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...
The recent focus on carbon trading has intensified interest in ‘Blue Carbon’–carbon sequestered by coastal vegetated ecosystems, particularly seagrasses. Most information seagrass storage is derived from studies of a single species, Posidonia oceanica, the Mediterranean Sea. We surveyed 17 Australian habitats to assess variability their sedimentary organic (Corg) stocks. encompassed 10 mono-specific or mixed meadows, depositional exposed and temperate tropical habitats. There was an 18-fold...
Abstract Calcium carbonates (CaCO 3 ) often accumulate in mangrove and seagrass sediments. As CaCO production emits CO 2 , there is concern that this may partially offset the role of Blue Carbon ecosystems as sinks through burial organic carbon (C org ). A global collection data on inorganic rates inorg 12% mass) revealed 0.8 TgC yr −1 15–62 ecosystems, respectively. In seagrass, correspond to an 30% net sequestration. However, a mass balance assessment highlights C mainly supported by...
Plastic pollution is emerging as a potential threat to the marine environment. In current study, we selected seagrass meadows, known efficiently trap organic and inorganic particles, investigate concentrations dynamics of microplastics in their soil. We assessed microplastic contamination accumulation

Abstract. There has been growing interest in quantifying the capacity of seagrass ecosystems to act as carbon sinks a natural way offsetting anthropogenic emissions atmosphere. However, most efforts have focused on particulate organic (POC) stocks and accumulation rates ignored inorganic (PIC) fraction, despite important carbonate pools associated with calcifying organisms inhabiting meadows, such epiphytes benthic invertebrates, relevance that precipitation dissolution processes global...
Abstract The actual estimates of carbon stocks beneath seagrass meadows worldwide are derived from few data, resulting in a tendency to generalize global very limited number habitats.

This synopsis focuses on the effects of climate change Mediterranean seagrasses, and associated communities, contribution main species, Posidonia oceanica, to mitigation through its role sequestering carbon dioxide.

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...

Posidonia oceanica is a widespread coastal Mediterranean seagrass which accumulates in its subsurface large quantities of organic material derived from roots, rhizomes and leaf sheaths embedded sandy sediments. These deposits may be up to several meters thick as they accumulate over thousands years forming the matte , whose high content carbon plays major role global ocean cycle. In this study, very high‐resolution seismo‐acoustic methods were applied image features P. meadow at Portlligat...
Abstract. The ecosystem associated to the Mediterranean seagrass Posidonia oceanica shows a clear distinction in two subcompartments regarding turnover time: aboveground and belowground. Aboveground parts (leaves) are highly dynamic, most of leaf material is decomposed or exported less than one year, representing net loss nutrients. In contrast, belowground biomass (roots rhizomes) has time order centuries, with consequent accumulation organic matter sediment. rates for single elements rank...
