tengervízszintet

Tengervízszint refers to the average level of the ocean's surface. It is a dynamic measurement influenced by various factors, including tides, atmospheric pressure, and ocean currents. While tides cause daily fluctuations, longer-term changes in sea level are primarily driven by global phenomena.

The most significant driver of long-term sea level change is thermal expansion of seawater. As the Earth's temperature rises due to climate change, the oceans absorb heat, causing the water to expand and occupy more volume. Another major contributor is the melting of glaciers and ice sheets located on land, such as those in Greenland and Antarctica. The water from these melting ice masses flows into the oceans, increasing the total volume of water.

Monitoring tengervízszint is crucial for understanding the impacts of climate change. Rising sea levels pose significant threats to coastal communities, increasing the risk of flooding, erosion, and saltwater intrusion into freshwater sources. Scientists use a variety of methods to measure sea level, including tide gauges, satellite altimetry, and oceanographic data. These measurements provide valuable information for predicting future sea level changes and developing adaptation strategies. Understanding the complex factors that influence tengervízszint is essential for both scientific research and practical coastal management.
