. Collected reprints / Atlantic Oceanographic and Meteorological Laboratories [and] Pacific Oceanographic Laboratories. Oceanography the bottom (figs. 6 and 7) (Hersey, 1967). Cameras mounted in airplanes and satellites flying at elevations of hundreds of meters to hundreds of kilometers above sea level photograph areas encompassing thousands of square kilometers revealing major features of continental shelves such as submerged river deltas, islands, channels, and sand bars. Films sen- sitive to different portions of light spectrum reveal different features such as color variations and areas of abnormal heat on the con- tinental shelf and in the overlying seawater. Bottom Sampling The only exploration method that proves the presence of a particu- lar mineral deposit is sampling. Information obtained by sampling is limited to the precise spot sampled. For sampling to be effective, the sampling location must be closely delineated by the exploration methods or a sampling pattern employed suited to the anticipated size and sub- bottom depth of the deposit being & FLASH HOUSINC TRIPPING WEIGHT BOTTOM COVERAGE.
