Denitrification and inference of nitrogen sources in the karstic Floridan Aquifer
(Biogeosciences, 2012-05-22)Aquifer denitrification is among the most poorly constrained fluxes in global and regional nitrogen budgets. The few direct measurements of denitrification in groundwaters provide limited information about its spatial and ... -
Direct and indirect coupling of primary production and diel nitrate dynamics in a subtropical spring-fed river
(Limnology and Oceanography, 2010-03-01)We used high-frequency in situ measurements of nitrate (NO3-) and dissolved oxygen (DO) from the springfed Ichetucknee River, Florida, to derive multiple independent estimates of assimilatory nitrogen (N) demand, and to ... -
Hydrologie and biotic influences on nitrate removal in a subtropical spring-fed river
(Limnology and Oceanography, 2010-01-01)We use a long-term chemical and hydrologic record in combination with longitudinal sampling and highfrequency nitrate (NO3-) measurements from in situ sensors to describe temporal and spatial patterns of nitrogen (N) inputs ... -
Inference of riverine nitrogen processing from longitudinal and diel variation in dual nitrate isotopes
(Journal of Geophysical Research: Biogeosciences, 2012-03-01)Longitudinal and diel measurements of dual isotope composition (δ15N and δ18O) in nitrate (NO<inf>3</inf>-N) were made in the Ichetucknee River, a large (∼8m3 s -1), entirely spring-fed river in North Florida, to determine ...
