The pathlines are the location of the 22° C isotherm at 100 meters depth for September 27-28, 1972 and November 2-3, 1972. These cruises were made at 36 day intervals, in synchronization with every other ERTS transect (after Maul, 1975). suspended or dissolved in a medium with only poorly known optical properties. Lack of knowledge of the optical para- meters affecting reflectance must be overcome before significant progress can be made. Satellite Observations Several examples of LANDSAT-1 observations of the Gulf Stream system are given in Figs. 13, 14, and 15. The location of each of these images is given in Fig. 11, which also includes pathlines of the 22°C isotherm at 100 meters depth made during satellite transit. As noted before, this isotherm is generally 'V 14 (la = ±10) kilometers to the left (facing upstream) of the cyclonic edge, but has significant variability about this mean value due to surface winds, curva- ture in the current, and current speed. It is seen that significant variability exists in these pathlines, only 36 days apart, which emphasizes the need for synop- icity in oceanographic baseline measure- ments for remote sensing. Diffuse reflectance from beneath the ocean is rarely more than (cf., inset to Fig. 1). Reflectance from the ocean's surface, which is independent of this 509.
