Phragmites australis, also known as common reed, is a native North American wetland grass that has grown in North America for thousands of years. More recently, a nonnative, invasive variety of Phragmites from Eurasia is rapidly invading wetlands across the continental United States and other parts...

Unconsolidated deposits of sand, silt, clay, and gravel compose the principal aquifer in Greeley and Wichita Counties. The deposits are as much as 300 feet (91 m)2/thick, of which as much as 145 feet (44 m) is saturated. In 1972, there were about 1,040 large-capacity wells--yielding 100 gallons per...

The Hawthorn Formation in northeastern Florida consists of widely varying mixtures of clay, quartz sand, carbonate and phosphate. Phosphate is virtually ubiquitous throughout the Hawthorn sediments and occurs primarily as allochemical grains. The carbonate component consists predominantly of...

The Maryland Port Administration has proposed to install a Confined Aquatic Disposal (CAD) cell at the Masonville vessel berth for the containment of dredge materials from Baltimore Harbor. Construction of the CAD cell requires excavation of predominantly sandy sediment from the Patapsco Formation...
2008, Maryland Geological Survey
Six exploratory test wells were drilled in Southern Maryland to obtain hydrogeologic data for the Upper Patapsco and Lower Patapsco aquifers. Information collected from the test wells includes lithologic descriptions of sediments; biostratigraphic analyses using fossil pollen, spores, and plankton...
1995, Arizona Geological Survey
This summary report overviews a State of Arizona and U. S. Department of Energy funded drilling project to determine if near-term hot dry rock (HDR) geothermal potential exists in the eastern portion of the White Mountains region of Arizona. A 4,505 feet deep slim-hole exploratory well, Alpine1/...
2001, Arizona Geological Survey
The banded crystalline rocks of Sabino Canyon are a strong aesthetic component of the canyon's dramatic views. Certainly these rocks have attracted much attention from geologists. Until recently they were much-debated but poorly understood. When finally decoded (for example, Davis, 1980),...
1963, Arizona Geological Survey
Compressed air is a very important source of power in nearly all mines. In fact, no real substitute has been found for compressed air as a source of power for drilling holes for blasting in underground mining. Moreover, compressed air is used for many other purposes in and around the mine. Mucking...

White-nose syndrome (WNS) is a devastating disease that has killed millions of hibernating bats since it first appeared in New York in 2007 and has spread at an alarming rate from the northeastern to the central United States and Canada. The disease is named for the white fungus Geomyces...

About the Geological Surveys Database

As of July 2018, the Geological Surveys Database replaces the Critical Issues Research Database, providing an improved portal for decision makers and others to locate and comprehensively search state geological survey publications and U.S. Geological Survey factsheets.

The Geological Surveys Database is now an external database that has be integrated into AGI's Critical Issues webpages. To use the entire suite of features of the Geological Surveys Database, please visit

The Geological Surveys Database provides full-text searching of publications meaning that users can not only search metadata fields (i.e., title, author, notes, etc.), but also search against the entire text of the publications in the database in order to find the information they are seeking. The database also features interactive geographic searching of publications that have geographic coordinates, browsing of publications, faceted searching, and more.

Record display views include robust metadata that is based on a combination of GeoRef metadata that is supplemented with additional metadata from the state geological surveys and U.S. Geological Survey, links to state geological survey websites, suggestions for similar items, and a map display of associated geographic metadata coordinates.

The Geological Surveys Database also provides a wide array of user features including the ability to export citations, create user accounts to save queries, citations and create curated lists, add comments and custom tags to records in the database, and more.

The Geological Surveys Database is a collaborative effort between the American Geosciences Institute and U.S. state geological surveys to help increase the discoverability and use of geological survey publications by decision makers as they address issues at the intersection of the geosciences and society.
