Abstract

Eelgrass Density in the SF Bay Using Side-Scan Sonar and Bathymetric Imagery
Track: Education
Authors: Chris Zumwalt

Eelgrass beds in the San Francisco Bay are both ecologically valued and protected. Mapping the bed’s extent and plant density with field surveys alone, can be difficult and very costly. We developed an efficient and accurate model using ArcGIS and remote sensing software using underwater side-scan sonar imagery and bathymetric data. Sharing our success and difficulties with the ESRI UC community will be rewarding for both presenter and audience.
