Major deep carbon sink linked to microbes at volcanic island chains（图）
deep carbon sink microbes volcanic island chains
2019/11/22
As much as 19 percent more carbon dioxide than previously believed is removed naturally and stored deep underground in seafloor trenches near island chains of volcanoes, according to a study in the jo...
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...
Denitrification alternates between a source and sink of nitrous oxide in the hypolimnion of a thermally stratified reservoir
Denitrification alternates sink of nitrous oxide
2014/4/2
Nitrogen loading from developed watersheds to aquatic ecosystems can stimulate microbial denitrification, a
process that reduces nitrate (NO{

) to dinitrogen (N2) or nitrous oxide (N2O), the latt...
The Surface of the Sea is a Sink for Nitrogen Oxides at Night（图）
Nitrogen Oxides Sink Surface
2014/3/20
The surface of the sea takes up nitrogen oxides that build up in polluted air at night, new measurements on the coast of southern California have shown. The ocean removes about 15 percent of these che...
Counting Unique-Sink Orientations
unique-sink orientation linear complementarity problem pivoting Pmatrix
2011/1/19
Unique-sink orientations (USOs) are an abstract class of orientations of the ncube graph. We consider some classes of USOs that are of interest in connection with the linear complementarity problem. W...
Modeling branching effects on source-sink relationships of the cotton plant
Functional-structural model Parameter optimization Source-sink relationship
2011/2/21
Compared with classical process-based models,the functional-structural plant models provide more efficient tools to explore the impact of changes in plant structures on plant functioning.

Heterogeneous uptake of gaseous hydrogen peroxide by Gobi and Saharan dust aerosols: a potential missing sink for H2O2 in the troposphere
gaseous hydrogen peroxide Gobi and Saharan dust aerosols H2O2 the troposphere
2010/8/16
The first direct laboratory measurements of gaseous hydrogen peroxide uptake by authentic Gobi and Saharan dust aerosol particles as a function of relative humidity (RH) have been carried out in an en...
Aerobic respiration and hypoxia in the Lower St. Lawrence Estuary: Stableisotope ratios of dissolved oxygen constrain oxygen sink partitioning
Aerobic respiration and hypoxia Lawrence Estuary dissolved oxygen constrain oxygen sink partitioning
2014/4/17
We measured the concentration and the stable isotope ratios of dissolved oxygen in the water column in the Estuary and Gulf of St. Lawrence to determine the relative importance of pelagic and benthic ...
Technical Note: Measuring condensation sink and ion sink of atmospheric aerosols with the electrical low pressure impactor (ELPI)
condensation sink ion sink atmospheric aerosols ELPI
2010/2/21
We investigate the suitability of ELPI for condensation sink and ion sink measurements. The aim is to find the simple calibration factors by which the measured ELPI current can be converted to condens...
Flows driven by a combination of source/sink part 2: Interior creeping flows
Flows driven combination source sink
2010/9/15
In this paper, two-dimensional creeping flows generated by source and sink inside a circular cylinder are studied in the presence of different boundary conditions. For simplicity, line source and sink...
Flows driven by a combination of source/sink part 1: Exterior creeping flows
Flows driven combination source sink
2010/9/15
In this paper, the two-dimensional creeping flows outside a circular cylinder induced by source/sink with various boundary conditions is studied.
A young afforestation area in Iceland was a moderate sink to CO2 only a decade after scarification and establishment
A young afforestation area Iceland a decade after scarification and establishment
2010/1/21
This study reports on three years (2004–2006) of measurements of net ecosystem exchange (NEE) over a young Siberian larch plantation in Iceland established on previously grazed heathland pasture that ...
Oxidation of SO2 by H2O2 on ice surfaces at 228 K: a sink for SO2 in ice clouds
SO H2O2 ice surfaces SO2 ice clouds
2009/3/12
The heterogeneous reaction SO2 + H2O2 H2SO4 on ice at 228 K has been studied in a low temperature coated-wall flow tube. With H2O2 in excess of SO2, the loss of SO2 on an ice surface is time depende...
