TN250-10 CTD and Nutrient Data. Version 1.0

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. Nutrient and bottle data contact: Calvin Mordy. Note: Data have been updated as of 02 Oct 2013.

本数据集为电导率-温度-深度（Conductivity Temperature Depth, CTD）数据集，包含242个CTD测站剖面数据，采集自2010年6月16日至7月13日期间“汤普森号”（R/V Thompson, 航次编号TN250）开展的白令海海冰多学科考察航次。本航次由美国国家科学基金会（National Science Foundation, NSF）资助的白令海生态研究-白令海综合生态系统研究计划（BEST-BSIERP）立项，得到了多家机构与单位的支持，BEST-BSIERP整体即为白令海研究项目。本次航次的CTD作业由美国国家海洋和大气管理局太平洋海洋环境实验室（NOAA/PMEL）下属生态系统与渔业海洋学协调调查计划（EcoFOCI）的人员负责管理，“汤普森号”机组人员协助开展设备布放工作。各研究团队根据自身科研需求，采集了各测站的水样。CTD仪器获取的剖面数据由NOAA/PMEL/EcoFOCI采用标准处理流程完成整编。水样瓶采样得到的检测数据涵盖磷酸盐、硅酸盐、硝酸盐、亚硝酸盐、铵盐以及叶绿素含量。数据集文件以1米分辨率网格为基准进行组织，整合了平均CTD剖面数据与水样瓶采样数据；对于无有效数据的深度层，文本数据文件中以“-1E+10”标记，NetCDF格式文件中则以1.0e-35标记。本数据集提供两种格式的文件：NetCDF格式以及海洋数据查看器（Ocean Data View）ASCII格式文件。CTD数据联系人：Phyllis Stabeno、Peggy Sullivan。营养盐与水样瓶采样数据联系人：Calvin Mordy。备注：本数据集最后更新于2013年10月2日。
