Remote Sensing Oyster Reef Project

Oyster Reef Mapping

Traditional methods for monitoring subtidal oyster reefs rely upon extractive sampling techniques such as dredges, tongs, or quadrat sampling by divers. Remote sensing methods such as acoustic sounders and underwater video have the potential to greatly enhance the amount of detailed spatial information that can be obtained compared to traditional approaches. This project will compare acoustics (single beam, multibeam, and sidescan sonar), video, and quadrat sampling for characterizing the size and structure of three reefs, with the long-term aim being development of a general monitoring protocol. A report (see Grizzle et al. 2005 in RECENT PUBLICATIONS) will be available describing preliminary studies that led to this project. Ray Grizzle, Semme Dijkstra, and Brian Smith are the principal investigators. (Funded by NH Sea Grant; 2004-2006.)
