Real-Time XBT Data assembled by US NOAA Atlantic Oceanographic Meteorological Laboratory (AOML) for the Global Temperature-Salinity Profile Program (GTSPP) and submitted 03/31/2008 - 04/06/2008 (NODC Accession 0040146)

These data represent data collected from the Shipboard Environmental (data) Acquisition System (SEAS), a program developed by National Oceanic and Atmospheric Administration (NOAA) to provide accurate meteorological and oceanographic data in real time from ships at sea through the use of satellite data transmission techniques. The system transmits data through either the Geostationary Operational Environmental Satellite (GOES) or the International Maritime Satellite Organization (INMARSAT C) satellites to NOAA for use in weather, climatological and ocean models. NOAA is actively participating in an international effort to increase the number of subsurface temperature observations in support of global oceanographic and climate studies. NOAA's Expendable Bathythermograph (XBT) program, SEAS, currently supports about 80 Voluntary Observing Ships (VOS). SEAS XBT data are archived by the National Oceanographic Data Center (NODC) on a weekly basis.

本数据集采集自船载环境数据采集系统（Shipboard Environmental Data Acquisition System，缩写SEAS）。该系统由美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration，缩写NOAA）研发，旨在通过卫星数据传输技术，实时获取海上船舶传回的高精度气象与海洋学数据。系统可通过地球静止业务环境卫星（Geostationary Operational Environmental Satellite，缩写GOES）或国际海事卫星组织（International Maritime Satellite Organization，INMARSAT）C频段卫星传输数据至美国国家海洋和大气管理局，供气象、气候与海洋学模型研究使用。美国国家海洋和大气管理局正积极参与一项国际协作计划，以扩大水下温度观测数据的采集规模，支撑全球海洋学与气候研究工作。美国国家海洋和大气管理局的投弃式温深仪（Expendable Bathythermograph，缩写XBT）项目即船载环境数据采集系统，目前可支持约80艘志愿观测船（Voluntary Observing Ships，缩写VOS）开展观测作业。船载环境数据采集系统的投弃式温深仪数据由国家海洋数据中心（National Oceanographic Data Center，缩写NODC）按周进行归档存储。
