Abstract Policies aiming to preserve vegetated coastal ecosystems (VCE; tidal marshes, mangroves and seagrasses) mitigate greenhouse gas emissions require national assessments of blue carbon resources. Here, we present organic (C) storage in VCE across Australian climate regions estimate potential annual CO 2 emission benefits conservation restoration. Australia contributes 5–11% the C stored globally (70–185 Tg aboveground biomass, 1,055–1,540 upper 1 m soils). Potential from current losses...
With the growing recognition that effective action on climate change will require a combination of emissions reductions and carbon sequestration, protecting, enhancing restoring natural sinks have become political priorities. Mangrove forests are considered some most carbon-dense ecosystems in world with stored soil. In order for mangrove to be included mitigation efforts, knowledge spatial distribution soil stocks critical. Current global estimates do not capture enough finer scale...
Abstract Australia’s tidal marshes have suffered significant losses but their recently recognised importance in CO 2 sequestration is creating opportunities for protection and restoration. We compiled all available data on soil organic carbon (OC) storage (323 cores). OC stocks the surface 1 m averaged 165.41 (SE 6.96) Mg ha −1 (range 14–963 ). The mean accumulation rate was 0.55 ± 0.02 yr . Geomorphology most important predictor of stocks, with fluvial sites having twice stock as seaward...
Tidal marshes store large amounts of organic carbon in their soils. Field data quantifying soil (SOC) stocks provide an important resource for researchers, natural managers, and policy-makers working towards the protection, restoration, valuation these ecosystems. We collated a global dataset tidal marsh (MarSOC) from 99 studies that includes location, depth, site name, dry bulk density, SOC, and/or matter (SOM). The MarSOC 17,454 points 2,329 unique locations, 29 countries. generated...
Abstract Mangroves, tidal marshes and seagrasses have experienced extensive historical reduction in extent due to direct indirect effects of anthropogenic land use change. Habitat loss has contributed carbon emissions led foregone opportunities for sequestration, which are disproportionately large high ‘blue carbon’ stocks sequestration rates these coastal ecosystems. As such, there been a rapid increase interest using habitat restoration as climate change mitigation tool. This review shows...
Abstract. Tidal marshes, mangrove forests, and seagrass meadows are important global carbon (C) sinks, commonly referred to as coastal “blue carbon”. However, these ecosystems rapidly declining with little understanding of what drives the magnitude variability C associated them, making strategic effective management blue stocks challenging. In this study, our aims were threefold: (1) identify ecological, geomorphological, anthropogenic variables 30 cm deep sediment stock in southeastern...
Intensive macroalgal blooms, a source of labile organic carbon (LOC) induced by coastal nutrient loading in some seagrass ecosystems, create ideal conditions for enhanced recalcitrant (ROC) loss via the cometabolism effect. Here, we carried out 62-day laboratory experiment to see if density-dependent addition biomass can influence decomposition process, including detritus chemistry, greenhouse emissions, and bacterial communities. We found that higher density stimulated microbes decompose...
Sediment dynamics in seagrass meadows are key determinants of carbon sequestration and storage, surface elevation, resilience recovery from disturbance. However, current methods for measuring sediment accumulation limited. For example, 210 Pb dating, the most popular tool quantifying accretion rates over decadal timescales, relies on assumptions often at odds with meadows. Here, we have developed a novel subsurface plate method to detect changes erosion real time that: 1) is affordable...
Abstract Net global losses of seagrasses have accelerated efforts to understand recovery from disturbances. Stressors causing disturbances (e.g., storms, heatwaves, boating) vary temporally and spatially within meadows potentially affecting recovery. To test differential recovery, we conducted a removal experiment at sites that differed in thermal stress for temperate seagrass ( Zostera marina ). We also synthesized prior studies assess general patterns. Seagrass shoots were removed 28.3 m 2...
Seagrass beds have decreased in abundance and areal coverage over the past several decades. Although previous studies examined importance of seagrass for benthic community assemblages abundances, effect on deep-dwelling, large (high-biomass) infauna secondary production Chesapeake Bay not been addressed. Using suctions push cores, we compared density, diversity, productivity communities to those other shallow-water habitats estimated lost York River due loss from 1971 2016. We four habitat...
