havsnivåmätningar
Havsnivåmätningar refers to the process of measuring the height of the ocean's surface relative to a fixed reference point. This data is crucial for understanding climate change, coastal management, and navigation. Historically, measurements were taken manually using tide gauges installed at coastal locations. These gauges, often a simple float within a stilling well, would record tidal fluctuations and longer-term sea level trends.
In modern times, satellite altimetry has revolutionized havsnivåmätningar. Satellites equipped with radar altimeters send a signal
Tide gauges continue to provide valuable long-term, high-frequency data, especially for understanding regional variations and the
