Latest Quaternary Stratigraphic Framework of the Mississippi River Delta Region Latest Quaternary Stratigraphic Framework of the Mississippi River Delta Region Kulp, Mark,1 Howell, Paul,2 Adiau, Sandra,2 Penland, Shea,1 Kindinger, Jack,3 and Williams, S. Jeffress4 1Coastal Research Laboratory University of New Orleans, New Orleans, Louisiana 70148 2Department of Geological Sciences, University of Kentucky, Lexington, Kentucky 40503 3United States Geological Survey, Coastal and Marine Geology Program, Woods Hole, Massachusetts 02543 4United States Geological Survey, Center for Coastal and Regional Marine Studies, St. Petersburg, Florida 33701 Abstract Previous researchers separated the uppermost Quaternary stratigraphy of the Mississippi River delta region into two major lithofacies. The stratigraphically lower of these, “substratum,” primarily consists of coarse-grained sediment deposited within lowstand-incised stream valleys. Relatively finer-grained “topstra- tum” overlies substratum; above interfluves, topstratum directly overlies weathered late Pleistocene sediments. However, the onshore to offshore distribution and architecture of these lithofacies was not well con- strained. This study integrates published and unpublished lithostratigraphic data with high-resolution seismic profiles from the continental shelf to aid in mapping the regional distribution of major substratum deposits and thickness of topstratum sediments. A transgressive sand sheet commonly marks the base of the topstratum deposits, providing a stratigraphic marker to aid in regional lithostratigraphic correlations. Radiocarbon- dated deposits and boreholes tied to oxygen isotope chronologies provide chronostratigraphic control. Excel- lent correlation between these multiple datasets has been found to exist, enabling construction of regional isopachous and structural elevation maps and cross sections detailing elements of the Late Quaternary stratigraphy. Introduction Upper Quaternary stratigraphic relationships in the Mississippi River delta region, north-central Gulf of Mex- ico, have been a topic of investigation for at least five decades (e.g., Fisk, 1944; Kolb and van Lopik, 1958; Frazier, 1967; Suter 1986), contributing significantly toward current knowledge of sedimentation patterns on fluvio-deltaic dominated, continental margins and the associated role of glacio-eustatic fluctuations. The most recent, regional stud- ies covering both the onshore and offshore Late Quaternary (latest Wisconsinan-Holocene) stratigraphy date from the seminal work of Fisk and colleagues (Fisk, 1944; Fisk and McFarlan, 1955; McFarlan, 1961). However, subsequent investigations have been more geographically restricted (e.g., Coleman and Roberts, 1988a; Kindinger, 1988; Stanley et al., 1996; Sydrow and Roberts, 1996) and, despite the availability of appropriate data, a full onshore-to-off- shore linkage of latest Quaternary stratigraphic units has not been previously completed. This study builds upon and expands earlier findings by integrating published and unpublished stratigraphic data sets to establish a regional, onshore-offshore lithostratigraphic correlation of uppermost Quaternary sediments of the region. Several thousand kilometers of high-resolution seismic reflection profiles, more than 800 onshore and offshore boreholes, and numer- ous cross sections spanning 50 years of research constitute the database. The strata of primary interest in this paper have been deposited since a late Wisconsinan lowstand of approxi- mately 120 m (394 ft) below modern sea level 18,000 yr B.P. (Fairbanks, 1989). This dominantly fine-grained interval is herein termed the “topstratum lithosome,” specifically building upon the work of Fisk (1944) who lithostratigraph- ically differentiated the uppermost Quaternary stratigraphy. Fisk’s stratigraphically youngest, fine-grained topstratum represented deposition in fluvial, deltaic, and shelf environments concomitant with and subsequent to full marine flooding of the continental shelf following the latest Wisconsinan lowstand, whereas the subjacent, coarser-grained substratum was suggestive of fluvial deposition within lowstand river valleys. More clearly defining the distribution Gulf Coast Association of Geological Societies Transactions, Volume 52, 2002 573 Kulp et al. and character of these lithofacies is critical