Microbial Metabolism and Environmental Controls of Acetate Cycling in the Northwest Pacific Ocean

Geophysical Research Letters, Год журнала: 2024, Номер 51(17)

Abstract Microbial acetate metabolism is an important part of marine carbon cycling. We present a comprehensive study to constrain microbial and its regulation in surface seawater the northwest Pacific Ocean. found that oxidation (rate constant k : 0.016–0.506 day −1 ) accounted for 77.6%–99.4% total uptake, suggesting was predominantly used as energy source. Acetate also served significant biomass source, reflected by elevated contribution assimilation bacterial production. turnover largely influenced water mass mixing nutrient conditions. Atmospheric deposition source this process can impact uptake. utilization could account up 25.9% demand, role cycling open ocean.

Composition and Biogeochemical Effects of Carbohydrates in Aerosols in Coastal Environment

Journal of Marine Science and Engineering, Год журнала: 2024, Номер 12(10), С. 1834 - 1834

We adopted a simple and rapid measurement method to analyze the concentrations of monosaccharides (MCHO) polysaccharides (PCHO) in carbohydrates, subset organic carbon found size-fractionated atmospheric particles. Seasonal source-related factors influenced carbohydrate concentrations, with total water-soluble carbohydrates (TCHO) accounting for approximately 23% (WSOC) spring when biological activity was high. observed that mode aerosol transport significantly particle size distribution MCHO exhibiting relatively high fine particles (<1 μm) PCHO showing higher coarse (>1 μm). Moreover, our results revealed contributed 51% 49%, respectively, TCHO concentration. This contribution varied by ±19% depending on season, suggesting importance both PCHO. Additionally, through combined use principal component analysis (PCA) positive matrix factorization (PMF), we determined biomass burning accounts 30% aerosol. Notably, 52% WSOC flux, 78% from this source, indicating substantial influence composition. The average concentration TCHO/WSOC atmosphere 18%, similar marine environment, reflecting relationship between biogeochemical cycles two environments. Finally, fluxes were 1.10 5.28 mg C m−2 yr−1, respectively. also deposition primary productivity winter 15 times greater than summer, had significant impact ecosystems during nutrient-poor seasons. discovered 62% dissolved (DOC) Min River, could be major source region.
