Constraining growth rates and the ratio of living to nonliving particulate carbon using beam attenuation and adenosine‐5′‐triphosphate at Station ALOHA

open access: yesLimnology and Oceanography Letters, Volume 6, Issue 5, Page 243-252, October 2021., 2021
Abstract Carbon is not only the foundation of all life on our planet, but also an element that persists in detrital material long after living organisms die. Quantifying the relative amount of living and nonliving carbon in suspended particles in the ocean is challenging and rarely done; yet it is key to understanding the fate of organic matter and ...

The Effect of Crop Growth Stage on the Formation And Ability of Carbon Occlusion within Phytoliths in Rice Varieties [PDF]

open access: yes, 2023
Carbon occlusion refers to the process by which carbon dioxide is incorporated into the silica structure of phytoliths during their formation. Microscopic silica formations called phytoliths develop inside plant cells.

Specific PhytOC fractions in rice straw and consequent implications for potential of phytolith carbon sequestration in global paddy fields

open access: yesScience of The Total Environment, 2023
Phytoliths are silica biomineralization products within plants and have been considered as a promising material to sequester carbon (C). However, there is considerable uncertainty and controversy regarding the C content in phytoliths due to the lack of detailed information on variation of C under different extraction procedures.

Relative Impact of Sea Ice and Temperature Changes on Arctic Marine Production

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 125, Issue 7, July 2020., 2020
Abstract We use a modern Earth system model to approximate the relative importance of ice versus temperature on Arctic marine ecosystem dynamics. We show that while the model adequately simulates ice volume, water temperature, air‐sea CO2 flux, and annual primary production in the Arctic, itunderestimates upper water column nitrate across the region ...

Modeled Chl:C ratio and derived estimates of phytoplankton carbon biomass and its contribution to total particulate organic carbon in the global surface ocean [PDF]

open access: yes, 2016
Chlorophyll (Chl) is a distinctive component of autotrophic organisms, often used as an indicator of phytoplankton biomass in the ocean. However, assessment of phytoplankton biomass from Chl relies on the accurate estimation of the Chl:carbon(C) ratio ...

Organic facies variation in the late Kimmeridgian of the Boulonnais area (northernmost France) [PDF]

open access: yes, 2001
Recent studies of the upper Kimmeridgian of the Boulonnais area (northernmost France) have provided a sequence-stratigraphical framework that is here used to help interpret variations in sedimentary organic matter (OM) content and composition in response

New fluorogenic probes for neutral and alkaline ceramidases [PDF]

open access: yes, 2021
New fluorogenic ceramidase substrates derived from the N-acyl modification of our previously reported probes (RBM14) are reported. While none of the new probes were superior to the known RBM14C12 as acid ceramidase substrates, the corresponding nervonic ...
