This 5-minute animation portrays fluctuations in the cryosphere through observations collected from a variety of satellite-based sensors. The cryosphere consists of those parts of the Earth's surface where water is found in solid form, including... (View More)

This self-paced, interactive tutorial explores how biological activity helps to determine vertical nutrient distributions in the ocean, examines why upwelling boosts marine productivity, and considers how various physical forces interact to... (View More)

This self-paced, interactive tutorial teaches how to estimate the travel time, acceleration, and trajectory of iceberg movement from satellite images. Factors that impact the complex motion of icebergs, such as weather, ice processes and... (View More)

This is an activity about how the Sun can affect the Earth's atmosphere, specifically the ionosphere. Learners will use real data from a Sudden Ionosphere Disturbance Monitor, or SID Monitor, to identify the signatures in the graphed data that can... (View More)

This is an activity about the Kp index, a quantification of fluctuations in the Earth's magnetic field due to the relative strength of a magnetic storm. Learners will take a reading from a magnetometer site and make a Kp index estimate to predict... (View More)
