Photo of Dredge Site Location

View of city of Honolulu from offshore dredge disposal area in Mamala Bay. The seafloor bathymetry off Honolulu is quite steep, and water depth drops off fairly quickly. Although the disposal site is in deep water (~ 450 m), it is within 5 km of the shoreline. (Photograph by M.E. Field, USGS)
