West Coast Exclusive Economic Zone
The purpose of this data layer is to provides a general basemap showing the extent of the U.S. Exclusive Economic Zone. The EEZ consists of those areas adjoining the territorial sea of the U.S., the Commonwealth of Puerto Rico, the commonwealth of the Northern Mariana Islands, and U.S. overseas territories and pssessions. The EEZ extends up to 200 nautical miles (370 km) from the U.S. coastline.
Exclusive Economic Zone (EEZ) and Maritime Boundaries; Notice of Limits By Presidential Proclamation No. 5030 made on March 10, 1983, the United States established an exclusive economic zone, the outer limit of which is a line drawn in such a manner that each point on it is 200 nautical miles from the baseline from which the breadth of the territorial sea is measured. The U.S. EEZ is the largest in the world, containing 3.4 million square miles of ocean and 90,000 miles of coastline. The Government of the United States of America has been, is, and will be, engaged in consultations and negotiations with governments of neighboring countries concerning the delimitation of areas subject to the respective jurisdiction of the United States and of these countries. The limits of the exclusive economic zone of the United States as set forth below are intended to be without prejudice to any negotiations with these countries or to any positions which may have been or may be adopted respecting the limits of maritime jurisdiction in such areas. Further, the limits of the exclusive economic zone set forth below are without prejudice to the outer limit of the continental shelf of the United States where that shelf extends beyond 200 nautical miles from the baseline in accordance with international law.
Heads of Tide
This dataset was originally created by Randall Sounhein (2000) from the "Heads of Tide for Coastal Streams in Oregon " study conducted by the Department of State Lands in March 1989. All digitization was conducted against 1:24,000 USGS Quads and 1:24,000 Digitial Ortho Quads of 1996 vintage.
Oregon Continually Updated Shoreline Product OCMP - 2015
Oregon’s continually updated shoreline was compiled to create a comprehensive shoreline of Oregon’s ocean and estuary shore at Mean High Water. This data set was created to deliver continuous shoreline to support various GIS applications including coastal and marine spatial planning, environmental studies, and cartography.
This data layer is an element of the Oregon GIS Framework. The Oregon CUSP shoreline represents a "best of" attempt to create a continuous Mean High Water Shoreline for use in GIS analysis and inventory work. Whenever possible the Oregon CUSP shoreline references a mean-high water shoreline based upon vertical modelling or image interpretation, using both water level stations and/or shoreline indicators. CUSP is primarily built from LiDAR NGS National Shoreline data for the outer Pacific ocean coast and Oregon Lidar Consortium data for the inner estuarine coast.
Oregon ShoreZone - 2014
The ShoreZone program is a partnership of scientists, GIS specialists, web specialists, nonprofit organizations, and government agencies. Please see ShoreZone.org or CoastalAndOceans.com for a list of partner agencies and related web sites. The ShoreZone mapping system provides a spatial framework for coastal habitat assessment on local and regional scales. Research and practical applications of ShoreZone coastal mapping data and imagery include: linking habitat use and life-history strategy of nearshore fish and other intertidal organisms; habitat capability modeling (for example, to predict the spread of invasive species or the distribution of beaches appropriate for fish spawning); ground-truthing of aerial data on smaller spatial scales; natural resource planning and environmental hazard mitigation; and public use for recreation, education, outreach, and conservation.
Pacific Northwest Marine Shoreline
This is a compilation of shoreline data as sourced from the Ministry of Sustainable Resource Management (MSRM), the Washington ShoreZone data set assembled by the Department of Natural Resources, and NOAA's environmental sensitivity index (ESI) shoreline for Oregon. Both British Columbia and Washington adopted the ShoreZone mapping system and protocol for their shoreline inventory, which provided some measure of consistency across the international border. This data set was compiled by The Nature Conservancy for the Pacific Northwest Coast Marine ecoregional assessment. Its inclusion in ODFW’s Nearshore Ecological Data Atlas (NEDA) is intended strictly as a reference cartographic layer.
