The topical directory below provides an alternate way to browse USGS science programs and activities. Explore within each topic by data, news, images, video, social media, and much more. 

Biology and Ecosystems

Biology and Ecosystems

Learn more about the science of conducting research and monitoring to understand freshwater, terrestrial and marine ecosystems and the fish and wildlife within them.
Climate and Land Use Change

Climate and Land Use Change

This science includes the long-term alteration in the characteristic weather conditions of a region, such as changes in precipitation and temperature.
Coasts

Coasts

Science and information to better understand coastal-change processes in order to restore and protect coastal resources as well as manage the natural hazards and impacts of climate and land-use change on coastal communities and ecosystems. We provide relevant tools and information needed to make our Nation’s coasts healthy and resilient.
Data, Tools, and Technology

Data, Tools, and Technology

These resources include aerial photography, data management, elevation data, geospatial datasets, satellite imagery, risk assessments, and more.
Energy

Energy

This science includes the processes critical to the formation, accumulation, occurrence, and alteration of geologically based energy resources, robust assessments of those resources, and the study of the impact of energy resource occurrence and/or production and use on both environmental and human health.
Environmental Health

Environmental Health

Environmental health science focuses on the interface between health and the environment, where interactions among people, the environment, and other living organisms affect the risk of toxicologic and infectious disease.
Geology

Geology

USGS Geology efforts address major societal issues that involve geologic hazards and disasters, climate variability and change, energy and mineral resources, ecosystem and human health, and ground-water availability.
Mapping, Remote Sensing, and Geospatial Data

Mapping, Remote Sensing, and Geospatial Data

Remote Sensing is the acquiring of information about a natural feature or phenomenon, such as the Earth's surface, without actually being in contact with it. USGS remote sensing is usually carried out with airborne or space-borne sensors or cameras. Geospatial analysis is the detailed study of information such as measurements, counts, and computations as a function of geographical location.
Minerals

Minerals

The study of minerals includes all natural occurrences of useful inorganic elements or compounds. Learn more about the occurrences, quality, quantity, and availability of mineral resources with links to projects, publications, spatial data, teams, issues, and news.
Natural Hazards

Natural Hazards

Natural hazard science is the study of coastal and marine geology, earthquake hazards, geomagnetism, landslides, volcanoes, seismological and geophysical sensors, floods, droughts, tsunamis, hurricanes, and storms.
Oceans

Oceans

USGS coastal and marine geologic research supports understanding of coastal and marine environments, through technology, tools, data and mapping products.
Planetary Science

Planetary Science

Scientific study of the solid bodies of the solar system, including planets, moons, asteroids, meteorites, and interplanetary materials.
Water

Water

Explore real-time and historical data, including surface water, groundwater, water quality, water use data, flood and drought conditions, and much more. View our tools to find, understand, and work with our data and information.
