Nitrogen dynamic in running waters at high altitude in the Khumbu Valley, Nepal Hymalaya

Two sampling campaign were carried on in 2007 and 2008 in order to collect running water samples from high elevation zone (4500-5500 m asl) in the Sagarmatha National Park. The water samples will be analyzed for the main nitrogen species (N-NO3, N-NH4, TN) and for the principal hydro-chemical constituents (Ca, Mg, Na, K, Cl, SO4, HCO3). The concentration and the temporal variation of nitrogen species were related to the N concentration of lakes and to the fluxes of wet deposition from the same area.

Purpose
The overall purpose of this research is the study of the hydrological and biological processes controlling the nitrogen cycling in the Himalayan alpine ecosystem. As this region represents one of the most remote and uncontaminated site in the world, the results of this study could be very useful to understand the phenomenon occurring in the Alps, in relation to the climate changes too

You can customize the template to suit your needs. You can add and remove fields and fill out default information (e.g. contact details). Fields you can not change in the default view may be accessible in the more comprehensive (and more complex) advanced view. You can even use the XML editor to create custom structures, but they have to be validated by the system, so know what you do :-)
