Physical significance of the TAR parameter alpha
Luyendyk, Bruce P.
A preliminary study of the properties of the TAR parameter alpha was done to attempt to determine the dependence of alpha on physical properties of the marine section it operates on. A certain correlation was found between alpha and water depth. Correlations were also found between alpha and the depth of basement. Thus it was found that alpha varies inversely with water depth because of the increase in sedimentary section, or depth of basement, seaward. An inverse relationship holds down the continental slope since the section is thinning here. On offshore cross-sections studied, alpha also varied inversely as to the two way time to the depth of basement. This variance of alpha with the length of sedimentary data on records was attributed to properties of the GAGC system. Shorter sections cause the GAGC to level off earlier and thus vary the time at which T2 occurs. With T2 occurring at earlier times on shorter sections, the interval T2-T1 decreases, thereby increasing the value of alpha.
