World Ocean Database and World Ocean Atlas

The World Ocean Database (WOD) has global ocean observed and standard depth data profiles. The World Ocean Atlas (WOA) has objectively analyzed climatological mean fields on both a quarter-degree and on a one-degree longitude by latitude grids. The gridded analyses are for annual, seasonal, and monthly means of six oceanographic variables: temperature, salinity, dissolved oxygen, nitrate, phosphate, and silicate on standard levels (typically at 102 depths, dependent on data availability). The products were derived at the Ocean Climate Laboratory (OCL) of the National Oceanographic Data Center (NODC). Development of the World Ocean products began in 1982 and they have been updated in 1994, 1998, 2001, 2005, 2009, 2013, 2018 and 2023. The featured products are now based on the 2023 versions. Some products from older version are still unique. The WOD is the world's largest profile collection covering the global ocean and contains measurements from 1800 through 2023. The WOA are climatological grids at fixed depths derived from quality checked WOD profiles. This is a recognized world-wide standard and is often referenced in oceanographic research.

全球海洋数据库（World Ocean Database, WOD）收录全球海洋实测数据与标准深度数据剖面。全球海洋图集（World Ocean Atlas, WOA）则包含基于0.25度与1度经纬度网格的客观分析气候平均场。该网格分析产品涵盖温度、盐度、溶解氧、硝酸盐、磷酸盐与硅酸盐共6项海洋学变量的年、季、月平均数据，数据分布于标准深度层（通常设置102个深度层，具体数量取决于数据可获得性）。上述产品由美国国家海洋数据中心（National Oceanographic Data Center, NODC）下属的海洋气候实验室（Ocean Climate Laboratory, OCL）研发生成。
全球海洋系列产品的研发始于1982年，并分别于1994、1998、2001、2005、2009、2013、2018及2023年完成更新，当前主推产品均基于2023版本。部分旧版产品仍具备独特性。WOD是全球规模最大的海洋剖面数据集，覆盖全球海洋范围，收录了1800年至2023年间的观测数据。WOA是以经过质量质控的WOD剖面数据为基础生成的固定深度气候网格数据集，该产品已成为国际公认的海洋学行业标准，常被全球海洋学研究文献引用。
