Mapping and Classification

Before risks from underwater munitions can be managed, they must first be located, identified, and understood. The processes of mapping, classification, and identification form the foundation for all further action, whether it involves risk assessment, remediation, or long-term monitoring. Without reliable data on where munitions are and what condition they are in, no effective strategy can be developed.

These activities involve detecting, documenting, and analysing munitions present on or beneath the seafloor. The aim is to determine their type, quantity, distribution, and level of degradation, as well as the potential risks they pose. The results directly inform decisions across environmental protection, offshore development, and maritime safety.

Since munitions degrade over time and marine conditions constantly change, these processes must be regularly updated and refined to reflect the best available information, technological capabilities, and strategic priorities.

A Combined Effort: Archival, Field and Data-Based Work

Effective mapping, classification, and identification rely on a combination of historical research, in-situ investigation, and advanced data analysis:

Archival Research provides insight into where munitions may have been dumped or lost, drawing on military records, naval logs, shipping data, and other historical sources.

 

Field Study uses modern tools such as sonar, magnetometers, and remotely operated vehicles (ROVs) to detect and verify the presence of munitions on the seafloor and assess their condition.

 

Data Analytics integrates information from historical and field sources, helping to classify findings, identify patterns, and support large-scale risk assessments. It also enhances detection accuracy and enables long-term planning.

 

Together, these processes provide a comprehensive understanding of underwater munitions and help prioritise areas for further investigation or action. They are essential for ensuring that decisions are based on solid, up-to-date evidence and that risks are managed effectively.
