Description

Abstract: In 2006, the Marine Habitat Project conducted a pilot ROV survey on Orford Reef. This reef lies to the southwest of Cape Blanco, and is the principal fishing location for commercial fishing vessels from Port Orford harvesting nearshore species. The reef was surveyed with sidescan sonar in 1995 by the Geologic Survey of Canada covering 24 km2. A multibeam sonar survey yielding detailed bathymetric information, at a resolution of one meter, was performed under ODFW contract by SeaVisual Consulting that covered 42 km2 (Fox et al. 1999). Previously, fishes in shallow waters of Orford Reef had been surveyed using SCUBA gear (Fox et al. 1996, Miller et al. 1997). These surveys were components of studies of the kelp resource of Orford and neighboring reefs conducted from 1996 through 1999 (Fox et al. 1999). The 2006 pilot ROV survey had three principal objectives. First, could the ROV, along with its ancillary equipment, be successfully and safely operated using a small commercial fishing vessel as an operational platform. Second, to determine how much survey coverage could be made per day over several days of sea-time. Third, to collect preliminary information on densities of Orford Reef fishes, and if possible, to compare these results to previous SCUBA survey results. In additional to the principle objectives, we took this opportunity to examine and discuss differences between fine scale and coarse scale methods for interpreting habitat types on a rocky reef.

Lineage-Source: Final Report for 2005-06 Grant Cooperative Agreement No. PS06005 This work was funded by the Oregon Department of Land Conservation and Development Coastal Management Program through a Section 309 Program Enhancement Grant from the Office of Ocean and Coastal Resource Management of the National Oceanic and Atmospheric Administration, and by the State Wildlife Grant (USFWS) for implementation of the ODFW Nearshore Strategy. The Port Liaison Project provided funding for fishermen involvement in planning and vessel modifications that were otherwise not covered through our contract.
