Description:
Abstract:
In 2010-2012, The USGS investigated salt marshes in and around Acadia National Park (ANP) from Penobscot Bay to the Schoodic Peninsula to map the potential for landward migration of marshes using a static inundation model of a sea-level rise (SLR) scenario of 60 cm (2 ft). These inundation maps will enable resource managers to proactively adapt to sea level rise by identifying and targeting for conservation or further investigation low lying coastal areas adjacent to salt marshes that are not now protected, and to identify risks to infrastructure in the coastal zone. This study mapped static inundation based on digital elevation models derived from light detection and ranging (LiDAR) topographic data collected in October 2010. Land-surveyed control points were used to evaluate the accuracy of the LiDAR data in the study area and yielded a root mean square error (RMSE) of 11.3 cm. An independent accuracy assessment of the LiDAR data specific to salt-marsh land surfaces indicated a RMSE of 13.3 cm and 95-percent confidence bound of +/- 26.0 cm. LiDAR-derived digital elevation models and digital color aerial photography, collected during low tide conditions in 2008 with a pixel resolution of 0.5 meters, were used to identify the highest elevations of each salt marsh surface in the study area. The highest elevation of each marsh was determined, and the 60-cm of sea level rise was applied to that elevation. Inundation contours for +60-cm SLR were produced for 114 salt marshes in the study area. Confidence bounds (95-percent, +/- 26.0 cm) were delineated above and below the +60 cm inundation lines, and artificial structures such as roads and bridges, which may present barriers to salt-marsh migration, were mapped. All inundation lines are stored in a geodatabase for use in a Geographic Information System (GIS).
Purpose:
These GIS layers were developed along with the final report (USGS SIR 2012-5290, Estimates of future inundation of salt marshes in response to sea level rise in and around Acadia National Park, Maine, by Martha Nielsen and Robert Dudley) for the identification of areas adjacent to salt marshes that are expected to be inundated after 60 cm of sea level rise occurs. The layers document the location and extent of the salt marshes, the extent of inundation expected around each marsh (with 95-percent confidence interval lines), potential manmade barriers to marsh migration, and all the surveying data collected as part of the project.
Supplemental_Information:
Geodatabase product of a U.S. Geological Survey 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.

Other_Citation_Details:
The LiDAR data were the primary outside source information for the study. The LiDAR data have a grid cell size of 2 m. Individual data tiles are 751x751 grid cells (1.5 km x 1.5 km) in size. As of October 2012, the LiDAR data are still availably only from state GIS offices. Final publication for public download has not been announced.
The project area required LiDAR to be collected on 2.0 meter GSD or better and processed to meet a bare earth vertical accuracy of 15.0 centimeters RMSEz or better. Raster DEMs were tested by Photo Science for both vertical and horizontal accuracy. All data is seamless from one tile to the next, no gaps or no data areas. The vertical unit of the data file is in decimal meters with 2-decimal point precision. The reported RMSEz was 0.113 m. USGS independently developed a RMSEz for saltmarsh landcover types to be 0.133 m.

Source_Contribution:
The LiDAR data were the primary outside data used in the study. The main use was to create accurate contours showing areas of upland that would be inundated with 60 cm of sea level rise (SLR) adjacent to saltmarshes in and around Acadia National Park. The USGS conducted an independent accuracy assessment of the elevation data to create 95-percent confidence interval contours on the SLR inundation contours. The data tiles were joined together into larger mosaics, and shaded relief images were created to for visualization of the land surface and to identify location/shape of potential barriers to migration of salt marshes.

Low-tide orthophotos from 2008 were used to delineate the polygon boundaries of most of the saltmarsh polygons used in the study, by looking at the visible changes in vegetation. They also were used to help identify the potential barriers to migration and to identify the type of barrier (road or railroad grade).

Acadia NP vegetation mapping database was used as the first cut for the location of ACAD salt marshes for inclusion in this project. All the salt marshes identified in the Acad Veg shapefile were checked on higher-resolution aerial photos, and a few were not used because they looked unlikely to be actual salt marshes or were mis-coded on the original source.
