Changes in the vertical distribution of primary production in response to land-based nitrogen loading
Terrestrial nitrogen load production
2014/10/16
Changes in the vertical distribution of primary production in response to land-based nitrogen loading。
Nutrient loading and meteorological conditions explain interannual variability of hypoxia in Chesapeake Bay
Nutrient loading meteorological conditions Chesapeake Bay
2014/4/2
We use geostatistical universal kriging and conditional realizations to provide the first quantitative estimates,
with robust estimates of uncertainties, of the seasonal and interannual variability i...
Assessing nonpoint-source nitrogen loading and nitrogen fixation in lakes using δ15N and nutrient stoichiometry
Assessing nonpoint-source nitrogen loading nitrogen fixation lakes using δ15N nutrient stoichiometry
2014/4/4
Runoff from human-dominated watersheds has greatly altered nitrogen (N) and phosphorus (P) cycling in lakes. Nutrients from human sources are distinct from those from undisturbed ecosystems in several...
Phosphorus loading of mountain lakes: Terrestrial export and atmospheric deposition
Phosphorus loading mountain lakes Terrestrial export atmospheric deposition
2014/4/8
We studied the atmospheric deposition of phosphorus (P) forms along an elevation gradient, and its contribution to the total external P loading of lakes in the Tatra Mountains and the Bohemian Forest,...
Physical and biogeochemical limits to internal nutrient loading of meromictic Lake Kivu
Physical biogeochemical internal nutrient loading meromictic Lake Kivu
2014/4/17
Lake Kivu is one of the large African Rift lakes situated between the Democratic Republic of the Congo and Rwanda. In its permanently stratified hypolimnion, unusually high methane concentrations have...
The effect of increased nitrate loading on nitrate reduction via denitrification and DNRA in salt marsh sediments
increased nitrate nitrate reduction via
2014/4/16
The effects of increased nitrogen loading on denitrification and dissimilatory nitrate reduction to ammonium
(DNRA) in marsh sediments were studied in permanently submerged subtidal creek sediments a...
Capacity of surface warship’s protective bulkhead subjected to blast loading
protective bulkhead blast loading energy method
2011/9/9
The protective bulkhead of the large surface warship need to be designed working in the membrane mode. In this paper, a formula is derived for calculating the plastic deformation of the protective bul...
The Effects of Loading and Self-Attraction on Global Ocean Tides：The Model and the Results of a Numerical Experiment
Self-Attraction Global Ocean Tides Numerical Experiment
2009/3/7
The computation of global tides, including the effects of loading and self-attraction, is formulated. A uniqueness theorem for the solution of the differential and associated finite-difference Problem...
An empirical model describing the seasonal dynamics of phosphorus in 16 shallow eutrophic lakes after external loading reduction
p An empirical model describing phosphorus
2014/4/30
Based on monthly mass balances on 7–8 yr of data from 16 shallow (mean depth: 1–10 m), eutrophic, unstratified,
or only temporarily stratified Danish lakes, we developed a simple empirica...
Terrestrial and aquatic ecosystems are intimately linked by the export of elements from watersheds. Although
export is influenced by land cover within watersheds, few models evaluate how the sp...
