Bottom Reflection Loss in an Area in the Hatteras Abyssal Plain
Bottom reflection loss measurements were made along three tracks in a 1 degree quadrangle, designated Area C, extending from 33 deg 00' to 34 deg 00'N and 71 deg 00' to 72 deg 00'W. The area lies along the northwestern edge of the Hatteras Abyssal Plain. Explosive sound sources w...
