Organic carbon decay mediated by a mesopelagic microbial …
2025年1月17日 · Here we followed the decay of 14 C-labeled dead particulate organic carbon (POC) and dissolved organic carbon (DOC) from three different phytoplankton species, and two incubations of live diatoms, in mesopelagic water over 3 months. Commonly used first-order kinetics failed to adequately describe the decay of organic material as rate constants ...
MOdern River archivEs of Particulate Organic Carbon: MOREPOC
2022年10月28日 · Here, we present a new, open-access, georeferenced, and global database called MOdern River archivEs of Particulate Organic Carbon (MOREPOC) version 1.1, featuring data on POC in suspended particulate matter (SPM) collected at …
Frontiers | Particulate Organic Carbon Deconstructed: Molecular …
Conceptual overview of marine particulate organic carbon (POC) in the ocean. POC includes components of living cells as well as dead material (detritus), and originates from both allochthonous and autochthonous sources. The POC pool can also exchange material with the dissolved OC (DOC) pool through aggregation and disaggregation of particles.

2022年10月1日 · The river-delivered POC can be described as a mixture of biospheric (radiocarbon-enriched POC) and petrogenic components (radiocarbon-dead POC).
Effects of migrating mesopelagic fishes on the biological carbon …
2023年8月24日 · Diffusive POC flux is the diffusive flux of suspended detritus (dead POC) and of microbial organisms (living POC). Active flux is the migrant carbon transport calculated according to...
Dam-triggered organic carbon sequestration makes the …
Worldwide dam building in large river basins has substantially altered the carbon cycle by trapping much of the riverine transported particulate organic carbon (POC) in terrestrial reservoirs.
