Outline conclusions1. Akrotiri was probably not a gateway to the Cyclades for Minoans, but more

likely a central point of return from the wider Aegean2. The natural route for Minoan trading ships was to the East via Rhodes3. The destruction of Santorini might not have had a material effect on the

stability of maritime networks in the Southern Aegean

Next steps4. Complete the data and analysis for this select data set5. Complete the maritime risk mapping for the select data set

Future possibilities6. Apply the model to the entire Aegean data set7. Compare the outcomes and models with archaeological data8. Test the model over different and wider area e.g. the Indian Ocean
