Laminarin is a major molecule in the marine carbon cycle [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 2020
Marine microalgae sequester as much CO 2 into carbohydrates as terrestrial plants. Polymeric carbohydrates (i.e., glycans) provide carbon for heterotrophic organisms and constitute a carbon sink in the global oceans.

New Perspectives on the Marine Carbon Cycle–The Marine Dissolved Organic Matter Reactivity Continuum

Environmental Science & Technology, 2022
This perspective challenges our current understanding of the marine carbon cycle, including an alternative explanation of bulk 14C-DOM measurements. We propose the adoption of the carbon reactivity continuum concept previously established for lakes and sediments for the oceans using kinetic data and term this the marine DOM reactivity continuum.

Revisiting the hydrological basis of the Budyko framework with the principle of hydrologically similar groups [PDF]

Hydrology and Earth System Sciences, 2023
The Budyko framework is a simple and effective tool for estimating the water balance of watersheds. Quantification of the watershed-characteristic-related parameter (Pw) is critical for accurate water balance simulations with the Budyko framework ...

Microbial metabolites in the marine carbon cycle

Nature Microbiology, 2022
One-quarter of photosynthesis-derived carbon on Earth rapidly cycles through a set of short-lived seawater metabolites that are generated from the activities of marine phytoplankton, bacteria, grazers and viruses. Here we discuss the sources of microbial metabolites in the surface ocean, their roles in ecology and biogeochemistry, and approaches that ...

Marine Viruses and Their Role in Marine Ecosystems and Carbon Cycling [PDF]

Annual Review of Marine Science
Marine viral ecology emerged as a distinct discipline approximately 25 years ago. Despite significant progress, direct assessments of viral impacts on carbon flux remain scarce. Here, we integrate recent advances and knowledge gaps in marine viral ecology and a comprehensive conceptual viral-engine framework, highlighting the various ways in which ...

The Impact of Zooplankton Calcifiers on the Marine Carbon Cycle

Global Biogeochemical Cycles, 2023
Abstract Shelled pteropods and planktic foraminifers are calcifying zooplankton that contribute to the biological carbon pump via the sinking of their calcareous shells. However, their importance for regional and global plankton biomass and carbon fluxes is not well understood.

Transfer efficiency of organic carbon in marine sediments

Nature Communications, 2022
The burial of organic carbon in marine sediments regulates Earth’s carbon cycle and climate. Here, authors present ‘transfer efficiencies’ as a new framework for quantifying the sedimentary portion of the marine organic carbon cycle.

Marine biodiversity, ecosystem functioning, and carbon cycles [PDF]

Proceedings of the National Academy of Sciences, 2010
Although recent studies suggest that climate change may substantially accelerate the rate of species loss in the biosphere, only a few studies have focused on the potential consequences of a spatial reorganization of biodiversity with global warming.

Past changes in and present status of the coastal carbon cycle

Cambridge Prisms: Coastal Futures, 2023
Data were obtained from the literature to identify past changes in and the present status of the coastal carbon cycle. They indicate that marine coastal ecosystems driving the coastal carbon cycle cover, on average, 5.8% of the Earth’s surface and ...

Biocatalytic quantification of α‐glucan in marine particulate organic matter

MicrobiologyOpen, 2022
Marine algae drive the marine carbon cycle, converting carbon dioxide into organic material. A major component of this produced biomass is a variety of glycans. Marine α‐glucans include a range of storage glycans from red and green algae, bacteria, fungi,
