Spatial Analyses And Repletion Of Gargathy Coastal Lagoon, Loreto Herraiz Gomez
Spatial Analyses And Repletion Of Gargathy Coastal Lagoon, Loreto Herraiz Gomez
OES Theses and Dissertations
Coastal lagoons and bays vary in shape and size in response to antecedent topography, geologic processes and sea level rise. Variations in shape and environmental conditions of coastal basins are believed to influence the distribution of benthic sub-environments and the exchange of water with the ocean and other adjacent coastal systems. Gargathy Inlet and its coastal lagoon vary spatially from the inlet, where the greatest depths are observed, to the mainland, dominated by shallow intertidal areas, colonized by marsh. Hypsographic and hydro-hypsographic analyses of Gargathy's coastal lagoon were the primary techniques applied to understand the relative distribution of the benthic …
Quaternary Seismic Stratigraphy Of The Inner Shelf And Coastal Zone, Southern Delmarva Peninsula, Virginia, Anthony M. Foyle
Quaternary Seismic Stratigraphy Of The Inner Shelf And Coastal Zone, Southern Delmarva Peninsula, Virginia, Anthony M. Foyle
OES Theses and Dissertations
The Pleistocene stratigraphic record beneath the Virginia inner shelf is largely unknown. On the adjacent lower Atlantic Coastal Plain of southeastern Virginia, the Pleistocene record consists of seven stacked transgressive sequences, while on the southern Delmarva Peninsula, a series of three transgressive to highstand sequences are developed. Reconstruction of the mid-Atlantic basin margin response to high-frequency Quaternary glacioeustasy is limited by this sparse record of late transgressive through early regressive deposition. Knowledge of high-frequency depositional sequence architecture, developed under conditions of low subsidence (to net uplift) and low sediment input, is also incomplete. The Atlantic inner shelf and coastal zone, …
Distribution Of Foraminifera And Pollen In Coastal Depositional Environments Of The Southern Delmarva Peninsula, Virginia, U.S.A., Han Jun Woo
OES Theses and Dissertations
The coastal zone of the southern Delmarva Peninsula exhibits a wide variety of barrier island system subenvironments. This study investigates whether 20 a priori subenvironments can be distinguished from each other on the basis of abiotic environmental variables, pollen assemblages, living foraminiferal populations, and total (living plus dead) foraminiferal assemblages.
The physical data collected from the coastal zone were subjected to canonical variate analysis which discriminated 83% of the stations in 19 groups. These groups were clustered into two internally overlapping sets which represented the inside and outside of the inlet.
Twenty-two pollen types were found in low-energy marsh and …
