Microbial communities and functional diversity in seafood

JSFA reports, EarlyView.
Abstract Functional diversity encompasses ecosystem processes that enhance adaptability to environmental change. This study explores the diversity of microorganisms associated with seafood. In this paper, we present our knowledge of microbial diversity in relation to seafood.

Resilience to Alkalinity Perturbations Reveals Ecosystem Stability under Ocean Alkalinity Enhancement

Ocean-Land-Atmosphere Research
Ocean alkalinity enhancement (OAE) is a leading climate mitigation strategy for atmospheric carbon dioxide removal, with theoretical potential to sequester gigatons of CO2 annually while counteracting ocean acidification.

Sodium sulfite can reliably induce chemical hypoxia without toxic effects in the model sea anemone species, Exaiptasia diaphana

Limnology and Oceanography: Methods, EarlyView.
Abstract Climate change is accelerating the deoxygenation of aquatic ecosystems, so understanding its effects on biological processes is increasingly critical. An emerging method for inducing hypoxia during experimentation utilizes sodium sulfite (SSI) to scavenge oxygen; however, it remains unclear if hypoxia‐inducing concentrations of SSI are toxic ...

Marine Negative Emission Technologies: A Review of Theory and Applications [PDF]

E3S Web of Conferences
Achieving carbon neutrality by 2060 requires coordinated scientific efforts to tackle intensifying climate challenges. To balance environmental conservation with economic growth, emission reductions must be coupled with effective negative emissions ...

Evaluation of methods for the analysis of oxygen and carbon dioxide in water, sediment, litter, and soil

Limnology and Oceanography: Methods, EarlyView.
Abstract Choosing an appropriate analyzer to measure concentrations of oxygen (O2) and carbon dioxide (CO2) during biogeochemical cycling studies can be difficult, considering the range of options available. While several studies examine the abilities of specific analyzers, comparison of multiple analyzers and environmental sample types is lacking.

Intercomparison of carbon‐13 and carbon‐14 tracer approaches for estimating marine calcification and net primary production

Limnology and Oceanography: Methods, EarlyView.
Abstract Accurate measurements of phytoplankton net primary production (NPP) and calcification are essential for quantifying marine carbon cycling, yet in situ calcification rates remain poorly constrained. We compared 13C‐ and 14C‐based tracer methods for NPP in laboratory cultures of the diatom Chaetoceros tenuissimus and the coccolithophore ...

Contribution of ultrafine particles to alkalinity in a limestone‐treated waterbody

Limnology and Oceanography: Methods, EarlyView.
Abstract While it is well recognized that suspended particles can bias titration‐based total alkalinity (TA), whether addition of minerals for alkalinity enhancement introduces systematic TA artifacts remains poorly quantified. To address this gap, we quantified the contribution of ultrafine particles (< 0.2 μm) to TA titration introduced by limestone (

The Prospect of Ocean Negative Carbon Emission Technologies on the Ecological Improvement

Haiyang Kaifa yu guanli
Carbon dioxide anthropogenic emission have led to global warming, triggering a series of negative environmental effects such as extreme weather, rising sea level, seawater acidification and so on.

How well do global ocean approaches constrain local fCO2?

Environmental Research Letters
The ocean absorbs 29% of humanity’s annual anthropogenic carbon dioxide (CO $_2$ ) emissions, and the future of climate change is strongly dependent on how this sink evolves.

Is mCDR pollution? Rethinking pollution for the governance of marine carbon dioxide removal

Earth System Governance
Marine carbon dioxide removal (mCDR) is increasingly explored as component within the global response to climate change, yet its governance remains fragmented and conceptually unsettled.
