Figure F21. Close-up of time-migrated seismic reflection section of Study of Continental Rifting and Extension on the Eastern Canadian Shelf (SCREECH) line 2MCS at Site 1277. Positive reflection amplitudes are red to yellow, and negative amplitudes are gray to black. The black line approximates the depth of basement penetration. Note the irregularly "layered" character of the uppermost basement. CMP = common midpoint.
