Dear Marman Readers Greetings from Mozambique. We are looking for any papers that will assist us in our work to limit jetki's (small power craft) in Mozambiquan waters where marine mammals are resident. I have in the past read that the frequency of theses craft interfere with marine mammals echo frequency causing disorientation and stress. Any assistance in this regard would be appreciated.
