High-Resolution Seismic Reflection Profiles for the Reconstruction of Postglacial Transgressive Shorelines: An example from Greece

“…With confidence we interpret this basal alluvial reflector as late Pleistocene and early Holocene land surface at lowered sea level, now buried under the sediments of the following transgression. Similar buried subaerial surfaces have been identified on other continental shelves (e.g., van Andel and Sachs, 1964;Curray and Moore, 1963 ;Moody and Van Reenan, 1967).…”

Within-marsh and Landscape Features Structure Ribbed Mussel Distribution in Georgia, USA, Marshes

“…Thus, without future research, this model cannot determine if areas like subtidal creekbanks with low densities are unsuitable habitats or the result of other processes (recruitment). Although creek banks are often the site of marsh restoration projects that might incorporate ribbed mussels in other parts of their range (Moody et al 2013), this study highlights the importance of using local data when creating species distribution models and making management decisions regarding vital coastal species. Further research on ribbed mussel demographic rates is warranted to determine why ribbed mussels exhibit the distribution pattern on the marsh platform near creek heads.…”

“…Ribbed mussels also contribute to other functions, including water filtration (Kreeger and Newell 2001), nutrient cycling (Kuenzler 1961), and habitat complexity (Newell 2004). Although historically omitted from marsh management strategies, there is increasing interest in the role that ribbed mussels can play as part of living shorelines, where they may facilitate the growth of marsh vegetation (Moody et al 2013). Given the multiple services provided by ribbed mussels and interest in their use for restoration projects, it is critical to understand the factors that might influence ribbed mussel distribution in marshes.…”

“…Due to increased interest in incorporating ribbed mussels into salt marsh management strategies (Moody et al 2013;Derksen-Hooijberg et al 2018;Kreeger et al 2018;Moody et al 2020;Bilkovic et al 2021), it is critical to examine how multiple local, marsh-scale factors, and broader, landscape-scale factors may affect mussel distribution. Therefore, the main objective of this study was to create a model of predicted ribbed mussel densities across the coast of Georgia, USA, by combining within-marsh (~ 4-m grain size, i.e., elevation, slope, distance to withinmarsh features) and landscape (500-m radius, i.e., percent cover of forested and developed areas, subtidal creeks, distance to ocean) variables.…”

Natural Gases in Marine Sediments

“…Schubel and Schiemer [l972] proposed calling such zones 'acoustically turbid' sediments, a name that is descriptive of their appearance on sub-bottom profiling records, and a name that does not have a genetic connotation. Acoustically 'turbid' sediments have been reported in large areas of the Chesapeake Bay and its tributaries [Stiles, 1970;Grim et al 1970;Schubel and Zabawa, 1972] , in Delaware Bay [Moody and van Reenan, 1967;R. Moose, personal communication, 1971], in the Hudson River (Alan Bieber, personal communication, 1970), in Long Island Sound [Grim et al 1970], in Australian estuaries, in channels of the Mekong Delta in South Vietnam [Stiles et al 1969], in a coastal pond in Massachusetts [Emery, 1969], in the Sea of Galilee in Israel [Klein and Edgerton, 1968], and in many other lakes, rivers, bays and estuaries.…”
