Metadata: Yearly estimates of near-global ocean heat content and thermosteric sea level between 1970 - 2023, depth-integrated over upper ocean (0-700 m) for 65N-65S
Abstract:
This dataset provides yearly estimates of near-global (65N-65S) ocean heat content and thermosteric sea-level depth-integrated for the upper 700 meters of the ocean for 1970 - 2023. The yearly values are presented with three-year smoothing and one-sigma error estimates. The dataset builds upon and updates the methodology established in Domingues et al. (2008, Nature), incorporating temperature measurements from ocean observation systems and applying corrections for instrumental biases and sampling irregularities. To estimate ocean heat content for the upper 700 m and the associated thermosteric sea level, we used ocean temperature profiles from the ENACT/ENSEMBLES version 3 (EN3) data set (1970-2004), and Argo/Ifremer profiling floats (2000-2023, updated January 2024). Empirical Orthogonal Functions (EOFs) were used to model variability of the time-varying sea level and were calculated from 23 years (1993–2015) of satellite altimeter data sourced from Commonwealth Scientific and Industrial Research Organisation (CSIRO), (TOPEX/Poseidon, Jason-1, Jason-2 and Jason-3).

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | This dataset was created by the organisations with the "originator" role in this metadata record following their in-house data processing and quality control procedures. The data were then provided to the British Oceanographic Data Centre (BODC) for long-term archive and data publication in the BODC Published Data Library |