to future stratigraphic studies and to an evaluation of existing models that describe the regional late Quaternary sedimentation patterns. Latest Quaternary Sedimentary Response During the late Wisconsinan sea-level fall, drainage systems of the northern Gulf basin responded by extending across the continental shelf and/or incising into older sediments (Fisk, 1944; Suter, 1986; Kindinger, 1988). Subaerial exposure at maximum lowstand created an expanded coastal plain; point-source fluvial delivery to the outer shelf and upper slope created offlapping, shelf-edge deltaic sequences between 60 m and 150 m (197 ft and 492 ft) thick (Suter, 1986; Kindinger, 1988; Sydrow and Roberts, 1996). Subaerial exposure and pedogenetic processes within stream val- leys and on interfluves created mature soil profiles (Fisk, 1944; Kolb and Van Lopik, 1958; Morton and Price, 1987). Color-mottled, silt-rich clay and clay-rich silt of yellow-brown, reddish-brown, and gray hues; calcareous concre- tions; crack-fills; root traces; and Fe/Mn oxide lenses lithologically distinguish the level of subaerial weathering (Fisk, 1944; Stanley et al., 1996; Sydrow and Roberts, 1996). Historically, this weathered horizon has been referred to as the “Prairie surface” because of suggested updip correlation to a coast-parallel outcrop of the late Pleistocene Prai- rie Formation (Fisk and McFarlan, 1955). The erosional surface created above Pleistocene strata is referred to here as the late Wisconsinan unconformity (sensu Stanley et al., 1996). Toward the late Wisconsinan shelfbreak, where shorter or nonexistent exposure produced an ill-defined erosional surface, the unconformity is difficult to discern; downdip of the late Wisconsinan shelf break the surface is a poorly defined correlative conformity below shelf-edge deltaic strata (Suter, 1986; Sydrow and Roberts, 1996). This study addresses the sedimentary package deposited shoreward of the late Wisconsinan shelf-edge. Substratum Shelf deposition during the late Wisconsinan lowstand and early sea-level rise was primarily restricted to incised valleys within braided fluvial systems (Fisk and McFarlan, 1955; Coleman et al., 1991). This depositional phase produced a lithologically distinct unit, dominated by gravel and sand-rich sediments referred to as substratum (Fisk, 1944). Grain-size analysis of multiple lithofacies above the late Wisconsinan unconformity has revealed that only substratum contains sediments with a coarsest first percentile greater than 350 µm (Kuecher, 1994). Substratum deposits are not well studied but generally exhibit a fining-upward stratigraphy (Saucier, 1994). Topstratum Lowstand, braided fluvial systems adjusted to subsequent base-level rise by evolving toward meandering regimes (Coleman et al., 1991). Maturation of backswamp and floodplain environments enhanced aggradational depo- sition, likely accounting for the upward-fining grain size of the substratum interval. Organic-rich and fine-grained sediments of brackish origin above coarse-grained, channel-fill sediments typically indicate initial drowning, inception of estuarine environments, and a major depositional change within progressively flooded stream valleys (Suter et al., 1987; Sydrow and Roberts, 1996). Above interfluves, this marine incursion is marked by a marine ravinement and/or transgressive marine facies created during marine reworking of underlying sediments at the transgressing shoreline. The transgressive marine facies has been referred to as nearshore Gulf facies, bay-sound facies, transgressive sand sheet, and a coalesced strandplain deposit (Kolb and Van Lopik, 1958; Frazier, 1974; May et al., 1984; Stanley et al., 1996). From the modern birdfoot depocenter (Balize subdelta) to below New Orleans, the lithofacies consists of shell-rich, sandy and silty sediment that exists as a locally continuous “sheet,” as well as infill of local topography on the underlying unconformity. Fine-grained, shell-rich sediment below the Balize depocenter passes northward into sandier and more silt-rich sediment, the facies terminates northward as shell and mud-rich sediment at a mid-Holocene, beach/barrier sand (Pine Island Beach Trend) near New Orleans (Saucier, 1994; Stanley et al., 1996). Radiocarbon-dated shells within the facies below the Balize depocenter indicate a maximum age of 15,500 yr B.P. for the