The rate of global sea level rise has been accelerating in recent decades, rather than increasing steadily, according to a new study based on 25 years of NASA and European satellite data.
Hydrosphere - Maps & Data
My NASA Data (MND) provides online resources to help teachers and students access NASA data in a variety of formats. MND offers pre-generated graphs, mapped visualizations, animations, and processed data based on NGSS phenomena, providing the learner with the opportunity to explore concepts without being encumbered by visualization interfaces. These flexible resources provide guiding questions and other teacher tools so you can use them to open or close your class activity.

Featured Phenomenon: Sea Level Change
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.
Rising Seas By Decade
For over 20 years, satellite altimeters have measured the sea surface height of our ever-changing oceans. This series of images shows the complicated patterns of rising and falling ocean levels across the globe from 1993 to 2015.
Sea Level Rise
Students explore the effects of ice sheets on global sea level focused using NASA data. Using the resources provided, students collaborate and communicate their findings in a jig-saw activity format.
Stability and Change: Monitoring Sea Level
The Earth's system exemplifies stability and change. Change and rates of change can be observed and quantified over very short or long periods of time and various spatial scales (e.g., from landscape level to global processes).
A Map of Freshwater
Freshwater is found in lakes, rivers, soil, snow, groundwater and ice, and is one of the most essential of Earth's resources, for drinking water and agriculture. However, the distribution of freshwater around the planet is changing.

“Sea level scientists have a pretty good grasp on global mean sea level,” said Steve Nerem, a professor in the Aerospace Engineering Sciences Department at the University of Colorado and the team leader for NASA’s Sea Level Change Team (N-SLCT).
