of paper presented at the Joint Statistical Meetings, Dallas, August 9-13,1998. Naomi S. Altman, Chair, Dept. of Biometrics, 434 Warren Hall, Cornell University, Ithaca, NY 4853-7801 ([email protected]); C. Clark, Director, ([email protected]); K. Fristrup, Asst. Director ([email protected]), and K. Dunsmore, Research Asst. Bioacoustics Research Program, Cornell University, Ithaca, NY Hydroacoustics have become increasingly important to supplement or replace visual observation of whales and other marine mammals. In this poster session I summarize approaches to a number of studies including: use of dual mode (acoustic and visual) surveys of whales to determine population size, tracking individual animals from acoustic detections, and determining the response of marine mammals to noisy human activities. Statistical methods employed include distance sampling, penalized nonlinear models and graphical methods based on nonparametric smoothing.
