Hoagland personal communication), are experienced rarel}- and then under only the most unusual of conditions in a confined area. The relative effect of river-borne detritus on nearshore trans- parency can be shown from measurements made near Oceanside, California, on February 21 and 22, 1958, two days following a major storm. There are 12 hydrographic stations in this area, each of which had been occupied 3 or 4 times prior to the February period. The average transparency in all seasons under no-storm conditions is shown in Plate 18, fig. A. The area of readings less than 30 feet has been cross-hatched and indicates a normal condi- tion of a band about one mile wide adjacent to the shore. As the streams flow intermittently there is no detectable effect of their flow on the transparency. Also, from 1956 through 1957 when these measurements were taken, rainfall was so minor that little debris reached the sea from the streams. In Plate 18, fig. B, the transparency pattern for February 21 and 22 is shown, and again the area where the disc readings of less.

The two distinct areas on the graph show the range of disc readings encountered under all conditions. The upper area shows that transparency near populated shores is normally less than along open coasts regardless of distance from shore. 80.
