[27-July-16] At NASA's Goddard Space Flight Center Science Jamboree, Aimee Neeley demonstrates an ocean color activity to a participant. The "Little Bits" activity includes instructions for constructing a simple spectrophotometer and measuring different colors of water to observe their spectral differences. Green water is used to represent spectra of more productive water (i.e., high in chlorophyll) and the red/orange water represents water high in dissolved organic materials such as leaves or bark.
