Learn more about the different causes of sea level change and the scientific background of observations and projecting sea level. Find out about the history of measuring sea level and how state-of-the-art physical climate models predict sea level change into the future.
Students explore the effects of ice sheets on global sea level using NASA data. Using the resources provided, students collaborate and communicate their findings in a jig-saw activity format.
This learning activity uses data acquired by the TOPEX/Poseidon altimeter, a joint project of NASA and the French Space Agency, to investigate the relationship between the topography of a sea-floor feature and the topography of the overlying sea surface.
Sea Level Scientists are also known by several other names (marine geologist, paleoceanographer, paleoclimatologist, etc.). These professionals use natural records from the past to characterize local, regional, and global environments.
Two characteristics of climate change are resulting in sea level rise. First, the melting of ice sheets and glaciers on land are adding more water to the oceans.
Hydrosphere: Water participates in many important natural chemical reactions and is a good solvent.
In some parts of the world sea levels are increasing, while decreasing in others, and remain relatively flat in a few places; for more than 20 years, NASA has been tracking the global surface topography of the ocean to understand the important role it plays in our daily lives.

Global sea level rise has been accelerating in recent decades, according to a new study based on 25 years of NASA and European satellite data.
