Absolute Versus Relative Sea Level

Earth's long-term climate changes have been dominated by the ice age cycles. The long cool periods (glacials) cause the ice sheet gain, mostly in high latitude areas, and the shorter, warmer periods (interglacials) cause the ice melting along with water expansion due to the water volume increase. Recent studies revealed that several human-induced climate drivers contribute to the current global warming in addition to the natural climate drivers. The global sea level change is one of the most certain consequences of the climate change. As the sea level significantly influences the human, animal, and plant life and habitats, especially in the coastal areas, and as it is used in wide variety of research disciplines, monitoring of the sea level change is of fundamental importance. Therefore, the sea level data are marked as the highest priority within the global scientific initiative on climate change led by The Intergovernmental Panel on Climate Change (IPCC). This study reports on the different approaches to delivering the absolute sea level at tide gauges, combining the altimeter and tide gauge data, and future projects that are expected to improve the sea level measurements.
