1986 Map of West of Franktown

About this map

Chesapeake Bay bathymetry dominates this 1980s nautical study, detailing the underwater contours and marine topography off the Virginia coast. The map illustrates a complex network of submerged channels and shoals, providing a technical look at the seafloor character in an area essential for regional maritime navigation. A specific Disposal Area is demarcated in the southwestern portion of the sheet, reflecting mid-century maritime management and sediment deposition practices. Compiled from National Ocean Service hydrographic surveys, the data captures the precise depths and varying gradients of the coastal shelf at a time when precision mapping was becoming increasingly sophisticated through tide-coordinated data collection.
