The Blue Carbon of Southern South West Atlantic salt marshes and their biotic and abiotic drivers
<p>Organic carbon stocks, salt marsh plant biomass, crab burrow abundances and diameters. This data was generated by sampling at 11 salt marsh sites along 3000 km of coastal line in southern SW Atlantic coast in South America. Organic carbon stocks and burial rates extarcted from other publications and used to update global estimates are also included with their respective references. Values of biotic and abiotic drivers included in the Structural Equation Model (SEM) to evaluate their roles in belowground organic carbon stocks.</p>
Organic and inorganic data for soil cores from Brazil and Florida Bay seagrasses to support Howard et al 2018, CO2 released by carbonate sediment production in some coastal areas may offset the benefits of seagrass “Blue Carbon” storage, Limnology and Oceanography, DOI: 10.1002/lno.10621
Using piston corers, soils from Florida Bay and Brazilian seagrass meadows were collected to complete organic and inorganic carbon inventories for the top 1 m of soil. Instrumental analyses and loss on ignition at 500C were used to measure C content of downcore slices.
Predicted Surficial Blue Carbon Maps for Blackbird Creek and St. Jones River Tidal Salt Marshes using 2014-2023 Landsat-8 OLI records
These data tables reflect the predictions of a gradient boosted trees model for predicting soil organic matter (SOM) in the surficial layer of tidal marsh soils. The model was trained on soil core data related to its corresponding spectral characteristics from decadal Landsat-8 Operational Land Imager data (see associated publication Warner et al. "Leveraging a decade of Landsat-8 spectral records for mapping blue carbon storage in tidal salt marshes"). This is a modeled data product designed to illustrate spatial patterns of organic matter storage as predicted by satellite data.
Century-scale resilience of stored seagrass blue carbon in coastal Virginia
Blue carbon sequestration in coastal ecosystems is only relevant to climate change mitigation and carbon offset crediting if the carbon is taken out of circulation for at least a century. Here, we report data from sediment cores, up to 2.2 m deep, collected below modern Zostera marina seagrass meadows in Mid-Atlantic lagoons in Virginia, USA. Integrated data on Pb-210 and C-14 dating, sediment organic matter and carbon content, and stable isotopic and DNA analysis of sediment samples revealed that buried seagrass organic carbon persisted for centuries.
Dataset: Blue carbon dynamics across a salt marsh-seagrass ecotone in a cool-temperate South African estuary
<p>This is a dataset of organic carbon, nitrogen, and phosphorus content from the Olifants estuary. The study was designed to investigate drivers of variability at different spatial scales and across the salt marsh-seagrass ecotone. Samples were collected in March 2023 from three selected sites (upper, middle, and lower) in the estuary. Each site featured three transects, extending from the salt marsh vegetation of mixed species through the <em>Zostera capensis</em> seagrass meadows towards the water. Sediment cores were taken to a depth of 50 cm, but only the top 0-5 cm section was analyzed. Carbon and nitrogen content were measured using an Elementar Vario EL Cube Elemental CHNS Analyzer, while phosphorus was determined by ICP at Central Analytical Facilities (Stellenbosch University).</p> <p> </p> <table> <tbody> <tr> <td> <p><strong>Sampling site</strong></p> </td> <td> <p><strong>GPS coordinates</strong></p> </td> </tr> <tr> <td> <p>Upper</p> </td> <td> <p>31°39'45.27"S, 18°11'42.40"E</p> </td> </tr> <tr> <td> <p>Middle</p> </td> <td> <p>31°40'56.46"S, 18°12'3.72"E</p> </td> </tr> <tr> <td> <p>Lower</p> </td> <td> <p>31°41'39.85"S, 18°11'15.95"E</p> </td> </tr> </tbody> </table> <p> </p> <p><strong>File description</strong></p> <p><em>CHNS_Dataset_SM&INT.xlsx</em>: Data for intermediate sample measurements including percent organic carbon content and and percent nitrogen content for all sites</p> <p><em>ICP_Data_INT.xlsx</em>: Data for Phosphorus content and other related measurements for the upper site. </p>

