TL;DR: In this article, a multi-reanalysis ensemble is used to estimate the signal-to-noise ratio (SNR) of the ocean state and to estimate uncertainty levels.

TL;DR: An overview of the development of satellite oceanography over the past five years focusing on the most relevant issues for operational oceanography can be found in this article, where a review of future missions shows clear progress and new research and development missions with a potentially large impact for oceanography should be demonstrated.

TL;DR: In this paper, the global and regional steric sea level changes are estimated and compared from an ensemble of 16 ocean reanalyses and 4 objective analyses, and the ensemble mean exhibits a significant high correlation at both a global and a regional scale.

TL;DR: In this paper, a comparison of the global ocean surface mixed layer depth (MLD) fields estimated from a suite of major ocean syntheses is conducted, and it is shown that the bias in the ensemble mean field of the reanalyses is smaller than in the observation-only analyses.

TL;DR: The work in this article summarizes climate variability as seen by several ocean syntheses, describes similarities and differences in these solutions and uses results to highlight developments necessary over the next decade to improve ocean products and services.
