We often take the Biosphere for granted and as the climate changes, plant species and ecosystems respond by adapting, migrating or reducing their population. Why is this important? The plants of the Biosphere feed us, clothe us, absorb carbon dioxide, provide us with oxygen,
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.
The Earth's system exemplifies stability and change. Change and rates of change can be observed and quantified over very short or long periods of time and at various spatial scales (e.g., from landscape level to global processes).
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.
Scientific data are often represented by assigning ranges of numbers to specific colors. The colors are then used to make an 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.
Visualize NASA data on a custom map using our Earth System Data Explorer to generate your own maps and graphs. See the Dataset in LAS to see the range of datasets supporting this phenomenon.
Students explore the seasonal differences of vegetation found on land and sea.
Explore using units in calculations with the Leaf Area Index (LAI). LAI is a ratio that describes the number of square meters of leaves per square meter of available land surface. Because of the units in the ratio, it is dimensionless.
