National Geochemical Database
Project Objectives
The broad objective of this project was to maintain and enhance the National
Geochemical Database (NGDB).
The NGDB
consists of 1) the original RASS and PLUTO data
from the USGS labs, which are now
stored in a common format under the ORACLE relational database management system;
2) the NURE data, which were reformatted and reside currently on the following
web site: see http://pubs.usgs.gov/of/1997/ofr-97-0492/ where
downloads may be made on the basis of 1:250000-scale quadrangles; and 3) the
newly generated data (approximately 1996 - present) which reside on the Laboratory
Information Management System. The enhancements to the NGDB will
enable both USGS scientists and external
customers to more easily extract immediately useable data on a national, regional,
and local scale to help establish a baseline for the abundance and spatial distribution
of chemical elements in the Earth's surficial materials. Specific short-term
objective included:
- Linking the newly developed ORACLE-based database to the Laboratory Information Management System (LIMS)
to provide for the smooth transfer of newly generated data from the LIMS to the NGDB.
- Implement the new Sample Submittal Information procedure on a nationwide basis throughout the USGS. This
procedure has only been implemented at this time (June 2002) in the Central Region. Without this new system in place,
it is possible that more errors and omissions regarding the nature and location of samples may be generated.
- Complete the re-formatting of the NURE HSSR database based on 1:250000-scale quadrangles, compile the
quadrangle-based data into one large data set, and provide these data to the public via a web site and CD/DVD.
- Complete the upgrading of archival USGS geochemical data for Alaska and release these to the public via a web site
and CD/DVD.
- Initiate the upgrading of the remainder (non-Alaska) portion of the USGS-generated data.
- Generate subsets of the master databases containing data in a format more useful to geochemists so they do not
have to wade through the process of extracting the data they need from the entire database.
- Communicate and coordinate the work within this Project with other data delivery efforts within the Bureau such as
NatWeb, GEODE, and Spatial Data Delivery.
- Produce map representations of the database showing the spatial variation of chemical species throughout the
nation and within sub-regions that are of priority to the USGS.
Relevance & Impact
An accurate, easily accessible geochemical database containing multi-element
information on the surficial materials of the nation is vital if the USGS is
to respond quickly to earth science issues raised by Congress and land management
and environmental protection agencies. A nationally consistent geochemical
database provides baseline information on the natural abundance and spatial
variation of chemical elements to which changes caused by agricultural and
irrigation practices, waste disposal, urbanization, industrial pollution, mineral
exploration and mining activities, environmental remediation and restoration
activities, and other land-use practices can be compared. Human-induced chemical
changes to the environment are superimposed on a variable natural geochemical
background where trace-element abundances can range over several orders of
magnitude within short distances. These variations are inadequately documented
and their existence is often overlooked in the setting of public policy. Important
aspects of change cannot be measured, or their consequences anticipated, unless
the present composition of the earth's surface materials is known. In her 2000
Presidential address to the Geological Society of America, Mary Lou Zoback identified
six "grand challenges in earth and
environmental science". The first of these was "recognizing the signal within
the natural variability". Zoback stated that
"documenting and understanding natural variability is a vexing topic in almost
every environmental problem. How do we recognize and understand changes in natural
systems if we don't understand the range of baseline values?" Preserving
and enhancing the vast amount of geochemical data within the Mineral Resources Program's (MRP)
databases will provide a powerful tool for addressing this "grand challenge".
The ultimate goal of producing and electronically disseminating the vast amount
of geochemical data within MRP's
databases directly supports many of the goals and objectives as stated in the
1999 Science Strategy of the Geologic Division. These
databases are essential for understanding the relationship between geologic processes
and human health, ecosystem structure and function, and the distribution of energy
and mineral resources. This project also serves as the focal point of requests
for geochemical data from outside customers. From June 2001 through May 2002,
over
100 requests for data were received from Federal, state, and local government
clients; private sector clients; and internal USGS clients.
