Abstract

The perturbation of the global nitrogen cycle is one of the most significant human influences on the marine environment, and is exacerbated by growing human populations along the coast.  As we drastically, and potentially irreversibly, alter the global nitrogen cycle, many basic questions about the microbes driving it remain unanswered.  This talk will discuss how molecular biology and stable isotope geochemistry can be combined to discover new microbial metabolisms, track microbial activity in the ocean, and inform predictions of how microbes will respond to a changing ocean.
