI program, with deployment assistance from Thompson personnel. Water samples from casts were collected by various parties relative to their research needs. Profile data from CTD instruments were processed at NOAA/PMEL/EcoFOCI using standard techniques. Data from bottle samples include phosphate, silicate, nitrate, nitrite, ammonium, and chlorophyll. Data files are an array on a 1-meter grid and combine both averaged CTD profile data, and bottle samples where depths with no data are listed as "-1E+10" in text data files, and as 1.0e-35 in NetCDF files. Data are available in two formats: netCDF, and Ocean Data View ASCII files. CTD data contacts: Phyllis Stabeno, Peggy Sullivan.

本导电率、温度、深度（CTD）数据集，包含242次投放，于2010年6月16日至7月13日在R/V Thompson（TN250）上进行的贝林海峡多学科冰航调查期间收集。此次航行由美国国家科学基金会（NSF）资助的贝林海峡生态系统研究-贝林海峡综合生态系统研究计划（BEST-BSIERP）资助，并得到众多机构与部门的支撑。BEST-BSIERP共同构成了贝林海峡项目。该航次中的CTD操作由美国国家海洋和大气管理局/海洋与环境实验室（NOAA/PMEL）的EcoFOCI项目人员管理，并得到Thompson船员的协助。投放的水样根据各研究团队的需求分别收集。CTD仪器获得的剖面数据在NOAA/PMEL/EcoFOCI使用标准化技术进行处理。瓶样数据包括磷酸盐、硅酸盐、硝酸盐、亚硝酸盐、铵和叶绿素。数据文件以1米网格排列，结合了平均CTD剖面数据和瓶样样本，在文本数据文件中，无数据深度以“-1E+10”表示，在NetCDF文件中以1.0e-35表示。数据以netCDF和Ocean Data View ASCII文件两种格式提供。CTD数据联系人：Phyllis Stabeno，Peggy Sullivan。营养和瓶样数据联系人：Calvin Mordy。注：数据已更新至2013年10月2日。
