<p>The response variables (fish sound production) are labeled in green. The predictor variables (oceanographic data) are labeled in red next to their corresponding vector that indicates the direction and strength of their correlation to the response variables. Vector length is proportional to importance in explaining variation in response variables. Grey circles are each response variable displayed in RDA space. The proximity between the predictor vectors and the response variables reflect their correlation (closer proximity indicates stronger correlation). Due to close proximity and overlap with other vectors, some vectors may be difficult to discern. Bb represents the backscatter (β<sub>(650 nm, 117°)</sub>) variable.</p
