Application of nitrogen stable isotopes to identify sources of nutrient pollution : a management tool?

Creator:

Redon, Elizabeth A.

Abstract:

Nutrient pollution may perhaps be one of the oldest water quality problems and has recently been considered as one of the greatest threats to estuarine and coastal waters. Excessive nutrient loads have had a vast array of impacts on estuarine and coastal ecosystems globally. Direct negative effects include: shading out...

Capabilities of Detecting Medical Isotope Facilities through Radioxenon Sampling

Creator:

MacDougall, Matthew R.

Abstract:

Medical Isotopes are a necessity in modern medicine for cancer treatments and medical imaging. In order to ensure that the needs and demands are met for the medical procedures, facilities are put in place to produce these isotopes. There are over 25 different isotopes of interest being produced by more...

A stable carbon isotope approach to distinguish climate stress from other imposed stresses in coniferous forests

Creator:

Panek, Jeanne A.

Abstract:

To understand the effect of human-induced stresses on forests, there is a need for a method to separate effects of imposed stress from effects of natural climate stress. I developed an approach to predict forest response to climate stress using as indicators stable carbon isotopes in tree foliage and growth-rings....
