Frogs, Mercury, Tracers, and More -- USGS Sponsors Several Special
Sessions at the Fall 2001 American Geophysical Union Meeting
The USGS co-sponsored or sponsored four special sessions at the American
Geophysical Union's (AGU) 2001 Fall Meeting, San Francisco, CA, December
10-14, 2001. The following special sessions covered a wide range of topics
where the latest research from many organizations as well as the Toxic
Substances Hydrology Program was presented.
Special Sessions
In addition to the above special sessions, scientists from the U.S. Geological
Survey's Toxic Substances Hydrology Program gave the following presentations
at the meeting.
