Single-channel seismic-reflection profiles and sidescan-sonar records collected on Georges Bank
David C. Twichell
1981, Open-File Report 81-438
Subbottom seismic-reflection, echo-sounding, and sidescan-sonar records were collected by the U.S. Geological Survey during two cruises over Georges Bank aboard the R/V OCEANUS (cruise 056, March 6-15, 1979 and cruise 067, August 6-13, 1979) (fig. 1). The data collected during these two cruises contributed to a study of bed-form types...
