ORWA26_500UTM: Oregon/Washington 500 meter, 1926 Bathymetry Grid;UTM Projection

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.

An update of Quaternary faults of central and eastern Oregon

This publication updates previous fault maps of Oregon as a contribution to the larger U.S. Geological Survey effort to produce digital maps of active faults in the Pacific Northwest region. The new map is derived from the 1992 fault map of Pezzopane, Nakata, and Weldon that has seen wide distribution and has been reproduced in essentially all subsequent compilations of active faults of Oregon. This publication provides a substantial update of known active or suspected active faults east of the Cascades. Improvements in the new map include (1) many newly recognized active faults, (2) a linked ArcInfo map and reference database, (3) more precise locations for previously recognized faults on shaded relief quadrangles...

Shaded-relief and Color Shaded-relief maps of the Willamette Valley, Oregon

This digital dataset was compiled from newly released U.S.Geological Survey 10-meter digital elevation model (DEM) data,along with stream and transportation coverages previouslypublished on the internet. This report consists of a digitalrepresentation of the physiography of the Willamette Valley.Contained in this dataset is: 1) 10-meter DEM data for the entireWillamette Valley; 2) the ARC/INFO grids used to create the colorshaded-relief and gray scale shaded-relief images; 3) thenecessary data ARC/INFO data to used to plot these data; and 4)several reports detailing the data formats (this docuement) andproducers used to create these datasets. The scale of theoriginal 10-meter DEM data should not be violated. Any...

Cascadia tsunami deposit database

The Cascadia Tsunami Deposit Database contains data on thelocation and sedimentological properties of tsunami depositsfound along the Cascadia margin. Data have been compiled from52 studies, documenting 59 sites from northern California toVancouver Island, British Columbia that contain known orpotential tsunami deposits. Bibliographical references areprovided for all sites included in the database. Cascadiatsunami deposits are usually seen as anomalous sand layers incoastal marsh or lake sediments. The studies cited in thedatabase use numerous criteria based on sedimentarycharacteristics to distinguish tsunami deposits from sandlayers deposited by other processes, such as river floodingand storm surges. Several...

ORWA98_750UTM: Oregon/Washington 750 meter, 1926/1998 BathymetryGrid; UTM Projection

ORWA98_750UTM is a digital bathymetric surface grid of the seafloor offthe coast of Washington and Oregon. Grid cell spacing is 750m and theprojection is UTM Zone 10.The surface grid was produced by merging National Ocean Service (NOS)Hydrographic Surveys conducted between 1926 and 1974 (primarily 1926to 1930) with recent surveys conducted by the U.S. Army Corps of Engineers(USACE) in 1998 around the entrances to Grays Harbor, Willapa Bay, and theColumbia River. The results of this work represent the best availableestimate of the seafloor morphology for the time period circa 1998. Theuser is cautioned, however, to use this data set with full knowledge ofthe original intent, the limitations, and assumptions used...
