The supporting objectives are to: • Determine if previous geophysical surveys have identified the wrecks; • Establish positional accuracy of the wrecks; • Evaluate the wreck history, specifically for UXO; • Undertake a qualitative risk assessment for each wreck based on the aforementioned factors; • Produce criteria to determine a reasonable avoidance buffer.

If so, confirm the type and quantity of munitions carried; • Determine the positional accuracy according to the historical data. For the purposes of this report 6 Alpha have graded the positional accuracy of the wrecks using the following three categories: o Good – Wreck that has been identified and corroborated during previous geophysical surveys; o Moderate – Discrepancy between positional data sources; o Poor – No evidence of positional accuracy found. • Determine whether the wreck is intact or if it has broken up. And in the latter case whether there is related debris; • Review the geophysical data captured during the early stages of the project to see if this survey had covered the wreck location and if so, whether it had identified the shipwreck; • For the shipwrecks that were identified from the geophysical survey, there was the option to refine the positional accuracy. However both the original and new coordinates have been presented within this report for completeness; • Conduct a qualitative risk assessment based on the findings for the aforementioned stages and then set avoidance distance parameters.
