GIS and Information Management - GGGSC

We support the geospatial component of Mineral Resources Program research and provide public access to research results and geospatial information. We facilitate all aspects of the data life cycle, including the publication and archiving of geospatial information and products. We also develop and steward national-scale data layers considered foundational to the Mineral Resources Program as...

Remote Sensing and Dryland Management

Drylands (areas characterized by low precipitation, high evapotranspiration, and low soil moisture) occupy around 40-45% of the earth’s surface. Many drylands contain high biodiversity and provide essential ecosystem services (e.g., livestock forage, agricultural production, pollination) for nearly 1/3 of the world’s population who live in drylands.  Given limited precipitation and other...

usSEABED

usSEABED is the collaborative product of the U.S. Geological Survey, the University of Colorado, and other partners, and provides integrated data from small and large marine research efforts by many entities—federal and state agencies, local authorities, universities, as well as private and public consortiums.

Accessing usSEABED

Since the second half of the 20th century, there has been an increase in scientific interest, research effort, and information gathered on the geologic sedimentary character of the continental margins of the United States. Data and information from thousands of sources have increased our scientific understanding of the geologic origins of the margin surface, but rarely have those data been...

usSEABED data format and content

The USGS data release for the usSEABED database enables search and download of six interlinked files of output data and a seventh file that provides linked information about the original data sources. These files can be downloaded in their entirety and are also searchable through an online interface that allows for search and selection either through a GIS display or through a web form. Both...

dbSEABED: Data processing and mining

At the core of usSEABED is dbSEABED, a data-mining program based on the application of fuzzy set theory to marine geological and biological data. Fuzzy set theory allows expansion of coverage of the seafloor by the use of word-based data from core logs, sample descriptions, photos, and videos, as well as the more standard numeric data from a laboratory.

Parsing in dbSEABED

Numeric data mined from verbal logs, core or grab descriptions, shipboard notes, and photographic descriptions are classified as “parsed” data. Input data are maintained using the terms employed by the original researchers and are coded using phonetically sensible terms for easier processing by...

DETAILED AQUIFER MAPPING OF THE SPRINGVILLE, N.Y. AREA Erie, Cattaraugus, and Wyoming Counties, New York

Introduction Public-water systems at Springville and Yorkshire/Delavan, N.Y. along Cattaraugus Creek draw from local groundwater resources and serve about 5,500 people (U.S. EPA SDWIS database). The remainder of the population obtains water from domestic wells, many of them completed in glacial aquifers. A Cattaraugus Creek tributary valley (Buttermilk Creek) to the south is the site of the...

DETAILED AQUIFER MAPPING OF THE MALONE, N.Y. AREA (Adirondack foothills and St. Lawrence lowlands transect) Franklin County, New York

Introduction The Village of Malone, Franklin County, New York is located along the Salmon River where it exits the northern foothills of the Adirondack Mountains and flows northward across the St. Lawrence Lowlands until its confluence with the St. Lawrence River. The public water supply of the Village of Malone serves a population of 13,200 (U.S. EPA SDWIS database), which includes three...

Denali National Park Geohazards Geologic Mapping

Denali National Park (DENA) is a major draw for tourism and recreation and a major economic engine for central Alaska. However, the geologic forces that created the steep landscape of DENA also make it prone to geologic hazards (geohazards) like landslides, debris flows, and earthquakes. DENA has only one major road, called the ‘Park Road’, that serves nearly all of its infrastructure.

Salmon River Mountains Legacy Mining Studies

The objective of this study is to characterize the regional impact of legacy mining in the context of framework geology for the Salmon Mountains in central Idaho. This objective is addressed through three interrelated tasks: 1) framework geology, 2) watershed biogeochemical processes, and 3) characterization of trace metals in colloids (fine particles suspended in water).
