Long Term Contamination of the Marine Environment
  - Estimating contaminant exposure with otolith cross-sections from southern bluefin tuna using 'time of flight' secondary ion mass spectrometry

CIs: Kirstin Ross

This study proposes to use the very sensitive technique offered by Time of Flight Secondary Ion Mass Spectrometry to determine mercury concentrations, and their form, in wild caught SBT otoliths. The data collected will give an indication of the mercury deposition over time in the otoliths, which has been shown with other metals to be related to environmental concentrations. Research to date has been to assess the potential of the ToF-SIMS technique using snapper otoliths.
