traveltime
(s)
Unit 1/2 864.8 6.982
Unit 2/3 929.2 7.03
Unit 3/4 1029.5 7.108
Unit 4/Subunit 5A 1069.4 7.147
Subunit 5A/5B 1129.8 7.201
Subunit 5B/5C 1502.1 7.516
Top of first sill 1612.8 7.598
Top of second sill 1719.4 7.681

Note: Based on laboratory measurements of sediment velocities below the lithologic Unit 1/2 contact. The Unit 1/2 contact is interpreted to correlate with the strong reflection in SCREECH line 2MCS data at 6.98 s.
