Enhanced Terrain Imagery of the Reading 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution

This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Reading 30 x 60 minute quadrangle in Pennsylvania and parts New Jersey. It also covers part of the Delaware River Basin. The source data used to construct this imagery consists of 1-meter and 3-meter resolution Lidar-derived digital elevation models (DEMs). The lidar source data were compiled from different acquisiti

Enhanced Terrain Imagery of the Wilmington 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution

This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Wilmington 30 x 60 minute quadrangle in parts of Pennsylvania, Maryland, Delaware, and New Jersey. It also covers part of the Delaware River Basin. The source data used to construct this imagery consists of 1-meter and 3-meter resolution Lidar-derived digital elevation models (DEMs). The lidar source data were compil

Database for the Geologic Map of the South Boston 30' x 60' Quadrangle, Virginia and North Carolina

The 1:100,000-scale geologic map database of the South Boston 30' x 60' quadrangle, Virginia and North Carolina, provides geologic information for the Piedmont along the I-85 and U.S. Route 58 corridors and in the Roanoke River watershed, which includes the John H. Kerr Reservoir and Lake Gaston. The Raleigh terrane (located on the eastern side of the map) contains Neoproterozoic to early Paleozoi

PRISM3 Pliocene Global Sea Surface Temperature Reconstruction

PRISM3D uses multiple proxies to develop February and August synoptic reconstructions of the surface ocean. Planktonic foraminiferal assemblages were translated to February and August surface temperatures via factor analytic transfer function and the modern analog technique. Mg/Ca and alkenone paleothermometry were incorporated as supplementary data for the first time in a PRISM reconstruction. In

Alkenone and foraminifer abundance data from Miocene and Pliocene Atlantic Coastal Plain sediments

Alkenone data were extracted from core and outcrop samples from the Miocene and Pliocene of the mid Atlantic Coastal Plain. The Uk'37 index is used to estimate temperature and total C37 is used to estimate productivity. Planktonic foraminifer abundance's are provided for two cores.

2015-2017 lidar-derived imagery of karst areas in Puerto Rico at 1-meter resolution

This raster dataset contains 1-meter lidar-derived imagery of 7.5 minute quadrangles in karst areas of Puerto Rico and was created using geographic information systems (GIS) software. Lidar-derived elevation data, acquired between 2015 and 2017, were used to create a 1-meter resolution working digital elevation model (DEM). To create this imagery, a hillshade was applied and a topographic position

2018 lidar-derived imagery of karst areas in Puerto Rico at 1-meter resolution

This raster dataset contains 1-meter lidar-derived imagery of 7.5 minute quadrangles in karst areas of Puerto Rico and was created using geographic information systems (GIS) software. Lidar-derived elevation data, acquired in 2018, were used to create a 1-meter resolution working digital elevation model (DEM). To create this imagery, a hillshade was applied and a topographic position index (TPI) r

Enhanced Terrain Imagery of the Newark 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution

This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Newark 30 x 60 minute quadrangle. It covers portions of New Jersey and New York, including parts of the Delaware River Basin. The source data used to construct this imagery consist of 1-meter, 2-meter, and 3-meter resolution lidar-derived digital elevation models (DEM). The lidar source data were compiled from differ

Lidar-derived closed depression vector and density raster in karst areas of the Winchester 30 x 60-minute quadrangle

The Winchester 30 x 60 minute quadrangle, covering northern Virginia, West Virginia, and Maryland, hosts karsts within carbonate units of Devonian to Cambrian age. Lidar-derived elevation data, acquired between 2011 and 2019, were used to create a mosaic of 1-meter resolution working digital elevation models (DEMs), from which surface depressions were identified using a semi-automated workflow in

Enhanced Terrain Imagery of the Middletown 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution

This imagery dataset consists of 3-meter resolution, Lidar-derived imagery of the Middletown 30 x 60 minute quadrangle. It covers part of New York, New Jersey, Pennsylvania, and part of the Delaware River Basin. The source data used to construct this imagery consists of 1-meter, 2-meter, and 3-meter resolution lidar-derived digital elevation models (DEM). The lidar source data were compiled from d

Density raster of caves in Monroe County, West Virginia

Monroe County, in southeastern West Virginia, hosts world-class karst within carbonate units of Mississippian and Ordovician age. There are at least 412 known caves in the county. Location data for these caves were collected from the West Virginia Speleological Survey (WVASS) Bulletin 22 (Dasher, 2019). Point features were created in ArcGIS Pro for each cave location and were used to make a point
