Vet further south, the Georgia Bight ex- periences a high tide range, a milder wave climate, and the closely spaced river mouths are estuarine in con- figuration. Their retreat has generated a blanket of coalescing shelf valley complexes (Fig. 16). Initiation of Modern Patterns TEXTL'RAL AND MORPHOLOGIC PATTERNS ON A STORM- shllf. On two of the best studied autoch- thonous shelves, the Middle Atlantic Bight of North America and the shelf around the British Isles, the hydraulic climate is sufficiently intense to overprint older subaerial and nearshore marine patterns of the surficial sand sheet with a modern textural and morpho- logic pattern. In the Middle Atlantic Bight fair-weather flows are driven by the geostrophic response of the stratified shelf water column to freshwater runoff and to winds (MeClenncn. 1973; Bumpus. 1973); see Fig. 17.
