We studied the food habits of canvasbacks (Aythya valisineria) at Catahoula Lake (inland) and the Mississippi River Delta (coastal), Louisiana, from November 1987 to February 1988. Plant foods comprised >97 aggregate percent dry mass of the canvasback diet. The proportion of plant material eaten did not vary with sex, age, or month, or differ between study sites or nocturnal and diurnal collections. Tubers of chufa flatsedge (Cyperus esculentus) and common arrowhead (Sagittaria latifolia) made up 94% of the canvasback diet at Catahoula Lake. Common and grassy arrowhead (Sagittaria graminea) tubers and American bulrush (Scirpus americanus) rhizomes and seeds formed 94% of the canvasback diet at the Mississippi River Delta. Consumption of specific food taxa did not vary with sex, age, or month at either study site. Canvasbacks at the Mississippi River Delta preferred seeds of American bulrush over all other foods, but American bulrush rhizomes were underrepresented in the diet. Densities of subterranean plant foods at Catahoula Lake and the Mississippi River Delta are apparently higher than at other major canvasback concentration areas and enable canvasbacks wintering in Louisiana to improve their physical condition before spring migration.

Using the Mississippi River as a tool for restoration has been a key element of restoration planning in Louisiana for decades. The results of allowing river water and sediment back into the coastal system are manifested in a number of places in present day Louisiana, with additional plans for large scale sediment and water diversions from the Mississippi River. Many previous numerical modeling studies have focused on sediment delivery to Louisiana estuaries. This study examines the effects of river diversions on salinity gradients in receiving estuarine basins. The Integrated Compartment Model, a planning-level model that simulates multi-decadal change in estuarine hydrodynamics and wetland systems under assumed sea-level rise scenarios, was used to assess the estuarine salinity gradient under potential management regimes. The simulations for current conditions are compared to a future 50-year simulation with additional diversions, as well as cases with a variety of diversion options. This modeling analysis shows that without additional action, 50-years of sea-level rise could result in substantial increases in salinity throughout the Mississippi Delta Plain estuaries. This can be largely offset with additional large river diversions which can maintain variable salinity gradients throughout the estuary basins.

ABSTRACT: The Cold War Mississippi Delta figured prominently as a hotbed of massive resistance against racial integration and as a civil rights battleground, particularly during the 1950s and 1960s. It was also home to an agrochemical regime of plantation production that heavily impacted regional ecosystems. This essay addresses the interplay between white supremacist politics and environmentally destructive forms of large-scale farming, especially the connections between petrochemical manufacturing in Louisiana and plantation agriculture in Mississippi's Delta region. I discuss how a Jim Crow mindset manifested itself in these industries, with toxic repercussions for both society and nature. The petro-multinationals that settled along the Mississippi River were active in various parts of the planet, and the crops grown on Delta neoplantations were sold on world markets, making the activities of these companies distinctly global in character. This essay considers the factories in Louisiana and the largescale farms in the Mississippi Delta as part of a unified agrochemical entity that can be considered a Plantationocene geography: a globalized business conglomerate based on a racialized labor system and an extractive, for-profit logic that was detrimental to local communities and the environment. With the arrival of oil and gas plants in Louisiana and the rise of the neoplantation during the New Deal years, an industrialized and poisonous racial ecology began to develop in the southern Mississippi River Valley wherein water, land, and minerals served as resources for the enrichment of a select few.

Sediment deprivation, hydrologic alteration, subsidence, sea level rise, and saltwater intrusion have been causing significant land loss in coastal Louisiana. Breton Sound combined with the nearby Barataria Bay, and Mississippi River Delta have lost approximately 1800 square kilometers (or 447,000 acres) of land, representing one of the highest land loss rates in the world since the 1930s when the Mississippi River was leveed. To address this problem, the Coastal Protection and Restoration Authority (CPRA) initiated several sediment diversion projects in the Lower Mississippi River (LMR). The Mid- Breton Sediment Diversion (MBrSD) project is one of the costal restoration projects proposed to restore natural processes in Breton Sound, which can strategically reestablish hydrologic flows, carry land-building sediments, nourish marshes and sustain land.

