Quantification of blue carbon stocks associated with Posidonia oceanica seagrass meadows in Corsica (NW Mediterranean)
2022, Science of the Total EnvironmentCitation Excerpt :Thus, an increase in seagrass canopy complexity (i.e. density, cover and biomass) contributed generally to the reduction of hydrodynamic energy resulting in higher trapping and retention of fine-grained sediment particles (i.e. silt and clay) from the water column, and consequently leading to higher sediment accretion rates (SAR) (Gacia and Duarte, 2001; Hendriks et al., 2008; Samper-Villarreal et al., 2016; Serrano et al., 2016b; Monnier et al., 2021b). Concurrently, the higher deposition of fine sediment particles and SAR of seagrass soils may contribute to an increase in Corg burial rates and preservation (Keil and Hedges, 1993; Burdige, 2007) due to reduced oxygen exposure time occurring in fine sediments (Hedges and Keil, 1995; Mateo et al., 2006; Burdige, 2007; Pedersen et al., 2011). Recently, the P. oceanica primary production and Corg sequestration along depth-related gradients were assessed within the study area (Pergent-Martini et al., 2020).
The first national scale evaluation of total nitrogen stocks and burial rates of intertidal sediments along the entire coast of South Korea
2022, Science of the Total EnvironmentCitation Excerpt :Similar geochemical characteristics of N stocks have been previously reported for sediments in the Yellow Sea (Lü et al., 2005). Further, the relationship between mud (silt-clay) content and organic matter has been widely documented in other marine environments around the world (Dunn et al., 2017; Keil and Hedges, 1993; Kindeberg et al., 2018; Serrano et al., 2016), supporting sediment mud content as a universal proxy for estimating sedimentary total N stocks in the present study area and elsewhere. The estimation of total N stocks (Table S6) and N burial rates (Table S7) in sand-, mixed-, and mud-dominated sediments were estimated using sedimentary total N stock per unit tidal flat area based on sediment type.
The first national scale evaluation of organic carbon stocks and sequestration rates of coastal sediments along the West Sea, South Sea, and East Sea of South Korea
2021, Science of the Total EnvironmentCitation Excerpt :The positive relationship between mud and organic carbon content has been repeatedly documented (Keil and Hedges, 1993; Mayer, 1994; Bergamaschi et al., 1997; Flemming and Delafontaine, 2000; Burdige, 2007; Serrano et al., 2016). This relationship is attributed to the larger surface area of fine-grained sediments (e.g., mud) compared to coarse-grained sediments (e.g., sand), providing more binding sites for sedimentary organic carbon (Keil and Hedges, 1993; Mayer, 1994; Burdige, 2007; Serrano et al., 2016). Therefore, mud content could be used as a universal proxy for estimating sedimentary organic carbon by applying each relationship equation of bare tidal flats and salt marshes in different provinces of South Korea.
