Fundamental knowledge of the land and its resources is a basic need for effective government and a productive economy in any nation. The U.S. Geological Survey (USGS), celebrating its 135th birthday on March 3rd, serves our Nation by providing reliable scientific information that can be used in many different ways: to describe and understand the Earth; to minimize loss of life and property from natural disasters; to manage water, ecosystem, energy, and mineral resources; and to enhance and protect our quality of life.
A legacy of science for the Nation
Using science to understand our natural heritage is at the core of the USGS. It can even be traced in our pre-history. More than 200 years ago, the first government survey of the natural resources of the American West, Lewis and Clark’s Corps of Discovery (1804-06), was commissioned by President Thomas Jefferson and funded by Congress. In carrying out Jefferson’s detailed instructions in regard to cartography and scientific goals, the explorers mapped every twist and turn of the Missouri and the Columbia rivers, gathering information about the soils, plants, animals, and native inhabitants of the lands through which they passed.
In 1867, shortly after the Civil War ended, Congress authorized the first of a series of major western explorations that were led by Clarence King (USGS first director), F. V. Hayden, George Wheeler, and John Wesley Powell (USGS second director). On March 3, 1879, the 45th Congress and President Hayes agreed to promote governmental economy and efficiency by discontinuing the three ongoing geological and geographical surveys and replacing them with a U.S. Geological Survey. They made the new organization responsible for the scientific “classification of the public lands and examination of the Geological Structure, mineral resources and products of the national domain.”
Through 135 years the USGS has evolved from a small group of scientists and surveyors who provided guidance on how to describe and manage the public lands of the West to a leading Federal science agency that conducts research and assessment activities on complex natural resource and science issues at scales ranging from local to global.

The Survey today
The institutional strength of the modern USGS is the broad array of science expertise we have. The USGS operates programs that include natural hazards research, such as our earthquake, volcano, and landslide programs; a network of 8,000 streamgages that monitor water availability and help in forecasting floods; and other programs that investigate invasive species, wildlife disease, and climate change.
We have nearly 9,000 science and science-support staff at work at more than 400 USGS science centers across the Nation. The USGS leverages its resources and expertise in partnership with more than 2,000 agencies of State, local and tribal government, the academic community, other Federal partners, non-governmental organizations, and the private sector.
The Survey does not manage any land or resources or have regulatory responsibilities. Our priority is our “boots on the ground” scientists who work with sophisticated monitoring networks to study our world and its natural processes. Our entire focus is on providing objective, ready-to-work science that decision-makers need to face difficult, multi-faceted issues.
The Survey conducts vital resource assessments for energy and mineral potential. We also conduct research on the environmental and human health impacts of the production and use of various energy resources. The USGS is the sole Federal source of scientific information and research on nonfuel mineral potential, production, and consumption, as well as on the environmental effects of the extraction and use of mineral resources. To support the development of economic and national security policies in a global context, the USGS collects and analyzes data on essential mineral commodities from around the world.
USGS maintains the National Earthquake Information Center (NEIC) whose mission is to rapidly determine the location and size of all destructive earthquakes worldwide and to immediately disseminate this information to concerned national and international agencies, scientists, and the general public.
We’re the largest civilian mapping agency. Furthermore, we continuously observe the Earth through the Landsat satellite program in partnership with NASA. The latest satellite, Landsat 8, launched in February 2013, has performed spectacularly in its first year in space.

With historical data comes increased perspective
Historical datasets that have been meticulously collected and archived by the Survey provide a critical context for the current state of natural systems as well as for discerning human influences on the environment. Some of these long-term USGS datasets include borehole temperature records in Alaskan permafrost; streamgage readings for over a century in several locations; over four decades of global change observations from Landsat satellites; catalogs of historical earthquakes and historical data from the Global Seismic Network; and paleoclimate records gleaned from ice cores and seafloor samples.
With historical records like these, in combination with cutting-edge research in paleogeology and chemical analysis, USGS scientists can look far back in time — across decades and centuries, in some instances; in other cases, even millions of years — to understand the global climate conditions of a certain age. This wealth and breadth of data provides an invaluable framework for understanding climate and environmental changes that are taking place today.

Data in demand
Public demand for USGS scientific findings and data is strong and growing stronger. The International Energy Agency has said of us, “The most widely respected source of information on global conventional oil and gas resources is the U.S. Geological Survey.” A May 2012 article in a respected international journal found that the U.S. Geological Survey is the most cited institution in the world for environmental science.
Other broad sectors of the public and the emergency response community have come to rely on USGS for timely, robust, reliable hazard information. For example, USGS supplies rapid assessments of earthquake fatalities and economic losses; real-time flood inundation mapping to support emergency response; predictions of coastal impacts from hurricanes 48 hours prior to hurricane landfall; debris-flow susceptibility maps; rapid notification of the onset of a volcanic eruption at high-threat volcanoes; and real-time wildfire condition information to support fire fighters.
The Road Ahead
Today, with the world population at more than 7 billion and projected to grow to 9 billion by 2040; with competing priorities to balance – for the economy, for the environment, for public health and safety; with the serious, perhaps irreversible consequences of climate change and sea-level rise to consider, our leaders need scientific information about the land and its resources that they can trust with the greatest confidence to guide their decisions.
Building on a rich heritage of 135 years of impartial science for the Nation, the USGS looks forward to applying the breadth and depth of its scientific capabilities, along with the determined commitment of its employees, to the challenges ahead.
