Xu et al. (2025): Microbial decomposition of Sargassum enhances recalcitrant dissolved organic carbon production and sedimentary carbon sequestration

Lili Xu, Bilin Jin, Ligong Zou, Yee Jun Tham, Yufeng Yang and Qing Wang, IN: Journal of Environmental Management, https://doi.org/10.1016/j.jenvman.2025.128430

Seaweeds are fundamental components and primary producers in marine ecosystems, and their growth and decay significantly influence environmental conditions and microbial community structure. However, considerable debate persists regarding whether seaweed decomposition enhances marine carbon sequestration, and the role of microbes in seaweed degradation remains unclear. This study examined the degradation process of Sargassum under controlled laboratory conditions to assess its potential for carbon sequestration.

Lu et al. (2025): From Mechanisms to Markets: A Precision Quantification Framework and Paradigm Shift for Saltmarsh Carbon Sinks

Rui Lu, Qiang Wang, Yanxin Zhao and Yiquan Yuan, IN: ESS Open Archive, https://doi.org/10.22541/essoar.176659808.84665979/v1

Salt marshes play a critical yet poorly quantified role as efficient blue-carbon sinks due to methodological limitations in assessing their complex carbon dynamics. This review synthesizes mechanisms and drivers of saltmarsh carbon sequestration, emphasizing the synergy between biogeomorphic engineering and microbial–geochemical feedbacks that enable long-term carbon stabilization.

Spilmont & Zardi (2025): Intertidal mussel–symbiont associations act as CO₂ sinks during daily emersion

Nicolas Spilmont; Gerardo I. Zardi, IN: Biology Letters, https://doi.org/10.1098/rsbl.2025.0498

Human activities have disrupted the global carbon cycle, reducing carbon dioxide (CO₂) uptake by tidal wetlands and submerged vegetation. This exacerbates climate challenges, including rising temperatures and ocean acidification. Coastal systems such as mangroves and seagrasses serve as key carbon sinks, promising for CO₂ removal (CDR). Growing attention is being given to bivalves, whose calcification and reef-building activities shape coastal carbon dynamics. Most studies reduce bivalve impacts to a balance between individual CO₂ emissions and the carbon stored in their shells and tissues, often overlooking species interactions—such as symbioses—that may modulate carbon fluxes. Here, the authors examined the mussel–symbiont holobiont using Mytilus edulis under emersion in a controlled chamber to quantify CO₂ exchange.

Costa et al. (2025): Indigenous stewardship and co-management in action: a case study on blue carbon from a mangrove ecosystem on the Great Barrier Reef

Micheli D.P. Costa, I. Noyan Yilmaz, Pawel Waryszak, Rory Crofts, Melissa Wartman, Pere Masqué, Brian Singleton, Gavin Singleton, Ashlyn Skeene, Lucy Friend, Peter I. Macreadie, IN: Ocean & Coastal Management, https://doi.org/10.1016/j.ocecoaman.2025.107971

Blue carbon ecosystems play a vital role in climate change mitigation and adaptation through their capacity to sequester and store organic carbon. Queensland, Australia, contains over 500,000 ha of mangroves, much of it under the stewardship of Traditional Custodians. The mangrove forests of the Bidakarra (Barron River) estuary provide a unique opportunity to demonstrate how Indigenous leadership, scientific research, and local industry partnerships can advance both ecological and cultural outcomes. The authors present a co-designed case study from Kukujum (Ellie Point), an area co-managed by Cairns Airport, Yirrganydji Gurabana Aboriginal Corporation, and the Yirrganydji Land and Sea Ranger Program through Dawul Wuru Aboriginal Corporation.

Kuwae et al. (2025): Empirical analysis of project–purchaser dynamics in Japan’s blue carbon dioxide removal credit scheme

Tomohiro Kuwae, Yuka Suzuki and Masanori Furuya, IN: Research Square, https://doi.org/10.21203/rs.3.rs-7525613/v1

Carbon dioxide removal (CDR) and associated credit mechanisms are gaining prominence in carbon neutrality strategies, yet empirical evaluations of their sustainability remain limited. Here, the authors analyzed 61 blue carbon projects and 471 certified transactions under Japan’s J-Blue Credit scheme to examine the characteristics of projects and purchasers and their interrelationships.

