Total Organic Carbon Enrichment and Source Rock Evaluation of the Lower Miocene Rocks Based on Well Logs: October Oil Field, Gulf of Suez-Egypt
Total Organic Carbon Source Rocks Well Logs October Oil Field Gulf of Suez
2013/3/11
October oil field is one of the largest hydrocarbon-bearing fields which produces oil from the sand section of the Lower Miocene Asl Formation. Two marl (Asl Marl) and shale (Hawara Formation) section...
Enrichment of Phosphate on Ferrous Iron Phases during Bio-Reduction of Ferrihydrite
Phosphate Iron Reduction Ferrihydrite Ferrous Iron Vivianite
2013/3/7
The reduction of less stable ferric hydroxides and formation of ferrous phases is critical for the fate of phosphorus in anaerobic soils and sediments. The interaction between ferrous iron and phospha...
Spring molybdenum enrichment in scallop shells: a potential tracer of diatom productivity in temperate coastal environments (Brittany, NW France)
Spring molybdenum enrichment scallop shells diatom productivity temperate coastal environments
2010/1/21
Skeletal molybdenum/calcium ([Mo]/[Ca])shell ratios were examined in shells of the Great Scallop Pecten maximus collected in temperate coastal environments of Western Europe (42 to 49° N). These ratio...
Natural iron enrichment around the Antarctic Peninsula in the Southern Ocean
Natural iron enrichment the Antarctic Peninsula the Southern Ocean
2010/1/21
In the Bransfield Strait, representing a mixture of waters from the Weddell Sea and the Antarctic Circumpolar Current (ACC), concentrations of DFe were ~0.4 nM and of TaLFe ~1.7 nM. The highest concen...
Natural iron enrichment around the Antarctic Peninsula in the Southern Ocean
Natural iron enrichment Antarctic Peninsula Southern Ocean
2010/1/7
As part of the US-AMLR program in January-February of 2006, 99 stations in the South Shetland Islands-Antarctic Peninsula region were sampled to understand the variability in hydrographic and biologic...
CO2 enrichment increases nutrient leaching from model forest ecosystems in subtropical China
CO2 enrichment nutrient leaching model forest ecosystems subtropical China
2010/1/18
The effect of high atmospheric CO2 concentrations on the dynamics of mineral nutrient is not well documented, especially for subtropical China. We used model forest ecosystems in open-top chambers to ...
Climate-driven enrichment of pollutants in peatlands
Climate-driven enrichment pollutants peatlands
2010/1/14
Peatlands play an important role for global carbon dynamics, acting as a sink or source depending on climate. Such changes imply a series of additional effects because peatlands are also an important ...
Nitrogen assimilation and short term retention in a nutrient-rich tidal freshwater marsh – a whole ecosystem 15N enrichment study
Nitrogen assimilation short term retention nutrient-rich tidal freshwater marsh
2010/1/14
An intact tidal freshwater marsh system (3477 m2) was labelled by adding 15N-ammonium as a tracer to the flood water inundating the ecosystem. The appearance and retention of 15N-label in different ma...
Effects of free atmospheric CO2 enrichment (FACE),N fertilization and poplar genotype on the physical protection of carbon in the mineral soil of a polar plantation after five years
free atmospheric CO2 enrichment N fertilization poplar genotype physical protection
2010/1/13
Free air CO2 enrichment (FACE) experiments in aggrading forests and plantations have demonstrated significant increases in net primary production (NPP) and C storage in forest vegetation. The extra C ...
