Saginaw Bay Restoration Assessment Dikes

This dataset is the output of a python script/ArcGIS model that identifies dikes as having a difference in elevation above a certain threshold. If the elevation difference was below a certain threshold the area was not considered a dike; however, if the difference in elevation between two points was significantly high then the area was marked as a dike. Areas continuous with eachother were conside

Western Lake Erie Restoration Assessment Dikes

This dataset is the output of a python script/ArcGIS model that identifies dikes as having a difference in elevation above a certain threshold. If the elevation difference was below a certain threshold the area was not considered a dike; however, if the difference in elevation between two points was significantly high then the area was marked as a dike.

Connecting River Systems Restoration Assessment Degree Flowlines

This represents the flowline network in Connecting River Systems Restoration Assessment (CRSRA). It is attributed with the number of disconnections between the reach and the connecting river system. These data will help identify the condition of hydrologic separation between potential restoration areas and the connecting river system. Low numbers represent fewer disconnections such as culverts bet

Connecting River Systems Restoration Assessment Composite Model

Well-established conservation planning principles and techniques framed by geodesign were used to assess the restorability of areas that historically supported coastal wetlands along the U.S. shore of the connecting rivers (Detroit River and St. Clair River). The resulting analysis supported planning efforts to identify, prioritize, and track wetland restoration opportunity and investment in the r

Western Lake Erie Restoration Assessment Composite Model

Well-established conservation planning principles and techniques framed by geodesign were used to assess the restorability of areas that historically supported coastal wetlands along the U.S. shore of western Lake Erie. The resulting analysis supported planning efforts to identify, prioritize, and track wetland restoration opportunity and investment in the region. To accomplish this, publicly avai

Three GIS datasets defining areas permissive for the occurrence of uranium-bearing, solution-collapse breccia pipes in northern Arizona and southeast Utah

Some of the highest grade uranium (U) deposits in the United States are hosted by solution-collapse breccia pipes in the Grand Canyon region of northern Arizona. These structures are named for their vertical, pipe-like shape and the broken rock (breccia) that fills them. Hundreds, perhaps thousands, of these structures exist. Not all of the breccia pipes are mineralized; only a small percentage o

EAARL-B Submerged Topography-Crocker Reef, Florida, 2014

These datasets provide lidar-derived topography for a portion of the submerged environs of Crocker Reef, Florida. Elevation measurements were acquired on April 13 and 22, 2014 by the second-generation Experimental Advanced Airborne Research Lidar (EAARL-B). The authors acknowledge Emily Klipp, Richard Mitchell, Karen Morgan, Chris Pali, Virgil Rabine, Rudy Troche, and Wayne Wright for planning ef

Multi-species Coral Sr/Ca Based Sea-Surface Temperature Reconstruction Data Using Orbicella faveolata and Siderastrea siderea from Dry Tortugas National Park, Florida

New sub annual and mean annual Sr/Ca records from two species of massive coral, Orbicella faveolata (coral B3) and Siderastrea siderea (coral CG2), from the Dry Tortugas National Park, FL (DRTO). Both corals have well-constrained chronologies, with coral B3 ranging from 1893-2008 and coral CG2 ranging from 1837-2012. We combine these new records with published Sr/Ca data from three additional S. s
