Resources on Isotopes

Selected on-line presentations about the use of isotopes to trace sources of nitrate and organic matter in ecosystems

Here are links to several on-line presentations.

• CUAHSI seminar in April 2005 about tracing sources of organics and nutrients in watersheds (click on the Kendall link further down on the page).

• USGS seminar in May 2005 about tracing causes of hypoxia (click on the Kendall link further down on the page).

• EPA seminar about tracing agricultural contaminants with isotopes given at an EPA workshop on Animal Feeding Operations (AFOs) in December 2004 (click on the Kendall link further down on the page).

• Handouts about nitrate isotopes for CA GRA isotope short-course (March 2007)
