Fire is a powerful force on our planet. From South America's rainforests to Africa's savannas and Australia's highlands, fires touch 30 percent of the land surface. Yet whether naturally occurring or set by humans, fires' effects reach far beyond ravaged lands.
Identifying cause and effect relationships can help us make predictions about the function of natural systems and their impact on the world. These relationships, whether simple or complex, are vital for forecasting weather and predicting Earth events in new contexts.
Carbon dioxide concentration in the atmosphere is affected, among other things, by processes involving forests including fires, deforestation and plant respiration. Evaluate a Landsat image to determine the rate of carbon dioxide sequestration in a particular area.
The Sea-Viewing Wide Field-of-View Sensor (SeaWiFS) instrument aboard the Seastar satellite collected ocean data for more than a decade.
Turbulent storms churn the ocean in winter, adding nutrients to sunlit waters near the surface. Each spring this gives rise to massive blooms of phytoplankton. These microscopic plants harvest vital energy from sunlight through photosynthesis.
An ultra-high-resolution NASA computer model has given scientists a stunning new look at how carbon dioxide in the Atmosphere travels around the globe. Plumes of carbon dioxide in the simulation swirl and shift as winds disperse the greenhouse gas away from its sources.
