Description:
Abstract:
The U.S. Geological Survey (USGS) Salt marsh 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 vertical control points (published benchmarks and project benchmarks) used to establish vertical control for the ERMs and marsh points. In some cases, the project benchmarks are the same point as a published benchmark, and in some cases the project benchmark (BMs) were established close to the published benchmark, usually because the published benchmark was in a location that was not conducive to the placement of a base-receiver (usually because of tree cover).
Purpose:
Published benchmarks and other base stations used for differential Global Positioning System (GPS) surveying of ERMs and 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:
The elevations of the BMs were determined using Leica high-precision (millimeter accuracy) dual-frequency GPS receivers. This technique used a GPS receiver (base) a survey monument having a known elevation; base-unit occupation times ranged from 5 hr to 10 hr 53 min, with an average occupation time of 7 hr 33 min. Base-receiver data were submitted to the NGS using OPUS (<http://www.ngs.noaa.gov/OPUS/about.jsp>). Base point elevations were solved by OPUS using the CORS network (<http://www.ngs.noaa.gov/CORS/>).
Process_Date: 2010

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.
