- 255100: EAARL-B Coastal Topography—Fire Island, New York, pre-Hurricane Sandy, 2012: Seamless (Bare Earth and Submerged)
This shapefile was produced from 53 2-kilometer by 2-kilometer tile extents of remotely sensed, geographically referenced elevation measurements by the U.S. Geological Survey. Elevation measurements w... - 255101: Bathymetry data for the post-construction survey of the Emergent Sandbar Habitat project at river mile 761.4 downstream from Gavins Point dam on the Missouri River.
This geospatial data set contains the points collected by the echosounder on transects in the downstream project reach surrounding the construction area at River Mile 761.4 below Gavins Point Dam on t... - 255102: DS926 Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system in Florida and parts of Georgia, Alabama, and South Carolina -- Streams represented in study area
Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system were developed to define an updated hydrogeologic framework as part of the U.S. Geological Survey Ground... - 255103: ArcInfo Grid of the 30 meter pixel Composite Bathymetry of Boston Harbor and Approaches (BH_30MBATH, UTM 19, WGS84)
These data are high-resolution bathymetric measurements of the seafloor from Boston Harbor and the harbor approaches, Massachusetts. Approximately 170 km square of sidescan sonar and bathymetric data... - 255104: LANDFIRE Remap Forest Canopy Base Height (CBH) Micronesia
LANDFIRE’s (LF) Remap Canopy Base Height (CBH) supplies information used in fire behavior models to determine the critical point at which a surface fire will transition to a crown fire. CBH data are... - 255105: Conductivity, temperature and salinity time-series data collected in 2009 in the vicinity of Wainwright, Alaska
Measurements of conductivity and temperature were collected with a high-accuracy conductivity and temperature recorder (Seabird SBE37 microcat) in approximately 10 m water depth at a single location f... - 255106: Airborne geophysical survey: Dillon (Pioneer-Beaverhead), Montana Survey Part 1 of 2
Aeromagnetic data were collected along flight lines by instruments in anaircraft that recorded magnetic-field values and locations. This datasetpresents latitude, longitude, altitude, and magnetic-fi... - 255107: PNG format images of EdgeTech SB-512i chirp seismic-reflection data collected in May 2012 by the U.S. Geological Survey within the Baltimore Canyon, mid-Atlantic margin
A large number of high-resolution geophysical surveys between Cape Hatteras and Georges Bank have been conducted by federal, state, and academic institutions since the turn of the century. A major goa... - 255108: DS926 Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system in Florida and parts of Georgia, Alabama, and South Carolina -- Major groundwater divides of the Floridan aquifer system
Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system were developed to define an updated hydrogeologic framework as part of the U.S. Geological Survey Ground... - 255109: DS926 Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system in Florida and parts of Georgia, Alabama, and South Carolina -- Contours for thickness of the Floridan aquifer system
Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system were developed to define an updated hydrogeologic framework as part of the U.S. Geological Survey Ground...
