Meeresspiegelshöhe

Meeresspiegelshöhe refers to the average height of the Earth's oceans relative to a reference point, often sea level. This measurement is crucial for understanding global climate patterns, coastal erosion, and the impact of rising sea levels due to climate change. Historically, sea level has fluctuated due to factors like glacial melt and geological shifts.

Modern measurements of Meeresspiegelshöhe are taken using tide gauges located along coastlines and, more recently, satellite altimetry. Satellite data provides a more comprehensive and accurate global picture. The average global sea level has been observed to be rising at an accelerating rate, primarily attributed to thermal expansion of seawater as it warms and the melting of glaciers and ice sheets.

Changes in Meeresspiegelshöhe have significant consequences. Coastal communities face increased risks of flooding, saltwater intrusion into freshwater sources, and erosion. These changes also impact marine ecosystems, affecting habitats and species distribution. Monitoring and projecting future Meeresspiegelshöhe are therefore vital for adaptation and mitigation strategies in the face of global warming.