An estuary, as defined here by Oregon Fish and Wildlife, is a semi-enclosed body of water, connected to the ocean, where salt water is measurably diluted with fresh water from the land.
This dataset depicts Oregon's rocky shoreline. The rocky shoreline includes beaches or the base of cliffs that have rocky substrate, including cobble, gravel, boulder and bedrock. Rocky shoreline was delineated from color-infrared aerial photographs of the entire Oregon coast shot at minus tides in 1994. This feature class was revised on 6/15/2012. This reversion corrects for the omission of rock island features. The purpose of this dataset was to delineate shoreline features for resource management and spatial planning purposes.
This dataset depicts Oregon's sandy shoreline. The sandy shoreline includes beaches or the base of cliffs that have only sand substrate. The sandy shoreline was delineated in 2005 from color-infrared aerial photographs of the entire Oregon coast shot at minus tides in 1994. The purpose of this dataset was to delineate shoreline features for resource management and spatial planning purposes.
Oregon Rocks and Islands
This dataset was prepared by The Nature Conservancy for inclusion as a reference layer in ODFW’s Nearshore Ecological Data Atlas (NEDA). In addition to rocks added in estuaries, the layer consists primarily of features describing offshore islands and rocks as selected from the 'source dataset' described by the rest of these metadata.The source dataset depicts tracts of land (parcels) administered by the U.S. Fish and Wildlife Service (FWS) in Oregon, Washington, Idaho, Hawaii, a portion of Nevada, and the U.S. Trust Territories in the Pacific Ocean. The tracts of land included in this inventory compose National Wildlife Refuges, National Fish Hatcheries, FWS administrative offices and other conservation areas.
Boundary of the Pacific Northwest Marine Ecoregion
This polygon represents The Nature Conservancy's Pacific Northwest Marine Ecoregion. It includes all the estuaries along the coast and extends westward out to the toe of the continental slope. It does not include Puget Sound.The area located within Canadian waters, from the international boundary to the tip of the Brooks Peninsula, is being analyzed by the British Columbia Marine Conservation Analysis (BCMCA) http://www.bcmca.ca/.
Essential Fish Habitat Conservation Areas
These data depict Essential Fish Habitat (EFH) conservation areas off Washington, Oregon, and California. The coordinate locations are from NMFS' Final Rule to implement Amendment 19 to the Pacific Coast Groundfish Fishery Management Plan (71 FR 27408; May 11, 2006). In order to minimize to the extent practicable adverse effects from fishing, the final rule prohibits fishing with various gear types within these areas. Consult the text of the final rule for specific details about each area and the management measures. The prohibitions are listed in Section 660.306 and the official coordinates are listed in Sections 660.397, 660.398, and 660.399 of the final rule. These data were developed to support implementation of NMFS' Final Rule implementing amendment 19 to the Pacific Coast Groundfish Fishery Management Plan (FMP).
Nearshore Ecological Data Atlas (NEDA)
This dataset was developed by NOAA's Biogeography Branch and The Nature Conservancy in Oregon as a common index for modeling efforts in development of the Oregon Dept. of Fish and Wildlife's (ODFW) Nearshore Ecological Data Atlas.
The purpose of developing estuary metrics in the Territorial Sea planning effort was to map the influence of the estuary on the nearshore ocean.
This dataset contains three metrics - Salmon Ranking, Nursery Area Proxy, and a Non-salmonid fish ESA (Endangered Species Act) critical habitat score – which collectively serve as a proxy for estuary influence on nearshore marine habitats. Each metric was used as a separate conservation target in the NEDA (Nearshore Ecological Data Atlas) Marxan analysis performed by TNC (The Nature Conservance) for ODFW (Oregon Department of Fish and Wildlife) in December 2011 and each is represented across those NEDA planning grid cells constituting the rank-based “attribution areas” associated with different estuaries (see below). Data Layers:I. Salmon Ranking:All freshwater outlets to the ocean (i.e., streams, rivers, estuaries) that harbor significant runs of salmonid species were ranked according to their perceived importance relative to both species diversity and abundance (species-specific or cumulative).
