Scientific Party (affiliate): Ralph Lewis-CT DEP, geologist, Chief Scientist
Scientific Equipment:
  • EG&G Uniboom seismic profiling system
  • EDO Western sidescan sonar system
  • Northstar LORAN-C navigation system
  • Texas Instrument Silent 700 system to record navigation
  • Analog tape recorder to record Uniboom seismics. 
Navigation techniques used: Loran-C
Cruise Funding Source:
Project Title: New England Coastal Geology
Remarks: Uniboom data were very good (excellent penetration and good resolution) except in areas where the acoustic signal was attenuated by gas in the sediments. Sidescan sonar records were satisfactory.
