Identifying Erosional Trends of Upper Galveston Bay Salt Marshes from 2004-2018 High Resolution Imagery: A GIS and Remote Sensing Analysis
… in presentations or modelling. In a place like Galveston Bay, Texas, coastal salt marshes and residential or urban centers coexisting near one another are commonplace, so tracking the health of the marsh based on anthropogenic actions, both conservational and detrimental, is key to preserving …

The Effects of Environmental Variability on the Population Structure of the Eastern Oyster (<i>Crassostrea virginica</i>): A Modeling Study
… of Engineers to simulate the circulation in Galveston Bay, Texas. This model provides element-averaged flow rates to the post-settlement model and element-averaged salinities to both the post-settlement and larval models. The coupled post-settlement-larval model (the oyster model) runs within …

The vulnerability of U.S. coastal energy infrastructure under climate change
… in these regions with a first application to Galveston Bay. Using future climate conditions as projected by four different Global Circulation Models (GCMs), we model the change in hurricane activity from present day climate conditions in response to a climate projected in 2100 under the IPCC A …

Impact of Patchy Vegetation on Wave and Runup Dynamics
… Selecting from a prototype in Dalehite Cove, Galveston Bay, TX, results from a Boussinesq model (COULWAVE) showed patchy vegetation reduced up to 75% mean shoreward current in the mound-channel wetland systems. These vegetation patches also reduced the primary circulation around mounds, with a …

SOIL SALINITY AND SODICITY OF GALVESTON AND PELICAN ISLANDS, TEXAS
<p>Galveston Island, Texas, is frequently affected by hurricanes. In 2008, Hurricane Ike inundated much of the island with seawater, causing elevated soil salinity levels that killed much of the vegetation on the island, including tens of thousands of trees. Residual salinity in soils and …

The response of wetlands to sea level rise: Ecologic, paleoecologic, and taphonomic models
… reactions. An analysis of these trends in the Galveston Bay system supports the following taphonomic model: During accretionary still stands, in-situ preservation is high for each thanatocoenosis. This is due to the effects of time averaging over an otherwise harsh and patchy chemical …

Sediment Dynamics and Associations with Polychlorinated Biphenyls and Dioxins in an Urban Estuary
… of PCBs and dioxins in the sediments of the Galveston Bay Estuary System (GBS) by first compiling flow, sediment, and PCB and dioxin data spanning two decades and then investigating the contaminant concentrations from a spatiotemporal perspective. Correlations revealed a significant impact of …

Modeling the Dynamics of Hypoxia and Its Interaction with Optically Active Water Quality Constituents Using Remote Sensing and Regression Analysis
… waterbodies, from freshwater streams to large bays are stressed by industrialization, population growth, and a changing climate. Hypoxia, or depressed dissolved oxygen, is one of the most ubiquitous symptoms of poor surface water quality. The ability to understand the complex interactions …

Data-Driven Method to Improve High Resolution Flood Risk Assessments
… and heavy rainfall interact. Focusing on Galveston Bay, Texas, a deep learning algorithm, convolutional neural network (CNN), specifically a U-Net algorithm, was trained to quantify the relative contributions of each flood driver and delineate flood transition zones, areas where their …

Seasonal Variation in Benthic Community Structure in Mobile Bay, Alabama.
The community concept in benthic marine ecology has long been a subject of intense interest. Peterson (1918) was one of the first investigators to recognize and attempt to characterize benthic com- munities in his extensive surveys of the Skagerrak and Baltic Sea. According to Thorson (1957), …
