NCEI ocean heat content, temperature anomalies, salinity anomalies, thermosteric sea level anomalies, halosteric sea level anomalies, and total steric sea level anomalies from 1955 to present calculated from in situ oceanographic subsurface profile data (NCEI Accession 0164586)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 29, 2026 | Last Modified: 2025-09-12T00:00:00.000+00:00
This dataset contains ocean heat content change, oceanic temperature and salinity changes, and steric sea level change (change in volume without change in mass), which are important variables for monitoring the oceanic environment and by extension the Earth's energy and freshwater budgets. NCEI, as the repository for oceanic subsurface profile data, especially for temperature and salinity profiles, has the data to calculate historic and recent changes in the above mentioned ocean variables. Data gathered from the NCEI archives, uniformly formatted and quality controlled in the World Ocean Database, are used to calculate temperature (and salinity) differences from a long-term climatological mean (the World Ocean Atlas series) at specific depth levels. These anomalies are used to derive integrals of ocean heat content and means for all other variables listed above.
