Dissolved Organic Matter in the Ocean: A Controversy Stimulates New Insights [PDF]

Oceanography, 2009
Containing as much carbon as the atmosphere, marine dissolved organic matter is one of Earth’s major carbon reservoirs. With invigoration of scientific inquiries into the global carbon cycle, our ignorance of its role in ocean biogeochemistry became ...

Molecular Insights into the Transformation of Dissolved Organic Matter in Landfill Leachate Concentrate during Biodegradation and Coagulation Processes Using ESI FT-ICR MS.

Environmental Science and Technology, 2017
Landfill leachate concentrate is a type of refractory organic wastewater with high environmental risk. Identification of refractory components and insights into the molecular transformations of the organics are essential for the development of efficient ...

Organic matter governs N and P balance in Danube Delta lakes [PDF]

, 2018
The transformation of dissolved inorganic nitrogen (DIN) and soluble reactive phosphorous (SRP), and the release of dissolved organic and particulate N and P, were analyzed in two lake complexes (Uzlina-Isac and Puiu-Rosu-Rosulet) of the Danube Delta ...

Microbial Interactions With Dissolved Organic Matter Drive Carbon Dynamics and Community Succession

Frontiers in Microbiology, 2018
Knowledge of dynamic interactions between natural organic matter (NOM) and microbial communities is critical not only to delineate the routes of NOM degradation/transformation and carbon (C) fluxes, but also to understand microbial community evolution ...

Contrasting seasonality in optical-biogeochemical properties of the Baltic Sea [PDF]

, 2017
Optical-biogeochemical relationships of particulate and dissolved organic matter are presented in support of remote sensing of the Baltic Sea pelagic. This system exhibits strong seasonality in phytoplankton community composition and wide gradients of ...

Addition of Macromolecular Marine DOM Cycling to the Marine Biogeochemistry Library (MARBL)

Journal of Advances in Modeling Earth Systems
The differential cycling of marine macromolecules, such as dissolved carbohydrates, proteins, and lipids play a fundamental role in marine microbial metabolisms, ultimately regulating the ocean's capacity to sequester carbon downwards via the biological ...

Ecosystem respiration: Drivers of daily variability and background respiration in lakes around the globe [PDF]

, 2013
We assembled data from a global network of automated lake observatories to test hypotheses regarding the drivers of ecosystem metabolism. We estimated daily rates of respiration and gross primary production (GPP) for up to a full year in each lake, via ...

Ocean liming effects on dissolved organic matter dynamics [PDF]

Biogeosciences
Ocean liming has gained attention as a potential solution to mitigate climate change by actively removing carbon dioxide (CO2) from the atmosphere. The addition of hydrated lime to oceanic surface water leads to an increase in alkalinity, which in turn ...
