Anthropogenic sound and marine mammal health: measures of the nervous and immune systems before and after intense sound exposure
Anthropogenic sound is a potential stressor for marine mammals that may affect health, as has been demonstrated in other mammals. Therefore, we have initiated investigations on the effects of intense underwater sounds on nervous system activation and immune function in marine mammals. Blood samples...

Anthropogenic sound is a potential stressor for marine mammals that may affect health, as has been demonstrated in other mammals.
