description The use of multibeam sonar mapping techniques to refine population estimates of the endangered white abalone is discussed. The amount of suitable habitat available for the endangered white abalone is quantified to aid in obtaining accurate estimates of the number of remaining individuals at two offshore banks and one island site off the coast of southern California. Habitat is mapped by using multibeam sonar survey techniques and categorized using rugosity and topographic position analysis. Abalone densities are evaluated using a remotely operated vehicle and video transects methods. The total amount of suitable habitat at these three suites is far greater than that previously estimated.
