Organic carbon flux and particulate organic matter composition in Arctic valley glaciers: examples from the Bayelva River and adjacent Kongsfjorden

, 2016
. In the face of ongoing global warming and glacier retreat, the composition and flux of organic matter in glacier–fjord systems are key variables for updating the carbon cycle and budget, whereas the role of Arctic valley glaciers seems unimportant when

Tea cultivation: facilitating soil organic carbon accumulation and altering soil bacterial community—Leishan County, Guizhou Province, Southwest China [PDF]

PeerJ
Background Camellia sinensis is an important cash crop in southwestern China, with soil organic carbon playing a vital role in soil fertility, and microorganisms contributing significantly to nutrient cycling, thus both of them influencing tea tree ...

Massive concentrations of old dissolved organic carbon from Yedoma thaw in lakes in Siberia

Communications Earth & Environment
Understanding the impacts of permafrost thawing on the carbon cycle requires a closer look at the proportion of dissolved and particulate organic carbon released upon thaw, and the magnitude of its conversion into greenhouse gases, which remain ...

Impact of N fertilization on C balance and soil quality in maize-dhaincha cropping sequence [PDF]

Journal of Agricultural Sciences (Belgrade), 2015
Excess N fertilization to achieve high crop yield is a grand old practice in developing countries. However, inorganic nutrient sources considerably replenish soil organic C (SOC).

Validation and Intercomparison of Ocean Color Algorithms for Estimating Particulate Organic Carbon in the Oceans

Frontiers in Marine Science, 2017
Particulate Organic Carbon (POC) plays a vital role in the ocean carbon cycle. Though relatively small compared with other carbon pools, the POC pool is responsible for large fluxes and is linked to many important ocean biogeochemical processes.

The isotopic composition of particulate organic carbon in mountain rivers of Taiwan [PDF]

Geochimica et Cosmochimica Acta, 2010
Small rivers draining mountain islands are important in the transfer of terrestrial particulate organic carbon (POC) to the oceans. This input has implications for the geochemical stratigraphic record. We have investigated the stable isotopic composition of POC (δ13Corg) in rivers draining the mountains of Taiwan. In 15 rivers, the suspended load has a

Diurnal and seasonal variation of particle and dissolved organic matter release by the coral Acropora tenuis [PDF]

PeerJ, 2018
Release rates of particulate organic carbon and nitrogen (POC and PON) and dissolved organic carbon (DOC) from the scleractinian coral Acropora tenuis were measured during the day and night in summer and winter seasons. Physiological parameters including

Arbuscular mycorrhizal fungi communities and glomalin mediate particulate and mineral-associated organic carbon formation in grassland patches

Communications Earth & Environment
Arbuscular mycorrhizal fungi stimulate particulate and mineral-associated organic carbon formation and stabilization through hyphae residue, glomalin-related soil proteins gluing, and mycelium entangling.

The impact of NaOH, CaO, and [Ca²⁺] + [HCO₃⁻] additions on PIC and POC formation in Los Angeles Harbor Waters [PDF]

Biogeosciences
Negative CO2 emission technologies such as ocean alkalinity enhancement, in tandem with emissions reduction are necessary to keep the climate system below a critical tipping point.