The Bird’s Foot Delta (BFD) is located at the confluence of the Mississippi River and the Gulf of Mexico in southeast Louisiana, USA. It is a 521,000-acre delta located around the three main distributaries (Southwest Pass, South Pass, and Pass-a-Loutre) off the terminal end (Head of Passes) of the Mississippi River. Here, the delta is a highly productive ecosystem that serves as a refuge for migratory birds, harbors fisheries, and acts as defense mechanism against storm surge for the city of New Orleans. Over the past several decades, the wetlands of the eastern BFD have experienced severe degradation. The primary cause of wetland loss in this area is the combination of relative sea level rise (RSLR) and decreased hydrologic connection to the Mississippi River, which results in insufficient sediment deposition and increased salinity. The BFD restoration project proposes to restore the hydrology and improve the freshwater and sediment delivery to the Eastern Bird’s Foot Delta through dredging some combination of the three largest distributaries south of Head of Passes (HOP). To inform restoration efforts, Mott MacDonald (MM) performed extensive modeling efforts to evaluate the influence of salt wedge on hydraulic and morphological patterns across the BFD.

Abstract. To plan restoration of the Mississippi River Delta, it is imperative to know how much sediment the Mississippi River currently provides. Recent research has demonstrated that between Tarbert Landing and St Francisville on the Mississippi, as much as 67 million metric tons (Mt) per year is lost from river transport, of which ~16 Mt is muddy suspended sediment. So where does this sediment go? Two pathways for loss have been proposed: riverbed storage, and overbank deposition in regions that lack manmade levées. Cat Island National Wildlife Refuge, on the unleveed Mississippi River east bank near St Francisville, Louisiana, consists of undisturbed bottomland forest that is inundated most years by river flooding. To determine fluvial sediment accumulation rates (SAR) from flooding, pushcores 40–50 cm long were collected then dated by Pb-210 and Cs-137 geochronology. Preliminary data suggests that muddy sediment accumulation is 10–13% of muddy suspended sediment lost from river transport along this river reach.

The State of Louisiana is leading an integrated wetland restoration and flood risk reduction program in the Mississippi River Delta. East of New Orleans, Biloxi Marsh, a ~1700 km2 peninsula jutting 60 km north toward the State of Mississippi is one of few Delta wetland tracts well positioned to dissipate hurricane surge and waves threatening the city’s newly rebuilt hurricane flood defenses. Both its location on the eastern margin of the Delta, and its genesis as the geologic core of the shallow water St. Bernard/Terre aux Boeuf sub-delta, which was the primary Mississippi outlet for almost 2000 years, make Biloxi Marsh attractive for restoration, now that the Mississippi River Gulf Outlet deep-draft ship channel has been dammed, and 50 years of impacts from construction and operation have abated. Now, the cascade of ecosystem damage it caused can be reversed or offset by restoration projects that leverage natural recovery and increased access to suspended sediment from the Mississippi River. Biloxi Marsh is (1) geologically stable, (2) benefiting from increased input of river sediment, and (3) could be restored to sustainability earlier and for a longer period than most of the rest of the submerging Mississippi Delta. The focus of this review is on the Biloxi Marsh, but it also provides a template for regional studies, including analysis of 2D and 3D seismic and other energy industry data to explore why existing marshes that look similar on the ground or from the air may respond to restoration measures with different levels of success. Properties of inherent durability and resilience can be exploited in restoration project selection, sequencing and expenditure. Issues encountered and investigative methods applied in the Biloxi Marsh are likely to resonate across initiatives now contemplated to sustain valuable river deltas worldwide.

Abstract. Major deltas and their adjacent coastal plains are commonly linked by means of coast-parallel fluxes of water, sediment, and nutrients. Observations of the evolution of these interlinked systems over centennial to millennial timescales are essential to understand the interaction between point sources of sediment discharge (i.e. deltaic distributaries) and adjacent coastal plains across large spatial (i.e. hundreds of kilometres) scales. This information is needed to constrain future generations of numerical models to predict coastal evolution in relation to climate change and other human activities. Here we examine the coastal plain (Chenier Plain, CP) adjacent to the Mississippi River delta, one of the world's largest deltas. We use a refined chronology based on 22 new optically stimulated luminescence and 22 new radiocarbon ages to test the hypothesis that cyclic Mississippi subdelta shifting has influenced the evolution of the adjacent CP. We show that over the past 3 kyr, accumulation rates in the CP were generally 0–1 Mt yr−1. However, between 1.2 and 0.5 ka, when the Mississippi River shifted to a position more proximal to the CP, these rates increased to 2.9 ±1.1 Mt yr−1 or 0.5–1.5 % of the total sediment load of the Mississippi River. We conclude that CP evolution during the past 3 kyr was partly a direct consequence of shifting subdeltas, in addition to changing regional sediment sources and modest rates of relative sea-level (RSL) rise. The RSL history of the CP during this time period was constrained by new limiting data points from the base of overwash deposits associated with the cheniers. These findings have implications for Mississippi River sediment diversions that are currently being planned to restore portions of this vulnerable coast. Only if such diversions are located in the western portion of the Mississippi Delta plain could they potentially contribute to sustaining the CP shoreline. Our findings highlight the importance of a better understanding of mud-dominated shorelines that are often associated with major deltas, in light of the enormous investments in coastal management and restoration that will likely be made around the globe, now and especially later during this century.

