 Zusammenfassung: Tide gauges can capture sea level variability on multiple timescales, from high frequency events like waves, tides and tsunamis, to seasonal and interannual changes and the longer-term trends associated with Climate Change. However, tide gauges are costly to maintain to the stringent accuracy requirements demanded by the IOC-UNESCO’s Global Sea Level Observing System (GLOSS) for monitoring sea level rise. As a result, they are often maintained to lower accuracy standards, for example, where their primary purpose is for short-term operational forecasting. This diminishes the supply of suitable sea level data for scientific studies. In addition, a sparsity of Global Navigation Satellite System (GNSS) receivers at the coast leads to large uncertainties in rates of land motion at tide gauges, which also hampers the estimation of long-term sea level trends. Through the Horizon Europe EuroSea project and the National Oceanography Centre’s (NOC) UK Tide Gauge project, we have devised prototype low-cost and largely maintenance-free tide gauge systems, which can be powered by renewable energy and which monitor both land motion and sea level using novel techniques such as ground-based GNSS Interferometric Reflectometry (GNSS-IR). These systems eliminate the need for costly ongoing levelling exercises and also incorporate customisations to local monitoring needs, such as sensors for lightning detection and wave height. The systems are being tested in a variety of coastal environments, including the UK, the Mediterranean Sea and South America. It is hoped that there is potential to advance these technological solutions as a global standard, via the GLOSS community.
