Abstract: With a background in geophysics in the form of near surface investigations, in recent years Dr Armour has been looking at various impact structures in Ontario, both known and suspected. 

Here, she will talk about known structures such as Brent and Holleford, as well as some suspected structures.

She will detail how she has been using gravity, seismology, and magnetics to be able to better model the subsurface structure of these objects.