lithofacies (Morgan et al., 1963), whereas dates from the Pine Island Beach Trend range from 5,500 to 6,000 yr B.P. (Saucier, 1994). Below chenier-plain deposits of the western Louisiana coastline the facies has been dated at between 4,500 and 6,000 yr B.P. (Coleman, 1966). Progradation of Mississippi River-fed deltaic complexes has resulted in burial of the basal transgressive facies across much of the northern shelf, creating a regressive sequence of deltaic deposits above the transgressive facies and/or marine ravinement. Initial progradation of Holocene deltas from the western margin of the Mississippi alluvial valley (Maringouin/Teche delta plain) began by at least 7,000 yrs B.P. (Frazier, 1974; Boyd et al., 1989). Although 574 Latest Quaternary Stratigraphic Framework of the Mississippi River Delta Region earlier deltaic strata have been suggested to exist on the central mid shelf, burial and

Paradoxically, despite a long history of inquiry into spit and barrier formation, understanding of the dynamics and sedimentary history of tombolos over the Holocene timescale is poor. At Tyre and Alexandria we demonstrate that these rare coastal features are the heritage of a long history of natural morphodynamic forcing and human impacts. In 332 BC, following a protracted seven-month siege of the city, Alexander the Great's engineers cleverly exploited a shallow sublittoral sand bank to seize the island fortress; Tyre's causeway served as a prototype for Alexandria's Heptastadium built a few months later. We report stratigraphic and geomorphological data from the two sand spits, proposing a chronostratigraphic model of tombolo evolution. © 2008 Elsevier B.V. All rights reserved.

Received: 20 April 2020; Accepted: 20 May 2020; Published: 23 May 2020 Abstract: Oil and gas (O&G) activity has been pervasive in the Mississippi River Delta (MRD). Here we review the life cycle of O&G fields in the MRD focusing on the production history and resulting environmental impacts and show how cumulative impacts affect coastal ecosystems. Individual fields can last 40–60 years and most wells are in the final stages of production. Production increased rapidly reaching a peak around 1970 and then declined. Produced water lagged O&G and was generally higher during declining O&G production, making up about 70% of total liquids. Much of the wetland loss in the delta is associated with O&G activities. These have contributed in three major ways to wetland loss including alteration of surface hydrology, induced subsidence due to fluids removal and fault activation, and toxic stress due to spilled oil and produced water.

  • Alaska Peninsula and Becharof
    U.S. Fish & Wildlife Service Alaska Peninsula and Becharof National Wildlife Refuge Bird List Covering approximately 4.6 million acres (larger than Connecticut and Rhode Island combined), the Alaska Peninsula/Becharof National Wildlife Refuge includes an immense variety of Peregrine Falcon ©Rod Cyr habitats and is home to more than 200 species of birds. Established in 1980, the Refuge conserves fish and wildlife populations and habitats in their natural diversity. Introduction The Alaska Peninsula/Becharof National Wildlife Refuge is a long, thin refuge; reaching from the Gulf of Alaska coast, over the Aleutian Mountains and a number of large inland lakes, to the middle of the Bristol Bay Coastal Plain. The Refuge stretches from the Katmai National Park’s southern boundary to American Bay on the Gulf of Alaska and Port Moller on the Bristol Bay coast, and is interrupted by Aniakchak National Monument and Preserve. Becharof Lake, completely within Becharof NWR, is the largest lake in the wildlife refuge system. The landscape is shaped by the Pacific Ocean, active volcanoes and glaciers, meandering rivers and sub- arctic weather cells. Habitats include near-shore marine, coastal shores and cliffs, alpine tundra, forest, shrub and a mostly treeless tundra/ shrubland/wetland complex at lower elevations. This diversity of the Refuge’s landforms and habitats contributes to a diverse avifauna. Starting at the Gulf of Alaska, coastal waters support a variety of seabirds, other cliff dependent species, and wintering waterfowl. The land rises sharply to the Aleutian Mountains, where alpine species of landbirds, shorebirds, cliff nesting raptors, and the elusive Kittlitz’s Murrelet find homes.
