SET-MH were read repeatedly at regular, at least annual intervals. Reading SETs consisted of measurements for nine pins facing the four cardinal directions for a total of 36 measurements per SET, per sampling event.  Marker Horizons consisted of a marker, usually white feldspar clay, so that the sediment that accumulated on top of the marker would be visible and measurable to the nearest millimeter.  Together, SET-MH provide information on surface elevation changes due to surface accretion (MH) compared to changes that may be due to subsurface processes (such as root growth or groundwater swelling).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9R0HL3R", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.671acd98d34efed5620fd160.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_671acd98d34efed5620fd160", "keyword": ["Emergent Tidal Marsh", "Puget Sound", "Salt Marsh", "USGS:671acd98d34efed5620fd160", "ecology", "elevation", "environment", "land surveying", "wetland ecosystems"], "modified": "2024-11-12T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-122.74544, 47.06825, -122.68639, 47.10799", "theme": ["geospatial"], "title": "Marker Horizon Data at the Nisqually River Delta, Washington"}