Rađenović Veselić et al. (2025): From sink to strategy: Sediments at the nexus of carbon sequestration and climate action

Dunja Rađenović Veselić, Nataša Slijepčević, Slaven Tenodi, Đorđe Pejin, Irina Jevrosimov, Tijana Marjanović Srebro and Dragana Tomašević Pilipović, IN: Earth-Science Reviews, https://doi.org/10.1016/j.earscirev.2025.105310

Sediments are far more than inert deposits beneath our waters, they are dynamic engines of the global carbon cycle. Acting as both long-term carbon vaults and, under disturbed conditions, potent sources of greenhouse gases, sediments hold immense yet underutilized potential in the fight against climate change. This review unpacks the complex mechanisms that govern carbon cycling in sediments, from source inputs and microbial transformations to vertical storage patterns and exchanges with the water column.

Liu et al. (2025): Contrasting soil organic carbon sequestration mechanisms in intertidal and supratidal habitats of coastal wetlands divided by seawalls

Jiayuan Liu, Ning Zhang, Xinyu Miao, Zhen Xu, Tianyu Zhang, Ying Wei, Hailong Wu and Fude Liu, IN: Journal of Cleaner Production, https://doi.org/10.1016/j.jclepro.2025.146636

Soil organic carbon (SOC) sequestration in coastal wetlands is crucial for mitigating global climate change. However, coastal seawall construction alters habitats, potentially affecting the carbon sequestration potential. This study analyzed the content, distribution patterns, and dynamics of SOC and dissolved organic matter (DOM) in two seawall-protected coastal wetlands in the Yellow River Delta, comparing inside (supratidal habitat) and outside (intertidal habitat) habitats.

Fulton et al. (2025): Tracing Blue Carbon Flows Across Diverse Seascapes

Christopher J. Fulton, Diego R. Barneche, Kay Davis, Cal Faubel, Cecilia Pascelli, Julie Vercelloni and Shaun K. Wilson, IN: Global Change Biology, https://doi.org/10.1111/gcb.70420

Plants occupying coastal ecosystems draw in carbon dioxide (CO₂) from the air and water around them during photosynthesis. A fraction of this CO₂ becomes fixed into plant biomass and can eventually contribute to the blue carbon pool—organic carbon (Corg) sequestered in slow-turnover sinks. An important step in protecting and enhancing this natural carbon sequestration pathway is determining the relative contributions of different coastal plants to this blue carbon pool in durable sinks. The authors compiled a global dataset of coastal soil carbon measurements and used a Bayesian hierarchical meta-regression model to explore the relative contribution of local (autochthonous) versus external (allochthonous) sources of Corg in the soils beneath tidal saltmarsh, mangrove, and seagrass wetlands.

Huang et al. (2025): Mangrove restoration enhances blue carbon sequestration and its stability in a subtropical tidal wetland

Xingyun Huang, Wensui Li, Guoming Qin, Fangyuan Guan, Yongxing Cui, Jingwei Shi, Zhe Lu, Lulu Zhang, Jingfan Zhang, Jinge Zhou, Ruyi Ding, Hua He, Evans Asenso, Hui Li, Faming Wang, IN: Functional Ecology, https://doi.org/10.1111/1365-2435.70121

Mangrove forests are among the most productive blue carbon (C) ecosystems. While mangrove restoration is recognized for its potential to increase coastal blue C storage, its effects on soil organic C (SOC) stability and sources remain poorly understood.
Here, the authors examined the effects of mangrove restoration on SOC fractions and explored the relative contributions of plant versus microorganisms to these fractions. Specifically, they assessed the contents of particulate organic carbon (POC), coarse mineral-associated organic carbon (cMAOC), fine mineral-associated organic carbon (fMAOC) and two biomarkers (lignin phenol and amino sugar) across different restored vegetation zones in a typical mature mangrove wetland.