This study investigates the Louisiana 2012 Coastal Master Plan’s ability to reconcile conflicting economic and ecological demands on coastal resources. The Louisiana Coastal Master Plan was unique in combining flood control and coastal restoration under one authority. However, the objectives of flood control and coastal restoration can be in conflict. The plan was also unique in its approach of restoration from a working coast perspective. However, the objectives of ecological restoration and economic productivity do not always agree. By conducting semi-structured interviews with major coastal stakeholders, this research will explore how the planning process has accommodated the views and values of key stakeholder parties. This research aims to make more transparent the inherent environmental tradeoffs of restoration from a working coast perspective. A working coast is a compromise between economic and environmental stakeholder needs. The approach requires a balance of power to ensure that the projects selected best serve the needs of all parties. The study found that while there is industry buy in, mechanisms for mitigating economic externalities is lacking in the plan, corporate infrastructure benefits while wildlife resources are in decline.

The Louisiana oyster industry is greatly impacted by freshwater and sediment diversions that are part of the effort to restore the state’s coastline. A habitat suitability index (HSI) proposes species-habitat relationships that can be instrumental in creating impact assessments and suitability predictions for management as new diversions are implemented. An oyster (Crassostrea virginica) HSI was developed using three variables crucial to oyster sustainability: average annual salinity, minimum monthly salinity, and average salinity during the spawning season. These Legacy HSI visualizations show annual fluctuations in the distribution of zones suitable for oyster cultivation prior to proposed diversions in Pontchartrain and Barataria Basins from 1967 to 2016. Modeling suitability based upon these variables can provide crucial information for timing the use of diversions to lessen harmful effects upon the oyster industry as well as indicate new potentially suitable areas that the diversions may create.

Optically stimulated luminescence (OSL) dating beach ridge sediments is one method for resolving barrier island growth at intermediate scales (decades-centuries), information that is lacking for Louisiana. This research combines OSL, GPR, aerial imagery, and cores to document temporal and spatial evolution of a Louisiana barrier island.
Grand Isle is composed of beach ridges organized in distinct, unconformable sets that began forming 0.75 ka until 0.575 ka when deposition ceased, the ridges were partially eroded, and deposition resumed in a more eastward direction. The central ridges formed between 370±30 and 170±10 years ago at a rate of one ridge every 11.6 years with sand from the eroding Caminada headland that, with flanking barriers, forms the Bayou Lafourche transgressive depositional system. Grand Isle’s lithosome (92,600,000 cubic meters) requires an annual longshore transport of 128,625 cubic meters. The lithosome thickness (10 meters) and steady sediment supply stabilize the island relative to other Louisiana barriers.

Every thousand years or so, when the Mississippi River's sediment load lengthened and blocked the River’s route to the Gulf of Mexico, the mother stream changed course completely, finding a shorter route to the sea. Then, it built a new delta, thus spreading the gift of land creation along a wide coastline and creating the bayou region of Louisiana. However, this ancient, natural process was gradually halted by the arrival of man who settled across the River's natural floodplain (delta) and constructed levees and other structures to control the great Mississippi River. Since the 1930s, the Mississippi River Delta Basin and the coast of Louisiana have been literally losing ground. The decline of this environment is now affecting, and will continue to affect, our nation's economy, infrastructure, culture, and safety. Moreover, efforts to fix this problem are not working. My research and this thesis will address the issue of how plans without action have appeased Louisianans while the nation looses vital wetlands daily.

