Marine Mammal Observers mitigate the potential impact of sound exposure on marine fauna during geophysical surveys, naval active-sonar exercises, UXO clearance or, civil engineering projects.

This app will assist the MMO in making mitigation decisions by calculating the distance from the animal to the source of acoustic interference using a trigonometric cosine function. The MMO enters the distance and bearing to the TARGET and SOURCE from their observation position and the app calculates the rest.
