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

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.

Oceanographic Profiling Observations from the MOCE-3 Cruise: 27 October to 15 November 1994 [PDF]

open access: yes, 1995
This report contains results from the third cruise of the Marine Optical Characterization Experiment (Fig. 1). A variety of spectroradiometric observations of the upper water column and atmosphere were made by investigators from the University of Miami ...

Estimating the Colored Dissolved Organic Matter in the Negro River, Amazon Basin, with In Situ Remote Sensing Data

open access: yesRemote Sensing
Dissolved organic matter (DOM) is a crucial component of continental aquatic ecosystems. It plays a vital role in the carbon cycle by serving as a significant source and reservoir of carbon in water.

Modeling dissolved organic matter mobilization and immobilization in the root zone: Effect of soil treatment on denitrification and N leaching [PDF]

open access: yes, 2005
This report summarizes the technical description of a code/model concept simulating mobilization and immobilization of dissolved organic matter (DOM) in the Daisy model.

The unique biogeochemical role of carbonate-associated organic matter in a subtropical seagrass meadow

open access: yesCommunications Earth & Environment
The particulate organic matter buried in carbonate-rich seagrass ecosystems is an important blue carbon reservoir. While carbonate sediments are affected by alkalinity produced or consumed in seagrass-mediated biogeochemical processes, little is known ...

2004 Great Bay Organic Nitrogen (PON & DON) and Light Extinction (PAR) Monitoring Program [PDF]

open access: yes, 2005
Nitrogen is most often considered to be the limiting nutrient for plant growth in marine waters. As a result, knowledge of nitrogen loading and ambient water-column concentrations are considered to be critical to understanding the response of aquatic ...

Temperature and nutrient stoichiometry interactively modulate organic matter cycling in a pelagic algal-bacterial community [PDF]

open access: yes, 2011
A microcosm experiment was conducted to investigate the interactive effects of rising sea-surface temperature and altered nutrient stoichiometry on the biogeochemical cycling of organic matter in a pelagic algal–bacterial assemblage.

Halogenated Organic Compounds: A Massive Halogen Reservoir and an Intriguing Component of the Marine Dissolved Organic Matter Pool

open access: yesGeophysical Research Letters
Biogeochemical reactions produce volatile halocarbons and semi‐ to nonvolatile dissolved organic halogens (DOX) in marine systems. The former has a large influence on atmospheric chemistry, but little is known about DOX.
