Determination of organic carbon in soils and sediments in an automatic method
Automatic digestion Soils Sediments Organic carbon
2018/3/23
Our automatic digestion device is applied in determining the quantity of organic carbon in the soils/sediments. Its operation process is simple. The reaction conditions are optimized; the complex pret...
Carbon isotope ratios of organic matter in Bering Sea settling particles: Extremely high remineralization of organic carbon derived from diatoms
diatoms coccolithophores carbon isotope organic carbon remineralization rain ratio
2017/4/10
The carbon isotope ratios of organic carbon in settling particles collected in the highly-diatom-productive Bering Sea
were determined. Wet decomposition was employed to oxidize relatively fresh orga...
The Dissolved Organic Carbon Controversy:An Update
Dissolved Organic Carbon Controversy An Update
2015/8/19
This note is intended as an update on activities to improve the measurement of dissolved organic carbon (DOC) in seawater. The exciting and controversial paper by Sugimura and Suzuki (1988) led to ren...
Simultaneous measurement of the gross and net primary production of the benthic community and the net input of organic carbon delivered by currents to the coral reef flat of the north shore of Moorea,...
Changes in soil organic carbon and nitrogen capacities of Salix cheilophila Schneid along a revegetation chronosequence in semi-arid degraded sandy land of the Gonghe Basin, Tibet Plateau
Republican basin the desert area soil organic carbon
2015/1/6
The Gonghe Basin is a sandified and desertified region of China, but the distribution of soil organic carbon (SOC) and total nitrogen (TN) along the cultivation chronosequence across this ecologically...
Conventional tillage versus organic farming in relation to soil organic carbon stock in olive groves in Mediterranean rangelands (southern Spain)
Conventional tillage organic farming soil organic carbon stock olive groves Mediterranean rangelands
2015/1/6
Soil organic carbon (SOC) concentration is a soil variable subject to changes. The management system is a key factor that influences these changes. To determine the long-term effects of the management...
Grassland fire effect on soil organic carbon reservoirs in a semiarid environment
effect on soil organic carbon emiarid environment
2015/1/5
The aim of this work was to investigate the effect of an experimental fire used for grassland management
on soil organic carbon (SOC) stocks. The study was carried
out on Hyparrhenia hirta (L....
Comparing microbial and chemical kinetics for modelling soil organic carbon decomposition using the DecoChem v1.0 and DecoBio v1.0 models
Comparing microbial chemical kinetics modelling soil organic carbon decomposition DecoChem v1.0 DecoBio v1.0 models
2014/12/19
Soil organic matter is a vast store of carbon, with a critical role in the global carbon cycle. Despite its importance, the dynamics of soil organic carbon decomposition, under the impact of climate c...
Estimating soil organic carbon stocks of Swiss forest soils by robust external-drift kriging
Swiss forest soils robust external-drift kriging
2014/12/18
Accurate estimates of soil organic carbon (SOC)
stocks are required to quantify carbon sources and sinks
caused by land use change at national scale.
Modeling dissolved organic carbon in temperate forest soils: TRIPLEX-DOC model development and validation
Modeling dissolved organic carbon temperate forest soils
2014/12/18
Even though dissolved organic carbon (DOC) is
the most active carbon (C) cycling in soil organic carbon
(SOC) pools, it receives little attention from the global C
budget.
Regional-scale variation of dissolved organic carbon concentrations in Swedish lakes
Organic carbon lakes
2014/10/16
We assessed spatial variability in dissolved organic carbon (DOC) concentrations measured in nearly 2000
Swedish lakes. Inter-lake variance peaked at two different scales, representing within-region ...
Dissolved organic carbon and its carbon isotope compositions in hill slope soils of the karst area of southwest China: Implications for carbon dynamics in limestone soil
karst slope land soil organic carbon dissolved organic carbon δ13C
2017/4/11
Dissolved organic carbon (DOC) can be considered fine indicators of soil quality that influence soil function in specific
ways and are very sensitive to changes in soil management practices. In this ...
Revealing organic carbon sources fueling a coral reef food web in the Gulf of Mexico using stable isotopes and fatty acids
Revealing organic carbon sources coral reef food web Gulf of Mexico stable isotopes fatty acids
2014/4/2
Carbon and nitrogen stable isotopes and fatty acids (FAs) revealed primary producer organic carbon sources that fuel a coral reef food web with river influence. A stable isotope mixing model was used ...
Groundwater-derived dissolved inorganic and organic carbon exports from a mangrove tidal creek: The missing mangrove carbon sink?
Groundwater-derived dissolved inorganic organic carbon exports mangrove tidal creek
2014/4/2
A majority of the global net primary production of mangroves is unaccounted for by current carbon budgets. It has been hypothesized that this “missing carbon” is exported as dissolved inorganic carbon...
