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.
Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the https://makedatacount.org/ project. If journals do not provide citation information to these publicly-accessible services, then this citation information will not be included in RDA citation counts. Additionally citations that include dataset DOIs are the only types included in these counts, so legacy citations without DOIs, references found in publication acknowledgements, or references to a related publication that describes a dataset will not be included in these counts.
