Computer-implemented methodology for being visually informative as to risks associated with sea mines which may be present in geographical regions of interest. A region is selected, topographical data pertaining to such region is acquired, a "safe-depth" (water depth demarcation between significant risk thereabove and insignificant risk therebelow) is designated, and a map of such region is displayed. In a visibly differentiable manner, the map depicts existing water areas in which sea mine risk is significant, existing water areas in which sea mine risk is insignificant, and existing land areas. In relation to a particular region, the nature and bounds of sea mine risk and/or lack thereof can be readily, completely and detailedly ascertained by viewing a computer display and effectuating appropriate computer operations. On individual ships, alarms can be installed which suitably actuate responsively to sea mine risks.
