To provide biological noise predictions for passive and active performance predictions, one would ideally need to know where the marine mammals are and then predict where they are going to be. The inputs to the marine mammal behaviors are the future environment, especially where the food and ideal living conditions are going to be in the future, the state of the mammal (in a group, alone, healthy, sick, gestation, etc.) and a probabilistic model of the mammal intelligence to forecast what the mammal(s) may do including their vocalization. In this first phase, we will focus on predicting the future environment, especially the biogeochemical conditions using our MIT Multidisciplinary Simulation, Estimation, and Assimilation Systems (MSEAS).
