TL;DR: The Copernicus Marine Environment Monitoring Service (CMEMS) Ocean State Report (OSR) provides an annual report of the state of the global ocean and European regional seas for policy and decision-makers with the additional aim of increasing general public awareness about the status of, and changes in, the marine environment as mentioned in this paper.

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: The Journal of Operational Oceanography Volume 12 Supplement 1 August 2019 as mentioned in this paper has published a survey of trends over the past decades in the field of oceanography, including anomalies and extreme events.

TL;DR: The Copernicus in situ ocean dataset of temperature and salinity (version 5.2) is presented in this article, and an objective analysis-based method is developed to assess the quality of the dataset validation process.

Abstract: . We present a binned product of sea surface temperature, sea surface salinity, and sea surface density data in the North Atlantic subpolar gyre from 1993 to 2017 that resolves seasonal variability along specific ship routes ( https://doi.org/10.6096/SSS-BIN-NASG ). The characteristics of this product are described and validated through comparisons to other monthly products. Data presented in this work were collected in regions crossed by two predetermined ship transects, between Denmark and western Greenland (AX01) and between Iceland, Newfoundland, and the northeastern USA (AX02). The data were binned along a selected usable transect. The analysis and the strong correlation between successive seasons indicate that in large parts of the subpolar gyre, the binning approach is robust and resolves the seasonal timescales, in particular after 1997 and in regions away from the continental shelf. Prior to 2002, there was no winter sampling over the West Greenland Shelf. Variability in sea surface salinity increases towards Newfoundland south of 54 ∘ N, as well as in the western Iceland Basin along 59 ∘ N. Variability in sea surface temperature presents less spatial structure with an increase westward and towards Newfoundland. The contribution of temperature variability to density dominates in the eastern part of the gyre, whereas the contribution of salinity variability dominates in the southwestern part along AX02.
