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

2014/3/20
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...

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
font style='font-size:12px;'>
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)
