As an augmentation of LITHOPROBE's southern Alberta transects (SALT) in general, and the Vibroseis augmented listen time (VAuLT) experiment in particular, a pair of 3- C spreads were shot with extended listen times (55 s) in mid-October 1995 near Claresholm, Alberta. Our objectives in proposing this survey were: (1) determination of crustal Poisson's ratio; (2) regional P-SV analysis of the sedimentary basin; (3) study of crustal and upper mantle anisotropy; (4) determination of crustal attenuation properties for both P and S waves. At present, only a few sample shot records have been correlated, of which two are here illustrated.
