Shadow Zone Explained
Hey, all.
A while back, I made a video called "Dangerous Waters Concepts: Sound Speed Profile," explaining the three different sound speed profiles in Dangerous Waters: bottom limited, surface duct, and convergence zone. I mentioned the "Shadow Zone" in passing, but felt it needed further discussion. The "Shadow Zone" is the area beneath the layer where you cannot hear / be heard by things on the other side of the layer. However, it's actually not as simple as saying, "below the layer means you're in the shadow zone." I also found experimentally the distance where the shadow zone starts based on layer depth and what that means for you tactically. Check out the video here:
