Around the world, wetland vulnerability to sea-level rise (SLR) depends on different factors including tidal regimes, topography, creeks and estuary geometry, sediment availability, vegetation type, etc. The Plum Island estuary (PIE) is a mesotidal wetland system on the east coast of the United States. This research applied a newly updated Hydro-MEM (integrated hydrodynamic-marsh) model to assess the impacts of intermediate-low (50 cm), intermediate (1 m), and intermediate-high (1.5 m) SLR on marsh evolution by the year 2100. Model advancements include capturing vegetation change, inorganic and below and aboveground organic matter portion of marsh platform accretion, and mudflat creation. Although the …

Evaluation Of Monthly And Seasonal Grazing Rates Of Ilyanassa Obsoleta On Benthic Microalgae In The North Inlet Estuary, Brittany Dearmitt
Theses and Dissertations
The eastern mud snail, Ilyanassa obsoleta, is found at densities of 100’s of individuals m-2 on soft sediments in the intertidal zones of estuaries. These obligate deposit feeders consume microalgae, detritus, larvae, meiofauna, and macrofauna in the surface layers of sediments with possible trophic impacts on benthic microalgal (BMA) biomass. The goals of this study were to quantify mud snail grazing on BMA biomass, observe the variation in monthly and seasonal grazing rates, and evaluate the relationship between atmospheric temperatures and grazing rates. The sites for this experiment were two mudflats in Oyster Landing, North Inlet estuary, South …
