04 Feb, 08 AM - 12 Feb, 02 PM

Following previous installment of soil collars, this trip I plan to take measurements of soil trace gas fluxes (specifically, CO2, N2O, and NOx emissions) during wet-up and dry-down conditions. Using experimental water treatments which either contain only DI water or a mixture of DI water + dissolved nitrogen, I will add treatments to soils within soil collars and track gas fluxes using a network of chambers and instruments. I will also collect soil samples to analyze changes in soil chemistry and microbial communities at various timepoints throughout the 48-hour wetup-drydown process. Because of equipment limitations, I will only be manipulating water+nitrogen collars for the first half of the study period and water-only collars during the second half of the study period. Including setup and teardown of equipment, this winter campaign should take approximately a week. On Friday, Bob Johnson and I will fly an unmanned aerial vehicle ("drone") in a 30meter x 30meter grid over the study site to remotely assess aboveground vegetation biovolume. Flight will take place ~100 feet above the ground at midday Thursday.
