Environmental isotopes
(and related tracers) have a wide variety of applications in hydrology,
geology, and biology. Some isotopes can be used as tracers of water, nutrient,
or solute sources. Others are studied to gain insight into natural
processes taking place in various environmental settings. To increase the
awareness of isotope applications among the hydrologists, geochemists, and
biologists within the USGS, several sets of web pages have been assembled:

An
image map periodic
table has been created to help illustrate the uses of assorted isotopes
in hydrology, geology, and biology. More thorough contributions are very
welcome. NOTE: you must use a graphics-capable browser to view the
image map; otherwise, you must use the alternative
access page.

A publications page
containing lists of isotope-related publications has also been assembled.
These pages include a brief review of the fundamentals of isotope geochemistry,
listings of important reference books and chapters, and excerpts from
on-line isotope hydrology books.

A resources page has
been compiled to provide additional materials, including listings of
events, several sets of isotope-related references, a simple search
engine for references, links to other isotope-related on-line resources,
etc.