The purpose of this survey was to update ODFW's kelp biomass surveys of the mid 1990's.This layer shows the spatial extent of kelp canopy in Oregon based on 5 years of kelp surveys. Bull kelp grows in nearshore waters on rocky substrate, but does not occur on all rocky substrate.Therefore, these data cannot be used to indicate location and extent of all rocky substrate. Bull kelp is limited to depths of less than 60 ft. Annual variations occur in the distibution and density of kelp.
Gray Whale Migration Corridor - Oregon Coast
This dataset was developed for inclusion in ODFW's (Oregon Department of Fish and Wildlife) Nearshore Ecological Data Atlas to inform general marine spatial planning and Oregon's Territorial Sea Planning process in the context of the mitigation and siting of wave energy development.
This layer shows the primary pathway used by migrating gray whales off the Oregon coast. This dataset was produced using specific depth contour values based on a gray whale migration study summarized in Ortega-Ortiz and Mate (2008). The results from this study were extrapolated to the entire Oregon coast based on their consistency with similar studies conducted elsewhere on the West Coast of North America. The 10th and 90th percentiles of depth values for each phase of the gray whale migration were used to demarcate the inshore and offshore boundaries of the migratory pathway. Phases of gray whale migration and 10th-90th percentile depth ranges are classified as: "Southbound" (34 - 65 m), "Northbound phase A" (31 - 62 m), and "Northbound phase B" (mothers and calves, 15 - 59 m). As a composite of these three phases, the migratory pathway in this dataset extends over the depth range 15-65 m including the Westermost depth contour, the shallowest Easternmost contour for migration without calves, and the shallowest Easternmost contour of migration of mothers with calves. While this layer shows the primary migratory pathway, gray whales often occur both in shallower and deeper waters.
Green Sturgeon Critical Habitat (Estuaries)
This data set depicts the West Coast estuarine waters designated as Critical Habitat for the Southern Distinct Population Segment (DPS) of Green Sturgeon. These Estuary Polygons were derived from NOAA's Medium resolution digital Vector Pacific Coast Shoreline.
The purpose of this data set is to provide a general basemap for the location of estuarine areas designated as Endangered Species Act (ESA) critical habitat for the threatened Southern DPS (Distinct Population Segment) of Green Sturgeon. The data DO NOT constitute a legal description of critical habitat (which can be found in the agency's Federal Register notice describing the designation - see 74 FR 52300, October 9, 2009).
Green Sturgeon Critical Habitat (Head of Tide)
The purpose of these data is to identify the upstream head-of-tide extent for selected estuaries identified in NMFS' 2009 final rule to designate critical habitat for the southern DPS (Distinct Population Segment) of Green Sturgeon. This GIS dataset contains points indicating the approximate head of tide locations in coastal estuaries designated as critical habitat for the Southern Distinct Population Segment (DPS) of green sturgeon. The critical habitat is defined in the National Marine Fisheries Service's 2009 final critical habitat rule for this DPS (see 74 FR 52300, October 9, 2009).
