Interacting effects of vessel noise and shallow river depth elevate metabolic stress in Ganges river dolphins

2019

Scientific Reports

Dey, Mayukh, Krishnaswamy Jagdish, Morisaka Tadamichi, and Kelkar Nachiket

In riverine ‘soundscapes’, complex interactions between sound, substrate type, and depth create difficulties in assessing impacts of anthropogenic noise pollution on freshwater fauna. Underwater noise from...
