Biogeochemical consequences of vertical and lateral transport of particulate organic matter in the southern North Sea: A multiproxy approach [PDF]

open access: yes, 2015
Vertical and lateral transports are of importance in continental shelf systems such as the North Sea andplay a major role in the processing of organic matter.

Utilization of ancient permafrost carbon in headwaters of Arctic fluvial networks [PDF]

open access: yes, 2015
Northern high-latitude rivers are major conduits of carbon from land to coastal seas and the Arctic Ocean. Arctic warming is promoting terrestrial permafrost thaw and shifting hydrologic flowpaths, leading to fluvial mobilization of ancient carbon stores.

Exploratory analysis of excitation-emission matrix fluorescence spectra with self-organizing maps as a basis for determination of organic matter removal efficiency at water treatment works [PDF]

open access: yes, 2009
In the paper, the self-organizing map (SOM) was employed for the exploratory analysis of fluorescence excitation-emission data characterizing organic matter removal efficiency at 16 water treatment works in the UK.

Isolation and characterization of bis(silylene)-stabilized antimony(I) and bismuth(I) cations

open access: yesNature Communications, 2023
Monovalent group 15 cations L2Pn + (L = σ-donor ligands, Pn = N, P, As, Sb, Bi) have attracted significant experimental and theoretical interest because of their unusual electronic structures and growing synthetic potential.

Study of the trace metal ion influence on the turnover of soil organic matter in cultivated contaminated soils [PDF]

open access: yes, 2006
The role of metals in the behaviour of soil organic matter (SOM) is not well documented. Therefore, we investigated the influence of metals (Pb, Zn, Cu and Cd) on the dynamic of SOM in contaminated soils where maize (C4 plant) replaced C3 cultures. Three

Natural organic matter - The relationship between character and treatability [PDF]

open access: yes, 2004
The characterisation and treatment of natural organic matter are becoming more important to the water utilities in the UK and around the world. This paper looks at the relationship between bulk and fractionated organic material and the performance of ...

Challenges in modelling dissolved organic matter dynamics in agricultural soil using DAISY

open access: yes, 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.

Enhanced rates of particulate organic matter remineralization by microzooplankton are diminished by added ballast minerals [PDF]

open access: yes, 2013
To examine the potentially competing influences of microzooplankton and calcite mineral ballast on organic matter remineralization, we incubated diatoms in darkness in rolling tanks with and without added calcite minerals (coccoliths) and ...
