The development of multispectral scanners flown on aircraft and satellites have led to the use of these for measuring ocean color remotely. Potentially, this remote sensing of color will substantially increase the oceanographer's ability to monitor chlorophyll and particulate concentration in the upper layers over large spatial areas. Research conducted over the past several years has developed the techniques and laid the ground work for the quantitative interpretation of the remote sensed signals. It has been shown the meaningful corrections to these signals for atmospheric scattering can be made and that the resultant inherent signal can be correlated with in-situ measurements of chlorophyll and particulate matter concentration. A review of these experiments and techniques is presented.
