Physical trajectory profile data from glider ru29 deployed by Rutgers, the State University of New Jersey in the South Atlantic Ocean from 2015-06-23 to 2016-03-31 (NCEI Accession 0154378)

Third leg of the ru29 Challenger mission from Brazil to South Africa. The Challenger Mission is a re-creation of the first global scientific ocean survey conducted by the HMS Challenger in 1872. A fleet of up to 16 autonomous underwater gliders will be deployed in all five ocean basins. The goals of the project are the spread ocean literacy, educate the general population about the ocean's impact on global climate and provide real-time temperature, salinity and density profiles for assimilation into regional and global weather forecasting models. The National Centers for Environmental Information (NCEI) received the data in this archival package from the Integrated Ocean Observing System's National Glider Data Assembly Center (IOOS NGDAC). The IOOS NGDAC received the data in one or more netCDF files comprising an entire glider deployment. The data are measurements of physical oceanographic properties such as temperature, salinity, conductivity, and density. The IOOS NGDAC checked the files for compliance to their netCDF file convention, aggregated the files into a single netCDF file, and then submitted the file to NCEI for long-term preservation.ru29挑战者任务的第三航段，航程从巴西至南非。挑战者任务是对1872年英国皇家海军挑战者号（HMS Challenger）开展的全球首次系统性海洋科学考察的复刻项目。本次任务将部署最多16台自主水下滑翔机（autonomous underwater gliders），作业范围覆盖全球全部五大洋盆。本项目的核心目标包括：普及海洋科学素养，向公众科普海洋对全球气候的影响，以及提供实时温度、盐度与密度剖面数据，以供区域及全球天气预报模型开展数据同化。 国家环境信息中心（National Centers for Environmental Information, NCEI）从集成海洋观测系统国家滑翔机数据汇编中心（Integrated Ocean Observing System's National Glider Data Assembly Center, IOOS NGDAC）处获取了本归档数据包中的全部数据。IOOS NGDAC从覆盖整套滑翔机部署任务的一个或多个netCDF格式文件中获取原始数据。本数据集包含温度、盐度、电导率与密度等物理海洋学参数的实测值。IOOS NGDAC会对所有文件进行netCDF文件规范符合性校验，将多个文件整合为单个netCDF文件后，提交至NCEI进行长期归档保存。