Additional information regarding the process for designating critical habitat for this species can be found at http://www.nwr.noaa.gov/Other-Marine-Species/Green-Sturgeon.cfm Additional information regarding the process for designating critical habitat for this species can be found at http://www.nwr.noaa.gov/Other-Marine-Species/Green-Sturgeon.cfm
Green Sturgeon Critical Habitat (Marine Coastal Zones)
The purpose of this data set is to provide a general basemap for the location of marine areas designated as Endangered Species Act (ESA) critical habitat for the threatened Southern Distinct Population Segment (DPS) of North American Green Sturgeon. The data DO NOT constitute a legal description of critical habitat (which can be found in the agency's Federal Register notice describing the final designation - (50 CFR Part 226 Page 52300, October 13, 2009). This layer represents the marine areas designated as Endangered Species Act (ESA) critical habitat for the threatened Southern Distinct Population Segment (Southern DPS) of North American Green Sturgeon. These areas include coastal U.S. marine waters within 60 fathoms depth (110 meters - see supplemental info) from Monterey Bay, California (including Monterey Bay), north to Cape Flattery, Washington, including the Strait of Juan de Fuca, Washington, to the U.S.-Canada boundary. Critical habitat is defined in the National Marine Fisheries Service's (NMFS) final rule for Southern DPS Green Sturgeon critical habitat (see 72 FR 52084, September 8, 2008).
Green Sturgeon Critical Habitat (Streams)
This data set depicts the Stream waters designated as Critical Habitat for the Southern Distinct Population Segment (DPS) of Green Sturgeon. The data was derrived from the National Hydrography Dataset (NHD). This data was developed to show what streams are designated as Green Sturgeon Critical Habitat. The data DO NOT constitute a legal description of critical habitat (which can be found in the agency's Federal Register notice describing the critical habitat designation - see 74 FR 52300, October 9, 2009).
Green Sturgeon Critical Habitat (Tribal Exclusions)
This data set depicts the approximate boundaries of Indian Lands excluded from designation as critical habitat under the Endangered Species Act (ESA) for Southern Distinct Population Segment (DPS) green sturgeon. This data was created by digitizing lines representing approximate tribal territory shorelines that overlap with areas designated as critical habitat for Green Sturgeon. The data DOES NOT constitute a legal description of critical habitat exclusions (which can be found in the agency's Federal Register notice describing the critical habitat designation - see 74 FR 52300, October 9, 2009).
Groundfish Habitat Areas of Particular Concern
These data were developed for National Marine Fisheries Service and Pacific Fishery Management Council to support implementation of Amendment 19 to the Pacific Coast Groundfish Fishery Management Plan (FMP).
These data depict areas designated as Habitat Areas of Particular Concern (HAPC) for Pacific Coast Groundfish. Groundfish HAPC's include seagrass, canopy kelp, rocky reefs, estuaries, and specified areas of interest. HAPCs based on habitat type may vary in location and extent over time, and are determined by the defining characteristics that are described in detail in Amendment 19. For these reasons, these GIS data are only an approximation of the location of these HAPCs. The areas of interest HAPC are defined by discrete boundaries.
Groundfish Habitat Areas of Particular Concern (HACP) - Areas of Interest
These data depict areas designated as Areas of Interest which are a subset of Habitat Areas of Particular Concern (HAPC) for Pacific Coast Groundfish. Groundfish HAPC's include seagrass, canopy kelp, rocky reefs, estuaries, and specified areas of interest. HAPCs based on habitat type may vary in location and extent over time, and are determined by the defining characteristics that are described in detail in Amendment 19. For these reasons, these GIS data are only an approximation of the location of these HAPCs. In contrast, the areas of interest HAPC are defined by discrete boundaries. These data were developed for National Marine Fisheries Service and Pacific Fishery Management Council to support implementation of Amendment 19 to the Pacific Coast Groundfish Fishery Management Plan (FMP).
Leatherback Sea Turtle Critical Habitat
This area represents the approximate location of Critical Habitat Area 2, in the Leatherback Sea Turtle critical habitat designation process. This data set was designed to approximate the critical habitat area within Oregon for use in the Territorial Sea Planning process. Description of Area 2: Nearshore area from Cape Flattery, Washington, to Umpqua River (Winchester Bay), Oregon and offshore to a line approximating the 2000 meter isobath.
