Advection of NH3 over a pasture field and its effect on gradient flux measurements
Advection NH3 pasture field gradient flux measurements
2010/1/20
Deposition of atmospheric ammonia (NH3) to semi-natural ecosystems leads to serious adverse effects, such as acidification and eutrophication. A step in quantifying such effects is the measurement of ...

Quantification of ammonia (NH3) land-atmosphere exchange is required for atmospheric modelling and assessment of nitrogen deposition, yet flux measurement methods remain highly uncertain. To address t...
Particle optical backscattering along a chlorophyll gradient in the upper layer of the eastern South Pacific Ocean
Particle optical backscattering chlorophyll gradient upper layer Pacific Ocean
2010/1/15
The particulate scattering, bp, and backscattering, bbp, coefficients are determined by the concentration and physical properties of suspended particles in the ocean. They provide a simple description...
Note on seismic hazard assessment using gradient of uplift velocities in the Turan block (Central Asia)
seismic hazard assessment gradient uplift velocities Turan block
2009/12/25
Uplift gradients can provide the location of highly strained zones, which can be considered to be seismic. The Turan block (Central Asia) contains zones with high gradient of uplift velocities, above ...
