Low resolution real-time physical trajectory profile data from glider ru29 deployed by Rutgers, The State University of New Jersey; Center for Ocean Observing Leadership (RU COOL) in the Caribbean Sea from 2020-09-08 to 2020-11-16 (NCEI Accession 0276744)

The Challenger Glider Mission is a re-creation of the first global scientific ocean survey conducted by the HMS Challenger from 1872-1876. The goals of the mission are to establish a collaborative international network of autonomous underwater glider ports, to assess global ocean model predictive skill while contributing real-time profile data for assimilation in ocean forecast models by operational centers worldwide, and to crowd source student-based ocean research and discovery. Glider is providing temperature, conductivity, salinity, density and current profile observations. The current profiles are logged via external pd0 files and are not available in this real-time dataset. RU29 is flying in the vicinity of the Anegada Passage and throughout the surrounding island regions to monitor heat transport between the Caribbean Sea and the Tropical North Atlantic. This region includes the US Virgin Islands, British Virgin Islands, and Anguilla, areas commonly impacted by tropical cyclones. This real-time data set contains CTD, chlorophyll, CDOM, beta700nm and ADCP measurements.

The National Centers for Environmental Information (NCEI) received the data in this dataset 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. Data files may be either low resolution real-time or full resolution. Full resolution files are designated as "delayed" in the netCDF file name.

挑战者号滑翔机任务是对1872年至1876年间由HMS挑战者号执行的首次全球科学海洋调查的再现。该任务的宗旨在于建立一个由自主水下滑翔机港口组成的国际合作网络，评估全球海洋模型预测能力，同时为全球各地的运营中心提供实时剖面数据以供海洋预报模型同化，并促进基于学生的海洋研究和发现。滑翔机提供了温度、电导率、盐度、密度和流速剖面观测数据。当前流速剖面通过外部pd0文件记录，并不包含在此实时数据集中。RU29号滑翔机在安尼加达海峡及其周边岛屿区域飞行，以监测加勒比海与热带北大西洋之间的热量传输。该区域包括美属维尔京群岛、英属维尔京群岛和安圭拉，这些地区常受热带气旋的影响。此实时数据集包含CTD、叶绿素、CDOM、beta700nm和ADCP测量数据。

国家环境信息中心（NCEI）从综合海洋观测系统国家滑翔机数据汇编中心（IOOS NGDAC）接收了本数据集中的数据。IOOS NGDAC接收到的数据存储在一个或多个包含整个滑翔机部署的netCDF文件中。这些数据是物理海洋学特性的测量，如温度、盐度、电导率和密度。IOOS NGDAC检查了文件是否符合其netCDF文件规范，将文件汇总为单个netCDF文件，然后将文件提交给NCEI进行长期保存。数据文件可能是低分辨率实时数据或全分辨率数据。全分辨率文件在netCDF文件名中被标记为“延迟”。