Palynological, lithological, loss-on-ignition, and X-ray fluorescence spectroscopy data were collected from a modified Livingstone core retrieved from Bay Jimmy, Louisiana. This data indicates a slow, general regression of the marsh due to sea level rise. This trend was punctuated by several catastrophic events including floods from around ca. 600 Yr BP and ca. 360 Yr BP, a fire around ca. 950 Yr BP, and still more flooding caused by the landfall of Hurricane Audrey in AD 1957, and Hurricanes Katrina and Rita in AD 2005. In more recent years (220 Yr BP to present) the marsh appears to have thinned out. This may be due to anthropogenic barriers, which have inhibited the marsh’s natural retreat as witnessed over the past 1200 years recorded by this core.

<em>Abstract.</em> —The magnitude of changes occurring in Louisiana’s estuaries creates a unique set of challenges in fish habitat management. Louisiana leads the nation in rate of coastal land loss, with some 70% of national losses. Both natural and anthropogenic factors are involved in coastal land loss in Louisiana: subsidence, erosion, sediment and freshwater deficits, channelization, and rising mean sea level. Disruption of the natural deltaic cycles of the Mississippi River has been particularly detrimental to estuarine fish habitat. Navigation and flood control needs have resulted in the near-total leveeing of the river, preventing normal overbank flooding, channel filling and switching, delta and subdelta development, and sediment nourishment of adjacent and down-current marshes. The resulting system is one in which the quantity and quality of estuarine habitat are linked to rapidly degrading wetland environments. Although the relative production value of subsiding marsh surfaces is often very high, this condition is not sustainable. Steep declines in fish production have been forecast for the next century. Federal, state, and local coastal restoration projects are attempting to address the loss of estuarine habitat with a number of techniques that may produce localized changes in fisheries production and distributions. Temporary resource displacements can result in increased harvest costs, and basin-scale changes may be particularly hard to accept for resource users who are satisfied with current conditions. Harvesters have demonstrated reluctance, and may lack the financial flexibility, to forfeit expected current catches for predicted enhancement of long-term fisheries production. In some instances, both sportfishers and commercial resource users have expressed concern over estuarine freshening and turbidity from restoration inputs from riverine sources. Additional public perception difficulties with restoration efforts arise from misunderstandings of the nature of estuarine functions, particularly of the importance of nursery habitat and of the value of low-salinity marshes as nursery habitat. Significant improvement in the outlook for estuarine fish habitat in Louisiana will require long-term and large-area vision from resource managers and the public.

Abstract Louisiana brings to mind pictures of a unique place-bayous, or marshy and usually sluggish tributaries to a river or lake, associated with images of a slower, more relaxed lifestyle. This part of North America also demonstrates passion in lagniappe, Mardi Gras, spicy Creole cuisine, jazz, and New Orleans with its long and unique history. All these impressions evoke memories of a good time, epitomized by Laissez les bans temps rouler! As a stronghold of French language in North America, Louisiana has maintained a distinct French colonial heritage. A closer examination of its history further shows significant Spanish and African influences. Place names such as Lac des allemands or Bayou des allemands remind one even of German settlers, who accompanied the first French colonizers to the Mississippi delta area in the early eighteenth century. Yet conspicuously absent from Louisiana’s history, as presented conventionally, has been her Native American population. The Guide to the History of Louisiana (Cummins and Jeansonne 1982) covers various periods and specific communities such as African Americans, urban New Orleans, and women, without including any systematic discussion of American Indians. In this regard, the Guide’s editors have not been unusual, for historians of the South have regularly overlooked Native Americans in the area. A common but unsupported justification for this neglect draws on arguments as to the historical insignificance of native peoples. based on the erroneous supposition that they either have perished (such as the frequently cited Natchez) or else have been removed to “the Indian Territory’’ in the Plains (like the Five Civilized Tribes of Oklahoma). Other scholars (e.g. Perdue 1988) have interpreted Native Americans of the South primarily in terms of its racist plantation history, and apparently do not recognize indigenous traditions still alive today.

