Miller Ian immiller@uw.edu 0000-0002-3289-6337 2019 Shoreline survey data collected at Rialto Beache, Washington State, 2018-03-20 dataset https://doi.org/10.1594/PANGAEA.902562 2019-06-12T07:47:38 https://doi.org/10.1594/PANGAEA.902570 Data were collected using GNSS survey methods, with a differential GPS operating in Real Time Kinematic (RTK) mode. All data were collected with an AshTech ProMark 200 RTK-DGPS system connected to the Washington State Reference Network. Horizontal positions are referenced to NAD83(2011) and the vertical data are referenced to NAVD88(Geoid09). All survey data were collected with the GNSS system mounted on a 2.05 m rover pole, held level as a transect line was traced in a cross-shore orientation on the beach. The associated text files include the horizontal (HRMS) and vertical (VRMS) root-mean-square errors estimated by the GNSS system, as well as the RTK-DGPS status reported by the GNSS system at the time each point was collected. Times are referenced to local Pacific time (either PST or PDT). Most data in these files are intended to be used to calculate beach profiles, but two other data types were collected during each survey: 1) Grain size photos, the locations of which were surveyed in the field and denoted in the "Description" field. The photos are currently available by request. 2) The location of the most seaward presence of large wood on the profile. These data were collected as part of a one year project intended to characterize seasonal shoreline position variability on the complex shoreline of Washington's Olympic coast. The project was jointly supported by the North Pacific Coast Marine Resources Committee, Washington Sea Grant, and Peninsula College. -126.1564407 -126.1529457 48.8181928 48.8192265 -126.15460144132838 48.81850208763841 2018-03-20T11:07:37 2018-03-20T11:52:07 0.27 7.35 not specified Rialto_Beach 48.818252 -126.154357 GNSS Receiver GNSS 2168 CC-BY-4.0 Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/ LATITUDE Latitude http://en.wikipedia.org/wiki/ISO_6709 Miller Ian immiller@uw.edu 0000-0002-3289-6337 Latitude LONGITUDE Longitude http://en.wikipedia.org/wiki/ISO_6709 Miller Ian immiller@uw.edu 0000-0002-3289-6337 Longitude ELEVATION Elevation m a.s.l. http://en.wikipedia.org/wiki/Elevation elevation http://purl.obolibrary.org/obo/PATO_0001687 Length L http://dbpedia.org/resource/Length Miller Ian immiller@uw.edu 0000-0002-3289-6337 Elevation [m a.s.l.] DATE/TIME Date/Time http://en.wikipedia.org/wiki/ISO_8601 Time T http://dbpedia.org/resource/Time Miller Ian immiller@uw.edu 0000-0002-3289-6337 Date/Time Horizontal root mean square error HRMS m mean Length L http://dbpedia.org/resource/Length Miller Ian immiller@uw.edu 0000-0002-3289-6337 HRMS [m] Vertical root mean square error VRMS m mean Length L http://dbpedia.org/resource/Length Miller Ian immiller@uw.edu 0000-0002-3289-6337 VRMS [m] Status Status Miller Ian immiller@uw.edu 0000-0002-3289-6337 GPS Status Description Description description Miller Ian immiller@uw.edu 0000-0002-3289-6337 Description citable Beach profiles Olympic National Park Washington Coast author69395 event2907064 geocode1599 geocode1600 geocode1601 geocode8128 license21 method11851 param170569 param170570 param7055 param79845 pi69395 term1073934 term40710 term40958 term43863 term43975 term49412 term49413 term49414 topotype1
