Abstract:

The methods of estimating the density and distribution of giant kelp, Macrocystic pyrifera, and substrate type, using side-scanning and down-looking sonar are described. These techniques provide quantitative assessments of changes in kelp population density, distribution, and substrate exposure. This paper presents the results of these developments and includes a description of the sonar methodology and a summary of the data gathered to evaluate the sonar technique and its effectiveness.
