Total Observed Organic Carbon (TOOC): A synthesis of North American observations [PDF]

, 2007
Measurements of organic carbon compounds in both the gas and particle phases measured upwind, over and downwind of North America are synthesized to examine the total observed organic carbon (TOOC) over this region.

High-resolution Quaternary record of marine organic carbon content in the hemipelagic sediments of the Japan Sea from bromine counts measured by XRF core scanner

Progress in Earth and Planetary Science, 2019
The marine organic carbon content in sediments is a useful tool for reconstructing past productivity in the ocean. Bromine has been proposed as a useful proxy for marine organic carbon, since bromine is more concentrated in marine organic matter compared

Zooplankton response to organic carbon level in lakes of differing trophic states

Knowledge and Management of Aquatic Ecosystems, 2014
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.

Evolution of Atmospheric Total Organic Carbon from Petrochemical Mixtures [PDF]

Environmental Science & Technology, 2021
Reactive organic compounds play a central role in the formation of ozone and secondary organic aerosols. The ability to accurately predict their fate, in part, relies upon quantitative knowledge of the chemical and physical parameters associated with the total organic carbon (TOC), which includes both precursors and oxidation products that evolve in ...

Effects of land use on Soil Organic Carbon fractions in soils of Njala Landscape in Sierra Leone [PDF]

, 2016
Soil organic carbon fractions reflect the difference in soil organic carbon from one land use to another, and it can be regarded as an indication of the degree of soil organic carbon deterioration or improvement.

Evaluation of Land Fertility Status in Tirtomoyo District, Wonogiri Regency, Indonesia

Sains Tanah: Journal of Soil Science and Agroclimatology, 2017
Evaluation of soil fertility status on agricultural is to know the fertility of soil chemically through soil analysis or soil test. This is done to obtain estimates data of land characteristics based on parameters observed and tested for various ...

Geogenic organic carbon in terrestrial sediments and its contribution to total soil carbon [PDF]

SOIL, 2021
Geogenic organic carbon (GOC) from sedimentary rocks is an overlooked fraction in soils that has not yet been quantified but influences the composition, age, and stability of total organic carbon (OC) in soils.

A model of nitrous oxide evolution from soil driven by rainfall events: 1. Model structure and sensitivity [PDF]

, 1992
This paper describes a rain-event driven, process-oriented simulation model, DNDC, for the evolution of nitrous oxide (N2O), carbon dioxide (CO2), and dinitrogen (N2) from agricultural soils.
