Tiny plants called phytoplankton grow in the sunlit waters of the ocean's surface. Like all plants, phytoplankton contain chlorophyll, a pigment that transforms sunlight into energy the plant can use. This same pigment gives phytoplankton their greenish color.
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.
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.
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.
