Abstract : The Population Consequences of Acoustic Disturbance (PCAD) model (NRC 2005) provided a framework to trace the effects of acoustic disturbance through the life history of a marine mammal to its population status. Developments in the model have been designed to determine if the effects of any disturbance can be traced from individuals to the population by way of changes in either behavior or physiology, and the revised approach is called PCOD (Population Consequences Of Disturbance). In North Atlantic right whales (Eubalaena glacialis), extensive data on health and body condition, anthropogenic impacts, and individual life history exists. The primary goal of this study is to model visual observations of health, human impacts (including entanglements and ship strikes), and whale locations to provide estimates of true underlying condition and individual level survival for right whales. Secondary goals include modeling fecundity, and exploring the feasibility of incorporating acoustic disturbance and prey variability into the PCOD model.
