Analyze these satellite images comparing Ocean Chlorophyll Concentrations with Sea Surface Temperatures beginning with the North Atlantic region, then expanding global patterns of these phenomena. Credit: NASA Earth Observatory
The world's ocean is heated at the surface by the sun, and this heating is uneven for many reasons. Earth's rotation, revolution around the sun, and tilt all play a role, as do the wind-driven ocean surface currents.This animation shows the long-term average sea surface temperature, with red and yellow depicting warmer waters and blue depicting colder waters.
Scientific data are often represented by assigning ranges of numbers to specific colors. The colors are then used to make false color images which allow us to see patterns more easily. Students will make a false-color image using a set of numbers.
Information from satellites if often used to display information about objects. This information can include how things appear, as well as their contents. Explore how pixel data sequences can be used to create an image and interpret it.
This NASA visualization shows sea surface salinity observations (September 2011-September 2014). Students review the video and answer questions.
Examine a model and answer questions about dust transport around the world.
Review this animation showing monthly average wind speed at 10 meters above the ocean surface for our global ocean (meters per second) in 2017-2018. This animation was created using the My NASA Data Earth System Data Explorer. For more information about how to create your own animation, see links at the bottom of this page.
Analyze the first of three graphs of historical ocean data in this series; this mini lesson features salinity values using the interactive tool, FlatMap, created by NASA's Aquarius Mission.
Students will make a claim about whether changing albedo contributes to changes in Arctic habitats.
