Real-Time XBT Data assembled by US NOAA Atlantic Oceanographic Meteorological Laboratory (AOML) for the Global Temperature-Salinity Profile Program (GTSPP) and submitted 05/12/2008 - 05/18/2008 (NODC Accession 0042188)

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.

本数据集的数据源自船载环境数据采集系统（Shipboard Environmental (data) Acquisition System, SEAS）——该项目由美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）研发，旨在通过卫星数据传输技术，实时获取海上船舶的高精度气象与海洋水文数据。该系统通过地球静止业务环境卫星（Geostationary Operational Environmental Satellite, GOES）或国际海事卫星组织（International Maritime Satellite Organization, INMARSAT C）将数据回传至NOAA，供气象、气候及海洋模型研究使用。NOAA正积极参与一项国际协作计划，以扩充水下温度观测数据的采集规模，为全球海洋与气候研究提供支撑。NOAA的投弃式温深仪（Expendable Bathythermograph, XBT）项目与SEAS系统目前可为约80艘志愿观测船（Voluntary Observing Ship, VOS）提供观测支持。SEAS系统的XBT观测数据由国家海洋数据中心（National Oceanographic Data Center, NODC）按周进行归档存储。
