To better understand the sources and recycling of labile organic matter in coastal water, we studied the carbon isotope signature of particulate organic carbon (POC) and particulate amino acids, a major group of labile organic compounds, on the shelf of ...

New organic matter degradation proxies: Valid in lake systems? [PDF]
We determined concentrations and diagenetic state of organic matter in two cores from Lake Zug, Switzerland. To obtain a general picture of organic matter decay in the lake, we measured bulk parameters such as total organic carbon, total nitrogen, and ...

Carbon cycling and POC turnover in the mesopelagic zone of the ocean: Insights from a simple model [PDF]
Carbon budgets of the mesopelagic zone are poorly constrained, highlighting our lack of understanding of the biota that inhabit this environment and their role in the cycling and sequestering of carbon in the deep ocean.

Factors influencing the stable carbon isotopic composition of suspended and sinking organic matter in the coastal Antarctic sea ice environment [PDF]
A high resolution time-series analysis of stable carbon isotopic signatures in particulate organic carbon (δ13CPOC) and associated biogeochemical parameters in sea ice and surface waters provides an insight into the factors affecting δ13CPOC in the ...

Biocatalytic quantification of α‐glucan in marine particulate organic matter
Marine algae drive the marine carbon cycle, converting carbon dioxide into organic material. A major component of this produced biomass is a variety of glycans. Marine α‐glucans include a range of storage glycans from red and green algae, bacteria, fungi,

Zooplankton response to organic carbon level in lakes of differing trophic states
Water eutrophication is associated with an increase in the organic carbon content (both particulate and dissolved forms), which may affect the functioning of the zooplankton community.

Particulate organic carbon: Sampling variability [PDF]
Replicate sampling for particulate organic carbon (POC) in the open ocean indicates that at any given position and depth the POC distribution consists of a homogeneous background concentration on which are superimposed occasional small patches containing two to five times as much organic carbon as is present in the background. The 95% confidence limits

Efecto de diferentes tipos de uso de la tierra en las fracciones del carbono orgánico del suelo
Objectives: To evaluate the effect of different types of land use on the organic carbon fractions of a chromic vertisol soil. Materials and Methods: The research was developed in a permanent observation point, located in Holguin province. Soil samples
