World Ocean Atlas 2023 Figures

WOA23 Figures application contains geographic distributions of objectively analyzed fields and statistics at 102 standard depth levels of the World Ocean. Temperature and salinity fields are available on one-degree and quarter-degree latitude-longitude grids and were generated for the following time periods: 1955-1964, 1965-1974, 1975-1984, 1985-1994, 1995-2004, 2005-2014, 2015-2022 and three 30-year 'climate normal' periods: 1971-2000, 1981-2010, and 1991-2020. Inorganic nutrients (phosphate, silicate, and nitrate) are presented on one-degree fields for the 1965-2022 time period. Oxygen, Apparent Oxygen Utilization, and Percent Oxygen Saturation are presented on one-degree fields for the 1965-2022 and 1971-2000 time periods.

The fields used to generate these climatological maps were computed by objective analysis of all scientifically quality-controlled historical data in the World Ocean Database 2023.

Visually impaired users can use the World Ocean Atlas 2023 Data application for accessible versions of this data.
