Evaluating a Zonal-mean Hydrologic Model Against a Water Tag-enabled Global Simulation

Creator:: Mandovi, Andrew
Abstract:: The hydrologic cycle on Earth comprises the transitions among the solid, liquid, and gaseous phases of water. Understanding the hydrologic cycle is of course important for climate science, but also for agricultural, drinking water, and disaster preparedness purposes. Improvements in satellite observations and general circulation models (GCMs) have led to...

Transcriptome Responses of the Nitrifying Bacteria Nitrosomonas europaea and Nitrobacter hamburgensis to Low Oxygen

Creator:: Dobie, Michael
Abstract:: Nitrification is the process within the global Nitrogen Cycle where ammonia (NH3) is oxidized to nitrate (NO₃⁻) and can be carried out by two distinct groups of bacteria. The ammonia-oxidizing bacteria (AOB) first oxidize NH₃ to nitrite (NO₂⁻), and second, the nitrite-oxidizing bacteria (NOB) oxidize NO₂⁻ to NO₃⁻. In aerobic...
