Real-Time XBT Data assembled by US NOAA Atlantic Oceanographic Meteorological Laboratory (AOML) for the Global Temperature-Salinity Profile Program (GTSPP) and submitted 06/16/2008 - 06/22/2008 (NODC Accession 0042951)

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）开发，旨在借助卫星数据传输技术，实时获取远洋船舶的精准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频段卫星，将观测数据回传至美国国家海洋和大气管理局，以供气象、气候及海洋数值模式研究使用。
美国国家海洋和大气管理局正积极参与一项国际合作计划，以扩充次表层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。其旗下的投弃式海温剖面仪（Expendable Bathythermograph，XBT）项目与船载环境（数据）采集系统目前可支持约80艘志愿观测船（Voluntary Observing Ships，VOS）开展观测作业。船载环境（数据）采集系统的投弃式海温剖面仪观测数据，由国家海洋数据中心（National Oceanographic Data Center，NODC）按周进行归档存储。
