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.

ORWA26PTS_UTM is a point coverage containing digital hydrographic datacollected off the coast of Washington and Oregon, USA. The horizontaldatum is Universal Transverse Mercator, Zone 10 meters. The data setincludes National Ocean Service (NOS) hydrographic surveys collectedbetween 1926 and 1974 (primarily 1926 to 1930). It includes the mostrecent bathymetric data available on a regional scale over the inner toouter continental shelf off the coast of Washington and Oregon.

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.

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...
