Rates of biogeochemical phosphorus and copper redistribution in young floodplain soils
biogeochemical phosphorus copper redistribution young floodplain soils
2010/1/21
Nutrients and trace metals in river-floodplain systems may originate from anthropogenic activities and/or geogenic sources. Here, we analyze a soil chronosequence (2 to approximately 600 years) on a f...
Phosphatase activity and organic phosphorus turnover on a high Arctic glacier
Phosphatase activity organic phosphorus high Arctic glacier
2010/1/20
Arctic glacier surfaces harbour abundant microbial communities consisting mainly of heterotrophic and photoautotrophic bacteria. The microbes must cope with low concentrations of nutrients and with th...
Phosphorus burial in the ocean over glacial-interglacial time scales
Phosphorus burial ocean glacial-interglacial time scales
2010/1/19
The role of nutrients, such as phosphorus (P), and their impact on primary productivity and the fluctuations in atmospheric CO2 over glacial-interglacial periods are intensely debated. Suggestions as ...
Deposition of nitrogen and phosphorus on the Baltic Sea:seasonal patterns and nitrogen isotope composition
nitrogen phosphorus Baltic Sea seasonal patterns nitrogen isotope composition
2010/1/18
Atmospheric deposition of nitrogen and phosphorus on the central Baltic Sea (Baltic Proper) was estimated monthly at two coastal stations and two isolated islands in 2001 and 2002. Yearly nitrogen dep...
Modeling the impact of iron and phosphorus limitations on nitrogen fixation in the Atlantic Ocean
impact of iron phosphorus limitations nitrogen fixation Atlantic Ocean
2010/1/14
The overarching goal of this study is to simulate subsurface N* (sensu, Gruber and Sarmiento, 1997; GS97) anomaly patterns in the North Atlantic Ocean and determine the basin wide rates of N2-fixation...
Application of two phosphorus models with different complexities in a mesoscale river catchment
two phosphorus models different complexities a mesoscale river catchment
2010/1/27
The water balance and phosphorus inputs of surface waters of the Weiße Elster catchment, Germany, have been quantified using the models GROWA/MEPhos and SWAT. A comparison of the model results s...
The global marine phosphorus cycle:sensitivity to oceanic circulation
global marine phosphorus cycle: sensitivity oceanic circulation
2010/1/14
A new mass balance model for the coupled marine cycles of phosphorus (P) and carbon (C) is used to examine the relationships between oceanic circulation, primary productivity, and sedimentary burial o...
Seasonal cycling of phosphorus in the Southern Bight of the North Sea
Seasonal cycling phosphorus Southern Bight North Sea
2010/1/12
We have investigated the seasonal cycle of nutrients, chlorophyll a, dissolved organic nitrogen (DON), and dissolved and particulate organic carbon (DOC and POC) for 10 stations in the Belgian coastal...
