Sea level research is a field of study that focuses on understanding and monitoring changes in the average height of the world's oceans over time. This research includes measuring sea level rise and fall, studying the causes of these changes (such as melting ice caps and thermal expansion of seawater), and predicting future sea level trends. Scientists use a variety of methods, including satellite observations, tide gauge measurements, and computer modeling, to track and analyze variations in sea level around the globe. This research is important for understanding the impacts of climate change on coastal communities, ecosystems, and infrastructure.
