Identifier 1994-031-FA
Alternate names 94-12
Purpose Sidescan survey LEO-15 area surveyed June 1991 to document storm changes to inner shelf setting.
Location Little Egg Inlet, New Jersey, United States, North America, North Atlantic;
Summary This was a 2-ship multidisciplinary acoustical survey: CTDs during daylight, sidescan sonar at night. Early sidescan problems were solved with second QMIPS trigger box. Entire area was successfully surveyed at 150-m spacing.