Data from: Blue Carbon stocks of Great Barrier Reef deep-water seagrasses
<p>Shallow-water seagrasses capture and store globally-significant quantities of organic carbon (OC), often referred to as 'Blue Carbon'; however, data is lacking on the importance of deep-water (>15 m) seagrasses as Blue Carbon sinks. We compared OC stocks from deep-, mid- and shallow-water seagrasses at Lizard Island within the Great Barrier Reef Lagoon. We found deep-water seagrasses (Halophila species) contained similar levels of OC as shallow-water species (e.g Halodule uninervis) (0.64 ± 0.08% and 0.9 ± 0.1 mg C cm3, 0.87 ± 0.19% and 1.3 ± 0.3 mg C cm3, respectively), despite being much sparser and smaller in stature. Deep-water seagrasses sediments contained significantly higher levels (~9-fold) of OC than surrounding bare areas. Inorganic carbon (CaCO3) levels were relatively high in deep-water seagrass sediments (8.2 ± 0.4%), and if precipitated from epiphytes within the meadow, could offset the potential CO2-sink capacity of these meadows. The δ13C signatures of sediment samples varied among depths and habitats (-10.9 and -17.0), reflecting contributions from autochthonous and allochthonous sources. If the OC stocks reported in this study are similar to deep-water Halophila meadows elsewhere within the GBR lagoon (total area 31,000 km2), then OC bound within this system is roughly estimated at 27.4 million tonnes.</p> <p>The dataset published in Dryad Digital Repository (<a href="http://dx.doi.org/10.5061/dryad.kj239"><span>doi:10.5061/dryad.kj239</span></a>), has been updated with the corrected data values for <span>mg <i>C</i><sub>org</sub> cm<sup>−3</sup></span>.</p>
Data from: Avoided emissions and conservation of scrub mangroves: a potential Blue Carbon project in the Gulf of California, Mexico
Mangroves are considered ideal ecosystems for Blue Carbon projects. However, because of their short stature, some mangroves ("scrub" mangroves, < 2m) do not fulfil the current definition of "forests" which makes them ineligible for emission reduction programs such as REDD+. Short stature mangroves can be the dominant form of mangroves in arid and poor nutrient landscapes, and emissions from their deforestation and degradation could be substantial. Here, we describe a potential Blue Carbon project in the Gulf of California, Mexico, to illustrate that projects which avoid emissions from deforestation and degradation could provide financial resources to protect mangroves that cannot be included in other emission reduction programs. The goal of the project is to protect 16,058 ha of mangroves through conservation concessions from the Mexican Federal Government. The cumulative avoided emissions of the project are 2.84 million Mg CO2 over 100 years, valued at $US 426,000 per year (US$15 per Mg CO2 in the California market). The funds could be used for community-based projects that will improve mangrove management, such as surveillance, eradication of invasive species, rehabilitation after tropical storms, and environmental education. The strong institutional support, secure financial status, community engagement, and clear project boundaries provide favourable conditions to implement this Blue Carbon project. Financial resources from Blue Carbon projects, even in mangroves of short stature, can provide substantial resources to enhance community resilience and mangrove protection.
A review of existing and potential blue carbon contributions to climate change mitigation in the Anthropocene
<p><span>The atmosphere concentration of CO2 is steadily increasing and causing climate change. To achieve the Paris 1.5 or 2 oC target, negative emissions technologies must be deployed in addition to reducing carbon emissions. The ocean is a large carbon sink but the potential of marine primary producers to contribute to carbon neutrality remains unclear. </span></p> <p><span>Here we review the alterations to carbon capture and sequestration of marine primary producers (including traditional 'blue carbon' plants, microalgae, and macroalgae) in the Anthropocene, and, for the first time, assess and compare the potential of various marine primary producers to carbon neutrality and climate change mitigation via biogeoengineering approaches.</span></p> <p><span>The contributions of marine primary producers to carbon sequestration have been decreasing in the Anthropocene due to the decrease in biomass driven by direct </span><span>anthropogenic activities and climate change</span><span>. The potential of blue carbon plants (mangroves, saltmarshes, and seagrasses) is limited by the available areas for their revegetation. Microalgae appear to have a large potential due to their ubiquity but how to enhance their carbon sequestration efficiency is very complex and uncertain. On the other hand, macroalgae can play an essential role in mitigating climate change through extensive offshore cultivation due to higher carbon sequestration capacity and substantial available areas. This approach seems both technically and economically feasible due to the development of offshore aquaculture and a well-established market for macroalgal products. </span></p> <p><span><em>Synthesis and applications:</em> </span><span>This paper provides new insights and suggests promising directions for utilizing marine primary producers to achieve the Paris temperature target. We propose that macroalgae cultivation can play an essential role in attaining carbon neutrality and climate change mitigation, although its ecological impacts need to be assessed further.</span></p>

The natural capital of seagrass beds in the Caribbean: evaluating their ecosystem services and blue carbon trade potential
<p class="MsoNormal">Seagrass beds provide tremendous services to society, including the storage of carbon, with important implications for climate change mitigation. Prioritizing conservation of this valuable natural capital is of global significance, and including seagrass beds in global carbon markets through projects that minimize loss, increase area, or restore degraded areas represents a mechanism towards this end. Using newly available Caribbean seagrass distribution data, we estimated carbon storage in the region and calculated economic valuations of total ecosystem services and carbon storage. We estimated the 88,170 km<sup>2</sup> of seagrass in the Caribbean stores 1,337.8 (360.5–2335.0, minimum and maximum estimates, respectively) Tg carbon. The value of these seagrass ecosystems in terms of total ecosystem services and carbon alone was estimated to be $255 billion yr<sup>-1</sup> and $88.3 billion, respectively, highlighting their potential monetary importance for the region. Our results show that Caribbean seagrass beds are globally substantial pools of carbon, and our findings underscore the importance of such evaluation schemes to promote urgently needed conservation of these highly threatened and globally important ecosystems.</p>

Data from: Blue carbon benefits from global saltmarsh restoration
<p>Coastal saltmarshes are found globally, yet are 25–50% reduced compared to their historical cover. Restoration is incentivised by the promise that marshes are efficient storers of 'blue' carbon, although the claim lacks substantiation across global contexts. We synthesised data from 431 studies to quantify the benefits of saltmarsh restoration to carbon accumulation and greenhouse gas uptake. The results showed global marshes store approximately 1.41–2.44 Pg carbon. Restored marshes had very low greenhouse gas (GHG) fluxes and rapid carbon accumulation, resulting in a mean net accumulation rate of 64.70 t CO<sub>2</sub>e ha<sup>-1</sup> y<sup>-1</sup>. Using this estimate and potential restoration rates, we find saltmarsh regeneration could result in 12.93–207.03 Mt CO<sub>2</sub>e accumulation per year, offsetting the equivalent of up to 0.51% global-energy-related CO<sub>2</sub> emissions – a substantial amount, considering marshes represent <1% of Earth's surface. Carbon accumulation rates and GHG fluxes varied contextually with temperature, rainfall and dominant vegetation, with the eastern costs of the USA and Australia being particular hotspots for carbon storage. Whilst the study reveals paucity of data for some variables and continents, suggesting a need for further research, the potential for saltmarsh restoration to offset carbon emissions is clear. The ability to facilitate natural carbon accumulation by saltmarshes now rests principally on the action of the management-policy community and on financial opportunities for supporting restoration.</p>
