Sink or link? The bacterial role in benthic carbon cycling in the Arabian Sea's oxygen minimum zone [PDF]

Biogeosciences, 2013
The bacterial loop, the consumption of dissolved organic matter (DOM) by bacteria and subsequent transfer of bacterial carbon to higher trophic levels, plays a prominent role in pelagic food webs.

Relating hygroscopicity and composition of organic aerosol particulate matter [PDF]

, 2010
A hygroscopicity tandem differential mobility analyzer (HTDMA) was used to measure the water uptake (hygroscopicity) of secondary organic aerosol (SOA) formed during the chemical and photochemical oxidation of several organic precursors in a smog chamber.

Challenges in modelling dissolved organic matter dynamics in agricultural soil using DAISY [PDF]

, 2008
Because dissolved organic matter (DOM) plays an important role is terrestrial C-,N-and P-balances and transport of these three components to aquatic environments, there is a need to include it in models.

Seasonal dynamics of carbon and nutrients from two contrasting tropical floodplain systems in the Zambezi River basin [PDF]

Biogeosciences, 2015
Floodplains are important biogeochemical reactors during fluvial transport of carbon and nutrient species towards the oceans. In the tropics and subtropics, pronounced rainfall seasonality results in highly dynamic floodplain biogeochemistry. The massive
