(a) (upper) Single-fold CDP section showing far offset shots for SP 1, SP 2, and SP 6 of the SEAL-2000 profile. The Moho reflections are indicated by black solid arrow. (lower) CDP stack section offset linked to near traces for the SEAL-2000 profile. Several reflections in the crust and the Moho are identified by red broken lines and black solid arrows, respectively. In addition, reflections from the bottom of the ice sheet are traced by the light-blue broken line. All the figures are after Kanao et al. [17]. (b) (upper) Single-fold CDP section showing far offset shots for SP 1 and SP 7 of the SEAL-2002 profile. The Moho reflections are indicated by black solid arrows. (lower) CDP stack section with offset limited to traces within 120 km for the SEAL-2002 profile. Several reflections in the crust and the Moho are identified by red- and black-colored broken lines. In addition, reflections from the bottom of the ice sheet are traced by the light-blue broken line. All the figures are after Kanao et al. [17].
