    Abstract

    Forensic investigations involving the recovery of firearms from water bodies are limited by the current lack of an accepted method of estimating time since deposition. This study explored the potential to model corrosion rates of submerged firearms over time to estimate time since deposition for forensic applications.

    Twelve rifles and 24 barrel pieces were submerged at two marine locations in Perth, Western Australia. Samples were recovered every four months over a two year period. The level of depletion caused by corrosion was measured using SEM and SEM/EDX and modelled against various water properties and submergence time.
