STS040-152-99 & STS040-152-100 Bi-Directional Reflectance of San
Francisco Bay. When bi-directional reflectance techniques are
used, glare from the water's surface is masked. Differences in
sediment quality and distribution can be seen more easily. Ef-
fluent produced by agricultural areas to the north is visible as
the darker colored water.

Although clouds obscure part of the city of San Francisco and the mouth of the Bay (37.5N, 122.0W), many cultural and natural features in the immediate vicinity are obvious. The Bay Bridge which was damaged in the 1989 earthquake, Candlestick Park, San Mateo and Dumbarton Bridges as well as the various colored settling ponds rimming the south end of the Bay, the San Andreas and Calaveras faults and many of the major highways can be seen.
