Figure 117. Generalized bathymetric map of Marquesas Keys and reef tract area west of Key West, Florida, shows locations of shallow (water depth 5-23 m) wells drilled between 1959 and 1962 (Table 9, after Dustan et al., 1991). Site D/E-1 represents two adjacent wells on a seagrass/gorgonian hardbottom 2 km southeast of the Marquesas (Table 10, after Dustan et al., 1991). Well 826Y was drilled on limestone bedrock 7 km northeast of the Marquesas. Well A was drilled from a jackup rig on coral bottom. Well C was drilled on sandy bottom, and well B, a few kilometers west of C, was drilled on a coral knoll. Well symbols are standard industry symbols for dry wells but are colored red for easy detection in this figure. Stippled pattern represents shallow submerged shelf.
