Organic matter content and particle size modifications in mangrove sediments as responses to sea level rise

Temporal and spatial distribution of trace metals in the Rufiji delta mangrove, Tanzania

“…The sediment grain size rich in clay and silt fractions reflects that the large surface area of fine particles (sediment-specific surface area) results in greater sorption of OM to sediments. In addition, variation of OM content with depth is also affected by mineralization as part of the early diagenetic changes (Sanders et al 2012), after the sediments are deposited.…”

Examining 239+240 Pu, 210 Pb and historical events to determine carbon, nitrogen and phosphorus burial in mangrove sediments of Moreton Bay, Australia

“…This sediment dating method is particularly useful to interpret the effects of climate change (Chen et al, 2014;Mabit et al, 2014), sea level rise (Gehrels et al, 2012;Sanders et al, 2012;Smoak et al, 2013) and in studies determining environmental impacts during the previous century (Figueiredo et al, 2013;Harmon et al, 2014;Raygoza-Viera et al, 2014;Reinemann et al, 2014;Sanders et al, 2006). Indeed, the 210 Pb dating method has been used to date coastal sediments for more than 40 years (Koide et al, 1973), including carbon burial rates in coastal wetlands (Sanders et al, 2010a;Weston et al, 2014).…”

Mangrove vegetation changes on Holocene terraces of the Doce River, southeastern Brazil

“…The expansion or contraction of mangrove areas is dependent on temperature, soil type, salinity, inundation frequency, sediment accretion, tidal and wave energy (Lugo and Snedaker, 1974). Specifically the mangrove has special physiological and morphological adaptations that allow it to grow in intertidal environments (Alongi, 2008;Blasco et al, 1996;Cahoon and Lynch, 1997;Sanders et al, 2012). Thus this ecosystem may be used as an indicator of coastal change and RSL fluctuations (Blasco et al, 1996).…”