Having seen pictures of the devastation did not prepare me for the reality of New Orleans. Mile after mile of wrecked houses, demolished cars, piles of debris, twisted and downed trees, and dried mud everywhere. We stopped every so often to look into abandoned houses in the 9th Ward and along the shore of Lake Pontchartrain to see things close up: mud lines on the walls, overturned furniture, moldy clothes still hanging in closets, broken toys, a lens from a pair of glasses . . . once cherished and useful objects rendered into junk. Each house had a red circle painted on the front to indicate the results of the search for bodies. Some houses showed the signs of desperation, such as holes punched through ceilings as people tried to escape rising water. The musty smell of decay was everywhere, overlaid with an oily stench. Despair hung like Spanish moss in the hot, dank July air. Ninety miles to the south, the Louisiana delta is rapidly sinking below the rising waters of the Gulf. This is no “natural” process but rather the result of decades of mismanagement of the lower Mississippi, which became federal policy after the great flood of 1927. Sediments that built the richest and most fecund wetlands in the world are now deposited off the continental shelf—part of an ill-conceived effort to tame the river. The result is that the remaining wetlands, starved for sediment, are both eroding and compacting, sinking below the water and perilously close to no return. Oil extraction has done most of the rest of the damage by crisscrossing the marshlands with channels that allow the intrusion of saltwater and storm surges. Wakes from boats have widened the original channels considerably, further unraveling the ecology of the region. The richest fishery in North America and a unique culture that once thrived in the delta are disappearing, and with them the buffer zone that protects New Orleans from hurricanes. “Every 2.7 miles of marsh grass,” in Mike Tidwell’s words, “absorbs a foot of a hurricane’s storm surge” (2003, p. 57).

With the recent exploration/discovery of deep-water reservoirs andcontinued developments of drilling and production, it remains very important to have a comprehensive and quantitative risk assessment ofthe drilling/production processes including effective response to deal with such disasters. What measures must be taken to recover from the disaster scenario of a hurricane impacting the same region in the aftermath of an oil spill? The Deepwater Horizon oil spill, the largest marine oil spill in history, was caused by an explosion on a semi-submersible drilling rig about 50 miles southeast of the Mississippi River delta on April 20, 2010. Catastrophic events such as oil spills have enormous impact for the local economy of the area and even for the local labor markets. Another regional disaster, Hurricane Katrina impacted Louisiana, Mississippi, and Alabama, as it ripped over the core of the Gulf of Mexico (GoM) producing zone, one of the important oil and gas production areas of the worldin 2005. Also, if acatastrophic disaster occurs and the emergency response supply chain is not adequately prepared, then the economic consequences of sucheventcan be huge. Whenever a disaster happens, another reaction to this event that should be considered is resiliency. It is the ability to reduce or remove potential losses due to disaster events. The impact of different shocks on various aspects of a state’s economic performance is estimated using a Vector Autoregressive model (VAR). In this study, the dynamic response of a variety of industrial sectors in Louisiana to each of these disasters is considered. The responses of different impulses in this model are shown to demonstrate the interdependence of various time series data.

Immediately after the Exxon Valdez incident, the United States Oil Pollution Act of 1990 was passed. This Act clarified the lines of responsibility associated with future oil spills. In addition to this Federal legislation, Louisiana lawmakers in 1991 enacted the Oil Spill Prevention and Response Act. Financial awards associated with this Act support a wide-range of research activities. Since 1993, 24 projects have been funded. The scope and nature of this research includes: • Oil Spill Awareness through Geoscience Education (OSAGE); • Used Oil Recycling in Louisiana’s Coastal Communities; • Evaluation and Characterization of Sorbents; • Landsat TM and Synthetic Aperture Radar to Facilitate Coastline Delineation; • Environmental Effects and Effectiveness of In-Situ Burning in Wetlands; • Bioremediation Protocol for Small-Scale Oil Spills; • Oil Spill Risk on Louisiana’s Largest Waterway; • River Time-of-Travel Modeling; • Composting Technology for Practical and Safe Remediation of Oil-Spill Residuals; • Predictability of Oceanic and Atmospheric Conditions off the Mississippi Delta; and • Phytoremediation for Oil Spill Cleanup and Habitat Restoration in Louisiana’s Marshes. Each of these projects, and others, are the result of the marriage of industry and university researchers in the identification and solution of applied oil-spill-related problems. The alliance is a good one. Important environmental issues are addressed because the selection process ensures each research initiative has the potential of being implemented by the response community. The work and knowledge gained from these projects is a clear indication of how industry and the university community can function in a collaborative manner to solve important issues — a significant partnership that clearly shows how both can benefit and a model for others to follow.
