Seagrass meadows are considered important natural carbon sinks due to their capacity store organic (Corg) in sediments. However, the spatial heterogeneity of storage seagrass sediments needs be better understood improve accuracy Blue Carbon assessments, particularly when strong gradients present. We performed an intensive coring study within a sub-tropical estuary assess variability sedimentary Corg associated with seagrasses, and identify key factors promoting this variability. found...
Abstract. Biotic and abiotic factors influence the accumulation of organic carbon (Corg) in seagrass ecosystems. We surveyed Posidonia sinuosa meadows growing different water depths to assess variability sources, stocks rates Corg. show that over last 500 years, P. closer upper limit distribution (at 2–4 m depth) accumulated 3- 4-fold higher Corg (averaging 6.3 kg m−2) at (12.8 g m−2 yr−1) compared deep limits 6–8 depth; 1.8 3.6 yr−1). In shallower meadows, were mostly derived from detritus...
Abstract Global‐scale ocean acidification has spurred interest in the capacity of seagrass ecosystems to increase seawater pH within crucial shoreline habitats through photosynthetic activity. However, dynamic variability coastal carbonate system impeded generalization into whether aerobic metabolism ameliorates low on physiologically and ecologically relevant timescales. Here we present results most extensive study date modulation by seagrasses, spanning seven meadows ( Zostera marina )...
Abstract Sinking vast amounts of seaweed in the deep ocean is currently being proposed as a promising carbon dioxide removal strategy well natural-based solution to mitigate climate change. Still, marketable offsets through large-scale sinking lack documentation and could involve unintended environmental social consequences. Managing risks requires number urgent actions.
Abstract Marine kelp forests cover 1/3 of our world's coastlines, are heralded as a nature-based solution to address socio-environmental issues, connect hundreds millions people with the ocean, and support rich web biodiversity throughout oceans. But they increasingly threatened some areas reporting over 90% declines in forest living memory. Despite their importance threats face, entirely absent from international conservation dialogue. No laws, policies, or targets focus on very few...
The seagrass Posidonia oceanica is the main habitat-forming species of coastal Mediterranean, providing millennial-scale ecosystem services including habitat provisioning, biodiversity maintenance, food security, protection, and carbon sequestration. Meadows this endemic represent largest storage among seagrasses around world, largely contributing to global blue stocks. Yet, slow growth temperate extreme projected temperature sea-level rise due climate change increase risk reduction loss...

Abstract. Salt marshes and seagrass meadows can sequester store high quantities of organic carbon (OC) in their sediments relative to other marine terrestrial habitats. Assessing stocks, sources, the transfer between habitats within coastal seascapes are each integral identifying role blue cycling. Here, we quantified exchanges meadows, salt marshes, unvegetated six bays along California coast. In top 20 cm sediment, contained approximately twice as much OC did, 4.92 ± 0.36 kg m−2 compared...
Although seaweeds rank among the most productive vegetated habitats globally, their inclusion within Blue Carbon frameworks is at its onset, partially because they usually grow in rocky substrates and organic carbon (C
Greenhouse gas emissions from land-use change, fossil fuel, agriculture, transportation, and electricity sectors expose marine ecosystems to overlapping environmental stressors. Existing climate vulnerability assessment methods analyze the frequency of extreme conditions but often minimally consider how data gaps hinder assessments. Here, we show an approach that assesses uncertainty introduced by monitoring gaps, using a case study ocean acidification deoxygenation in coastal California. We...
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,...
Understanding the carbon sequestration potential of blue ecosystems is a crucial component for developing nature-based solutions to combat climate change. Alkalinity generation an often-overlooked mechanism, especially in seagrass meadows. Here, we quantified alkalinity (TA) and dissolved inorganic (DIC) fluxes at temperate meadows Sweden, using 24-hour in-situ chamber incubations during late part productive season early September. Observed net TA water column 22 ± 10 mmol m-2 d-1...
Abstract Coastal wetlands, including seagrass meadows, emergent marshes, mangroves, and temperate tidal swamps, can efficiently sequester store large quantities of sediment organic carbon (SOC). However, SOC stocks may vary by ecosystem type along environmental or climate gradients at different scales. Quantifying such variability is needed to improve blue accounting, conservation effectiveness, restoration planning. We analyzed in 1,284 cores >6,500 km the Pacific coast North America...
Patchy global data on belowground litter decomposition dynamics limit our capacity to discern the drivers of carbon preservation and storage across inland coastal wetlands. We performed a global, multiyear study in over 180 wetlands 28 countries 8 macroclimates using standardized as measures "recalcitrant" (rooibos tea) "labile" (green organic matter (OM) decomposition. Freshwater tidal marshes had highest tea mass remaining, indicating greater potential for these ecosystems. Recalcitrant OM...
Abstract The hypothesis that seaweed farming contributes to carbon burial below the farms was tested by quantifying rates in 20 distributed globally, ranging from 2 300 years operation and 1 ha 15,000 size. This involved combining analyses of organic density with sediment accumulation rate sediments relative reference beyond farm and/or prior operation. One every four sampled set over environments export, rather than retain materials. For were placed depositional environments, where could be...
A double-platform protocol was implemented in the Bay of Biscay and English Channel during SCANS-III survey (2016). Two observation platforms using different protocols were operating on board a single aircraft: reference platform (Scans), targeting cetaceans, 'Megafauna' platform, recording all marine fauna visible at sea surface (jellyfish to seabirds). We tested for potential bias small cetacean detection density estimation when fauna. At temporal scale (30 s, roughly 1.5 km), our results...
