Understanding Underwater Acoustic Activity
Life underwater is driven and determined by sensory cues. Light, temperature, salinity, and sound all play pivotal roles in guiding marine organisms through their life stages and determining what behaviours are most appropriate given their environmental surroundings. The perception and creation of sound is arguably the most important natural process controlling the dynamics of the undersea world.
Sound, unlike light, can travel to and from the deepest reaches of the oceans and accomplish this at speeds far greater than on land. Indeed, sound is by and large the best and most efficient way to sense and map underwater landscapes and study many of the organisms found in each oceanic region. Not surprisingly, sound detection has evolved as the primary sense for countless species of marine fauna and is often more advanced than other sensory adaptations like vision.
