Notes on the CREWES Interface Parameter Converter
The Interface Parameter Converter is designed to be a convenient
tool for converting data on interfaces between earth layers
into various useful formats. For instance, given the
compressional velocity (a), and
shear velocity (b),
for each side of the interface,
one can calculate ratios (e.g. b1/a1),
or conrasts (e.g. Dr/r)that are commonly used in AVO applications.
Some other symbols employed in this applet are s (the Poisson ratio) and
b/a = (b1+b2)/(a1+a2). The
subscript "1" indicates the upper layer and "2" the lower layer.
