Hydrologic control of nitrogen removal, storage, and export in a mountainstream
Hydrologic control nitrogen removal storage mountains tream
2014/4/17
Nutrient cycling and export in streams and rivers should vary with flow regime, yet most studies of stream nutrient transformation do not include hydrologic variability. We used astable isotope tracer...
The isotopic and hydrologic response of small, closed-basin lakes to climate forcing from predictive models: Application to paleoclimate studies in the upper Columbia River basin
isotopic hydrologic closed-basin
2014/4/17
Simulations conducted using a coupled lake-catchment, hydrologic and isotope mass-balance model indicate
that small, closed-basin lakes in north-central Washington are isotopically sensitive to chang...
Hydrologic and biotic influences on nitrate removal in a subtropical spring-fed river
Hydrologic biotic influences on nitrate removal a subtropical spring-fed river
2014/4/16
We use a long-term chemical and hydrologic record in combination with longitudinal sampling and highfrequency nitrate (NO{3) measurements from in situ sensors to describe temporal and spatial patterns...
The Relative Influence of Diapycnal Mixing and Hydrologic Forcing on the Stability of the Thermohaline Circulation
Diapycnal Mixing Hydrologic Forcing Thermohaline Circulation
2008/7/11
Scaling analysis of the oceanic thermohaline circulation has been done under two types of surface boundary conditions: (i) Under “relaxation” conditions (sea surface temperature and salinity are relax...
Denitrification and hydrologic transient storage in a glacial meltwater stream, McMurdo Dry Valleys, Antarctica
Denitrifi cation hydrologic transient storage
2014/5/19
In extreme environments, retention of nutrients within stream ecosystems contributes to the persistence of aquatic
biota and continuity of ecosystem function. In the McMurdo Dry Valleys, Antarctica, ...
Hydrologic and hydraulic control of macrophyte establishment and performance in streams
macrophyte establishment streams
2014/5/21
Macrophytes play a key role in many unshaded lotic ecosystems, but little is known of the factors controlling
their presence, abundance, and composition. Macrophyte abundance, diversity, and composit...
Inorganic nitrogen transformations in the bed of the Shingobee River, Minnesota, USA: Integrating hydrologic and biological processes using sediment perfusion cores
Inorganic nitrogen transformations the bed of the Shingobee River Minnesota USA Integrating hydrologic biological processes sediment perfusion cores
2014/5/20
Inorganic N transformations were examined in streambed sediments from the Shingobee River using sediment perfusion cores. The experimental design simulated groundwater-stream water mixing within sedim...
