Low resolution real-time physical trajectory profile data from glider sylvia deployed by Virginia Institute of Marine Science (VIMS) in the Mid-Atlantic Bight from 2021-08-27 to 2021-09-10 (NCEI Accession 0246776)

This project supports the deployment and realtime data delivery of autonomous underwater gliders in the coastal ocean to better resolve and understand essential ocean features and processes that contribute to hurricane intensification or weakening prior to making landfall. This is a partnership between NOAA Ocean and Atmospheric Research (OAR) through the Atlantic Oceanographic and Meteorological Laboratory (AOML) and Integrated Ocean Observing System (IOOS) regional associations such as MARACOOS, SECOORA, CariCOOS and institutions including the University of Puerto Rico, University of the Virgin Islands, Skidaway Institute of Oceanography, University of Delaware, Virginia Institute of Marine Science - William & Mary, and Rutgers University. The goal of the project is to provide realtime data for ocean model validation and assimilation throughout hurricane season. This project is supported by the Disaster Recovery Act. The glider will survey the outershelf and shelfbreak region between Baltimore Canyon and Cape Hatteras.

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.

本项工程旨在支持自主水下滑翔艇在近海区域的部署与实时数据传输，以更深入地解析和理解海洋基本特征及其过程，这些特征和过程对于飓风的增强或减弱至关重要，尤其是在登陆前。该项目由美国国家海洋和大气研究局（NOAA OAR）下属的大西洋海洋与气象实验室（AOML）以及综合海洋观测系统（IOOS）区域协会，如MARACOOS、SECOORA、CariCOOS等，以及包括波多黎各大学、维尔京群岛大学、斯凯德韦海洋研究所、特拉华大学、弗吉尼亚海洋科学学院威廉与玛丽学院和罗格斯大学等机构共同合作实施。项目目标在于为整个飓风季节提供实时数据，以验证和同化海洋模型。该项目得到了灾害恢复法案的支持。滑翔艇将对巴尔的摩海峡与哈特拉斯角之间的外大陆架和大陆架边缘区域进行勘察。国家环境信息中心（NCEI）从综合海洋观测系统国家滑翔艇数据汇编中心（IOOS NGDAC）接收了该数据集中的数据。IOOS NGDAC接收到的数据包含一个或多个netCDF文件，这些文件构成了整个滑翔艇部署的全部。数据是关于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，将文件汇总成一个单一的netCDF文件，并将其提交给NCEI进行长期保存。数据文件可以是低分辨率实时数据或全分辨率数据。全分辨率文件在netCDF文件名中被标识为“延迟”数据。
