Human activities have a profound impact on marine ecology in Greenland. In this presentation, I will focus on a study of the impact of these activities on narwhals. I will present different stochastic models to analyze the data from this study: point process with memory, stochastic Langevin diffusions. These diffusion processes can be multidimensional, hypoelliptic (with a degenerate noise) and partially observed. I will discuss the question of parameter estimation when only discrete observations are available.
