TLDR
The photoreactivity of chromophoric dissolved organic matter (CDOM) transported to Arctic shelf environments by rivers has only recently been studied and its quantitative role in Arctic shelf biogeochemistry has received little attention as discussed by the authors.About:

Journal ArticleDOI
Fluorescence tracking of dissolved and particulate organic matter quality in a river-dominated estuary.
TL;DR: Modeling base-extracted particulate and dissolved organic matter quality in the Neuse River Estuary before and after passage of Hurricane Irene indicated that advection of pore water DOM from surface sediments into overlying waters could increase the autochthonous quality of DOM in shallow microtidal estuaries.
Journal ArticleDOI
The importance of charge-transfer interactions in determining chromophoric dissolved organic matter (CDOM) optical and photochemical properties
TL;DR: This review summarizes current understanding of the processes underlying CDOM photophysics and photochemistry as well as their physical basis.
Journal ArticleDOI
Detecting the signature of permafrost thaw in Arctic rivers
Robert G. M. Spencer,Paul J. Mann,Thorsten Dittmar,Timothy I. Eglinton,Cameron McIntyre,R. Max Holmes,Nikita Zimov,Aron Stubbins +7 more
TL;DR: In this article, the authors highlight that ancient (>20,000 years B.P.) permafrost DOC is rapidly utilized by microbes and that the decay rates for DOC in a major arctic river (Kolyma: 0.19

Controls on the composition and lability of dissolved organic matter in Siberia's Kolyma River basin
Paul J. Mann,Anna Davydova,Nikita Zimov,Robert G. M. Spencer,Sergey Davydov,Ekaterina Bulygina,Sergei Zimov,Robert M. Holmes +7 more
TL;DR: In this paper, the authors examined DOC concentration and the composition of dissolved organic matter (DOM) across the hydrograph in Siberia's Kolyma River, with a particular focus on the spring freshet period when the majority of the annual DOC load is exported.
Journal ArticleDOI
Nutrients in estuaries--an overview and the potential impacts of climate change.
TL;DR: A more holistic approach is needed to effectively understand, predict and manage the impact of macronutrients on estuaries, and development of high frequency in situ nutrient analysis systems will provide data to improve predictive models that need to incorporate a wider variety of key factors.

Carbon pools and flux of global forest ecosystems.
Robert K. Dixon,Allen M. Solomon,Sandra Brown,Richard A. Houghton,M. C. Trexier,J. Wisniewski +5 more
TL;DR: Slowing deforestation, combined with an increase in forestation and other management measures to improve forest ecosystem productivity, could conserve or sequester significant quantities of carbon.
Book
Biogeochemistry of marine dissolved organic matter
TL;DR: The second edition of the Biogeochemistry of Marine Dissolved Organic Matter (Second Edition) as discussed by the authors provides a comprehensive overview of the major advances in this area and includes new chapters covering the role of DOM in ancient ocean carbon cycles, the long term stability of marine DOM, the biophysical dynamics of DOM, fluvial DOM qualities and fate, and the Mediterranean Sea.
Journal ArticleDOI
The biogeochemistry of the river and shelf ecosystem of the Arctic Ocean: a review
Thorsten Dittmar,Gerhard Kattner +1 more
TL;DR: In this article, the authors reviewed the current knowledge about the biogeochemistry of the Arctic river and shelf ecosystem and found that dissolved organic carbon (DOC) concentrations in the Arctic rivers are among the highest reported in worlds rivers.

Photobleaching of chromophoric dissolved organic matter in natural waters: kinetics and modeling
TL;DR: In this paper, the effects of monochromatic and polychromatic UV and VIS radiation on the optical properties (absorption and fluorescence) of chromophoric dissolved organic matter (CDOM) were examined for a Suwannee River fulvic acid (SRFA) standard and for water from the Delaware and Chesapeake Bays.

Trajectory shifts in the Arctic and subarctic freshwater cycle.
Bruce J. Peterson,James W. McClelland,Ruth G. Curry,Robert M. Holmes,John Walsh,Knut Aagaard +5 more
TL;DR: The changes in freshwater inputs and ocean storage occurred in conjunction with the amplifying North Atlantic Oscillation and rising air temperatures, and fresh water may now be accumulating in the Arctic Ocean and will likely be exported southward if and when the North AtlanticOscillation enters into a new high phase.
