For over 20 years, satellite instruments have measured the sea surface height of our ever-changing oceans.  This video of images shows the complicated patterns of rising and falling ocean levels across the globe from 1993 to 2015.

Students analyze the stability and change of sea level after watching a visualization of sea level height around the world. 

Students analyze four data visualizations focused on the topic of sea level.  They use a jigsaw method to explore and communicate their findings to their peers.

Students examine the two time series images to determine the differences between seasonal ice melt over water versus land.

Students will watch a video on the Greenland Ice Sheet and answer questions.

This mini lesson helps students visualize how the Hydrosphere and Cryosphere interact to produce changes in land and sea ice. 

Students explore albedo, sea ice, and the relationship between changing albedo and changing sea ice using data visualizations. 

Arctic sea ice is the cap of frozen seawater blanketing most of the Arctic Ocean and neighboring seas in wintertime. It follows seasonal patterns of thickening and melting. Students view how the quantity has changed from 1979 through 2018. 

Students will use coloring sheets to create a color coded model of El Niño and analyze it. If the Data Literacy Map Cube is used with this, students will color their models first.

In this mini lesson, students use in-water profiles of historical ocean data to analyze how sea surface salinity varies with depth.
