Have you measured the acoustic characteristics of the Aframax class oil tankers that Kinder Morgan would use in its proposal to quadruple the monthly number of these vessels in the Salish Sea? You state that container vessels are loudest but the max. size of those vessels seems to be well below that of the Aframax tankers. I have studied Pacific herring responses to vessel noise, not responses by marine mammals. Pacific herring is a key species in the coastal marine food web of the Pacific NW (Canada's SW).
