I sent this email earlier, but that attachment exceeded the attachment
limit so I am linking the attachment.

Attached is a figure showing a collection of velocity profiles across
a region.  The goal would be to group each of theses curves into
groups with similar characteristics

My idea is to group the entire profile for two reasons:
  1) The goal is to randomly generate similar profiles.
  2) The layering sequence within a profile is dependent on the
geologic conditions. So the relationship between adjacent layers would
be different for different groups, and would require more variables to
describe.
If you clustered using thickness and velocity, then you would
also have to consider depth as well.
