Figure F20. Time-migrated seismic reflection sections showing Study of Continental Rifting and Extension on the Eastern Canadian Shelf (SCREECH) lines 2MCS and 206 where they cross 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. For line locations, see Figure F6 in the "Leg 210 Summary" chapter. CMP = common midpoint.
