In order to deduce the age-depth relationship in an ice or sediment core,
geoscientists face a challenging forensic reasoning problem. The data are
heterogeneous, noisy, and often voluminous; worse yet, the geological
processes that produced those data, and that affected them between creation
and sampling, are unknown.  Working backwards through all possible
scenarios about the core's history involves navigating a combinatorial
explosion of possibilities.  Even experts---who can quickly prune out less
likely scenarios---can get overwhelmed in this situation, as can the
computers that sling the data and run the equations that operationalize the
hypotheses. Software support for this task is extremely limited, so very
few papers in the current literature explore the space of possibilities
very broadly.  I will talk about two automated reasoning tools---one
complete and one under development---that use artificial intelligence
techniques and modern cyberinfrastructure technology to effectively aid
experts in this challenging task.
