b. Shoreface. The term shoreface describes the nearshore area of the shelf extending 

 seaward from the shore to a depth where bottom slope markedly changes to a lower grade. 

 Depth of the shoreface base in the survey area is about 30 to 35 feet. South of Canaveral 

 Harbor the shoreface is regular with a width of nearly 1 ,500 yards and the base defined by a 

 gentle change of slope at about 30 feet. Average shoreface slope in this area is 1 on 150; just 

 north of Canaveral harbor the slope is similar but the break Ues at about 25 feet. 



Interrupting the configuration of the shoreface as it trends east and north paralleling the 

 coastline around Cape Canaveral is Southeast Shoal, extending from Cape Canaveral, and 

 Chester Shoal, extending from False Cape. Between these features the shoreface has a gentle 

 slope (1 on 250) and is nearly 2,500 yards wide. Southeast and Chester Shoals are 

 shore-connected shoals (Fig. 4); they merge into the shoreface zone and are an integral part 

 of the bottom morphology seaward of the shore. The tips of both southeasterly trending 

 shoals have a northeast orientation. 



Southeast Shoal is larger, more regular in plan view and more symetrical in cross section 

 than Chester Shoal. The shallowest part of Southeast Shoal fringes the shore, while high 

 parts of Chester Shoal are separated from the shore by a 30-foot slough. (See Figure 5.) 



North of Chester Shoal a series of shoreface-tied linear shoals (A, B, and C, Fig. 5) extend 

 north-northeast from the shoreface. The shoals are parallel, have similar shapes and depths 

 (18-foot crest), and display a progressive stage of separation and isolation from the 

 shoreface. The shoreface gradually deepens north of Chester Shoal from —40 feet 

 immediately north of Shoal C, to —50 feet at the north end of Mosquito Lagoon, to —60 

 feet just south of Ponce de Leon Inlet. Widths are 1,200, 1,500, and 3,000 yards at these 

 three locations with slopes of 1 on 90, 1 on 90, and 1 on 180, respectively. 



c. Shoal Region. Morphology of the sea floor in Cape Canaveral grid is dominated by 

 isolated shoals rising to depths of 15 to 25 feet below MLW from a base at 40 to 50 feet 

 MLW. These shoals (The Bull, Ohio Shoal, Hetzel Shoal, and Shoals D and E) he seaward of 

 the large cape shoals. (See Figure 5.) Detailed bathymetry of the area (Fig. 5) shows the 

 position, orientation and depth of the isolated shoals with respect to the cape shoals and 

 shoreline. Shallow basins (—60 feet MLW) separate the isolated shoals from the 

 shore-connected shoals. 



The BuU lies 6.5 miles east of the shoreline and 2.8 miles southeast of the tip of Chester 

 Shoal. Oriented in a northeast direction, like the tip of Chester and Southeast Shoals 

 (Shoals D and E, Fig. 5), the BuU is about 5.1 miles long and slightly over 2 miles wide. 

 Rising to within 15 feet of the surface, the shoal is visible in aerial photos, including Hetzel 

 and Ohio Shoals which rise to 20 feet MLW. 



Ohio Shoal and Hetzel Shoal, separated by a shallow, narrow slough lies 4 miles north of 

 The Bull and 9 miles east of False Cape. (See Figures 4 and 5.) Both shoals are more 

 irregular in shape than The BuU. Ohio Shoal has a northeast orientation, while Hetzel Shoal, 

 and the combined form of both shoals is oriented northwest. Survey data shows the 

 Hetzel-Ohio Shoal complex is sUghtly asymmetrical in cross section— the landward flank is 

 steeper and more even than the seaward slope. 



Several mUes north of Chester Shoal Ues a larger north-trending shoal (Shoal A, Fig. 5) 

 which rises to 15 feet MLW. Shoal A is about 2.7 miles long and 1,100 yards wide. Between 

 Shoal A and Chester Shoal the bottom is shghtly deeper than 30 feet MLW, but near the
