Burial of Terrestrial Organic Matter in Marine Sediments

Oftentimes this organic matter input term is taken to be deposition at the sediment surface, i.e., the rain rate to the sediments. However in the discussions ...

Organic Carbon (OC) and Organic Matter (OM) in Sediments ...

Sediment OM content consists of 5 classes, namely: >35% is considered very high organic matter content; 17% - 35% is high organic matter content; 7% - 17% is ...

Historical changes in organic matter input to the muddy sediments ...

The burial of sedimentary organic matter (SOM) in the large river-influenced estuarine-coastal regions is affected by hydrodynamic sorting, diagenesis and ...

Microbial Organic Matter Degradation Potential in Baltic Sea ...

Globally, marine sediments are a vast repository of organic matter, which is degraded through various microbial pathways, including polymer hydrolysis and ...

Oceanographic controls on the accumulation of organic matter in ...

The concentration of organic matter in marine deposits depends on the relative rates of accumulation of the various sedimentary components and the ease with ...

Characterization of natural organic matter in low-carbon sediments

Organic carbon (OC) concentrations in subsurface sediments are typically 10 to 200 times lower than in surface soils, posing a distinct challenge for ...

Characteristics of Sedimentary Organic Matter in Tidal Estuaries

In this paper, we took the Minjiang River Estuary (MRE) as a typical system in which there is strong influence of the tide.

Degradation and Preservation of Organic Matter in Marine Sediments ... Organic matter that is deposited in aquatic sediments is subject to an ...

Organic matter mineralization in intertidal sediments along an ...

In order to study the rate of sedimentary organic matter decomposition as a function of organic matter input and decomposition pathways, 8 ...

Preservation of Organic Matter in Marine Sediments

The burial of organic matter (OM) in marine sediments represents the major link between “active” surface pools of carbon in the oceans, atmosphere, on land, and ...

Organic Matter in Marine Sediments Off East Coast of India

This corresponds with 1.33% organic matter which is much less than the worldwide average of 2.5% for nearshore sediments (Trask, 1939). The ...

Terrigenous Organic Matter in Sediments of the St. Lawrence ...

Terrigenous Organic Matter in Sediments of the St. Lawrence Estuary and the Saguenay Fjord · Abstract · Résumé · Formats available · Information & Authors.

Early diagenesis of organic matter in marine sediments - NASA ADS
