Real-time sea-level gauge observations and operational oceanography
Theme issue ‘Sea level science’.-- 18 pages, 11 figures The contribution of tide-gauge data, which provide a unique monitoring of sea-level variability along the coasts of the world ocean, to operational oceanography is discussed in this paper.
