The pressing need to mitigate the effects of climate change is driving development novel approaches for carbon dioxide removal (CDR) from atmosphere, with ocean playing a central role in portfolio solutions. expansion seaweed farming increasingly considered as one potential CDR avenues among government and private sectors. Yet, comprehensive assessments examining whether can lead tangible mitigation remain limited. Here we examine results over 100 publications synthesize evidence regarding capacity farms review different interventions through which an may contribute mitigation. We find that presently, majority fixed by seaweeds stored short-term reservoirs (e.g., products) only minority ends up long-term are likely fit within existing international accounting frameworks marine sediments). Additionally, tiny global area cultivated date (0.06 % estimated wild extent) limits present mid-term future. A first-order estimate using best available data suggests that, at present, even low emissions scenario, any provided globally be offset their (median balance net emitter: -0.11 Tg C yr

ABSTRACT Blue carbon habitats, which exhibit high rates of natural sequestration, typically refer to salt marshes, seagrass meadows, and mangrove forests. Recent studies, however, have argued for the inclusion seaweed‐dominated like kelp forests, into blue frameworks. Farmed seaweed may also function as a habitat, with large‐scale aquaculture suggested climate change mitigation strategy, but evidence base remains limited. Here, existing knowledge on mechanisms influencing uptake, release, transport, storage from farms was synthesised, literature review conducted quantify associated sequestration. We identified strong geographical methodological biases in literature, majority studies Asia focusing primary production proxy sequestration potential. Estimates release were highly variable across locations, species, approaches, scarcity research dissolved organic carbon, sedimentary net ecosystem productivity identified. Although European farming industry is its infancy, it predicted expand meet increasing demand biomass. This incentivised by perceived service benefits such enhanced However, multiple factors including environmental concerns, lack quantitative evidence, operational challenges, regulatory complexities hinder expansion.

Seaweed plays a critical role in marine carbon sequestration due to its high release rate of organic matter. However, the impacts Porphyra cultivation on concentration and composition dissolved, particulate sedimentary matter (DOM, POM SOM) coastal zones remain unclear. Herein, we investigated optical properties DOM, SOM along transect from subtropical Chi River adjacent zone Dayu Bay (southeast China) during late stage. The results revealed that all types were predominantly characterized by highly autochthonous sources, contrasting sharply with allochthonous, terrestrial sources observed at freshwater sites. estuarine mixing model principal component analysis further indicated dynamics are primarily controlled cultivation, relatively limited contributions riverine inputs, sediment porewater sources. leads significant additions protein-like components water sediment. Microbial degradation incubations DOM demonstrated promotes situ production humic-like (peak M) water. exhibited higher microbial transformation efficiency into refractory than POM, suggesting more substantial sequestration. Our findings underscore potential enhance ecosystems.

Following a tendency of many economies to shift towards carbon neutrality, there came the necessity for certain regions be assessed in terms their greenhouse gas emissions from ocean. A polygon was created Sakhalin Oblast order evaluate balance this marine ecosystem sub-arctic region, with possibility deploying farms additional CO2 absorption. To obtain such an assessment, it seems crucial analyze hydrochemical parameters that reflect situation environment Aniva Bay as basis polygon. The article presents results analysis waters and spatial seasonal variability. This research based on available published sources measurement databases period 1948–1994. Additionally, review uses data 2001–2013 weather station 2008–2023 2008–2023. Some tendencies were discovered temporal distributions oxygen, pH, biogenic matter (inorganic phosphorus, inorganic nitrogen, silicon). In surface layers, mean oxygen year maximum (9.1 mg/L) is registered beginning photosynthesis, i.e., immediately after ice melting April. highest pH values 8.26 are euphotic layer May. lowest August (7.96) near-bottom layer. annual P-PO4 (>18 µg/L) melting, minimum (7.17 at end July. Si-SiO3 concentrations have two maximums: June October. N-NO2 concentration >2 µg/L mid-July 50 m depth >3.5 mid-September. patterns shown maps.
