BLACK MUD lO-IS CM OF BLACK MUD VERTICAL EXAGGERATION = lOx Fig. 12.—Profile of sand waves measured by divers. See Fig. 6 for location. On the side of a ridge, however, such a zone must be a "perched" deflation zone of fine gravel or coarse sand armoring fine sand, or simply the surface of a relatively thick deposit of coarse material. The tendency for such coarse zones to occur on the landward flank of ridges was observed in grain-size transects (Figs. 9, 11). The relatively erratic fluctua- tion of mean diameter in the transects of Fig. 9 becomes understandable when the complexity of small-scale grain-size patterns is observed on sidescan sonar (, F"ig. ISA). HYDRAULIC CLIMATE AND SUBSTRATE RESPONSE TO FLOW Offshore Flow Flow in the study area tends to be a slow northward drift. Our bottom-mounted Geo- dyne current meters revealed a mean flow of 10-15 cm/sec as measured within 37 cm of the bottom during two ten-tiay periods in July and August 1971 (see also Holliday, 1971). The flow was modulated by, but not generally reversed by, the semidiurnal tide. The north-.
