Other environmental factors such as atmospheric conditions, sun and viewing angles, surface Winds, and waves also influence the measure- ment of ocean color. Figure 10 shows surface measure- ments of upwelling spectra from three types of water masses and il- lustrates the increase in energy in the green and red regimes of the spectrum as the transition "from Gulf Stream to estuarine water is made [Maul and Gordon, 1975]. Figure 11 is a computer-enhanced Landsat image of a 140 x 140 km2 sector of the New York Bight, show- ing suspended sediments from the Hudson River, acid-dumping events, water mass variations, and internal waves, the last being visible because of the sun glint [Apel et al, 1975]. Ocean color. The CZCS on Nim- bus-G will image the ocean surface and near-surface in multiple wavelengths of visible light and reflected and thermal infrared radiation with 800-m spatial resolu- tion over swath widths of 700 km under controlled illumination condi- tions; the observation interval will be 1-6 days. The choice of wavelength bands was dictated by the requirement for making quan- titative measurements relating to chlorophyll and sediment concen- trations (W. Hovis, private com- munication, 1976). Measurement of ocean color from radiometric quality imagery of the desired area in several spectral in- tervals will perhaps allow measure- ment, at least under certain limited conditions, of the following features: suspended near-surface sediment distribution and concentration; chlorophyll distribution and concen- tration between perhaps and 20 mg/m3 (W. Hovis, private com- munication, 1976); fish stock loca- tion via relationship to biosignifi- cant observables [Stevenson et al., 1973]; and pollutant distribution and concentration [Wezernak and Fig.
