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. See how the quantity has changed from 1979 through 2018.

The Earth's system is characterized by the interaction of processes that take place on molecular (very small) and planetary (very large) spatial scales, as well as on short and long time scales. Scientific visualizations allow us to experience Earth processes at faster speeds, and on manageable smaller scales, facilitating data analysis and enhancing understanding. Explore the visualizations below to see the new benchmark map scientists can use to study the extent and speed of changes to the largest ice sheet in the world.
Review the animation showing seasonal chlorophyll concentration as it relates to net radiation.
Conduct this EO Kids mini-lesson with your students to explore the phenomenon of Urban Heat Island Effect.
Why do you think grass feels cooler than pavement? And how are materials in a city different from those you find in rural and wild areas? The answer is that the materials in our neighborhoods retain, absorb, and radiate heat differently.
Students observe images of daily average sea surface temperatures taken during 2017, as they analyze the plots for evidence of changes that are occurring throughout the year.
