Online_Linkage: http://pubs.usgs.gov/sir/2012/5290/ Description: Abstract: The U.S. Geological Survey (USGS) Saltmarsh project at Acadia National Park(ANP)involved surveying elevation reference marks (ERMs) and points on the marsh surface for 20 marshes in the study area. Vertical control was established using previously-published benchmarks and one base station that was not previously published. This feature class contains location, elevation, and names for the ERMs used to establish vertical control for the marsh points. Purpose: ERM points were used as datum to survey elevations of marsh points. Supplemental_Information: Geodatabase product of a USGS study funded by National Park Service Climate Change Response funding, NPS PMIS # 161531, "Inventory and Protection of Salt Marshes from Risks of Sea Level Rise at Acadia National Park, Maine", 2012. The database layers are collectively termed "appendix 1" of the USGS SIR report. Database layers included in appendix 1 include: Surveyed benchmarks used in surveying exercise (SIR2012_5290_ACAD_SurveyedBMs); Surveyed marsh points used for quality control for LiDAR data (SIR2012_5290_ACAD_Surveyedmarshpoints); Surveyed elevation reference marks for each surveyed marsh (SIR2012_5290_ACAD_SurveyedERMs); Salt marshes inventoried for this study (SIR2012_5290_ACAD_Saltmarshpolys); Inundation lines for each marsh under 60 cm of sea level rise (SIR2012_5290_ACAD_Inundationlines); Potential barriers to migration of salt marshes (SIR2012_5290_ACAD_Potentialbarriers). The inundation lines presented are in no way a prediction of whether marsh migration will actually occur, only indications of where land will be inundated and would therefore be available for migration under 60 cm. of sea level rise.

Process_Step: Process_Description: Technique used a Global Positioning System (GPS) receiver (base) on a survey monument having a known elevation. The base units received GPS signals from U.S. GPS satellites, computed a positional error, and broadcast the error to a second GPS receiver (rover) that occupied an ERM. Rover-unit occupation times ranged from 15 to 48 minutes with an average occupation time of 30 minutes. Rover receiver data were used in conjunction with base point elevation solutions to compute ERM elevations. ERM elevations were solved using the LGO 2.0 software. GEOID09 was the geoid model used to convert ellipsoid heights to orthometric heights above the North American Vertical Datum of 1988 (NAVD88). Process_Date: 2010 Process_Step: Process_Description: X, Y, and Z coordinates from the survey data were put in a text file and imported into ArcGIS and saved as a shapefile. Process_Date: 2010 Process_Step: Process_Description: Converted LGO elevation data in feet to meters (feet x .3048 = meters).
