Description

Abstract: We initiated a nearshore rocky reef research project in 1995 to begin gathering information necessary for managing nearshore reefs. This report summarizes work completed during 1999. One major work area during the last four years has been to examine methods to characterize reef bottom habitat. We successfully used side-scan sonar in 1995 and an acoustic ground discrimination system in 1998 to map seafloor habitat, but found the methods to be either too subjective or inconsistent. In 1999, we completed a high-resolution multibeam bathymetry survey of Orford Reef and developed methods to quantitatively classify reef bottom habitat. Section 2, below, presents the results of this work. In 1999, we also continued our kelp biomass study on the southern Oregon coast. Section 3 of this report includes the 1999 estimates of bull kelp (Nereocystis luetkeana) biomass at Orford, Blanco, Redfish, Humbug, and Rogue Reefs, and compares the results to previous years. Section 4 of the report discusses how the results of the 1999 work might affect nearshore reef management.
