There are three main components to the ESI: shoreline habitats, sensitive biological resources, and human-use resources. The shoreline and intertidal areas are ranked based on sensitivity determined by: (1) Shoreline type (substrate, grain size, tidal elevation, origin); (2) Exposure to wave and tidal energy; (3) Biological productivity and sensitivity; and (4) Ease of cleanup. The biology layers focus on threatened/endangered species, areas of high concentration and areas where sensitive life stages may occur. Supporting data tables provide species/location-specific abundance, seasonality, status, life history, and source information Human use resources mapped include managed areas (parks, refuges, critical habitats,...

Sandy ocean beaches are a popular recreational destination, often surrounded by communities containing valuable real estate. Development is on the rise despite the fact that coastal infrastructure is subjected to flooding and erosion. As a result, there is an increased demand for accurate information regarding past and present shoreline changes. To meet these national needs, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is compiling existing reliable historical shoreline data along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii under the National Assessment of Shoreline Change project.There is no widely accepted standard for analyzing shoreline...

ORWA26_500UTM is a digital bathymetric surface grid of the seafloor offthe coast of Washington and Oregon. Grid cell spacing is 500m and theprojection is UTM Zone 10.The surface was produced by gridding National Ocean Service (NOS)Hydrographic Surveys collected between 1926 and 1974 (primarily1926 to 1930). This work includes the most recent bathymetric dataavailable on a regional scale over the inner to outer continental shelfoff the coast of Washington and Oregon. The results represent thebest available estimate of the seafloor morphology for the time periodcirca 1926.

This portion of the USGS data release presents bathymetry data collected during surveys performed in the Columbia River littoral cell, Washington and Oregon in 2014 (USGS Field Activity Number 2014-631-FA). Bathymetry data were collected using four personal watercraft (PWCs) equipped with single-beam sonar systems and global navigation satellite system (GNSS) receivers. The sonar systems consisted of an Odom Echotrac CV-100 single-beam echosounder and 200 kHz transducer with a 9 degree beam angle. Raw acoustic backscatter returns were digitized by the echosounder with a vertical resolution of 1.25 cm. Depths from the echosounders were computed using sound velocity profiles measured using a YSI CastAway CTD during...

SWWA26_750UTM is a digital bathymetric surface grid of the seafloor off the coast of Southwest Washington and Northwest Oregon. Grid cell spacing is 750m and the projection is UTM Zone 10. The surface was produced by gridding National Ocean Service (NOS) Hydrographic Surveys collected between 1926 and 1928. This work includes the most recent bathymetric data available on a regional scale over the inner to middle continental shelf off the coast of Washington. The results represent the best available estimate of the seafloor morphology for the time period circa 1926.

Estuarine ecosystems are controlled by a variety of processes that operate at multiple spatial and temporal scales. Understanding the hierarchical nature of these processes will aid in prioritization of restoration efforts. This hierarchical Columbia River Estuary Ecosystem Classification (henceforth "Classification") of the Columbia River estuary is a spatial database of the tidally-influenced reaches of the lower Columbia River, the tidally affected parts of its tributaries, and the landforms that make up their floodplains for the 230 kilometers between the Pacific Ocean and Bonneville Dam. This work is a collaborative effort between University of Washington School of Aquatic and Fishery Sciences (henceforth "UW"),...

This digital dataset, compiled from previously published andunpublished data sources, contains a personal geodatabase andraster data of features related to the repeated inundation of theWillamette Valley and Portland basin by Missoula Flood waters inLate Pleistocene time. The feature classes contained within theWill_Valley geodatabase are called 'erratics', representing thelocations of ice-rafted erratics; 'contours', representinginundation levels associated with stratigraphic evidence ofrepeated floodings; and 'geology', representing the generaldistribution of Missoula Flood deposits. A stand-alone tablewithin the geodatabase contains geologic unit descriptions forthe geology polygons contained in the 'geology'...

Project Summary Climate change is projected to have substantial impacts on Pacific Northwest water resources and ecosystems. Recognizing this, resource managers have expressed growing interest in incorporating climate change information into long-range planning. The availability of hydrologic scenarios to support climate change adaptation and long-range planning, however, has been limited until very recently to a relatively small number of selected case studies. More comprehensive resources needed to support regional planning have been lacking. Furthermore, ecosystem studies at the landscape scale need consistent climate change information and databases over large geographic areas. Products using a common set of...

This portion of the USGS data release presents topography data collected during surveys performed in the Columbia River littoral cell, Washington and Oregon, in 2017 (USGS Field Activity Number 2017-666-FA). Topographic profiles were collected by walking along survey lines with global navigation satellite system (GNSS) receivers mounted on backpacks. Prior to data collection, vertical distances between the GNSS antennas and the ground were measured using a tape measure. Hand-held data collectors were used to log raw data and display navigational information allowing surveyors to navigate survey lines spaced at 100- to 1000-m intervals along the beach. Profiles were surveyed from the landward edge of the study area...

This portion of the data release provides the data used to develop the calibration equation for the images in Digital seafloor images and sediment grain size from the mouth of the Columbia River, Oregon and Washington, 2014 for the estimate of median grain size. This dataset includes 63 still images extracted from digital video imagery of sediment grab samples along with laboratory grain size analysis of the sediment grab samples taken from the mouth of the Columbia River, OR and WA, USA. Still images were extracted from video footage whenever the camera was resting on the sediment sample and individual sediment grains were visible and in focus. The images were used to calculate the calibration curve through auto-correlation...

This GIS dataset is the primary data product produced for the NW Climate Science Center-funded project, "Rangewide climate vulnerability assessment for threatened Bull Trout" (FRESC Study ID 851). We used predictions of temperatures in streams across approximately two-thirds of the species' range in the U.S. to map coldwater streams or “patches” suitable for spawning and early rearing of Bull Trout. Each patch consists of streams with contiguous reaches of cold water. Patches were delineated using medium resolution National Hydrography Dataset streams containing modeled temperatures available at 1 km intervals, as provided by the NorWeST project (http://www.fs.fed.us/rm/boise/AWAE/projects/NorWeST.html).Once the...

Two 21-day field operations were conducted in 1997 and 1998 in the estuaries and on the inner continental shelf off the northern Oregon and southern Washington coast. These cruises aboard the R/V Corliss were run in order to generate reconnaissance maps of the seafloor geology and the shallow subsurface stratigraphy using sidescan-sonar and seismic-reflection mapping techniques. The 1998 cruise also collected sediment grab samples, bottom photographs, and video images to verify the sidescan-sonar imagery and to document the seafloor geology. The combination of these data with previously collected sediment sample data (Roberts, 1974; Nittrouer, 1978; and Smith et. al., 1980) has been used to define the extent and...
