Performance of modern tide gauges: towards the mm-level accuracy
International audience Considerable efforts are being made worldwide to upgrade tide gauge networks using new technologies. Because of the unique location of the Kerguelen Islands, the measurement of sea level there has received particular attention, with up to four systems equipped with modern sens...

International audience Considerable efforts are being made worldwide to upgrade tide gauge networks using new technologies.
