From The River To The Gulf: An Investigation Of Biogeochemical Cycling In Wetland Soils And Coastal Shelf Sediments, Katie Bowes
From The River To The Gulf: An Investigation Of Biogeochemical Cycling In Wetland Soils And Coastal Shelf Sediments, Katie Bowes
LSU Master's Theses
Louisiana is home to 40% of the coastal wetlands in the lower 48 states, yet accounts for 80% of the coastal wetland loss in this region. This loss is attributed to decreased sediment supply, levee alteration, sea level rise, channelization, and subsidence. The levee system in Louisiana disconnected coastal wetlands from the main stem of the Mississippi River (MSR), reducing the amount of land-building sediment that reaches coastal wetlands. This disconnection also allows a greater percentage of river discharge, including agricultural contaminants and runoff, to flow into the northern Gulf of Mexico (NGOM).
The 2012 Coastal Master Plan proposed eight …
Integrated Reservoir-Wellbore Nodal Analysis Workflow For Worst-Case Discharge Modeling, Florencia Anahi Vasquez Cordoba
Integrated Reservoir-Wellbore Nodal Analysis Workflow For Worst-Case Discharge Modeling, Florencia Anahi Vasquez Cordoba
LSU Master's Theses
According to the Bureau of Ocean Energy Management (BOEM), worst-case discharge (WCD) is the single highest possible daily flow rate of liquid hydrocarbon during an uncontrolled wellbore flow event [49]. The main objective of this research is to develop a workflow to calculate worst case discharge (WCD) volumes for a drilling scenario using an integrated reservoir-nodal analyses approach. Using robust integrated production modeling (IPM) tools, a nodal analysis workflow is developed to compute WCD volumes and rates that operators can use easily if they have IPM, or adapt to using a different software (including excel) in absence of IPM. A …
Stratigraphic Reconstruction Of A Late Pleistocene Bald Cypress Forest Discovered On The Northern Gulf Of Mexico Continental Shelf, Suyapa Michell Gonzalez Rodriguez
Stratigraphic Reconstruction Of A Late Pleistocene Bald Cypress Forest Discovered On The Northern Gulf Of Mexico Continental Shelf, Suyapa Michell Gonzalez Rodriguez
LSU Master's Theses
A previously buried bald cypress forest (Taxodium distichum) was discovered on the continental shelf, offshore of Orange Beach, Alabama, USA, in ~20 m water depth. The forest was exhumed by Hurricane Ivan in 2004, and is now exposed as stumps in life position in a trough located in the northern Gulf of Mexico continental shelf seafloor. We are investigating the local stratigraphy, paleo-landscape, and mode of forest preservation of this unique site. In August 2015 and July 2016, submersible vibracores (18 in total) were collected. Core analysis included: bulk density and imaging via Geotek multi sensor core logger, …
