Optical properties and bioavailability of dissolved organic matter along a flow-path continuum from soil pore waters to the Kolyma River mainstem, East Siberia [PDF]

, 2016
The Kolyma River in northeast Siberia is among the six largest Arctic rivers and drains a region underlain by vast deposits of Holocene-aged peat and Pleistocene-aged loess known as yedoma, most of which is currently stored in ice-rich permafrost ...

Technical Note: Comparison of storage strategies of sea surface microlayer samples [PDF]

, 2013
The sea surface microlayer (SML) is an important biogeochemical system whose physico-chemical analysis often necessitates some degree of sample storage.

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.

Oxidation of Aquatic Organic Contaminants Induced by Excited Triplet States

CHIMIA, 2007
The developments of the last fifteen years in the field of triplet-induced degradation of aquatic organic contaminants are reviewed. There is increasing evidence that the elusive excited triplet states of colored dissolved natural organic matter

Nunataryuk field campaigns: understanding the origin and fate of terrestrial organic matter in the coastal waters of the Mackenzie Delta region [PDF]

Earth System Science Data, 2023
Climate warming and related drivers of soil thermal change in the Arctic are expected to modify the distribution and dynamics of carbon contained in perennially frozen grounds. Thawing of permafrost in the Mackenzie River watershed of northwestern Canada,

Sorption and fractionation of dissolved organic matter and associated phosphorus in agricultural soil [PDF]

, 2007
Molibility of dissolved organic matter (DOM) strongly affects the export of nitrogen (N) and phosphorus (P) from oils to surface waters. To study the sorption an mobility of dissolved organic C and P (DOC, DOP) in soil, the pH-dependent sorption of DOM ...

Seasonal changes in optical properties of two contrasting tropical freshwater systems

Journal of Limnology, 2016
We investigated how allochthonous and autochthonous sources of dissolved organic matter (DOM) affected the optical conditions and chemical characteristics of two contrasting tropical freshwater systems (Dom Helvécio-DH and Pampulha reservoir) in a dry ...
