Presents proceedings of a February 1998 symposium, "Surveys, Status and Trends of Marine Mammal Populations," held in Seattle, Washington. Papers discuss state-of-the-art methods and theories for estimating marine mammal abundance for determining population status and trends, and present both survey design and analysis procedures for a variety of cetacean, pinniped, and carnivore species. Papers are organized in sections on survey design and application, visibility bias and missed observations, and modeling, and examine areas such as survey planning, combining line-transect and capture-recapture techniques, and Bayesian population dynamics modeling.

This volume comprises the proceedings of a symposium on marine mammal survey assessment methods, which took place in Seattle, Washington, USA.
