ENVS 3000 - Environmental Geology

Created by the UNC Department of Geology to assist students in identifying rocks and minerals in thin-section.

BISON is a product of the U.S. Geological Survey's Core Science Analytics and Synthesis Program. BISON in and information system that allows users to access, explore, and download U.S. species occurrence data from participating data providers.

Download of 1000 x 1000 pixel images is free for all non-commercial use

The CFWSC has an active presence in support of hydrologic research and monitoring across the Florida, Puerto Rico, and the U.S. Virgin Islands region.

Allows you to retrieve and synthesize geological and geophysical information about large areas of the earth's surface and interior.

Provides access to thousands of online environmental resources

The U.S. Environmental Protection Agency's (EPA) broad mission is to protect human health and the environment.

Links to resources, publications and announcements.

Geology Search Engine: "A Google search that gives moderate preference to hundreds of hand-selected websites by worldwide geological surveys, universities, professors, geologists, geological societies, government agencies, companies and other sources that we believe are reliable."

The ICS Chart is a hierarchy of chronostratigraphic units (e.g. Systems, Series, and Stages) on which geochronological units (e.g. Periods, Epochs, and Ages) are based.

The Mineralogy Database contains 4,714 individual mineral species descriptions with links and a comprehensive image library.

This is a database of the Geologic Maps produced by the United Staes Geological Survey. The website is maintained by the USGS in association with the Association of American State Geologists.

Our National Water Quality Laboratory (NWQL) priority is to continue the important work of the Department of the Interior and the USGS, while also maintaining the health and safety of our employees and community.

The Wetlands mapper is designed to deliver easy-to-use, map like views of America’s Wetland resources. It integrates digital map data along with other resource information to produce current information on the status, extent, characteristics and functions of wetlands, riparian, and deepwater habitats. The Wetland Mapper fulfills the U.S. Fish and Wildlife Service’s strategic plan for the development, revision and dissemination of wetlands data and information to resource managers and the public. This information is intended to promote the understanding and conservation of wetland resources through discovery and education as well as to aid in resource management, research and decision making.

Science.gov searches over 60 databases and over 2,200 scientific websites to provide users with access to more than 200 million pages of authoritative federal science information including research and development results.

Promotes the state geological surveys as sources of important geoscience data to address local, state, and national issues. Site includes a US map with links to all the state surveys.

Provides soil data and information produced by the National Cooperative Soil Survey.

Federal source for science about the Earth, its natural and living resources, natural hazards, and the environment.

The National Map is a collaborative effort among the USGS and other Federal, State, and local partners to improve and deliver topographic information for the Nation.

The Pubs Warehouse provides access to over 170,000 publications written by USGS scientists over the century-plus history of the bureau.

A searchable database of photographs and information about the minerals, gems and gemstones of the collection, over 6300 in all, and information about the collection and the Vargases are accessible here. Gem and mineral specimens, comprising over 3700 single crystals, twinned crystals, crystal clusters and crystal intergrowths, are searchable by mineral and varietal name, color, and crystal shape/habit. The 2600+ Gemstones of the collection, both faceted and in cabachon, can also be searched by mineral/variety name and color, as well as by the type and pattern of cut. Specimens are also grouped into searchable sub-collections. These include mineral psuedomorphs, quartz with inclusions, twinned crystals, synthetic gems, a “thumbnail” collection, and quartz gemstones cut to demonstrate the patterns in three Vargas books on faceting diagrams.

Serving water scientists, engineers, and librarians since 1996.