Pinniped Haulout and Rookery Locations
This dataset was created to document haulout/rookery locations in Oregon and faciliate population status and trend monitoring by ODFW staff. Points may indicate a "specific" location of a haul-out or rookery (e.g., a single offshore rock) or a more "general" area in which animals will likely be found (e.g., a large stretch of rocky intertidal habitat). Attribute data includes species-specific site use and abundance for Pacific harbor seals (Phoca vitulina), northern elephant seals (Mirounga angustirostris), Steller sea lions (Eumetopias jubatus), and California sea lions (Zalophus californianus). Parturition sites (rookeries) for Steller sea lions are identified but not for harbor seals as they may give birth nearly everywhere that adults are found (California sea lions do not breed in Oregon and northern elephant seals only occassionaly give birth at Cape Arago). Data are based primarily on average counts from recent aerial surveys (last 5-10 years) which typically occur in May, June and July.
Stellar Sea Lion Critical Habitat
This data set depicts Designated Critical Habitat for Stellar Sea Lion in Oregon. It is meant as a general locational reference for these designated areas.
These data are intended to represent the areas designated as Critical Habitat for Stellar Sea Lions in Oregon by delineating a 3,000 foot buffer around the 3 islands or rocks where the specfied rookeries are located. The Federal Register Notice of August 27, 1993 gives the final rule for "Designated Critical Habitat; Steller Sea Lion". For Oregon it calls out 3 locations offshore in Curry County; 2 in the Orford Reef region and 1 in the Rogue Reef region. In Oregon, major Steller sea lion rookeries and associated air and aquatic zones are designated as critical habitat. Critical habitat includes an air zone extending 3,000 feet (0.9 km) above rookery areas historically occupied by sea lions. Critical habitat also includes an aquatic zone extending 3,000 feet (0.9 km) seaward from the baseline or basepoint of each major rookery indicated in Table 1 in Part 226 of the Federal Register Notice.
Western Snowy Plover Critical Habitat
These data depict critical habitat identified for the threatened Western Snowy Plover. Features for the species were extracted from the Oct 2010 update of the primary USFWS layer representing Critical Habitat designations.
Critical habitat are areas considered essential for the conservation of a listed species. These areas provide notice to the public and land managers the importance of these areas to the conservation of this species. Special protections and/or restrictions are possible in areas where federal funding, permits, licenses, authorizations, or actions occur or are required.
Human Use Datasets
Marine Gardens, Research Reserves, and Habitat Refuges, 2008
State Designated Marine Managed Areas for the State of Oregon. Summary layer consisting of the individual research reserves, marine gardens, and habitat refuge present in Oregon's Territorial Sea. This layer was developed for cartographic purposes only, in order to visually represent the aforementioned area.
Oregon Coastal Beach Access Sites
The beach access points theme was created to display the location of public beach access along the Oregon Coast. Boat ramp locations were added to the dataset to allow users to view the location of boat ramps along the Columbia River and the Willamete River north of the Oregon City Dam.
The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. The NHD is a national framework for assigning reach addresses to water-related entities, such as industrial discharges, drinking water supplies, fish habitat areas, wild and scenic rivers. Reach addresses establish the locations of these entities relative to one another within the NHD surface water drainage network, much like addresses on streets. Once linked to the NHD by their reach addresses, the upstream/downstream relationships of these water-related entities--and any associated information about them--can be analyzed using software tools ranging from spreadsheets to geographic information systems (GIS). GIS can also be used to combine NHD-based network analysis with other data layers, such as soils, land use and population, to help understand and display their respective effects upon one another. Furthermore, because the NHD provides a nationally consistent framework for addressing and analysis, water-related information linked to reach addresses by one organization (national, state, local) can be shared with other organizations and easily integrated into many different types of applications to the benefit of all.
Oregon Port Names
This dataset identifies port cities along the Oregon Coast. Its inclusion in ODFW’s Nearshore Ecological Data Atlas (NEDA) is intended strictly as a reference cartographic layer.The data was extracted from the OR GNIS layer http://www.oregon.gov/DAS/EISPD/GEO/sdlibrary.shtml (Oregon Geospatial Clearinghouse).
