NOAA National Centers for Environmental Information - formerly: National Geophysical Data Center

The demand for high-value environmental data and information has dramatically increased in recent years. To improve our ability to meet that demand, NOAA’s former three data centers—the National Climatic Data Center, the National Geophysical Data Center, and the National Oceanographic Data Center, which includes the National Coastal Data Development Center—have merged into the National Centers for Environmental Information (NCEI) https://www.re3data.org/repository/r3d100011801. The NOAA National Centers for Environmental Information (formerly the National Geophysical Data Center) provide scientific stewardship, products and services for sea floor and lakebed data, including geophysics (gravity, magnetics, seismic reflection, bathymetry, water column sonar), and data derived from sediment and rock samples. NCEI compiles coastal and global digital elevation models, high-resolution models for tsunami inundation studies, provides stewardship for NOS data supporting charts and navigation, and is the US national long-term archive for MGG data

近年来，对高价值环境数据与信息的渴求呈现出显著增长的趋势。为提升满足这一需求的能力，美国国家海洋与大气管理局（NOAA）原三个数据中心——国家气候数据中心、国家地球物理数据中心以及国家海洋数据中心（包括国家海岸数据发展中心）——已合并为美国国家环境信息中心（NCEI）。该中心，即原国家地球物理数据中心，负责对海底和湖底数据进行科学管理，并提供相关产品与服务，涵盖地球物理学（重力、磁力、地震反射、测深、水柱声纳）以及从沉积物和岩石样本中提取的数据。NCEI汇编沿海和全球数字高程模型，提供用于海啸淹没研究的超高分辨率模型，对支持海图和导航的NOS数据进行管理，并作为美国国家长期档案库存储MGG数据。https://www.re3data.org/repository/r3d100011801
