Summary

This study precisely located two World War II shipwrecks, the German Kormoran and HMAS Sydney, using cognitive analysis of survivor reports. This method refined predictions, overcoming earlier inefficient and ambiguous historical methods.

Area of Science:

Maritime Archaeology
Naval History
Cognitive Science

Background:

Locating historical shipwrecks presents significant challenges due to imprecise historical data and environmental factors.
Previous searches for the German raider Kormoran and Australian cruiser HMAS Sydney were hampered by inefficient prediction methods.
The rich database of survivor accounts offers potential for advanced cognitive analysis.

Purpose of the Study:

To precisely define the locations of the World War II shipwrecks Kormoran and HMAS Sydney.
To evaluate the effectiveness of cognitive prediction methods compared to traditional approaches in shipwreck hunting.
To explore the role of trans-disciplinary and cognitive analysis in complex research projects.

Main Methods:

Utilized cognitive prediction based on nine reports from over 70 survivors of the HMAS Sydney sinking.

Keywords:

cognition decision making error memory mental models shipwreck hunting trading zones

Applied historical and oceanographic prediction models, noting their inefficiencies.

Analyzed survivor testimonies to establish a precise target position for the wrecks.

Main Results:

Achieved a precise "mean" target position 2.7 nautical miles from the Kormoran wreck.
Demonstrated that cognitive analysis of survivor reports provided accurate prediction for both wrecks.
Identified initial assumptions about HMAS Sydney's location as inaccurate, with cognitive analysis placing it near Kormoran.

Conclusions:

Cognitive prediction, leveraging detailed survivor accounts, is a highly effective method for locating shipwrecks.
The study highlights the limitations of traditional historical and oceanographic prediction in complex maritime searches.
The research underscores the importance of cognitive analysis and questions the decomposability of expertise in trans-disciplinary research.
