Description: This layer is a composite of several years of aerial kelp surveys off Oregon. A coastwide survey was conducted in 1990, reef-specific surveys at 5 south coast reefs (Blanco, Orford, Redfish, Humbug and Rogue reefs) were conducted for 4 years from 1996 – 1999, and a regional survey was conducted from Cape Arago south to the California border in 2010. Three distinct survey designs were implemented for acquiring kelp bed imagery over two decades of kelp surveys. The target species was bull kelp, Nereocystis luetkeana. In 1990, the kelp survey was contracted to Ecoscan Resources Data. Kelp beds were photographed with black and white near infrared slide film. Interpretation methods included the application of a 50 meter radius to account for plant growth, and plants within 100 meters of each other (within 100 meters of the 50 meter radius) were included in a kelp polygon. ODFW designed the kelp surveys for 5 south coast reefs from 1996-1999. Specifications were established that ensured continuity between years. Bergman Photographic, Inc was contracted to acquire the imagery. Kelp beds were photographed using infrared photographic print film. Kelp beds were delineated without the addition of a 50 meter radius around kelp beds as was done with the 1990 data. In Oregon, the giant kelp, Macrocystis sp. is found only at Cape Arago. Both the 1990 and 2010 surveys covered Cape Arago, however only the 1990 survey delineation canopy for the giant kelp. In 2010, digital multispectral imagery of kelp canopy in southern Oregon was acquired and gridded at 1m resolution. The geographic coverage of the aerial survey is from Cape Arago (located near Coos Bay) to the Oregon-California border.

Description: This data set delineates geological seafloor characteristics of the continental margin of the United States West Coast adjacent to Washington, Oregon, and Northern California. The data set depicts seafloor substrate types as interpreted from a multitude of seafloor mapping surveys, including multibeam sonar, sidescan sonar, sediment grab samples, cores samples, seismic reflection profiles, and still or video images. Seafloor types are classified according to three unique classification schemes: (1) The Active Tectonics and Seafloor Mapping Lab's SGH codes, (2) Greene et. al. (1999) deep-water marine benthic habitat scheme, and (3) the Coastal and Marine Ecological Classification Standard's Substrate Component. This dataset has been developed since 2002 and is now at version 4.0. Version 4.0 SGH Map provides significant changes and modifications from previous versions. The major modifications from previous versions are as follows: 1. Merged in new local-scale habitat maps from detailed mapping at 13 sites over Washington, Oregon, and Northern California. 2. Implemented numerous attribute table clarifications and modifications including a clarification of the use of primary, secondary lithologic type. 3. CMECS Substrate Component codes added by crosswalking SGH codes to CMECS SC codes. 4. Appended habitat polygons for Northern California from the 2005 EFH Consolidated GIS Volume 1 (2004) data set geohab_woc.shp developed by Gary Greene and the Center For Habitat Studies at Moss landing Marine Labs. Significant modifications or updates to continental shelf and slope habitat types of Northern California were made to the Greene et al. map based upon newly available bathymetry in the region. 5. Appended California State Waters mapping Program Tier II map products for northern California. The Tier II habitat maps used in this regional habitat map were acquired, processed, archived, and distributed by the Seafloor Mapping Lab of California State University Monterey Bay and are available in their origianal form at: http://seafloor.otterlabs.org/SFMLwebDATA.htm

Description: The CMECS polygons for Olympia oysters (Ostrea lurida) represent intertidal regions at or near observed oyster beds. Shore lines were selected from the Oregon Shorezone ‘Unit_line’ layer, which breaks the shore line into segments, based similar physical characteristics. Each ‘Unit_line’ segment from Oregon Shorezone, selected by its proximity to an Olympia oyster bed observation, was buffered by the corresponding intertidal width described in the ‘Xshr’ table of Oregon Shorezone.
