Fundamental Science Practices
USGS provides unbiased, objective, and impartial scientific information upon which our audiences, including resource managers, planners, and other entities, rely.
USGS provides unbiased, objective, and impartial scientific information upon which our audiences, including resource managers, planners, and other entities, rely.
Our programs produce accurate geologic maps and 3-D geologic frameworks that provide critical data for sustaining and improving the quality of life and economic vitality of the Nation. They also organize, maintain, and publish the geospatial baseline of the Nation's topography, natural landscape, built environment and more.

Aeromagnetic map of the El Malpais Instant Study Area and adjacent areas, Valencia County, New Mexico Aeromagnetic map of the El Malpais Instant Study Area and adjacent areas, Valencia County, New Mexico
The Federal Land Policy and Management Act (Public Law 94-579, October 21, 1976), requires the U.S. Geological Survey and the U.S. Bureau of Mines to conduct mineral surveys on certain areas to determine their mineral resource potential. Results must be made available to the public and be submitted to the President and the Congress. This report presents the results of a mineral survey of...

Aeromagnetic map of the Mokelumne Wilderness and contiguous Rare II further planning areas, central Sierra Nevada, California Aeromagnetic map of the Mokelumne Wilderness and contiguous Rare II further planning areas, central Sierra Nevada, California
The aeromagnetic map consists of parts of two surveys flown at an altitude of 300 m above the average ground surface. One survey (west park of the map_ centered over the Mokelumne Wilderness was flowing in a northeast-southwest direction along slight lines spaced at a horizontal interval of about 800 m (U>S> Geological Survey, 1979b). The survey to the east is part of a regional survey...

Appearance and distribution of the gas hydrate reflection in the Blake Ridge region, offshore southeastern United States Appearance and distribution of the gas hydrate reflection in the Blake Ridge region, offshore southeastern United States
A strong reflection parallel to the sea floor has been observed in seismic-reflection profiles in the Blake Ridge area off the southeastern United States. This reflection occurs at a subbottom depth of 400 to 700 m, in water depths of 750 to 3750 m. Because the reflection parallels the sea floor, it is known as a bottom-simulating reflection (BSR). It is independent of reflections that...
Bathymetric map of the Blake Escarpment Bathymetric map of the Blake Escarpment
The Blake Escarpment is a steep cliff tlmt trends north-south approximately 400 km east of Florida. Across the escarpment, which marks the eastern edge of the Blake Plateau, water depths increase from about 1,500 m to 5,000 m. In the past few years the area has been surveyed by the following U.S. Geological Survey cruises: 1. R/V Eastward (cruise 80-8); 2. R/V Starel!a; 3. R/V Gittiss...
Bathymetric map of the continental slope and uppermost continental rise between Lindenkohl Canyon and South Toms Canyon, offshore Eastern United States Bathymetric map of the continental slope and uppermost continental rise between Lindenkohl Canyon and South Toms Canyon, offshore Eastern United States
This map was prepared as part of a study of geologic hazards to resource exploration and development on the Continental Slope in the Baltimore Canyon Trough area, off southern New Jersey. Detailed bathymetric maps are required for enfineering studies of bottom stability and for geologic interpretation of the nature of the submarine topography. This map presents the morphology of the...
